Rather than guessing at improvements, these workflows use structured experimentation and data-driven decision-making to evolve prompts from initial drafts to production-ready implementations. + +## Why This Matters for AI-First Development + +In AI-first systems, prompts are the primary interface for instructing AI agents, making their quality critical to system reliability. Unlike traditional code where bugs are often deterministic and reproducible, prompt-related issues can be subtle, context-dependent, and emergent. A prompt that works perfectly in testing might fail unpredictably in production, or degrade over time as model versions change or use cases evolve. + +Without systematic iteration workflows, three critical problems emerge: + +1. **Inability to measure improvement**: Teams make prompt changes based on intuition or cherry-picked examples rather than systematic evaluation. This leads to changes that improve some cases while breaking others, with no objective way to determine if the overall quality improved. What seems like a "small improvement" might actually degrade performance across the broader test set. + +2. **No reproducibility of results**: When prompt development happens ad-hoc without documented iterations, successful prompts become "lucky accidents" that can't be replicated or explained. If a prompt starts failing, teams can't trace back through the iteration history to understand what worked and why, making debugging nearly impossible. + +3. **Compounding of small errors**: Without systematic testing between iterations, small issues accumulate. Each "quick fix" introduces subtle regressions that go unnoticed until the prompt becomes unreliable. By the time problems surface in production, the prompt has drifted so far from its original design that fixing it requires starting over. + +Systematic iteration workflows solve these problems by treating prompt development like software engineering: each iteration is documented, tested against a suite of examples, measured objectively, and only deployed if it demonstrates improvement.

This principle defines the evaluation framework. + +## Common Pitfalls + +1. **Iterating Without a Test Set**: Making prompt changes without a comprehensive test set to measure impact. + - Example: Tweaking a prompt based on one failing example without checking if the change breaks other cases. + - Impact: Changes that improve one case while degrading overall performance, with no way to detect the regression until production failures. + +2. **Cherry-Picking Test Cases**: Selecting test cases that show improvement while ignoring cases that got worse. + - Example: Running tests on 100 cases, focusing on the 20 that improved, ignoring the 30 that degraded. + - Impact: False confidence in improvements that actually hurt overall quality. Leads to deploying worse prompts thinking they're better. + +3. **No Statistical Validation**: Treating small differences as meaningful without checking if they're statistically significant. + - Example: Deploying a prompt that scored 0.78 instead of 0.76 on 5 test cases, assuming it's better when the difference could be random noise. + - Impact: Chasing phantom improvements, wasting time on changes that don't actually help, inability to distinguish signal from noise. + +4. **Iterating on Too Small a Sample**: Drawing conclusions from insufficient test data. + - Example: A/B testing two prompts on 3 examples and choosing the winner. + - Impact: Selected "winner" might perform worse on broader test set, leading to production failures. + +5. **No Stopping Criteria**: Continuing to iterate without clear goals or stopping conditions. + - Example: Spending days iterating to improve score from 0.94 to 0.95 when 0.90 was sufficient. + - Impact: Wasted resources on marginal improvements, diminishing returns, opportunity cost of not working on more impactful improvements. + +6. **Undocumented Iterations**: Not recording what was tried, what worked, and why. + - Example: Trying 10 prompt variations, keeping one, with no record of what the other 9 were or why they failed. + - Impact: Can't learn from past iterations, rediscover same dead ends, unable to rollback when problems occur. + +7. **Single-Dimensional Optimization**: Optimizing only for accuracy while ignoring cost, latency, or safety. + - Example: Improving accuracy from 85% to 90% by adding examples that triple response time and cost. + - Impact: "Better" prompts that can't be used in production due to cost or latency constraints, misalignment with real-world requirements. + +## Tools & Frameworks + +### Prompt Testing Frameworks +- **PromptTools**: Open-source library for testing and evaluating prompts across different models with A/B testing support +- **OpenAI Evals**: Framework for evaluating LLM outputs with built-in metrics and custom evaluators +- **LangSmith**: Platform for testing, evaluating, and monitoring LLM applications with prompt versioning + +### Statistical Analysis Tools +- **scipy.stats**: Python library for statistical significance testing (t-tests, ANOVA, etc.) +- **pandas**: For organizing test results and calculating metrics across iterations +- **matplotlib/seaborn**: Visualizing iteration history and performance trends + +### Evaluation Platforms +- **Weights & Biases Prompts**: Experiment tracking for prompts with versioning and comparison tools +- **Humanloop**: Platform for prompt iteration with human feedback loops and evaluation +- **Braintrust**: Evaluation and monitoring platform specifically for AI applications + +### Version Control +- **Git**: Standard version control for tracking prompt changes over time +- **DVC**: Data Version Control for tracking test datasets alongside prompt versions +- **Prompt registries**: Custom systems for storing and versioning prompt templates + +### A/B Testing Tools +- **Statsig**: Experimentation platform that can be used for prompt A/B testing +- **Split.io**: Feature flagging and experimentation for gradual prompt rollouts +- **Custom frameworks**: Many teams build custom A/B testing on top of their prompt serving layer + +### Monitoring and Analytics +- **Prometheus/Grafana**: For tracking prompt performance metrics in production +- **Datadog**: Application monitoring with support for custom metrics from prompt systems +- **Amplitude**: Product analytics for understanding how prompt changes affect user behavior + +## Implementation Checklist + +When implementing this principle, ensure: + +- [ ] Comprehensive test set covers diverse inputs including edge cases and failure modes +- [ ] Baseline performance is measured and documented before any iterations begin +- [ ] Each iteration is tested against the full test set, not cherry-picked examples +- [ ] Objective metrics are defined for measuring prompt quality (not subjective assessment) +- [ ] Iteration decisions are data-driven with statistical validation where appropriate +- [ ] Every iteration is documented with version, test results, reasoning, and decision +- [ ] A/B tests use sufficient sample size (typically 30+ examples minimum) for statistical power +- [ ] Multiple dimensions are tracked (accuracy, latency, cost, safety) not just accuracy +- [ ] Clear stopping criteria are defined before iteration begins (target score, max iterations, diminishing returns threshold) +- [ ] Iteration history is preserved enabling rollback to any previous version +- [ ] Best practices from successful iterations are captured as reusable patterns +- [ ] Iteration workflow is integrated into CI/CD pipeline for continuous improvement + +## Metadata + +**Category**: Process +**Principle Number**: 53 +**Related Patterns**: Test-Driven Development, A/B Testing, Continuous Improvement, Gradient Descent Optimization, Statistical Hypothesis Testing +**Prerequisites**: Version control system, comprehensive test suite, evaluation metrics, basic statistical knowledge +**Difficulty**: Medium +**Impact**: High + +--- + +**Status**: Complete +**Last Updated**: 2025-09-30 +**Version**: 1.0 diff --git a/ai-first-principles/principles/process/54-context-curation-pipelines.md b/ai-first-principles/principles/process/54-context-curation-pipelines.md new file mode 100644 index 00000000..8ddd9828 --- /dev/null +++ b/ai-first-principles/principles/process/54-context-curation-pipelines.md @@ -0,0 +1,901 @@ +# Principle #54 - Context Curation Pipelines + +## Plain-Language Definition + +Context curation pipelines are systematic workflows that prepare, validate, enrich, and maintain the context provided to AI systems. Instead of haphazardly assembling context at query time, these pipelines ensure that context is high-quality, relevant, properly formatted, and continuously improved through automated processing stages. + +## Why This Matters for AI-First Development + +AI agents are only as good as the context they receive. Poor context leads to hallucinations, irrelevant responses, incorrect code generation, and wasted API calls. When humans manually curate context, it's inconsistent, time-consuming, and doesn't scale. When AI agents create their own context on-the-fly, they lack the systematic quality controls needed for production systems. + +Context curation pipelines solve this by treating context preparation as a first-class engineering discipline: + +1. **Quality at scale**: Pipelines enforce consistent quality checks across thousands of documents, code files, or data records. Every piece of context goes through the same validation, cleaning, and enrichment stages, ensuring uniform quality regardless of volume. + +2. **Continuous improvement**: Pipelines enable feedback loops where context quality is measured, analyzed, and automatically improved. When AI responses fail or underperform, the pipeline can trace back to specific context issues and remediate them systematically. + +3. **Cost optimization**: Well-curated context reduces token waste by removing redundancy, improving relevance, and enabling better retrieval. Pipelines can compress, summarize, and filter context intelligently, reducing API costs while maintaining or improving response quality. + +Without curation pipelines, context management becomes reactive and error-prone. Teams manually fix context issues one at a time, never addressing root causes. Context quality degrades as systems evolve. AI agents work with stale, poorly formatted, or irrelevant information. Token budgets are consumed by noise. Response quality varies unpredictably based on whatever context happened to be available. + +Context curation pipelines transform context from an afterthought into a managed asset. They ensure that every piece of information an AI agent sees has been cleaned, validated, enriched with relevant metadata, and proven to produce good results. This systematic approach is essential when AI agents operate autonomouslyβ€”they need trustworthy, well-prepared context to make good decisions without human oversight. + +## Implementation Approaches + +### 1. **Multi-Stage Preprocessing Pipeline** + +Build a pipeline with distinct stages for cleaning, validation, enrichment, and indexing: + +```python +def curate_document_context(raw_docs: list[Document]) -> list[CuratedDocument]: + """Multi-stage context curation pipeline""" + + # Stage 1: Clean and normalize + cleaned = [clean_document(doc) for doc in raw_docs] + + # Stage 2: Validate quality + validated = [doc for doc in cleaned if validate_quality(doc)] + + # Stage 3: Enrich with metadata + enriched = [enrich_metadata(doc) for doc in validated] + + # Stage 4: Generate contextual embeddings + embedded = [generate_contextual_embedding(doc) for doc in enriched] + + # Stage 5: Index for retrieval + indexed = [index_for_search(doc) for doc in embedded] + + return indexed + +def clean_document(doc: Document) -> Document: + """Remove noise, fix formatting, normalize structure""" + # Remove excessive whitespace + text = re.sub(r'\s+', ' ', doc.text) + # Fix encoding issues + text = text.encode('utf-8', errors='ignore').decode('utf-8') + # Normalize line breaks + text = text.replace('\r\n', '\n') + return Document(text=text, metadata=doc.metadata) + +def validate_quality(doc: Document) -> bool: + """Ensure document meets quality thresholds""" + if len(doc.text) < 50: # Too short + return False + if doc.text.count(' ') / len(doc.text) < 0.1: # Not enough spaces (likely corrupted) + return False + if not any(c.isalpha() for c in doc.text): # No alphabetic characters + return False + return True + +def enrich_metadata(doc: Document) -> Document: + """Add contextual metadata for better retrieval""" + doc.metadata['word_count'] = len(doc.text.split()) + doc.metadata['topics'] = extract_topics(doc.text) + doc.metadata['entities'] = extract_entities(doc.text) + doc.metadata['curated_at'] = datetime.now().isoformat() + return doc +``` + +**When to use:** Large-scale document processing, RAG system preparation, knowledge base construction. + +**Success looks like:** Consistent quality across all documents, automatic rejection of low-quality content, enriched metadata enabling better retrieval. + +### 2. **Contextual Chunking with Overlap** + +Chunk documents intelligently while preserving context across boundaries: + +```python +def create_contextual_chunks( + document: str, + chunk_size: int = 500, + overlap: int = 100, + add_document_context: bool = True +) -> list[Chunk]: + """Create chunks with contextual information""" + + # Extract document-level context + doc_context = generate_document_summary(document) + + chunks = [] + words = document.split() + + for i in range(0, len(words), chunk_size -

Six months later, AI gives outdated advice. + - Impact: Incorrect AI responses, user frustration, wasted API calls on obsolete information. + +2. **No Quality Metrics or Monitoring**: Running curation pipelines without measuring quality or tracking trends means you don't know if context is improving or degrading. + - Example: Curating thousands of documents without tracking readability, freshness, or retrieval success rates. + - Impact: Silent quality degradation, no visibility into what's working, inability to optimize. + +3. **Ignoring Feedback Signals**: Not using AI response quality and user feedback to improve context curation misses opportunities for continuous improvement. + - Example: Users consistently rate AI responses as poor when using specific contexts, but those contexts are never reviewed or improved. + - Impact: Repeated failures, frustrated users, no learning from mistakes. + +4. **Over-Curation That Removes Useful Detail**: Being too aggressive with compression, summarization, or filtering can remove important nuances that AI needs for accurate responses. + - Example: Summarizing technical documentation so heavily that specific parameter names and usage examples are lost. + - Impact: AI responses lack necessary detail, users have to ask follow-up questions, increased API costs from multiple rounds. + +5. **No Deduplication Strategy**: Allowing redundant context to accumulate wastes tokens and can confuse AI with conflicting information. + - Example: Multiple versions of the same documentation chunk embedded with slight wording differences, all retrieved together. + - Impact: Wasted tokens, increased costs, potential for contradictory information in responses. + +6. **Missing Metadata for Provenance**: Not tracking where context came from, when it was curated, and what quality checks it passed makes debugging and improvement impossible. + - Example: AI gives incorrect information, but you can't trace which context chunk caused it or when it was added. + - Impact: Can't fix problems at the source, can't validate context quality, no audit trail. + +7. **Batch Processing Without Incremental Checkpoints**: Running long curation pipelines without checkpoints means interruptions lose all progress and have to restart from scratch. + - Example: Curating 10,000 documents in a 6-hour pipeline that fails at hour 5.

These frameworks ensure prompts, models, and agents perform consistently, safely, and effectively before deployment. + +## Why This Matters for AI-First Development + +AI systems introduce unique challenges that traditional software testing doesn't address. A prompt that works 90% of the time might fail catastrophically on the remaining 10%. A model that performs well in testing might degrade when deployed due to distribution shift. An agent that handles happy paths perfectly might spiral into expensive loops on edge cases. + +Traditional software has deterministic behavior: the same input always produces the same output. AI systems are probabilistic: outputs vary, quality fluctuates, and failure modes are often subtle. This fundamental difference demands evaluation frameworks specifically designed for AI: + +1. **Preventing silent degradation**: Without continuous evaluation, AI systems degrade invisibly as prompts drift, data distributions shift, or models update. Evaluation frameworks catch these regressions before they reach users, maintaining quality over time. + +2. **Enabling confident iteration**: Teams hesitate to improve prompts or agents without knowing whether changes help or hurt. Rigorous evaluation frameworks provide the confidence to iterate rapidly, measuring improvement objectively rather than relying on anecdotal evidence. + +3. **Balancing cost and quality**: AI systems often trade cost (tokens, latency, compute) for quality (accuracy, completeness, safety). Evaluation frameworks quantify these tradeoffs, enabling informed decisions about where to optimize and where premium performance justifies premium cost. + +Without evaluation frameworks, AI-first development becomes guesswork. Teams deploy prompts based on a few manual tests, discover failures in production, and struggle to identify root causes. Changes that seem to help might actually hurt on unseen inputs. Costs spiral as inefficient prompts waste tokens on every request. The system becomes fragile, expensive, and unreliableβ€”all problems that rigorous evaluation would prevent. + +## Implementation Approaches + +### 1. **Golden Dataset Evaluation** + +Create a curated dataset of inputs with expected outputs or quality scores. Run the AI system against this dataset regularly to track performance over time: + +```python +# Golden dataset with diverse test cases +golden_dataset = [ + { + "input": "Summarize this technical article about quantum computing...", + "expected_output": "A concise summary that captures key points without jargon", + "quality_criteria": ["accuracy", "conciseness", "clarity"], + "difficulty": "medium" + }, + { + "input": "Extract structured data from this receipt image", + "expected_output": {"total": 42.50, "date": "2024-01-15", "items": [...]}, + "quality_criteria": ["accuracy", "completeness"], + "difficulty": "hard" + } +] + +def evaluate_prompt_on_golden_dataset(prompt_template, model="claude-3-5-sonnet"): + """Evaluate prompt performance against golden dataset""" + results = [] + for test_case in golden_dataset: + # Generate response + response = llm_call(prompt_template.format(test_case["input"]), model) + + # Score quality + quality_score = score_response( + response, + test_case["expected_output"], + test_case["quality_criteria"] + ) + + results.append({ + "input": test_case["input"], + "response": response, + "score": quality_score, + "difficulty": test_case["difficulty"] + }) + + # Aggregate metrics + return { + "avg_score": mean([r["score"] for r in results]), + "score_by_difficulty": group_by(results, "difficulty"), + "failures": [r for r in results if r["score"] < 0.7] + } +``` + +**When to use**: Essential for all AI systems. Build this first before deploying any prompt or agent. Expand continuously as you discover new failure modes. + +**Success looks like**: Automated tests run on every prompt change, catching regressions before deployment. Team confidently iterates because metrics show clear improvement or degradation. + +### 2. **LLM-as-Judge Evaluation** + +Use a strong LLM to evaluate outputs from your production system, providing scalable assessment of quality dimensions that are hard to measure programmatically: + +```python +def llm_judge_evaluation(response, input_context, criteria): + """Use LLM to judge response quality on specific criteria""" + judge_prompt = f""" + Evaluate the following AI response based on these criteria: {criteria} + + INPUT: {input_context} + RESPONSE: {response} + + For each criterion, provide: + 1. Score (0-10) + 2. Brief justification + 3.

Essential for production systems with high quality requirements. + +**Success looks like**: Scalable evaluation of thousands of outputs without manual review. Quality scores correlate highly with human judgement (validate with human evaluators on a subset). + +### 3. **Regression Testing for Prompts** + +Track specific known failure cases and ensure fixes don't regress. Every discovered bug becomes a permanent test case: + +```python +class PromptRegressionTest: + """Test suite for tracking prompt regression cases""" + + def __init__(self, test_db_path="regression_tests.json"): + self.tests = load_json(test_db_path) + + def add_regression_test(self, name, input_text, issue_description, expected_behavior): + """Add a new regression test from a discovered failure""" + test_case = { + "name": name, + "input": input_text, + "issue": issue_description, + "expected": expected_behavior, + "added_date": datetime.now().isoformat(), + "status": "active" + } + self.tests.append(test_case) + save_json(self.test_db_path, self.tests) + + def run_regression_tests(self, prompt_fn): + """Run all regression tests against current prompt""" + results = [] + for test in self.tests: + if test["status"] != "active": + continue + + response = prompt_fn(test["input"]) + passed = check_behavior(response, test["expected"]) + + results.append({ + "name": test["name"], + "passed": passed, + "response": response, + "expected": test["expected"] + }) + + return { + "total": len(results), + "passed": sum(r["passed"] for r in results), + "failed": [r for r in results if not r["passed"]] + } + +# Example usage +regression_suite = PromptRegressionTest() + +# Add test when bug is discovered +regression_suite.add_regression_test( + name="special_chars_in_query", + input_text="Search for items with & and % characters", + issue_description="Bug #4271: Special characters caused search to crash", + expected_behavior="Returns search results without crashing" +) + +# Run tests on every prompt change +results = regression_suite.run_regression_tests(my_search_prompt) +if results["failed"]: + print(f"FAILED: {len(results['failed'])} regression tests failed!") + for failure in results["failed"]: + print(f" - {failure['name']}: {failure['issue']}") +``` + +**When to use**: Essential for production systems. Start collecting regression tests from day one. Every bug fix should include a regression test. + +**Success looks like**: Zero tolerance for reintroducing fixed bugs. Test suite grows with every discovered issue. Team confidently refactors prompts knowing regressions will be caught. + +### 4. **Property-Based Testing** + +Test that certain properties always hold across randomly generated inputs, discovering edge cases humans wouldn't think to test: + +```python +from hypothesis import given, strategies as st + +@given(st.text(min_size=1, max_size=1000)) +def test_summarization_always_shorter(input_text): + """Property: Summaries should always be shorter than input""" + summary = summarize_prompt(input_text) + assert len(summary) < len(input_text), f"Summary longer than input!" + +@given(st.lists(st.dictionaries(st.text(), st.integers()), min_size=1)) +def test_extraction_preserves_count(input_records): + """Property: Extraction should not lose records""" + extracted = extract_structured_data(input_records) + assert len(extracted) == len(input_records), "Lost records during extraction" + +@given(st.text()) +def test_translation_roundtrip_similarity(input_text): + """Property: Translate to French and back should be similar""" + french = translate_prompt(input_text, target="french") + back_to_english = translate_prompt(french, target="english") + similarity = semantic_similarity(input_text, back_to_english) + assert similarity > 0.7, "Roundtrip translation lost too much meaning" + +@given(st.integers(min_value=0, max_value=1000000)) +def test_number_extraction_accuracy(number): + """Property: Extracting numbers from text should be accurate""" + text = f"The total cost is ${number:,}" + extracted = extract_number_from_text(text) + assert extracted == number, f"Expected {number}, got {extracted}" + +# Run property-based tests +# Hypothesis will generate thousands of random inputs and verify properties hold +pytest.main([__file__, "-v"]) +``` + +**When to use**: For AI systems with clear invariants (summaries are shorter, extractions preserve structure, classifications return valid categories).

Requires sufficient traffic for statistical significance. + +**Success looks like**: Data-driven decisions about prompt changes. Clear evidence of improvement before full rollout. No surprises or regressions in production. + +### 6. **Human-in-the-Loop Validation** + +Incorporate human review at strategic checkpoints, focusing human effort on high-value, high-risk, or ambiguous cases: + +```python +class HumanValidationLoop: + """Framework for strategic human validation of AI outputs""" + + def __init__(self, confidence_threshold=0.8): + self.confidence_threshold = confidence_threshold + self.validation_queue = [] + self.human_feedback = [] + + def needs_human_validation(self, response, confidence_score): + """Determine if response needs human review""" + # Send to humans if: + # 1.

The bad example fixes bugs in code but doesn't prevent them from coming back, wasting time repeatedly fixing the same issues. + +### Example 3: Property-Based Edge Case Discovery + +**Good:** +```python +# property_tests.py - Systematic edge case discovery +from hypothesis import given, strategies as st + +class TranslationPropertyTests: + """Property-based tests discover edge cases automatically""" + + @given(st.text(min_size=1, max_size=500)) + def test_translation_preserves_meaning(self, text): + """Property: Translating and back should preserve meaning""" + french = translate(text, target="french") + back = translate(french, target="english") + similarity = semantic_similarity(text, back) + assert similarity > 0.7, f"Lost meaning: {text} -> {back}" + + @given(st.lists(st.text(min_size=1), min_size=1, max_size=10)) + def test_batch_translation_equals_individual(self, texts): + """Property: Batch translation should match individual""" + batch_results = translate_batch(texts, target="french") + individual_results = [translate(t, target="french") for t in texts] + assert batch_results == individual_results + + @given(st.text(alphabet=st.characters(blacklist_categories=['Cs', 'Cc']))) + def test_translation_handles_unicode(self, unicode_text): + """Property: Should handle any Unicode without crashing""" + try: + result = translate(unicode_text, target="french") + assert result is not None + except Exception as e: + pytest.fail(f"Crashed on Unicode input: {e}") + + @given(st.integers(min_value=0, max_value=1000)) + def test_translation_cost_linear(self, num_chars): + """Property: Cost should scale linearly with length""" + text = "a" * num_chars + tokens = count_tokens(translate(text, target="french")) + # Cost should be approximately linear (within 2x factor) + assert tokens < num_chars * 2 + +# Run property tests - Hypothesis generates thousands of inputs +pytest.main(["-v", "property_tests.py"]) + +# Example output: +# test_translation_preserves_meaning - Falsifying example: text='!@#$%^&*()' +# test_batch_translation_equals_individual - Passed 1000 examples +# test_translation_handles_unicode - Falsifying example: unicode_text='πŸ‘¨β€πŸ‘©β€πŸ‘§β€πŸ‘¦' +# test_translation_cost_linear - Passed 1000 examples +``` + +**Bad:** +```python +# bad_property_tests.py - Only tests cherry-picked examples +def test_translation(): + """Test a single example""" + result = translate("Hello world", target="french") + assert result == "Bonjour le monde" + +def test_translation_batch(): + """Test one batch example""" + results = translate_batch(["Hello", "Goodbye"], target="french") + assert len(results) == 2 + +# Missing edge cases: +# - Special characters +# - Unicode/emoji +# - Empty strings +# - Very long text +# - Numbers and punctuation +# - Mixed languages +``` + +**Why It Matters:** Property-based tests explore thousands of edge cases automatically, discovering failures humans wouldn't think to test. The good example found that special characters and emoji crashed the systemβ€”inputs that manual testing missed.

The good example calibrates against human judgments, corrects systematic bias, and requires evidence for scores. The bad example blindly trusts LLM scores without validation. + +### Example 5: A/B Testing with Statistical Rigor + +**Good:** +```python +# ab_testing_rigorous.py - Statistically rigorous A/B testing +class StatisticalABTest: + """A/B test with proper statistical analysis""" + + def __init__(self, control, treatment, min_sample_size=1000): + self.control = control + self.treatment = treatment + self.min_sample_size = min_sample_size + self.results = {"control": [], "treatment": []} + + def run_test(self, user_input, user_id): + """Run appropriate variant""" + variant = "treatment" if hash(user_id) % 2 == 0 else "control" + prompt = self.treatment if variant == "treatment" else self.control + + response = prompt(user_input) + self.results[variant].append({ + "user_id": user_id, + "response": response, + "timestamp": datetime.now() + }) + + return response + + def analyze_with_stats(self, metric_fn): + """Statistical analysis with confidence intervals""" + control_metrics = [metric_fn(r) for r in self.results["control"]] + treatment_metrics = [metric_fn(r) for r in self.results["treatment"]] + + # Check minimum sample size + if len(control_metrics) < self.min_sample_size: + return {"status": "insufficient_data", "needed": self.min_sample_size} + + # Calculate statistics + control_mean = mean(control_metrics) + treatment_mean = mean(treatment_metrics) + + # Statistical significance test + t_stat, p_value = ttest_ind(control_metrics, treatment_metrics) + + # Effect size (Cohen's d) + pooled_std = sqrt( + (stdev(control_metrics)**2 + stdev(treatment_metrics)**2) / 2 + ) + cohens_d = (treatment_mean - control_mean) / pooled_std + + # Confidence interval for lift + lift = ((treatment_mean - control_mean) / control_mean) * 100 + se_lift = sqrt( + (stdev(control_metrics)**2 / len(control_metrics)) + + (stdev(treatment_metrics)**2 / len(treatment_metrics)) + ) / control_mean * 100 + + ci_lower = lift - 1.96 * se_lift + ci_upper = lift + 1.96 * se_lift + + return { + "status": "complete", + "control_mean": control_mean, + "treatment_mean": treatment_mean, + "lift_pct": lift, + "confidence_interval_95": (ci_lower, ci_upper), + "p_value": p_value, + "significant": p_value < 0.05, + "effect_size": cohens_d, + "recommendation": self.generate_recommendation(p_value, lift, cohens_d) + } + + def generate_recommendation(self, p_value, lift, effect_size): + """Generate deployment recommendation""" + if p_value >= 0.05: + return "No significant difference - keep control" + elif lift > 0 and effect_size > 0.2: + return f"Deploy treatment - significant improvement ({lift:.1f}%)" + elif lift < 0 and abs(effect_size) > 0.2: + return f"Keep control - treatment significantly worse ({lift:.1f}%)" + else: + return "Difference too small to matter - keep control" + +# Example usage +ab_test = StatisticalABTest( + control=summarize_v1, + treatment=summarize_v2, + min_sample_size=1000 +) + +# Collect data from production +for request in production_stream: + ab_test.run_test(request.input, request.user_id) + + # Check if we can analyze yet + if len(ab_test.results["control"]) % 100 == 0: + analysis = ab_test.analyze_with_stats(user_satisfaction_score) + if analysis["status"] == "complete": + print(f"Results: {analysis['recommendation']}") + if analysis["significant"] and analysis["lift_pct"] > 5: + deploy_treatment() + break +``` + +**Bad:** +```python +# bad_ab_test.py - No statistical rigor +def ab_test_bad(control, treatment): + """Test with insufficient samples and no stats""" + # Run on 10 users (way too few!) + control_scores = [control(f"test_{i}") for i in range(5)] + treatment_scores = [treatment(f"test_{i}") for i in range(5)] + + # Simple average, no confidence interval, no significance test + if mean(treatment_scores) > mean(control_scores): + print("Treatment wins - deploying!") + deploy(treatment) + + # Issues: + # - Sample size too small (5 users) + # - No statistical significance test + # - No confidence intervals + # - No effect size measurement + # - No consideration of practical significance +``` + +**Why It Matters:** A/B tests without statistical rigor lead to false conclusions and wrong decisions.

Three months later, refactoring reintroduces the exact same bug. + - Impact: Wasted time repeatedly fixing the same issues. Loss of confidence in system stability. + +4. **Evaluation-Production Mismatch**: Testing on data that doesn't represent production distribution, leading to misleading quality metrics. + - Example: Testing medical diagnosis system on textbook cases, but production sees messy, ambiguous real-world reports. + - Impact: System that scores 95% in testing but only 60% in production because test data was too clean. + +5. **No Cost/Latency Tracking**: Optimizing only for quality without measuring cost and latency, resulting in expensive or slow systems. + - Example: Improving prompt accuracy from 90% to 92% by adding examples that triple token usage and double latency. + - Impact: Production system becomes too expensive or slow, negating quality improvements. Need to roll back changes. + +6. **Uncalibrated LLM-as-Judge**: Using LLM judgments without validating that they correlate with actual quality or human assessments. + - Example: LLM judge consistently rates all outputs 8-9/10, providing no signal about actual quality differences. + - Impact: False confidence in output quality. Unable to distinguish good from bad outputs. Evaluation becomes meaningless. + +7. **Manual Evaluation at Scale**: Relying on human review for all outputs instead of automating evaluation where possible. + - Example: Human reviewing every single response before deployment, creating bottleneck that prevents rapid iteration. + - Impact: Slow iteration cycles.

Like design patterns in software engineering, these patterns provide proven solutions to common prompting challenges, from simple instructions to complex multi-step reasoning. + +## Why This Matters for AI-First Development + +When AI agents build systems, they rely on prompts to communicate with LLMs at every levelβ€”generating code, analyzing requirements, debugging issues, and making architectural decisions. Without structured prompt patterns, these interactions become unpredictable, token-inefficient, and error-prone. A poorly structured prompt might cause an agent to generate buggy code, miss critical requirements, or consume excessive tokens retrying failed operations. + +Prompt design patterns provide three critical benefits for AI-driven development: + +1. **Predictable reasoning quality**: Structured patterns guide LLMs through complex reasoning tasks with consistent results. An agent using Chain-of-Thought patterns for code generation will show its reasoning steps, making errors easier to catch and correct. + +2. **Token efficiency**: Well-designed patterns maximize output quality per token spent. The power law relationship between prompt tokens and quality means finding the "maximum ROI zone" is criticalβ€”too few tokens yield poor results, too many hit diminishing returns or context rot. + +3. **Composable complexity**: Patterns can be combined to handle increasingly complex tasks. An agent might use ReAct (Reasoning + Acting) to debug a system, Tree-of-Thought to explore architectural options, and few-shot examples to generate implementation codeβ€”all working together systematically. + +Without these patterns, AI-first systems waste resources on trial-and-error prompting, produce inconsistent results across operations, and struggle with tasks requiring multi-step reasoning. An agent generating database migrations without prompt patterns might create syntax errors, miss edge cases, or fail to maintain idempotency. The same agent using established patterns produces reliable, well-reasoned code consistently. + +## Implementation Approaches + +### 1. **Zero-Shot Patterns (Atomic Prompts)** + +The simplest pattern: a single, clear instruction with constraints and output format. + +**Structure**: `[TASK] + [CONSTRAINTS] + [OUTPUT FORMAT]` + +```python +def zero_shot_prompt(task: str, constraints: list[str], format: str) -> str: + """Build a zero-shot prompt with clear structure.""" + prompt_parts = [ + f"Task: {task}", + "", + "Constraints:", + *[f"- {c}" for c in constraints], + "", + f"Output format: {format}" + ] + return "\n".join(prompt_parts) + +# Example usage +prompt = zero_shot_prompt( + task="Generate a Python function to validate email addresses", + constraints=[ + "Use regex for validation", + "Include type hints", + "Add docstring with examples", + "Handle edge cases (empty string, None)" + ], + format="Complete Python function with no placeholders" +) +``` + +**When to use**: Simple, well-defined tasks where the LLM has sufficient training data. Good for code generation, text transformation, and straightforward analysis. + +### 2. **Few-Shot Patterns (Examples as Context)** + +Provide 2-5 examples demonstrating the desired behavior before asking for new output. + +```python +def few_shot_prompt( + task: str, + examples: list[dict[str, str]], + new_input: str +) -> str: + """Build a few-shot prompt with examples.""" + prompt_parts = [f"Task: {task}", ""] + + for i, ex in enumerate(examples, 1): + prompt_parts.extend([ + f"Example {i}:", + f"Input: {ex['input']}", + f"Output: {ex['output']}", + "" + ]) + + prompt_parts.extend([ + "Now your turn:", + f"Input: {new_input}", + "Output:" + ]) + + return "\n".join(prompt_parts) + +# Example usage +prompt = few_shot_prompt( + task="Convert function names from snake_case to camelCase", + examples=[ + {"input": "get_user_data", "output": "getUserData"}, + {"input": "calculate_total_price", "output": "calculateTotalPrice"}, + {"input": "is_valid_email", "output": "isValidEmail"} + ], + new_input="create_database_connection" +) +``` + +**When to use**: Tasks requiring specific formatting, style matching, or domain-specific conventions. Essential when zero-shot produces inconsistent results. + +### 3. **Chain-of-Thought Patterns** + +Explicitly request step-by-step reasoning before the final answer. Dramatically improves accuracy on complex tasks. + +```python +def chain_of_thought_prompt(problem: str, zero_shot: bool = True) -> str: + """Build a chain-of-thought prompt for complex reasoning.""" + if zero_shot: + # Zero-shot CoT: just add "Let's think step by step" + return f"{problem}\n\nLet's think step by step:" + else: + # Few-shot CoT: include example reasoning + return f"""Solve this problem by breaking it down into steps. + +Example: +Problem: If a train travels 60 miles in 2 hours, what is its average speed? +Reasoning: +Step 1: Identify the formula: speed = distance / time +Step 2: Plug in values: speed = 60 miles / 2 hours +Step 3: Calculate: speed = 30 miles per hour +Answer: 30 mph + +Now solve this problem: +{problem} + +Reasoning:""" +``` + +**When to use**: Math problems, logical reasoning, code debugging, architectural decisionsβ€”anything requiring multi-step thinking. + +### 4. **ReAct Pattern (Reasoning + Acting)** + +Interleave reasoning traces with tool-using actions. The agent thinks, acts, observes, and adjusts iteratively. + +```python +def react_prompt_template(question: str, tools_available: list[str]) -> str: + """Build a ReAct prompt for agent operations.""" + return f"""Answer this question using available tools. + +Question: {question} + +Available tools: {', '.join(tools_available)} + +Use this format: +Thought: [your reasoning about what to do next] +Action: [tool to use with parameters] +Observation: [result from tool] +...

Perfect for debugging, system analysis, and research tasks. + +### 5. **Tree-of-Thought Pattern** + +Explore multiple reasoning paths in parallel, evaluate them, and choose the best solution. + +```python +def tree_of_thought_prompt(problem: str, num_paths: int = 3) -> str: + """Build a Tree-of-Thought prompt for exploration.""" + return f"""Solve this problem by exploring multiple approaches. + +Problem: {problem} + +Instructions: +1.

The bad example will produce inconsistent, incomplete results requiring multiple iterations and manual fixes. + +### Example 2: Debugging Complex Issue + +**Good:** +```python +# Using ReAct pattern for systematic debugging +prompt = """Debug why our payment processing service is timing out. + +Available tools: +- check_logs(service, time_range) +- check_metrics(metric_name, time_range) +- check_database_connections() +- run_query(sql) + +Use this format: +Thought: [reasoning about what to investigate] +Action: [tool to use] +Observation: [result] +... repeat as needed + +Question: Why are payments timing out after 2pm? + +Begin:""" +``` + +**Bad:** +```python +# Single-shot prompt without structure +prompt = "Why are payments timing out? Check the logs and tell me what's wrong." +``` + +**Why It Matters:** The ReAct pattern guides the agent through systematic investigation with explicit reasoning traces. The bad example expects the LLM to know what tools are available and how to use them, leading to hallucinated commands or incomplete analysis. + +### Example 3: Architecture Decision + +**Good:** +```python +# Using Tree-of-Thought for exploration +prompt = """Design a data retention strategy for user analytics events. + +Context: +- 100M events per day +- Legal requirement: keep 90 days +- Query patterns: 90% of queries are last 7 days +- Storage cost: $0.023 per GB-month + +Generate 3 different approaches: +1.

The good example forces comparison of multiple approaches with explicit criteria. The bad example produces a single solution without considering alternatives or trade-offs. + +### Example 4: API Response Formatting + +**Good:** +```python +# Using few-shot for consistent formatting +prompt = """Format API error responses according to our standard. + +Example 1: +Error: Invalid email format +Output: {"error": "validation_error", "message": "Invalid email format", "field": "email", "code": 400} + +Example 2: +Error: User not found +Output: {"error": "not_found", "message": "User not found", "resource": "user", "code": 404} + +Example 3: +Error: Rate limit exceeded +Output: {"error": "rate_limit", "message": "Rate limit exceeded", "retry_after": 60, "code": 429} + +Now format this error: +Error: Database connection timeout + +Output:""" +``` + +**Bad:** +```python +# Zero-shot without examples +prompt = "Format this error message in JSON: Database connection timeout" +``` + +**Why It Matters:** Few-shot learning ensures consistent structure across all error responses.

Use zero-shot for simple tasks, reserve advanced patterns for genuinely complex problems + +2. **Inconsistent Pattern Structure Within a System** + - Example: Some prompts use Chain-of-Thought with "Step 1, Step 2..." while others use "First, then, finally..." + - Impact: LLM has to adapt to different conventions, reducing reliability and making results harder to parse + - Avoid: Standardize on specific pattern templates across your system. Create reusable prompt-building functions + +3. **Forgetting to Specify Output Format** + - Example: "Analyze this code for security issues" without specifying JSON, markdown, or plain text format + - Impact: Unparseable outputs that require regex or brittle string manipulation to extract + - Avoid: Always include explicit output format in your pattern. "Output format: JSON with keys 'summary', 'issues', 'severity'" + +4. **Too Many Few-Shot Examples** + - Example: Providing 15 examples of error message formatting, consuming 2000 tokens + - Impact: Context window filled with examples instead of actual content, hitting the "diminishing returns" zone + - Avoid: 2-5 examples usually sufficient. More examples don't improve quality linearly but do consume tokens linearly + +5. **Missing Example Diversity in Few-Shot** + - Example: All few-shot examples show successful cases, none show edge cases or error handling + - Impact: LLM only learns happy-path behavior, fails on edge cases + - Avoid: Include diverse examples covering edge cases, error conditions, and boundary situations + +6. **Chain-of-Thought Without Validation** + - Example: Generating reasoning steps but not verifying the logic before using the conclusion + - Impact: LLMs can produce coherent-sounding but incorrect reasoning. Following bad reasoning leads to bad code + - Avoid: Parse and validate reasoning steps. Check that conclusions follow logically from premises + +7. **ReAct Pattern Without Proper Tool Descriptions** + - Example: "Available tools: search, analyze, fix" without describing parameters or return types + - Impact: LLM hallucinates tool parameters or misuses tools, causing errors + - Avoid: Provide complete tool signatures with parameter types and return value descriptions + +8. **Tree-of-Thought Without Evaluation Criteria** + - Example: "Generate 3 approaches" without specifying how to evaluate them + - Impact: All approaches rated equally, no basis for choosing one + - Avoid: Explicitly state evaluation criteria (cost, complexity, performance, maintainability) + +9. **Self-Consistency Without Aggregation Strategy** + - Example: Generating 5 different solutions but not specifying how to combine them + - Impact: Unclear which answer to trust when results conflict + - Avoid: Define aggregation method upfront (majority vote, weighted average, confidence-based selection) + +10. **Ignoring the Token-Quality Power Law** + - Example: Starting with minimal prompt, seeing poor quality, adding 5000 tokens of context + - Impact: Moving from "too few" directly to "diminishing returns" without finding the ROI sweet spot + - Avoid: Add tokens incrementally.

Like packing a suitcase with weight limits, every token countsβ€”what you include, what you leave out, and how you arrange it all determines whether the model can perform the task successfully. + +## Why This Matters for AI-First Development + +AI models have finite context windowsβ€”typically 8K to 200K tokensβ€”and every token consumes computational resources, adds latency, and increases cost. When AI agents build and modify systems autonomously, inefficient context management creates compounding problems: wasted API costs, slower responses, incomplete information reaching the model, and degraded performance as irrelevant information dilutes critical context. + +Context window management becomes critical for AI-first development in three key ways: + +1. **Cost scaling**: As AI agents make thousands of API calls during development cycles, token waste multiplies rapidly. A 100K token context that could be 20K tokens means 5x higher costs across every operationβ€”testing, debugging, code generation, and validation. + +2. **Information density**: Models perform better when context is information-dense rather than information-dilute. Filling the context window with irrelevant examples, redundant instructions, or verbose documentation reduces the model's ability to focus on what matters. Quality over quantity determines success. + +3. **Cognitive load management**: Just as humans struggle with information overload, models become less precise when context windows contain competing signals, contradictory examples, or excessive noise. Strategic curation prevents degradation. + +Without proper context window management, AI-driven systems waste resources on every operation, perform worse despite using more tokens, and create invisible technical debt through inefficient patterns that compound over time. A poorly managed 100K context might deliver worse results than a well-curated 10K context at 10x the cost. + +## Implementation Approaches + +### 1. **Progressive Context Loading** + +Load information incrementally as needed rather than front-loading the entire context window: + +```python +class ProgressiveContextManager: + def __init__(self, model_max_tokens: int = 100_000): + self.max_tokens = model_max_tokens + self.current_tokens = 0 + self.context_layers = [] + + def add_layer(self, content: str, priority: int, token_count: int) -> bool: + """Add context layer if budget allows, ordered by priority.""" + if self.current_tokens + token_count > self.max_tokens: + return False + + self.context_layers.append({ + "content": content, + "priority": priority, + "tokens": token_count + }) + self.current_tokens += token_count + return True + + def build_context(self) -> str: + """Assemble context from highest to lowest priority.""" + # Sort by priority (highest first) + sorted_layers = sorted( + self.context_layers, + key=lambda x: x["priority"], + reverse=True + ) + return "\n\n".join([layer["content"] for layer in sorted_layers]) + +# Usage +context = ProgressiveContextManager(max_tokens=8000) +context.add_layer(system_prompt, priority=10, token_count=200) +context.add_layer(critical_examples, priority=9, token_count=1500) +context.add_layer(documentation, priority=5, token_count=3000) +# Optional layers only if budget permits +context.add_layer(edge_cases, priority=3, token_count=2000) +``` + +When to use: Complex tasks requiring multiple types of information where not everything fits. Start with essentials, add optional context only if space permits. + +### 2. **Semantic Chunking with Context Preservation** + +Break large documents into meaningful chunks while preserving context about what each chunk represents: + +```python +def create_contextual_chunks( + document: str, + chunk_size: int = 800, + context_instruction: str = None +) -> list[dict]: + """ + Chunk document while adding explanatory context to each chunk. + Based on Anthropic's Contextual Retrieval technique. + """ + chunks = split_document(document, chunk_size) + contextualized_chunks = [] + + for chunk in chunks: + # Use Claude to generate chunk-specific context + context_prompt = f""" + + {document} + + + Here is the chunk we want to situate within the whole document: + + {chunk} + + + Please give a short succinct context (50-100 tokens) to situate + this chunk within the overall document for improving search retrieval. + Answer only with the succinct context and nothing else. + """ + + chunk_context = call_model(context_prompt) + + contextualized_chunks.append({ + "original": chunk, + "contextualized": f"{chunk_context}\n\n{chunk}", + "context_only": chunk_context + }) + + return contextualized_chunks +``` + +When to use: RAG systems, knowledge bases, or any scenario requiring document chunking. Prevents information loss that traditional chunking causes. + +### 3. **Dynamic Example Selection** + +Select the most relevant examples for each specific query rather than using static few-shot examples: + +```python +def select_relevant_examples( + query: str, + example_bank: list[dict], + max_examples: int = 3, + max_tokens: int = 2000 +) -> list[dict]: + """ + Dynamically select most relevant examples based on query similarity. + """ + from sklearn.metrics.pairwise import cosine_similarity + + # Embed query and all examples + query_embedding = embed(query) + example_embeddings = [embed(ex["input"]) for ex in example_bank] + + # Calculate similarity scores + similarities = cosine_similarity( + [query_embedding], + example_embeddings + )[0] + + # Rank examples by similarity + ranked_indices = similarities.argsort()[::-1] + + # Select top examples within token budget + selected = [] + current_tokens = 0 + + for idx in ranked_indices: + example = example_bank[idx] + example_tokens = count_tokens(example["input"] + example["output"]) + + if len(selected) >= max_examples: + break + if current_tokens + example_tokens > max_tokens: + break + + selected.append(example) + current_tokens += example_tokens + + return selected + +# Usage +query = "Calculate revenue growth for Q2 2023" +relevant_examples = select_relevant_examples( + query, + all_examples, + max_examples=3, + max_tokens=2000 +) +``` + +When to use: Few-shot learning scenarios where you have many examples but limited context budget. Maximizes example relevance while respecting token constraints. + +### 4. **Context Pruning and Compression** + +Remove redundant or low-value information before sending context: + +```python +def prune_context( + context: str, + target_tokens: int, + strategy: str = "importance" +) -> str: + """ + Reduce context size while preserving most important information. + """ + if count_tokens(context) <= target_tokens: + return context + + if strategy == "importance": + # Use extractive summarization to keep important sentences + sentences = split_into_sentences(context) + sentence_scores = score_sentence_importance(sentences, context) + + # Sort by importance, select until token budget reached + ranked = sorted( + zip(sentences, sentence_scores), + key=lambda x: x[1], + reverse=True + ) + + pruned = [] + current_tokens = 0 + for sent, score in ranked: + sent_tokens = count_tokens(sent) + if current_tokens + sent_tokens > target_tokens: + break + pruned.append(sent) + current_tokens += sent_tokens + + # Maintain original order + pruned_ordered = [s for s in sentences if s in pruned] + return " ".join(pruned_ordered) + + elif strategy == "summarization": + # Use LLM to compress while preserving key information + summary_prompt = f""" + Compress the following text to approximately {target_tokens} tokens + while preserving all critical information: + + {context} + """ + return call_model(summary_prompt) + +# Usage +large_context = load_documentation() # 50K tokens +compressed = prune_context(large_context, target_tokens=10_000, strategy="importance") +``` + +When to use: Documentation, retrieved passages, or historical context that exceeds budget. Balance information preservation with token efficiency. + +### 5. **Layered Context Architecture** + +Organize context into priority tiers, including only higher tiers when budget is constrained: + +```python +class LayeredContext: + """ + Organize context into priority layers for flexible budget allocation. + """ + def __init__(self): + self.layers = { + "system": [], # Priority 1: Always include + "critical": [], # Priority 2: Core task information + "supporting": [], # Priority 3: Helpful but not essential + "optional": [] # Priority 4: Nice to have + } + + def add(self, layer: str, content: str): + """Add content to a specific layer.""" + if layer not in self.layers: + raise ValueError(f"Unknown layer: {layer}") + self.layers[layer].append(content) + + def build(self, max_tokens: int) -> str: + """Build context respecting token budget.""" + context_parts = [] + remaining_tokens = max_tokens + + # Process layers in priority order + for layer_name in ["system", "critical", "supporting", "optional"]: + layer_content = "\n\n".join(self.layers[layer_name]) + layer_tokens = count_tokens(layer_content) + + if layer_tokens <= remaining_tokens: + context_parts.append(layer_content) + remaining_tokens -= layer_tokens + else: + # Include what fits from this layer + truncated = truncate_to_tokens(layer_content, remaining_tokens) + if truncated: + context_parts.append(truncated) + break + + return "\n\n".join(context_parts) + +# Usage +context = LayeredContext() +context.add("system", "You are a Python code analyzer...") +context.add("critical", "Analyze this function: def process()...") +context.add("supporting", "Coding standards: PEP 8...") +context.add("optional", "Historical context: Previous versions...") + +final_context = context.build(max_tokens=4000) +``` + +When to use: Multi-faceted tasks where different types of information have clear priority hierarchies. Ensures essential information never gets crowded out. + +### 6. **Token Budget Allocation** + +Explicitly allocate token budgets across different context components: + +```python +class TokenBudgetManager: + """ + Manage token allocation across context components. + """ + def __init__(self, total_budget: int): + self.total_budget = total_budget + self.allocations = {} + self.used = {} + + def allocate(self, component: str, tokens: int): + """Reserve tokens for a component.""" + if sum(self.allocations.values()) + tokens > self.total_budget: + raise ValueError(f"Budget exceeded: {component} needs {tokens}") + self.allocations[component] = tokens + self.used[component] = 0 + + def use(self, component: str, content: str) -> bool: + """Mark tokens as used for a component.""" + token_count = count_tokens(content) + if token_count > self.allocations[component]: + return False + self.used[component] = token_count + return True + + def get_remaining(self, component: str) -> int: + """Get remaining tokens for a component.""" + return self.allocations[component] - self.used[component] + + def summary(self) -> dict: + """Get budget utilization summary.""" + return { + "total_budget": self.total_budget, + "allocated": sum(self.allocations.values()), + "used": sum(self.used.values()), + "remaining": self.total_budget - sum(self.used.values()), + "per_component": { + comp: { + "allocated": self.allocations[comp], + "used": self.used[comp], + "remaining": self.allocations[comp] - self.used[comp] + } + for comp in self.allocations + } + } + +# Usage +budget = TokenBudgetManager(total_budget=8000) +budget.allocate("system_prompt", 500) +budget.allocate("examples", 2000) +budget.allocate("documentation", 3000) +budget.allocate("query", 500) +budget.allocate("buffer", 2000) # Reserved for response +``` + +When to use: Complex applications where multiple context types compete for limited space. Prevents any single component from monopolizing the context window. + +## Good Examples vs Bad Examples + +### Example 1: Few-Shot Learning Efficiency + +**Good:** +```python +def build_few_shot_context( + task_description: str, + examples: list[dict], + query: str, + max_examples: int = 3 +) -> str: + """ + Efficient few-shot context with diminishing returns awareness. + Research shows 2-4 examples often optimal; more = diminishing returns. + """ + # Select most diverse/relevant examples + selected = select_diverse_examples(examples, max_count=max_examples) + + context = f"{task_description}\n\n" + + for i, ex in enumerate(selected, 1): + context += f"Example {i}:\n" + context += f"Input: {ex['input']}\n" + context += f"Output: {ex['output']}\n\n" + + context += f"Now your turn:\nInput: {query}\nOutput:" + + return context # ~1500 tokens, optimal performance/cost ratio +``` + +**Bad:** +```python +def build_few_shot_context( + task_description: str, + examples: list[dict], + query: str +) -> str: + """ + Wasteful: includes all examples regardless of value. + """ + context = f"{task_description}\n\n" + + # Include ALL examples (might be 20-50!) + for i, ex in enumerate(examples, 1): + context += f"Example {i}:\n" + context += f"Input: {ex['input']}\n" + context += f"Output: {ex['output']}\n\n" + + context += f"Now your turn:\nInput: {query}\nOutput:" + + return context # ~15K tokens, minimal benefit over 3-5 examples +``` + +**Why It Matters:** Research shows few-shot learning exhibits diminishing returnsβ€”each additional example beyond 3-5 provides less benefit while consuming more tokens. The bad example wastes ~13.5K tokens for marginal (often zero) improvement, multiplying costs 10x with no performance gain. + +### Example 2: Documentation Retrieval + +**Good:** +```python +def retrieve_relevant_docs( + query: str, + doc_database: list[dict], + max_tokens: int = 3000 +) -> str: + """ + Retrieve and rank documentation, include only what fits. + """ + # Semantic search for relevant docs + ranked_docs = search_docs(query, doc_database, top_k=20) + + # Rerank for precision + reranked = rerank_docs(query, ranked_docs, top_k=10) + + # Include docs until token budget exhausted + selected_docs = [] + current_tokens = 0 + + for doc in reranked: + doc_tokens = count_tokens(doc["content"]) + if current_tokens + doc_tokens > max_tokens: + # Try to include partial content + remaining = max_tokens - current_tokens + if remaining > 200: # Minimum useful chunk + selected_docs.append(truncate_to_tokens(doc["content"], remaining)) + break + + selected_docs.append(doc["content"]) + current_tokens += doc_tokens + + return "\n\n---\n\n".join(selected_docs) +``` + +**Bad:** +```python +def retrieve_relevant_docs( + query: str, + doc_database: list[dict] +) -> str: + """ + Naive: dumps all potentially relevant docs without ranking or limiting. + """ + # Search for relevant docs (no ranking) + relevant_docs = search_docs(query, doc_database, top_k=50) + + # Include everything + all_docs = [doc["content"] for doc in relevant_docs] + + return "\n\n---\n\n".join(all_docs) # Might be 50K+ tokens! +``` + +**Why It Matters:** The bad example might include 50 documents totaling 50K+ tokens, overwhelming the context window and diluting the truly relevant information. The good example uses semantic search + reranking + budget constraints to deliver dense, relevant context within 3K tokensβ€”better results at a fraction of the cost. + +### Example 3: Conversation History Management + +**Good:** +```python +class ConversationManager: + """ + Smart conversation history with automatic pruning. + """ + def __init__(self, max_history_tokens: int = 4000): + self.messages = [] + self.max_tokens = max_history_tokens + + def add_message(self, role: str, content: str): + """Add message and prune if needed.""" + self.messages.append({"role": role, "content": content}) + self._prune_if_needed() + + def _prune_if_needed(self): + """Keep recent messages within token budget.""" + total_tokens = sum(count_tokens(m["content"]) for m in self.messages) + + if total_tokens <= self.max_tokens: + return + + # Keep system message + recent conversation + system_msgs = [m for m in self.messages if m["role"] == "system"] + conversation = [m for m in self.messages if m["role"] != "system"] + + # Remove oldest conversation messages until within budget + while total_tokens > self.max_tokens and len(conversation) > 2: + removed = conversation.pop(0) + total_tokens -= count_tokens(removed["content"]) + + self.messages = system_msgs + conversation + + def get_context(self) -> list[dict]: + """Return current conversation context.""" + return self.messages +``` + +**Bad:** +```python +class ConversationManager: + """ + Keeps entire conversation history indefinitely. + """ + def __init__(self): + self.messages = [] + + def add_message(self, role: str, content: str): + """Just append, never prune.""" + self.messages.append({"role": role, "content": content}) + + def get_context(self) -> list[dict]: + """Return ALL history, no matter how long.""" + return self.messages # Grows unbounded! +``` + +**Why It Matters:** Long conversations can easily exceed context windows. The bad example eventually crashes (when history exceeds max tokens) or wastes massive amounts of tokens on ancient history. The good example maintains relevant recent context within budget, ensuring consistent performance and costs. + +### Example 4: Code Context for AI Coding Assistants + +**Good:** +```python +def build_code_context( + target_file: str, + query: str, + codebase_root: str, + max_tokens: int = 10_000 +) -> str: + """ + Strategic code context: target file + relevant dependencies. + """ + context_parts = [] + budget = TokenBudgetManager(max_tokens) + + # Allocate budget strategically + budget.allocate("target_file", 3000) + budget.allocate("direct_imports", 4000) + budget.allocate("related_files", 2000) + budget.allocate("buffer", 1000) + + # Target file (always include) + target_code = read_file(target_file) + target_truncated = truncate_to_tokens(target_code, 3000) + context_parts.append(f"# Target file: {target_file}\n{target_truncated}") + + # Direct imports (high priority) + imports = extract_imports(target_code) + for imp in imports[:5]: # Limit to top 5 imports + import_code = read_file(find_import_file(imp, codebase_root)) + import_truncated = truncate_to_tokens(import_code, 800) + context_parts.append(f"# Import: {imp}\n{import_truncated}") + + # Related files (if budget permits) + related = find_related_files(target_file, query, codebase_root) + remaining = budget.get_remaining("related_files") + for rel in related: + rel_code = read_file(rel) + rel_tokens = min(count_tokens(rel_code), remaining // len(related)) + rel_truncated = truncate_to_tokens(rel_code, rel_tokens) + context_parts.append(f"# Related: {rel}\n{rel_truncated}") + + return "\n\n".join(context_parts) +``` + +**Bad:** +```python +def build_code_context( + target_file: str, + query: str, + codebase_root: str +) -> str: + """ + Naive: dump entire files without budget management. + """ + context_parts = [] + + # Include target file (might be huge) + target_code = read_file(target_file) + context_parts.append(f"# Target file: {target_file}\n{target_code}") + + # Include ALL imports (might be dozens) + imports = extract_imports(target_code) + for imp in imports: + import_code = read_file(find_import_file(imp, codebase_root)) + context_parts.append(f"# Import: {imp}\n{import_code}") + + # Include ALL related files + related = find_related_files(target_file, query, codebase_root) + for rel in related: + rel_code = read_file(rel) + context_parts.append(f"# Related: {rel}\n{rel_code}") + + return "\n\n".join(context_parts) # Might be 100K+ tokens! +``` + +**Why It Matters:** Code files can be enormous, and codebases have complex dependency graphs. The bad example might include 50+ files totaling 100K+ tokens, exceeding most context windows and causing API errors. The good example provides strategic snippets from key files, respecting token budgets while maintaining sufficient context for the task. + +### Example 5: Batch Processing with Context Reuse + +**Good:** +```python +def process_batch_with_caching( + items: list[str], + shared_context: str, + instruction_template: str +) -> list[str]: + """ + Use prompt caching for shared context across batch. + Anthropic's prompt caching reduces costs by 90% for repeated context. + """ + results = [] + + # Mark shared context for caching + cached_prompt = { + "system": [ + { + "type": "text", + "text": shared_context, + "cache_control": {"type": "ephemeral"} + } + ] + } + + # Process items reusing cached context + for item in items: + prompt = instruction_template.format(item=item) + + response = call_model_with_cache( + system=cached_prompt["system"], + messages=[{"role": "user", "content": prompt}] + ) + + results.append(response) + + return results + # First call: Full cost for shared_context + # Subsequent calls: 90% discount on shared_context +``` + +**Bad:** +```python +def process_batch_naive( + items: list[str], + shared_context: str, + instruction_template: str +) -> list[str]: + """ + Naive: repeats full context for every item. + """ + results = [] + + for item in items: + # Build full prompt from scratch every time + full_prompt = f"{shared_context}\n\n{instruction_template.format(item=item)}" + + response = call_model(full_prompt) + results.append(response) + + return results + # Every call: Full cost for entire context + # 100 items = 100x the context cost! +``` + +**Why It Matters:** When processing 100 items with 10K tokens of shared context, the bad example processes 1M tokens of redundant context. The good example caches the shared context, processing just 10K + (100 * query_tokens). For a 10K shared context and 100-token queries, that's 1M tokens vs. 20K tokensβ€”a 50x cost reduction with identical results. + +## Related Principles + +- **[Principle #14 - Context-Aware Agent Prompting](../process/14-context-aware-agent-prompting.md)** - Context window management enables context-aware prompting by ensuring the right information reaches the model within budget constraints.

It's the practice of showing the model 2-5 high-quality examples that establish patterns, formats, and expectations, enabling the model to generalize to new inputs. + +## Why This Matters for AI-First Development + +When AI agents generate code, analyze systems, or automate workflows, they need clear patterns to follow. Few-shot examples act as executable specificationsβ€”they show not just what to do, but how to do it. Unlike traditional documentation that describes behavior in prose, few-shot examples demonstrate actual input-output patterns that models can directly replicate and adapt. + +Few-shot learning architecture provides three critical benefits for AI-driven development: + +1. **Precision through demonstration**: A single well-crafted example often communicates requirements more clearly than paragraphs of description. AI agents can see exact formatting, error handling patterns, edge case behavior, and output structure in concrete form rather than inferring from abstract instructions. + +2. **Consistency across operations**: When multiple AI agents or operations need to produce similar outputs, few-shot examples establish a shared template. This ensures API responses follow the same structure, code follows the same patterns, and error messages use consistent formatsβ€”without explicit rules for every decision. + +3. **Reduced hallucination and drift**: Models are more likely to stay grounded when they have concrete examples to anchor their responses. Few-shot examples constrain the solution space, reducing the likelihood of the model inventing non-existent APIs, fabricating data structures, or drifting into off-topic responses. + +Without thoughtful few-shot architecture, AI systems become unpredictable. An agent might generate code in wildly different styles depending on minor prompt variations. It might invent plausible-sounding but incorrect API patterns. It might struggle with edge cases because it never saw examples of how to handle them. These failures compound in AI-first systems where one agent's output becomes another agent's inputβ€”poor example selection early in a pipeline cascades into system-wide inconsistency. + +## Implementation Approaches + +### 1. **Static Example Banks** + +Create curated collections of high-quality examples organized by task type, complexity, and domain. Store these in version-controlled repositories where they can be tested, reviewed, and evolved. + +When to use: For stable, well-understood tasks where the pattern doesn't change frequently (API response formats, code style conventions, data transformation patterns). + +```python +EXAMPLE_BANK = { + "error_handling": [ + { + "input": "Division by zero in calculate_average", + "output": { + "error": "ValidationError", + "message": "Cannot calculate average: denominator is zero", + "suggestion": "Ensure input array is non-empty before calling calculate_average" + } + }, + { + "input": "Null pointer in database connection", + "output": { + "error": "ConnectionError", + "message": "Database connection is null", + "suggestion": "Verify database service is running and credentials are correct" + } + } + ], + "api_response": [ + { + "input": "User registration successful", + "output": { + "status": "success", + "data": {"user_id": "usr_abc123", "email": "user@example.com"}, + "meta": {"timestamp": "2025-09-30T10:00:00Z"} + } + } + ] +} + +def get_examples(task_type: str, count: int = 3) -> list[dict]: + """Retrieve examples from the bank for a given task type.""" + return EXAMPLE_BANK.get(task_type, [])[:count] +``` + +### 2. **Dynamic Example Selection** + +Select examples at runtime based on similarity to the current input. Use embeddings or keyword matching to find the most relevant demonstrations from a larger pool. + +When to use: When inputs vary significantly and generic examples don't capture the diversity of cases (domain-specific code generation, natural language tasks with wide vocabulary, context-dependent formatting). + +```python +from sentence_transformers import SentenceTransformer +import numpy as np + +class DynamicExampleSelector: + def __init__(self, example_pool: list[dict]): + self.example_pool = example_pool + self.model = SentenceTransformer('all-MiniLM-L6-v2') + self.example_embeddings = self.model.encode( + [ex["input"] for ex in example_pool] + ) + + def select_examples(self, query: str, k: int = 3) -> list[dict]: + """Select k most similar examples to the query.""" + query_embedding = self.model.encode([query])[0] + similarities = np.dot(self.example_embeddings, query_embedding) + top_k_indices = np.argsort(similarities)[-k:][::-1] + return [self.example_pool[i] for i in top_k_indices] +``` + +### 3. **Stratified Example Coverage** + +Ensure examples cover the full range of complexity, edge cases, and variations. Include simple cases, complex cases, error cases, and boundary conditions. + +When to use: For tasks where edge cases are critical and the model needs to handle diverse scenarios (data validation, security-sensitive operations, multi-step workflows). + +```python +def build_stratified_examples(domain: str) -> list[dict]: + """Build examples that cover complexity spectrum.""" + return [ + # Simple baseline + {"complexity": "simple", "input": "2 + 2", "output": "4"}, + + # Standard case + {"complexity": "standard", "input": "(5 * 3) + 2", "output": "17"}, + + # Edge case: division by zero + {"complexity": "edge", "input": "10 / 0", + "output": "Error: Division by zero"}, + + # Complex nested expression + {"complexity": "complex", "input": "((2 + 3) * (4 - 1)) / (6 + 2)", + "output": "1.875"}, + + # Boundary: very large numbers + {"complexity": "boundary", "input": "999999 * 999999", + "output": "999998000001"} + ] +``` + +### 4. **Chain-of-Thought Examples** + +Structure examples to expose reasoning steps, not just input-output pairs. Show intermediate calculations, decision points, and the path to the final answer. + +When to use: For complex tasks requiring multi-step reasoning (debugging, optimization, design decisions, mathematical problem-solving). + +```python +COT_EXAMPLES = [ + { + "input": "Find the bug in this code: `for i in range(len(arr)): arr[i+1] = arr[i] * 2`", + "thinking": [ + "1. Loop iterates from i=0 to i=len(arr)-1", + "2. Inside loop, accessing arr[i+1] which goes up to arr[len(arr)]", + "3. This causes IndexError when i = len(arr)-1", + "4. Should be arr[i] = arr[i] * 2, not arr[i+1]" + ], + "output": "Bug: Array index out of bounds. Change arr[i+1] to arr[i]." + } +] +``` + +### 5. **Format-First Example Design** + +Create examples that establish formatting conventions first, then vary the content. This teaches models the structure before introducing complexity. + +When to use: For structured output generation (JSON APIs, configuration files, code templates, documentation). + +```python +FORMAT_EXAMPLES = [ + { + "description": "User authentication endpoint", + "example": { + "endpoint": "/api/v1/auth/login", + "method": "POST", + "request": {"email": "user@example.com", "password": "***"}, + "response": {"token": "jwt_token_here", "expires_in": 3600} + } + }, + { + "description": "User profile retrieval endpoint", + "example": { + "endpoint": "/api/v1/users/{id}", + "method": "GET", + "request": None, + "response": {"id": "usr_123", "name": "John Doe", "email": "john@example.com"} + } + } +] +``` + +### 6. **Adaptive Example Pruning** + +Start with a rich set of examples, then remove those that don't improve performance. Measure which examples contribute to accuracy and which add token cost without benefit. + +When to use: When optimizing for cost and latency after establishing baseline accuracy (production optimization, high-volume operations, cost-sensitive applications). + +```python +def evaluate_example_contribution( + task: str, + example_set: list[dict], + test_cases: list[dict] +) -> dict[int, float]: + """Measure each example's contribution to accuracy.""" + contributions = {} + + for i in range(len(example_set)): + # Test with all examples except i + reduced_set = example_set[:i] + example_set[i+1:] + accuracy = measure_accuracy(task, reduced_set, test_cases) + contributions[i] = accuracy + + return contributions + +def prune_examples(examples: list[dict], contributions: dict[int, float], + baseline_accuracy: float, threshold: float = 0.95) -> list[dict]: + """Remove examples that don't significantly impact accuracy.""" + return [ + ex for i, ex in enumerate(examples) + if contributions[i] >= baseline_accuracy * threshold + ] +``` + +## Good Examples vs Bad Examples + +### Example 1: Code Generation Task + +**Good:** +```python +# Few-shot examples showing style, error handling, and docstrings +EXAMPLES = [ + { + "task": "Write a function to validate email", + "code": '''def validate_email(email: str) -> bool: + """Validate email format using regex. + + Args: + email: Email address to validate + + Returns: + True if email is valid, False otherwise + """ + import re + pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$' + return bool(re.match(pattern, email))''' + }, + { + "task": "Write a function to parse JSON safely", + "code": '''def parse_json(json_string: str) -> dict | None: + """Parse JSON string with error handling. + + Args: + json_string: JSON-formatted string + + Returns: + Parsed dictionary or None if parsing fails + """ + import json + try: + return json.loads(json_string) + except json.JSONDecodeError as e: + print(f"JSON parsing error: {e}") + return None''' + } +] +``` + +**Bad:** +```python +# Examples that don't establish clear patterns +EXAMPLES = [ + { + "task": "Write a function", + "code": "def func(x): return x * 2" # No docstring, unclear purpose + }, + { + "task": "Another function", + "code": """ + def process(data): + # TODO: implement this + pass + """ # Incomplete example + } +] +``` + +**Why It Matters:** Good examples establish conventions for documentation, type hints, error handling, and code organization. Bad examples teach inconsistent patternsβ€”the model learns that sometimes you document, sometimes you don't, leading to unpredictable output quality. + +### Example 2: API Response Formatting + +**Good:** +```python +# Consistent response structure across different scenarios +RESPONSE_EXAMPLES = [ + { + "scenario": "Success with data", + "response": { + "status": "success", + "data": {"user_id": "usr_123", "name": "Alice"}, + "meta": {"timestamp": "2025-09-30T10:00:00Z", "version": "1.0"} + } + }, + { + "scenario": "Error with details", + "response": { + "status": "error", + "error": { + "code": "VALIDATION_ERROR", + "message": "Email address is invalid", + "field": "email" + }, + "meta": {"timestamp": "2025-09-30T10:00:01Z", "version": "1.0"} + } + }, + { + "scenario": "Success with pagination", + "response": { + "status": "success", + "data": [{"id": 1, "name": "Item 1"}, {"id": 2, "name": "Item 2"}], + "pagination": {"page": 1, "total_pages": 10, "total_items": 95}, + "meta": {"timestamp": "2025-09-30T10:00:02Z", "version": "1.0"} + } + } +] +``` + +**Bad:** +```python +# Inconsistent response structures +RESPONSE_EXAMPLES = [ + {"user": {"id": "usr_123"}}, # No status or meta + {"status": "ok", "result": {"id": 456}}, # Different key names + {"error": "Invalid input"}, # No structure, just string +] +``` + +**Why It Matters:** Consistent response structures allow client code to reliably parse responses. Inconsistent examples teach the model that anything goes, resulting in unpredictable API behavior that breaks client integrations. + +### Example 3: Example Selection Strategy + +**Good:** +```python +def select_diverse_examples(query: str, pool: list[dict], k: int = 3) -> list[dict]: + """Select examples that cover different aspects of the task.""" + # Get most similar example + most_similar = find_most_similar(query, pool) + + # Get examples covering edge cases + edge_cases = [ex for ex in pool if ex.get("is_edge_case", False)] + + # Get example with error handling + error_example = next((ex for ex in pool if "error" in ex["output"]), None) + + # Combine for diversity + selected = [most_similar] + if edge_cases: + selected.append(edge_cases[0]) + if error_example and error_example not in selected: + selected.append(error_example) + + return selected[:k] +``` + +**Bad:** +```python +def select_examples(query: str, pool: list[dict], k: int = 3) -> list[dict]: + """Just return the first k examples.""" + return pool[:k] # Always returns same examples regardless of query +``` + +**Why It Matters:** Dynamic selection based on query similarity and diversity improves model performance by providing relevant demonstrations. Static selection wastes context window on irrelevant examples and may miss critical patterns the query needs. + +### Example 4: Token Budget Management + +**Good:** +```python +def build_efficient_prompt( + instruction: str, + examples: list[dict], + query: str, + max_tokens: int = 4000 +) -> str: + """Build prompt that fits within token budget.""" + import tiktoken + + enc = tiktoken.get_encoding("cl100k_base") + + # Reserve tokens for instruction and query + instruction_tokens = len(enc.encode(instruction)) + query_tokens = len(enc.encode(query)) + available_for_examples = max_tokens - instruction_tokens - query_tokens - 500 # Buffer + + # Add examples until budget exhausted + prompt_parts = [instruction] + examples_used = 0 + + for example in examples: + example_str = format_example(example) + example_tokens = len(enc.encode(example_str)) + + if example_tokens <= available_for_examples: + prompt_parts.append(example_str) + available_for_examples -= example_tokens + examples_used += 1 + else: + break + + prompt_parts.append(f"Now solve: {query}") + return "\n\n".join(prompt_parts) +``` + +**Bad:** +```python +def build_prompt(instruction: str, examples: list[dict], query: str) -> str: + """Build prompt with all examples regardless of token count.""" + prompt = instruction + "\n\n" + + # Include all examples even if they exceed context window + for ex in examples: + prompt += format_example(ex) + "\n\n" + + prompt += f"Now solve: {query}" + return prompt +``` + +**Why It Matters:** Context windows have hard limits. Naively including all examples can exceed limits, causing truncation or errors. Token-aware prompt building ensures the most valuable examples fit within the budget, maintaining quality while respecting constraints. + +### Example 5: Chain-of-Thought Formatting + +**Good:** +```python +COT_EXAMPLES = [ + { + "input": "Optimize query: SELECT * FROM users WHERE active = 1 AND created_at > '2025-01-01'", + "thinking": [ + "Step 1: Analyze current query structure", + "- Full table scan on 'users' table", + "- Two WHERE conditions (active and created_at)", + "", + "Step 2: Identify optimization opportunities", + "- SELECT * retrieves all columns (wasteful if not all needed)", + "- Likely missing index on (active, created_at) combination", + "", + "Step 3: Propose improvements", + "- Create composite index: CREATE INDEX idx_users_active_created ON users(active, created_at)", + "- Replace SELECT * with specific columns if possible", + ], + "output": "CREATE INDEX idx_users_active_created ON users(active, created_at);\nSELECT id, email, name FROM users WHERE active = 1 AND created_at > '2025-01-01';" + } +] +``` + +**Bad:** +```python +COT_EXAMPLES = [ + { + "input": "Optimize query: SELECT * FROM users WHERE active = 1", + "output": "Add an index" # No reasoning shown + } +] +``` + +**Why It Matters:** Chain-of-thought examples teach models systematic reasoning processes.

Beyond 5-7 examples, accuracy improvements plateau but costs continue rising. + - How to avoid: Start with 3 examples, measure accuracy, add more only if improvement justifies token cost. Use example pruning techniques to identify non-contributing examples. + +2. **Examples Too Similar**: Using near-identical examples wastes tokens without teaching the model anything new. Redundant examples provide no additional information about edge cases or variations. + - How to avoid: Ensure examples cover different complexity levels, input formats, and edge cases. Use diversity metrics like cosine distance between example embeddings to verify coverage. + +3. **Incomplete or Placeholder Examples**: Examples with "TODO" comments, incomplete logic, or missing error handling teach models to produce incomplete code. Models learn the pattern you show, including the incompleteness. + - How to avoid: Every example must be production-quality code that actually runs. Test examples as part of your build process. Never include placeholder or sketch code. + +4. **Inconsistent Formatting Across Examples**: When examples use different styles, naming conventions, or structures, models learn that inconsistency is acceptable. Output becomes unpredictable. + - How to avoid: Establish and document formatting standards. Use linters and formatters on example code. Review examples for consistency during code review. + +5. **Missing Edge Case Examples**: Only showing happy-path examples leaves models unprepared for errors, null values, empty inputs, or boundary conditions. Models assume inputs are always well-formed. + - How to avoid: Include at least one example showing error handling, one with edge cases (empty lists, null values), and one with boundary conditions (max/min values). + +6. **Static Examples for Dynamic Tasks**: Using the same examples regardless of input context means models don't see relevant demonstrations. A query about error handling gets examples about API design. + - How to avoid: Implement dynamic example selection using similarity search or keyword matching. Select examples that match the current task's domain and complexity. + +7. **Not Measuring Example Contribution**: Including examples without measuring their impact on accuracy means you may be wasting tokens on unhelpful demonstrations. + - How to avoid: A/B test example sets.

Instead of jumping directly to an answer, the model articulates its thinking process, making reasoning transparent and improving accuracy on multi-step problems. + +## Why This Matters for AI-First Development + +When AI agents tackle complex problems, they benefit from explicit reasoning scaffolds just as humans do. Without structured thinking, models often miss critical steps, make logical leaps, or produce confident but incorrect answers. Chain-of-thought systems address this by creating space for deliberate reasoning. + +AI agents building and maintaining code face particularly challenging reasoning demands. They must trace execution paths, evaluate multiple approaches, verify logical consistency, and predict edge casesβ€”all while maintaining coherent context across potentially hundreds of steps. CoT systems provide the structured reasoning framework that makes this possible. + +Chain-of-thought systems deliver three critical benefits for AI-first development: + +1. **Improved accuracy on complex tasks**: Research consistently shows CoT prompting improves performance on mathematical reasoning, logical inference, and multi-step problem-solving by 16-54% depending on task complexity. Models using cognitive tools with CoT outperformed base models by 16.6% on mathematical benchmarks, with even advanced models like GPT-4 showing substantial gains. + +2. **Transparent reasoning for debugging**: When AI agents make mistakes, explicit reasoning traces make failures diagnosable. Instead of opaque wrong answers, you can see exactly where reasoning broke downβ€”whether it was a faulty assumption, missed constraint, or logical error. This transparency is essential when agents operate autonomously. + +3. **Reliable multi-step execution**: Complex workflows require maintaining context and consistency across many steps. CoT systems provide the scaffolding for agents to track their progress, verify intermediate results, and backtrack when needed. This is especially valuable in tool use chains, policy-heavy environments, and sequential decision-making. + +Without chain-of-thought systems, AI agents become unreliable black boxes. They might solve simple problems quickly but fail catastrophically on anything requiring multi-step reasoning. In production systems where agents operate with minimal human oversight, this brittleness is unacceptable. + +## Implementation Approaches + +### 1. **Zero-Shot Chain-of-Thought** + +The simplest CoT approach: add "Let's think step by step" to your prompt. + +When to use: Quick improvement on any reasoning task without examples. Works surprisingly well despite its simplicity. Best for problems where the reasoning structure is relatively standard. + +Success looks like: The model naturally breaks down the problem, shows its work, and reaches correct conclusions more often than with direct prompting. + +```python +def solve_with_zero_shot_cot(problem: str, model) -> str: + """Apply zero-shot CoT by adding a thinking prompt.""" + prompt = f""" + {problem} + + Let's think step by step: + """ + return model.generate(prompt) + +# Example usage +problem = "If a train leaves Station A at 2pm traveling at 60mph, and another leaves Station B at 3pm traveling at 80mph toward Station A, and the stations are 200 miles apart, when do they meet?" +answer = solve_with_zero_shot_cot(problem, model) +``` + +### 2. **Few-Shot Chain-of-Thought with Examples** + +Provide 2-3 examples of complete reasoning chains before the actual problem. + +When to use: When you need more control over the reasoning structure or when zero-shot CoT doesn't capture domain-specific reasoning patterns. Essential for specialized domains or complex reasoning steps. + +Success looks like: The model follows the example pattern, producing similarly structured reasoning that's appropriate for your domain. + +```python +def solve_with_few_shot_cot(problem: str, examples: list[dict], model) -> str: + """Apply few-shot CoT with reasoning examples.""" + prompt_parts = ["Here are examples of how to solve similar problems:\n"] + + for i, example in enumerate(examples, 1): + prompt_parts.append(f"\nExample {i}:") + prompt_parts.append(f"Problem: {example['problem']}") + prompt_parts.append(f"Reasoning: {example['reasoning']}") + prompt_parts.append(f"Answer: {example['answer']}\n") + + prompt_parts.append(f"\nNow solve this problem using the same reasoning approach:") + prompt_parts.append(f"Problem: {problem}") + prompt_parts.append("Reasoning:") + + return model.generate("\n".join(prompt_parts)) + +# Example usage +examples = [ + { + "problem": "What is 15% of 80?", + "reasoning": "Step 1: Convert percentage to decimal: 15% = 0.15\nStep 2: Multiply: 0.15 Γ— 80 = 12", + "answer": "12" + }, + { + "problem": "What is 25% of 60?", + "reasoning": "Step 1: Convert percentage to decimal: 25% = 0.25\nStep 2: Multiply: 0.25 Γ— 60 = 15", + "answer": "15" + } +] +answer = solve_with_few_shot_cot("What is 18% of 150?", examples, model) +``` + +### 3. **Tree-of-Thought (Exploring Multiple Paths)** + +Generate and evaluate multiple reasoning paths, exploring different approaches simultaneously. + +When to use: Complex problems with multiple valid solution approaches, strategic planning, or when you need to find the best solution among several possibilities. Essential for tasks requiring lookahead and backtracking. + +Success looks like: The system explores promising paths, prunes unlikely ones, and converges on the best solution even when the optimal path isn't obvious initially. + +```python +def solve_with_tree_of_thought( + problem: str, + num_candidates: int = 5, + depth: int = 3, + model +) -> str: + """ + Implement Tree-of-Thought reasoning with branching exploration. + """ + def generate_thoughts(state: str, step: int) -> list[str]: + """Generate candidate next thoughts for current state.""" + prompt = f""" + Current problem state: {state} + Step {step} of {depth} + + Generate {num_candidates} different possible next steps or approaches. + Each should be a distinct way to proceed. + Format as numbered list. + """ + response = model.generate(prompt) + return [t.strip() for t in response.split('\n') if t.strip()] + + def evaluate_thought(thought: str, goal: str) -> str: + """Evaluate if this thought is promising (sure/maybe/impossible).""" + prompt = f""" + Goal: {goal} + Current thought: {thought} + + Evaluate if this approach can lead to the goal. + Respond with only: "sure", "maybe", or "impossible" + """ + return model.generate(prompt).strip().lower() + + # Initialize with problem + current_thoughts = [(problem, 1.0)] # (state, score) + + for step in range(depth): + next_thoughts = [] + + for state, score in current_thoughts: + # Generate candidate next thoughts + candidates = generate_thoughts(state, step + 1) + + # Evaluate each candidate + for candidate in candidates[:num_candidates]: + evaluation = evaluate_thought(candidate, problem) + + # Score based on evaluation + if evaluation == "sure": + new_score = score * 1.0 + elif evaluation == "maybe": + new_score = score * 0.7 + else: # impossible + continue # Prune this branch + + next_thoughts.append((f"{state}\n{candidate}", new_score)) + + # Keep best candidates for next iteration + current_thoughts = sorted(next_thoughts, key=lambda x: x[1], reverse=True)[:num_candidates] + + # Return the best path + return current_thoughts[0][0] if current_thoughts else "No solution found" +``` + +### 4. **Self-Consistency via Multiple Sampling** + +Generate multiple independent reasoning chains and select the most common answer. + +When to use: When accuracy is critical and you can afford extra inference cost. Particularly effective for problems with discrete answers where multiple reasoning paths should converge to the same solution. + +Success looks like: Different reasoning chains reach the same answer through different approaches, increasing confidence. Disagreement highlights areas of genuine uncertainty. + +```python +def solve_with_self_consistency( + problem: str, + num_samples: int = 5, + model +) -> tuple[str, float]: + """ + Generate multiple reasoning chains and select most common answer. + Returns (answer, confidence) where confidence is agreement ratio. + """ + reasoning_chains = [] + answers = [] + + # Generate multiple independent chains + for _ in range(num_samples): + prompt = f""" + {problem} + + Let's think step by step to solve this: + """ + chain = model.generate(prompt, temperature=0.7) + reasoning_chains.append(chain) + + # Extract final answer from chain + answer = extract_final_answer(chain) + answers.append(answer) + + # Find most common answer + from collections import Counter + answer_counts = Counter(answers) + best_answer, count = answer_counts.most_common(1)[0] + confidence = count / num_samples + + return best_answer, confidence + +def extract_final_answer(chain: str) -> str: + """Extract the final answer from a reasoning chain.""" + # Look for common answer indicators + lines = chain.split('\n') + for line in reversed(lines): + if any(indicator in line.lower() for indicator in ['answer:', 'therefore', 'thus', 'final answer']): + return line.strip() + return lines[-1].strip() +``` + +### 5. **The "Think" Tool for Agentic Systems** + +Provide a dedicated tool that agents can call to process information between actions. + +When to use: Agentic tool use scenarios, especially policy-heavy environments, sequential decision-making, or when analyzing tool outputs before taking further actions.

Direct answers hide the logic, making errors impossible to diagnose. When AI agents make decisions autonomously, opaque reasoning is unacceptableβ€”you need to see the thinking to trust the output. + +### Example 2: Code Debugging + +**Good:** +```python +def debug_with_cot(code: str, error: str) -> str: + """Debug code with structured reasoning.""" + prompt = f""" + Code with error: + {code} + + Error message: + {error} + + Let's debug this systematically: + + 1.

Prompt patterns provide the foundation; CoT adds systematic reasoning scaffolds. + +- **[Principle #47 - Context Engineering](47-context-engineering.md)** - CoT reasoning consumes significant context. Effective context engineering determines how many reasoning steps fit in the model's context window and how to structure chains efficiently. + +- **[Principle #49 - Tool Use Patterns](49-tool-use-patterns.md)** - The "think" tool exemplifies how CoT integrates with agentic tool use. CoT helps agents reason about when to use tools, how to interpret tool results, and how to chain tool calls effectively. + +- **[Principle #52 - Multi-Agent Systems](52-multi-agent-systems.md)** - Multi-agent systems benefit from CoT when agents need to reason about their roles, coordinate actions, or explain their decisions to other agents. Tree-of-thought enables exploring multiple agent strategies simultaneously. + +- **[Principle #26 - Stateless by Default](26-stateless-by-default.md)** - CoT reasoning chains should be statelessβ€”each step can be understood independently. This enables caching, parallel exploration (as in ToT), and easier debugging of reasoning failures. + +- **[Principle #32 - Error Recovery Patterns Built In](32-error-recovery-patterns.md)** - CoT enhances error recovery because explicit reasoning makes failures diagnosable. When errors occur, you can identify which reasoning step failed and why, enabling targeted correction. + +## Common Pitfalls + +1. **Overusing CoT on Simple Tasks**: Applying CoT to trivial problems wastes tokens and adds latency without improving accuracy. + - Example: Using "let's think step by step" for "What is 2+2?" adds 20-50 tokens for zero benefit. + - Impact: Increased costs, slower responses, cluttered outputs. Can reduce user experience by adding unnecessary verbosity. + - Solution: Use direct prompting for simple tasks. Reserve CoT for problems requiring multi-step reasoning, policy verification, or complex analysis. + +2. **Not Providing Reasoning Structure**: Zero-shot "think step by step" works but isn't optimal for complex domains. + - Example: Asking the model to debug code without specifying what aspects to analyze (error type, root cause, edge cases, etc.). + - Impact: Shallow or incomplete reasoning. Model might skip critical steps or focus on irrelevant details. + - Solution: Use few-shot examples or explicit reasoning templates for domain-specific tasks. Show the model what good reasoning looks like in your context. + +3. **Ignoring Cost-Benefit Trade-offs**: CoT dramatically increases token usageβ€”reasoning chains can be 3-10x longer than direct answers. + - Example: Using self-consistency with 5 samples on every query increases costs 5x and latency significantly. + - Impact: Unsustainable costs at scale. $100/day API budget becomes $500/day without proportional value gain. + - Solution: Measure task accuracy with and without CoT. Use CoT only where error reduction justifies cost increase. Consider caching reasoning chains for common problems. + +4. **Missing Verification Steps**: Generating reasoning chains without validating them allows errors to propagate. + - Example: Model produces multi-step solution but never verifies intermediate results or final answer correctness. + - Impact: Confidently wrong answers that look superficially correct due to detailed reasoning. Harder to spot errors in long reasoning chains. + - Solution: Add explicit verification steps. For critical tasks, use self-consistency to catch errors through disagreement between chains. + +5. **Treating All CoT Steps Equally**: Not all reasoning steps require the same depth or contribute equally to final accuracy. + - Example: Spending 100 tokens on "Step 1: Understand the problem" when it's trivial, then rushing through complex calculation steps. + - Impact: Wasted tokens on obvious steps, insufficient reasoning on hard steps. Suboptimal token allocation. + - Solution: Use adaptive CoT depth. Allocate more reasoning budget to complex steps, less to obvious ones. Learn which steps matter most for your domain. + +6. **No Structured Storage of Reasoning Chains**: Treating reasoning chains as ephemeral text instead of structured data for analysis. + - Example: Logging raw text outputs without parsing steps, decisions, or confidence levels. + - Impact: Can't analyze failure patterns, measure reasoning quality, or improve prompts based on data. No visibility into what reasoning works best. + - Solution: Parse and structure reasoning chains. Track which steps succeed/fail, measure agreement in self-consistency, identify common error patterns. + +7. **Forgetting Temperature Settings**: Using inappropriate temperature for CoT sampling. + - Example: Using temperature=0.0 for self-consistency, which produces identical chains instead of diverse reasoning paths. + - Impact: Self-consistency provides no benefit if all chains are identical. Tree-of-thought fails to explore diverse strategies. + - Solution: Use temperature=0.0 for deterministic reasoning when you want reproducibility. Use temperature=0.7-0.9 for self-consistency and ToT to ensure diverse exploration. + +## Tools & Frameworks + +### Chain-of-Thought Libraries +- **LangChain**: Built-in CoT chains with sequential execution, custom reasoning templates, and result parsing.

Instead of just generating text, agents can query databases, call APIs, manipulate files, perform calculations, and orchestrate complex workflows through a catalog of well-defined tools. + +## Why This Matters for AI-First Development + +When AI agents build and maintain systems, they need more than language generationβ€”they need the ability to act. Tool use transforms agents from passive observers into active participants in software development. An agent that can only generate code suggestions is limited; an agent that can execute tests, query documentation, modify files, and deploy changes becomes a true development partner. + +Tool use provides three critical capabilities for AI-driven development: + +1. **Grounding in reality**: Tools connect agents to actual system state. Instead of hallucinating file contents or API responses, agents can retrieve real data, making their decisions based on facts rather than assumptions. This grounding is essential for reliable code generation and system modification. + +2. **Action at scale**: Tools enable agents to perform thousands of operations that would take humans hours or days. An agent with file system access can refactor an entire codebase, analyze hundreds of logs, or validate configurations across dozens of servicesβ€”all while maintaining consistency and following defined patterns. + +3. **Iterative refinement through feedback**: When tools return results, agents can observe outcomes and adjust their approach. A test failure becomes feedback for code improvement. An API error message guides retry logic. This create-observe-refine loop is how agents learn to solve problems effectively. + +Without effective tool use, AI agents remain theoretical. They can describe what should be done but can't actually do it. They can suggest fixes but can't verify them. They can generate code but can't test it. Poor tool design leads to agents that call the wrong functions, pass malformed parameters, ignore error messages, or make thousands of unnecessary API calls. The difference between an effective agent and a frustrating one often comes down to how well its tools are designed and documented. + +## Implementation Approaches + +### 1. **Structured Tool Definitions with JSON Schema** + +Define tools using explicit schemas that specify input parameters, output formats, and behavior: + +```python +from pydantic import BaseModel, Field +from typing import Optional, List + +class SearchCodeParams(BaseModel): + """Parameters for searching codebase.""" + pattern: str = Field( + description="Regex pattern to search for. Use proper escaping." + ) + file_types: Optional[List[str]] = Field( + default=None, + description="File extensions to search (e.g., ['.py', '.js']). Omit for all files." + ) + case_sensitive: bool = Field( + default=False, + description="Whether pattern matching is case-sensitive" + ) + +def search_code(pattern: str, file_types: Optional[List[str]] = None, + case_sensitive: bool = False) -> dict: + """ + Search codebase for pattern matches. + + Returns dictionary with 'matches' (list of {file, line, content}) + and 'total_count' (int). Limited to 100 matches. + """ + # Implementation + pass +``` + +**When to use**: When building new tools or refactoring existing ones. Strong typing prevents parameter errors and makes tool behavior predictable. + +**Success looks like**: Agents rarely call tools with invalid parameters. Type errors are caught before execution, not during. + +### 2. **Namespaced Tool Collections** + +Group related tools under common prefixes to help agents select the right function: + +```python +# File operations namespace +def file_read(path: str) -> str: pass +def file_write(path: str, content: str) -> None: pass +def file_search(directory: str, pattern: str) -> List[str]: pass + +# Database operations namespace +def db_query(sql: str) -> List[dict]: pass +def db_execute(sql: str) -> int: pass +def db_schema(table: str) -> dict: pass + +# API operations namespace +def api_get(endpoint: str) -> dict: pass +def api_post(endpoint: str, data: dict) -> dict: pass +def api_list(service: str) -> List[str]: pass +``` + +**When to use**: When you have more than 10-15 tools, or when tools from different services might overlap in functionality (e.g., multiple search tools). + +**Success looks like**: Agents naturally select the right tool family, reducing confusion between similar operations from different services. + +### 3. **Concise vs Detailed Response Modes** + +Allow agents to control the verbosity of tool responses: + +```python +from enum import Enum + +class ResponseFormat(str, Enum): + CONCISE = "concise" # Human-readable summary + DETAILED = "detailed" # Full technical details + IDS_ONLY = "ids" # Just identifiers for chaining + +def search_users( + query: str, + format: ResponseFormat = ResponseFormat.CONCISE +) -> dict: + """Search users by name or email. + + CONCISE: Returns name, email (72 tokens avg) + DETAILED: Includes ID, created_at, roles, metadata (206 tokens avg) + IDS_ONLY: Just user IDs for further operations (15 tokens avg) + """ + users = db.search(query) + + if format == ResponseFormat.IDS_ONLY: + return {"user_ids": [u.id for u in users]} + elif format == ResponseFormat.DETAILED: + return {"users": [u.to_dict() for u in users]} + else: # CONCISE + return {"users": [{"name": u.name, "email": u.email} for u in users]} +``` + +**When to use**: For tools that return variable amounts of data, especially when some calls are exploratory (need summaries) vs targeted (need full details). + +**Success looks like**: Agents spend fewer tokens on tool responses while still getting necessary information. Context windows last longer. + +### 4. **Helpful Error Messages with Recovery Guidance** + +Design error responses to guide agents toward correct usage: + +```python +def deploy_service(service_name: str, version: str) -> dict: + """Deploy a service to production.""" + + # Validate service exists + if not service_exists(service_name): + return { + "error": "SERVICE_NOT_FOUND", + "message": f"Service '{service_name}' does not exist", + "suggestion": "Use list_services() to see available services", + "available_services": list_services()[:5] # Show first 5 + } + + # Validate version format + if not is_valid_version(version): + return { + "error": "INVALID_VERSION", + "message": f"Version '{version}' is not valid", + "suggestion": "Use semantic versioning format (e.g., '1.2.3')", + "example": "deploy_service('api-gateway', '2.1.0')" + } + + # Proceed with deployment + result = perform_deployment(service_name, version) + return {"status": "deployed", "service": service_name, "version": version} +``` + +**When to use**: For all tools where parameter validation can fail or where agents might misunderstand tool capabilities. + +**Success looks like**: Agents self-correct based on error messages without human intervention. Fewer repeated parameter errors. + +### 5. **Token-Efficient Results with Pagination** + +Limit response sizes and provide continuation mechanisms: + +```python +def search_logs( + query: str, + max_results: int = 50, + include_context: bool = True +) -> dict: + """Search application logs. + + Args: + max_results: Limit results (1-100, default 50) + include_context: Include surrounding log lines (adds ~30% tokens) + """ + if max_results > 100: + max_results = 100 # Hard cap + + matches = perform_search(query) + limited = matches[:max_results] + + response = { + "matches": limited, + "total_found": len(matches), + "returned": len(limited) + } + + if len(matches) > max_results: + response["truncated"] = True + response["suggestion"] = ( + f"Results limited to {max_results}. Found {len(matches)} total. " + f"Use more specific query or filter by time range." + ) + + return response +``` + +**When to use**: For any tool that queries or retrieves collections of items (logs, files, records, search results). + +**Success looks like**: Responses stay under 25,000 tokens. Agents naturally refine queries when results are truncated. + +### 6. **Parallel Tool Execution Patterns** + +Enable agents to call multiple tools simultaneously when operations are independent: + +```python +from typing import List, Dict, Any +import asyncio + +async def execute_tools_parallel(tool_calls: List[Dict[str, Any]]) -> List[Any]: + """Execute multiple tool calls in parallel. + + Args: + tool_calls: List of {tool_name, parameters} dicts + + Returns: + List of results in same order as tool_calls + """ + async def call_tool(tool_info): + tool_name = tool_info["tool_name"] + params = tool_info["parameters"] + return await TOOL_REGISTRY[tool_name](**params) + + tasks = [call_tool(tc) for tc in tool_calls] + results = await asyncio.gather(*tasks, return_exceptions=True) + return results + +# Example: Agent can request parallel execution +parallel_request = [ + {"tool_name": "file_read", "parameters": {"path": "src/main.py"}}, + {"tool_name": "file_read", "parameters": {"path": "tests/test_main.py"}}, + {"tool_name": "db_schema", "parameters": {"table": "users"}} +] +results = await execute_tools_parallel(parallel_request) +``` + +**When to use**: When building agent frameworks that support multi-step workflows where some operations don't depend on each other. + +**Success looks like**: Agents complete multi-step tasks faster. Read operations happen in parallel before analysis begins. + +## Good Examples vs Bad Examples + +### Example 1: File Search Tool Definition + +**Good:** +```python +def search_files( + pattern: str, + directory: str = ".", + file_extensions: Optional[List[str]] = None, + case_sensitive: bool = False, + max_results: int = 100 +) -> dict: + """ + Search files for text pattern using regex. + + Args: + pattern: Regular expression pattern (e.g., 'def.*\\(.*\\):' for Python functions) + directory: Starting directory (default: current directory) + file_extensions: Filter by extensions (e.g., ['.py', '.js']). None = all files. + case_sensitive: Whether pattern matching is case-sensitive + max_results: Maximum matches to return (1-1000, default 100) + + Returns: + { + "matches": [{"file": str, "line": int, "content": str}], + "total_found": int, + "truncated": bool + } + + Example: + search_files(pattern='TODO', file_extensions=['.py'], max_results=10) + """ + pass +``` + +**Bad:** +```python +def search(q: str, d: str = None, ext: list = None) -> list: + """Search for pattern in files.""" + # Unclear what 'q', 'd', 'ext' mean + # No indication of regex support + # Return type too vague + # No example usage + pass +``` + +**Why It Matters:** The good example provides clear parameter names, detailed descriptions, expected formats, and usage examples. Agents can call this tool correctly on first try. The bad example requires agents to guess or experiment, leading to errors. + +### Example 2: API Call Error Handling + +**Good:** +```python +def call_external_api(endpoint: str, method: str = "GET", + data: Optional[dict] = None) -> dict: + """Call external REST API.""" + try: + response = requests.request(method, endpoint, json=data) + response.raise_for_status() + return {"success": True, "data": response.json()} + + except requests.HTTPError as e: + if e.response.status_code == 404: + return { + "error": "NOT_FOUND", + "message": f"Endpoint {endpoint} does not exist", + "suggestion": "Verify the endpoint path. Use list_endpoints() to see available paths.", + "status_code": 404 + } + elif e.response.status_code == 401: + return { + "error": "UNAUTHORIZED", + "message": "Authentication required", + "suggestion": "Check that API credentials are configured correctly", + "status_code": 401 + } + return {"error": "HTTP_ERROR", "message": str(e), "status_code": e.response.status_code} +``` + +**Bad:** +```python +def call_external_api(endpoint: str, method: str = "GET", + data: Optional[dict] = None) -> dict: + """Call external REST API.""" + response = requests.request(method, endpoint, json=data) + response.raise_for_status() # Throws exception, agent can't handle + return response.json() +``` + +**Why It Matters:** The good example catches errors and returns structured information that agents can act on. The bad example throws exceptions that interrupt agent execution. Agents need error information as data, not as exceptions. + +### Example 3: Database Query Results + +**Good:** +```python +def query_database( + sql: str, + format: ResponseFormat = ResponseFormat.CONCISE +) -> dict: + """Execute SQL query and return results. + + CONCISE: Returns row count and first 5 rows (fast, low token count) + DETAILED: Returns all rows with column types (comprehensive) + """ + results = db.execute(sql) + + if format == ResponseFormat.CONCISE: + return { + "row_count": len(results), + "sample_rows": results[:5], + "truncated": len(results) > 5, + "columns": list(results[0].keys()) if results else [] + } + else: # DETAILED + return { + "rows": results, + "row_count": len(results), + "columns": get_column_info(results) + } +``` + +**Bad:** +```python +def query_database(sql: str) -> List[dict]: + """Execute SQL query.""" + return db.execute(sql) # Returns all rows, could be thousands + # No indication of size + # No way to request summary + # No column information +``` + +**Why It Matters:** Large result sets consume agent context windows. The good example provides control over verbosity and prevents context overflow. The bad example might return 10,000 rows when agent only needed to verify data exists. + +### Example 4: Tool Parameter Validation + +**Good:** +```python +def deploy_application( + app_name: str, + environment: str, + version: str +) -> dict: + """Deploy application to specified environment.""" + + # Validate inputs with helpful feedback + valid_envs = ["dev", "staging", "production"] + if environment not in valid_envs: + return { + "error": "INVALID_ENVIRONMENT", + "message": f"Environment must be one of: {valid_envs}", + "provided": environment, + "suggestion": f"Did you mean '{find_closest_match(environment, valid_envs)}'?" + } + + if not app_exists(app_name): + return { + "error": "APP_NOT_FOUND", + "available_apps": list_apps()[:10], + "suggestion": "Use list_apps() to see all applications" + } + + # Proceed with deployment + return deploy(app_name, environment, version) +``` + +**Bad:** +```python +def deploy_application(app_name: str, environment: str, version: str) -> dict: + """Deploy application.""" + # No validation + return deploy(app_name, environment, version) # Fails cryptically on invalid input +``` + +**Why It Matters:** Input validation with helpful messages guides agents toward correct usage. The bad example fails silently or with cryptic errors, forcing agents to guess correct values. + +### Example 5: File Operations with Idempotency + +**Good:** +```python +def write_file(path: str, content: str, create_dirs: bool = True) -> dict: + """ + Write content to file, replacing if exists. + + Idempotent: writing same content multiple times produces same result. + """ + file_path = Path(path) + + if create_dirs: + file_path.parent.mkdir(parents=True, exist_ok=True) + + file_path.write_text(content) + + return { + "success": True, + "path": str(file_path), + "size_bytes": len(content), + "created": not file_path.existed_before_write # Track for agent awareness + } +``` + +**Bad:** +```python +def append_to_file(path: str, content: str) -> None: + """Append content to file.""" + with open(path, 'a') as f: # Append mode + f.write(content) + # Not idempotent - multiple calls accumulate content + # No feedback about what happened +``` + +**Why It Matters:** The good example is idempotent (safe to retry) and provides feedback. The bad example breaks on retry, causing data duplication when agents encounter errors. + +## Related Principles + +- **[Principle #48 - Chain-of-Thought Reasoning](48-chain-of-thought-reasoning.md)** - Tools enable agents to ground reasoning in external facts. Chain-of-thought helps agents decide which tools to call and in what order. + +- **[Principle #52 - Multi-Agent Orchestration](52-multi-agent-orchestration.md)** - Tool use enables agents to coordinate actions. Each agent uses tools to communicate results and trigger downstream operations. + +- **[Principle #31 - Idempotency by Design](31-idempotency-by-design.md)** - Tools must be idempotent so agents can safely retry operations. Tool design should assume calls may be retried on failure. + +- **[Principle #29 - Tool Ecosystems and MCP](29-tool-ecosystems-mcp.md)** - Model Context Protocol provides standardized way to define and discover tools. Tool implementations should follow MCP conventions. + +- **[Principle #32 - Error Recovery Patterns](32-error-recovery-patterns.md)** - Tool error responses should enable recovery. Return structured errors that agents can handle programmatically. + +- **[Principle #26 - Stateless by Default](26-stateless-by-default.md)** - Stateless tools are easier for agents to reason about. Each tool call should be independent when possible. + +## Common Pitfalls + +1. **Vague Tool Descriptions** + - Example: `def process_data(data): """Process the data."""` + - Impact: Agents don't know what "process" means, what data format is expected, or what output to expect. Results in trial-and-error tool calling. + - How to avoid: Write descriptions like you're explaining to a junior developer. Include input format, output format, side effects, and examples. + +2. **Returning Technical IDs Instead of Human-Readable Values** + - Example: Returning `user_uuid='f47ac10b-58cc-4372-a567-0e02b2c3d479'` instead of `user_name='jane@example.com'` + - Impact: Agents can't reason about UUIDs naturally. They hallucinate or ignore identifier fields. + - How to avoid: Return semantic identifiers (names, emails, readable codes) for agent reasoning, with technical IDs available in "detailed" mode. + +3. **No Token Limits on Tool Responses** + - Example: `list_files()` returns all 5,000 files in directory consuming 50,000 tokens + - Impact: Single tool call exhausts agent's context window, preventing further reasoning or tool use. + - How to avoid: Implement max_results parameters (default to ~50-100), pagination, and truncation warnings. + +4. **Throwing Exceptions Instead of Returning Error Data** + - Example: Tool raises `FileNotFoundError` when file doesn't exist + - Impact: Exception breaks agent execution. Agent can't learn from error or try alternative approaches. + - How to avoid: Catch exceptions and return structured error objects with suggestions for recovery. + +5. **Overlapping Tool Functionality Without Clear Boundaries** + - Example: Having both `search_users()`, `find_users()`, and `get_users()` that do similar things + - Impact: Agents get confused about which tool to use, making wrong choices or trying all three. + - How to avoid: Consolidate similar tools.

Retrieval-Augmented Generation + +## Plain-Language Definition + +Retrieval-Augmented Generation (RAG) enhances AI model responses by retrieving relevant information from external knowledge sources and using that context to generate more accurate, factual answers. Instead of relying solely on the model's training data, RAG systems fetch up-to-date information at query time, making responses grounded in actual evidence rather than hallucinated facts. + +## Why This Matters for AI-First Development + +When AI agents build and maintain systems, they need access to current, domain-specific knowledge that wasn't part of their training. A customer support bot needs to know about last week's product updates. A legal research assistant needs access to recent case law. A code documentation agent needs to understand the latest API changes. Without RAG, AI systems are limited to stale parametric knowledge frozen at training time. + +RAG provides three critical benefits for AI-driven development: + +1. **Dynamic knowledge without retraining**: AI agents can access the latest information without expensive model updates. When your product documentation changes or new code is committed, RAG systems automatically incorporate this knowledge into responses. This is essential for agents operating in fast-moving environments where facts evolve continuously. + +2. **Factual grounding reduces hallucination**: By anchoring responses in retrieved evidence, RAG dramatically reduces the model's tendency to fabricate information. When an AI agent cites specific documentation or code comments it retrieved, the response becomes verifiable and trustworthy. This is critical for production systems where accuracy matters. + +3. **Domain specialization without fine-tuning**: RAG enables AI systems to become experts in specific domains by simply pointing them at relevant knowledge bases. A general-purpose model becomes a specialist in your codebase, your company's policies, or your technical documentationβ€”without any model training. This makes AI-first development practical for organizations without ML expertise. + +Without RAG, AI-first systems face severe limitations. Agents working with code repositories would miss recent commits and documentation updates. Customer-facing bots would provide outdated information about products and policies. Research assistants would cite non-existent papers or misrepresent findings. These failures compound quickly when agents operate autonomously without human verification at every step. + +## Implementation Approaches + +### 1. **Basic Semantic Search RAG** + +The simplest RAG implementation uses embedding similarity to find relevant context. Documents are split into chunks, embedded into vectors, and stored in a vector database. At query time, the query is embedded and compared against stored chunks using cosine similarity. + +When to use: Good for well-structured documentation, knowledge bases with clear semantic relationships, and scenarios where semantic meaning matters more than exact keyword matches. + +```python +from openai import OpenAI +import numpy as np +from sklearn.metrics.pairwise import cosine_similarity + +def basic_rag_query(query: str, documents: list[str], client: OpenAI, top_k: int = 3) -> str: + """Basic RAG using semantic similarity search.""" + # Embed all documents + doc_embeddings = [] + for doc in documents: + response = client.embeddings.create( + model="text-embedding-ada-002", + input=doc + ) + doc_embeddings.append(response.data[0].embedding) + + # Embed the query + query_response = client.embeddings.create( + model="text-embedding-ada-002", + input=query + ) + query_embedding = query_response.data[0].embedding + + # Find most similar documents + similarities = cosine_similarity( + [query_embedding], + doc_embeddings + )[0] + + # Get top-k most relevant documents + top_indices = np.argsort(similarities)[-top_k:][::-1] + context = "\n\n".join([documents[i] for i in top_indices]) + + # Generate response with context + completion = client.chat.completions.create( + model="gpt-4", + messages=[ + {"role": "system", "content": "Answer based on the retrieved context."}, + {"role": "user", "content": f"Context:\n{context}\n\nQuestion: {query}"} + ] + ) + + return completion.choices[0].message.content +``` + +Success looks like: Responses accurately reflect information from the retrieved documents, with minimal hallucination and clear source attribution. + +### 2. **Contextual Retrieval with Chunk Enrichment** + +Standard chunking loses context when documents are split. Contextual retrieval prepends explanatory context to each chunk before embedding, dramatically improving retrieval accuracy. This technique uses an LLM to generate chunk-specific context from the full document. + +When to use: Essential for large document collections (SEC filings, legal documents, research papers) where individual chunks lack sufficient context to be understood in isolation. + +```python +def create_contextual_chunks(document: str, chunk_size: int = 1000) -> list[dict]: + """Split document into chunks with added context from the full document.""" + # Split into chunks (simplified for example) + chunks = [document[i:i+chunk_size] for i in range(0, len(document), chunk_size)] + + contextualized_chunks = [] + for chunk in chunks: + # Use LLM to add context + prompt = f""" +{document} + + +Here is the chunk we want to situate within the whole document: + +{chunk} + + +Please give a short succinct context to situate this chunk within the overall document for the purposes of improving search retrieval of the chunk. Answer only with the succinct context and nothing else.""" + + response = client.chat.completions.create( + model="claude-3-haiku-20240307", + messages=[{"role": "user", "content": prompt}] + ) + + context = response.choices[0].message.content + contextualized_chunk = f"{context}\n\n{chunk}" + + contextualized_chunks.append({ + "original": chunk, + "contextualized": contextualized_chunk, + "context": context + }) + + return contextualized_chunks +``` + +Success looks like: 35-49% reduction in retrieval failures compared to standard chunking, especially for queries requiring cross-chunk understanding. + +### 3. **Hybrid Search (BM25 + Semantic)** + +Combining lexical matching (BM25) with semantic embeddings captures both exact term matches and conceptual similarity. This is particularly effective when queries include technical terms, error codes, or specific identifiers that semantic search might miss. + +When to use: Technical documentation, code search, medical/legal texts with specific terminology, or any domain where exact phrase matching matters alongside semantic understanding. + +```python +from rank_bm25 import BM25Okapi +import numpy as np + +def hybrid_search(query: str, documents: list[str], embeddings: np.ndarray, + query_embedding: np.ndarray, bm25_weight: float = 0.3) -> list[int]: + """Combine BM25 and semantic search with weighted fusion.""" + # BM25 search + tokenized_docs = [doc.lower().split() for doc in documents] + bm25 = BM25Okapi(tokenized_docs) + tokenized_query = query.lower().split() + bm25_scores = bm25.get_scores(tokenized_query) + + # Normalize BM25 scores to 0-1 + bm25_scores = (bm25_scores - bm25_scores.min()) / (bm25_scores.max() - bm25_scores.min() + 1e-9) + + # Semantic search + semantic_scores = cosine_similarity([query_embedding], embeddings)[0] + + # Combine scores with weighting + embedding_weight = 1.0 - bm25_weight + combined_scores = (bm25_weight * bm25_scores) + (embedding_weight * semantic_scores) + + # Return indices sorted by combined score + return np.argsort(combined_scores)[::-1] +``` + +Success looks like: Better handling of queries with specific terms (error codes, product names) while maintaining semantic understanding for conceptual queries. + +### 4. **Reranking with Cross-Encoder** + +Initial retrieval often returns many candidates with varying relevance. Reranking uses a more sophisticated model to score each candidate's relevance to the query, then selects only the most pertinent results for generation. + +When to use: When you can afford extra latency for better accuracy, especially for critical applications like medical diagnosis, legal research, or financial analysis where retrieval precision is paramount. + +```python +def retrieve_and_rerank(query: str, documents: list[str], + initial_k: int = 150, final_k: int = 20) -> list[str]: + """Retrieve many candidates, then rerank for final selection.""" + # Initial retrieval (broad) + initial_results = hybrid_search(query, documents, initial_k) + candidates = [documents[i] for i in initial_results] + + # Rerank with cross-encoder (using Cohere reranker as example) + import cohere + co = cohere.Client(api_key="...") + + rerank_response = co.rerank( + query=query, + documents=candidates, + top_n=final_k, + model="rerank-english-v2.0" + ) + + # Extract top reranked documents + reranked_docs = [ + candidates[result.index] + for result in rerank_response.results + ] + + return reranked_docs +``` + +Success looks like: 67% reduction in retrieval failures when combined with contextual embeddings and BM25, with acceptable latency trade-off. + +### 5. **Adaptive Retrieval with Self-RAG** + +Not all queries need retrieval. Adaptive RAG decides when to retrieve based on the query type and generates reflection tokens to assess whether retrieved information is relevant and whether the response is supported by that information. + +When to use: Mixed workloads where some queries can be answered from parametric knowledge while others need external information, or when minimizing retrieval cost/latency is important. + +```python +def adaptive_rag_query(query: str, documents: list[str], client: OpenAI) -> str: + """Decide whether to retrieve based on query analysis.""" + # First, ask model if retrieval is needed + decision_prompt = f"""Does this query require external knowledge retrieval to answer accurately? +Query: {query} + +Respond with only 'YES' or 'NO'.""" + + decision = client.chat.completions.create( + model="gpt-4", + messages=[{"role": "user", "content": decision_prompt}], + max_tokens=5 + ) + + needs_retrieval = "YES" in decision.choices[0].message.content.upper() + + if not needs_retrieval: + # Answer directly without retrieval + return client.chat.completions.create( + model="gpt-4", + messages=[{"role": "user", "content": query}] + ).choices[0].message.content + + # Retrieve and answer with context + context = retrieve_context(query, documents) + + # Generate with reflection + response = client.chat.completions.create( + model="gpt-4", + messages=[ + {"role": "system", "content": "Answer based on retrieved context. Include [Supported] if the answer is well-supported by the context, or [Not Supported] if uncertain."}, + {"role": "user", "content": f"Context:\n{context}\n\nQuestion: {query}"} + ] + ) + + return response.choices[0].message.content +``` + +Success looks like: Reduced retrieval costs for simple queries while maintaining high accuracy on knowledge-intensive questions. + +### 6. **Iterative RAG for Multi-Step Reasoning** + +Complex queries require multiple retrieval cycles where each generation step informs what to retrieve next. This pattern alternates between generation and retrieval, using partial answers to guide subsequent searches. + +When to use: Multi-hop reasoning tasks, complex research questions, or scenarios where the answer requires synthesizing information from multiple sources in sequence. + +```python +def iterative_rag(query: str, documents: list[str], max_iterations: int = 3) -> str: + """Perform multiple retrieval-generation cycles for complex queries.""" + current_context = "" + partial_answer = "" + + for iteration in range(max_iterations): + # Determine what information is still needed + if iteration == 0: + search_query = query + else: + # Use partial answer to guide next retrieval + search_query = f"Given that {partial_answer}, what additional information is needed to answer: {query}" + + # Retrieve relevant documents + retrieved = retrieve_context(search_query, documents) + current_context += f"\n\nIteration {iteration+1} context:\n{retrieved}" + + # Generate partial answer + response = client.chat.completions.create( + model="gpt-4", + messages=[ + {"role": "system", "content": "Provide a partial answer based on available context. Identify what information is still missing."}, + {"role": "user", "content": f"Context:\n{current_context}\n\nQuestion: {query}"} + ] + ) + + partial_answer = response.choices[0].message.content + + # Check if we have enough information + if "[Complete]" in partial_answer: + break + + # Generate final answer with all retrieved context + final_response = client.chat.completions.create( + model="gpt-4", + messages=[ + {"role": "user", "content": f"Context:\n{current_context}\n\nQuestion: {query}\n\nProvide a complete final answer."} + ] + ) + + return final_response.choices[0].message.content +``` + +Success looks like: Ability to answer complex multi-step questions that require synthesizing information from multiple documents across several reasoning steps. + +## Good Examples vs Bad Examples + +### Example 1: Document Chunking Strategy + +**Good:** +```python +def chunk_with_overlap(text: str, chunk_size: int = 1000, overlap: int = 200) -> list[str]: + """Create overlapping chunks to preserve context across boundaries.""" + chunks = [] + start = 0 + + while start < len(text): + end = start + chunk_size + chunk = text[start:end] + chunks.append(chunk) + start += (chunk_size - overlap) # Overlap for context preservation + + return chunks + +# Example output: +# Chunk 1: "...the revenue grew by 3% over the previous quarter." +# Chunk 2: "...over the previous quarter. The company's EBITDA..." (overlap maintains context) +``` + +**Bad:** +```python +def chunk_without_overlap(text: str, chunk_size: int = 1000) -> list[str]: + """Split into fixed-size chunks with no overlap - loses boundary context.""" + return [text[i:i+chunk_size] for i in range(0, len(text), chunk_size)] + +# Example output: +# Chunk 1: "...the revenue grew by 3%" +# Chunk 2: "over the previous quarter..." (sentence split, context lost) +``` + +**Why It Matters:** Without overlap, important information spanning chunk boundaries becomes unretrievable. A query about "quarterly revenue growth" might miss the answer if "revenue grew by 3%" is in one chunk and "previous quarter" is in the next. Overlap ensures semantic units remain intact. + +### Example 2: Query-Context Integration + +**Good:** +```python +def create_rag_prompt(query: str, retrieved_docs: list[str]) -> str: + """Clearly separate context from query and instruct model behavior.""" + context = "\n\n".join([f"[Document {i+1}]\n{doc}" for i, doc in enumerate(retrieved_docs)]) + + return f"""Answer the following question based on the retrieved documents. If the documents don't contain sufficient information to answer, say so explicitly rather than guessing. + +Retrieved Documents: +{context} + +Question: {query} + +Answer:""" + +# Clear separation, explicit instructions, numbered sources +``` + +**Bad:** +```python +def create_rag_prompt_bad(query: str, retrieved_docs: list[str]) -> str: + """Unclear mixing of context and query.""" + return f"{' '.join(retrieved_docs)} {query}" + +# Context and query mashed together, no instructions, no source tracking +``` + +**Why It Matters:** Clear separation helps the model distinguish between query and context. Explicit instructions prevent hallucination when information is missing. Numbered sources enable citation and verification. Without this structure, models often ignore the retrieved context or fabricate answers. + +### Example 3: Embedding Model Selection + +**Good:** +```python +def embed_domain_specific(text: str, domain: str) -> list[float]: + """Use domain-appropriate embedding model for better retrieval.""" + # For code + if domain == "code": + model = "text-embedding-code-002" # Optimized for code + # For general text + elif domain == "general": + model = "text-embedding-ada-002" + # For multilingual + elif domain == "multilingual": + model = "multilingual-e5-large" + + response = client.embeddings.create(model=model, input=text) + return response.data[0].embedding +``` + +**Bad:** +```python +def embed_one_size_fits_all(text: str) -> list[float]: + """Always use the same embedding model regardless of content.""" + # Always uses ada-002, even for code or specialized domains + response = client.embeddings.create( + model="text-embedding-ada-002", + input=text + ) + return response.data[0].embedding +``` + +**Why It Matters:** General-purpose embedding models struggle with specialized content. Code embeddings understand syntax and semantics of programming languages. Domain-specific models capture terminology and relationships unique to that field. Using the wrong embedding model can result in 30-50% worse retrieval accuracy. + +### Example 4: Retrieval Evaluation + +**Good:** +```python +def evaluate_retrieval_quality(query: str, retrieved_docs: list[str], + ground_truth: str) -> dict: + """Measure both retrieval accuracy and generation faithfulness.""" + metrics = {} + + # Check if any retrieved doc contains ground truth + metrics['recall'] = any(ground_truth in doc for doc in retrieved_docs) + + # Measure semantic relevance + query_embedding = embed_text(query) + doc_embeddings = [embed_text(doc) for doc in retrieved_docs] + similarities = cosine_similarity([query_embedding], doc_embeddings)[0] + metrics['avg_similarity'] = similarities.mean() + metrics['top1_similarity'] = similarities.max() + + # Verify generation uses retrieved context + generated = generate_response(query, retrieved_docs) + metrics['uses_context'] = check_context_usage(generated, retrieved_docs) + + return metrics +``` + +**Bad:** +```python +def no_retrieval_evaluation(query: str, retrieved_docs: list[str]) -> str: + """Just generate without checking if retrieval was helpful.""" + return generate_response(query, retrieved_docs) + # No metrics, no verification, no way to improve system +``` + +**Why It Matters:** Without evaluation, you can't identify retrieval failures, tune chunk sizes, or optimize embedding models. Measuring recall, relevance, and context usage enables systematic improvement. Production RAG systems need continuous monitoring to detect when retrieval quality degrades. + +### Example 5: Handling Failed Retrieval + +**Good:** +```python +def robust_rag_query(query: str, documents: list[str], + relevance_threshold: float = 0.7) -> str: + """Gracefully handle cases where retrieval finds nothing relevant.""" + retrieved = retrieve_context(query, documents) + + # Check if retrieval was successful + if not retrieved or retrieval_confidence(query, retrieved) < relevance_threshold: + return { + "answer": "I don't have sufficient information in the knowledge base to answer this question accurately.", + "confidence": "low", + "retrieved_docs": [], + "recommendation": "Consider adding relevant documentation or rephrasing the query." + } + + # Generate with retrieved context + answer = generate_with_context(query, retrieved) + + return { + "answer": answer, + "confidence": "high", + "retrieved_docs": retrieved, + "sources": [doc['id'] for doc in retrieved] + } +``` + +**Bad:** +```python +def always_answer_rag(query: str, documents: list[str]) -> str: + """Force an answer even when retrieval fails.""" + retrieved = retrieve_context(query, documents) + + # Always generate, even with irrelevant or empty context + return generate_with_context(query, retrieved) + + # Result: hallucinated answer when nothing relevant was found +``` + +**Why It Matters:** When retrieval fails, forcing an answer leads to hallucination. Users receive confident-sounding but incorrect information, which is worse than admitting uncertainty. Checking retrieval quality and providing explicit "I don't know" responses maintains trust and helps identify gaps in the knowledge base. + +## Related Principles + +- **[Principle #46 - Context Window Engineering](46-context-window-engineering.md)** - RAG systems must carefully manage retrieved context to fit within model context windows. Chunking strategies and reranking help prioritize the most relevant information within token limits. + +- **[Principle #47 - Few-Shot Learning](47-few-shot-learning.md)** - RAG can be combined with few-shot prompting where retrieved examples serve as demonstrations. This hybrid approach grounds both the examples and the response in actual data. + +- **[Principle #48 - Chain-of-Thought Prompting](48-chain-of-thought.md)** - Multi-step reasoning in RAG benefits from CoT, where each reasoning step can trigger additional retrieval. Interleaving retrieval with CoT reasoning improves complex question answering. + +- **[Principle #51 - Agent Memory Systems](51-agent-memory.md)** - RAG serves as a form of long-term memory for agents, allowing them to recall relevant past experiences or knowledge when making decisions. The retrieval mechanism functions as memory recall. + +- **[Principle #31 - Idempotency by Design](31-idempotency-by-design.md)** - RAG queries should be idempotentβ€”running the same query multiple times should retrieve consistent information. This requires stable indexing and deterministic retrieval. + +- **[Principle #26 - Stateless by Default](26-stateless-by-default.md)** - RAG systems benefit from stateless retrieval where each query independently searches the knowledge base. This enables parallel queries and simplifies scaling. + +## Common Pitfalls + +1. **Chunking at Arbitrary Boundaries**: Splitting documents at fixed character counts without considering semantic units breaks sentences and paragraphs mid-thought, destroying context. + - Example: "The company's revenue grew by 3" in one chunk and "% in Q2 2023" in another. + - Impact: Queries about "Q2 2023 revenue growth" fail to retrieve the split information, resulting in incomplete or inaccurate answers. + +2. **Ignoring Chunk Overlap**: Without overlap between chunks, information at chunk boundaries becomes unretrievable when queries span those boundaries. + - Example: A 1000-token chunk ends with "The study concluded that" and the next chunk begins with "exercise reduces heart disease risk." + - Impact: A query about "study conclusions on heart disease" misses the relevant information because it's split across chunks. + +3. **Over-Retrieving Context**: Retrieving too many documents bloats the prompt with irrelevant information, confusing the model and wasting tokens. + - Example: Including 50 chunks totaling 20,000 tokens when only 3 chunks contain relevant information. + - Impact: Model struggles to identify key information, response quality degrades, costs increase 10x, and latency suffers. + +4. **Under-Retrieving Context**: Retrieving too few documents misses important information needed to fully answer the query. + - Example: Retrieving only the top 1 chunk when the complete answer requires synthesizing information from 3-4 related chunks. + - Impact: Partial or incomplete answers, especially for complex multi-aspect questions. + +5. **No Contextual Enrichment**: Embedding chunks without adding document-level context results in chunks that can't be understood in isolation. + - Example: A chunk saying "The company's revenue grew by 3%" without identifying which company or time period. + - Impact: 35-49% higher retrieval failure rate because chunks lack the semantic information needed to match relevant queries. + +6. **Semantic-Only Search**: Relying exclusively on embeddings misses exact matches for technical terms, error codes, or specific identifiers. + - Example: A query for "error code TS-999" might retrieve general error documentation instead of the specific TS-999 troubleshooting guide. + - Impact: Users get irrelevant results when they need exact technical information, especially in code documentation or technical support scenarios. + +7. **Stale Embeddings**: Not updating embeddings when documents change leads to the retrieval system working with outdated information. + - Example: Documentation is updated to reflect a new API endpoint, but the old version remains in the embedding index. + - Impact: RAG system retrieves and cites deprecated information, leading to incorrect usage of APIs or products. + +## Tools & Frameworks + +### RAG Frameworks & Libraries +- **LangChain**: Comprehensive framework for building RAG applications with built-in support for multiple retrievers, vector stores, and LLMs. Offers document loaders, text splitters, and chains for RAG workflows. +- **LlamaIndex**: Specialized framework for ingesting, structuring, and accessing private data with LLMs. Provides optimized indexing structures and query engines for RAG. +- **Haystack**: Production-ready framework by deepset with pipeline architecture for RAG.

Multi-Agent Orchestration + +## Plain-Language Definition + +Multi-agent orchestration is the coordination of multiple specialized AI agents working together to solve complex problems that exceed the capabilities of any single agent. Each agent has a specific role and expertise, and an orchestration layer manages how they communicate, share information, and combine their outputs to achieve a common goal. + +## Why This Matters for AI-First Development + +When AI agents build and modify systems, single-agent approaches quickly hit fundamental limits: context window constraints, single-perspective reasoning, inability to parallelize work, and lack of specialization. Multi-agent orchestration transforms these limitations into strengths by distributing work across specialized agents that can operate concurrently and independently. + +AI-first development with multiple agents provides three critical advantages: + +1. **Parallel exploration**: Multiple agents can simultaneously explore different solution paths, analyze various aspects of a problem, or process independent data streams. This parallelization dramatically reduces latency for complex tasks while improving coverage and reducing blind spots. + +2. **Specialization and expertise**: Agents can be optimized for specific domains, reasoning styles, or task types. A research agent uses different prompts and tools than a code generation agent or a validation agent. This specialization improves accuracy and reliability compared to generalist agents trying to handle all aspects of a task. + +3. **Emergent capabilities**: When agents collaborate, they create capabilities beyond what any individual agent possesses. A debate between multiple agents produces more nuanced analysis than a single agent's output. An orchestrator coordinating specialized workers can tackle problems that are too complex for sequential processing. + +Without orchestration, AI systems attempting complex tasks either fail completely or produce inconsistent, low-quality results. A single agent trying to research, reason, code, and validate will make mistakes that compound across the workflow. An uncoordinated group of agents will duplicate work, contradict each other, and fail to integrate their insights. Effective orchestration creates coherent, reliable systems from specialized components. + +## Implementation Approaches + +### 1. **Sequential Pipeline (Workflow Chaining)** + +Chain agents in a linear sequence where each agent processes the output of the previous one. This pattern trades latency for accuracy by making each step more focused and manageable. + +When to use: Tasks with clear dependencies where each step builds on the previous result.

This pattern maximizes throughput and enables diverse perspectives. + +When to use: Tasks that can be decomposed into independent subtasks, or when you need multiple perspectives on the same problem. Document analysis across many files, evaluating different aspects of a solution, or implementing guardrails where one agent processes content while another screens for issues. + +```python +class ParallelOrchestrator: + """Execute agents in parallel and merge results.""" + + def __init__( + self, + agents: List[Agent], + merger: ResultMerger, + max_concurrent: int = 5 + ): + self.agents = agents + self.merger = merger + self.semaphore = asyncio.Semaphore(max_concurrent) + + async def execute(self, input_data: Any) -> MergedResult: + async def run_agent(agent: Agent) -> AgentResult: + async with self.semaphore: + return await agent.process(input_data) + + # Execute all agents concurrently + tasks = [run_agent(agent) for agent in self.agents] + results = await asyncio.gather(*tasks, return_exceptions=True) + + # Separate successes from failures + successful = [r for r in results if not isinstance(r, Exception)] + failed = [r for r in results if isinstance(r, Exception)] + + # Merge successful results + merged = self.merger.merge(successful) + + return MergedResult( + output=merged, + success_count=len(successful), + failure_count=len(failed), + failures=failed + ) +``` + +### 3. **Hierarchical Orchestration (Manager-Worker)** + +A central orchestrator agent dynamically decomposes tasks, delegates to specialized worker agents, and synthesizes their outputs.

The bad example has no error handlingβ€”a single agent failure stops the entire pipeline, timeouts can hang indefinitely, and there's no visibility into what went wrong. In production, proper error handling is essential for reliability. + +## Related Principles + +- **[Principle #48 - Chain-of-Thought Reasoning](48-chain-of-thought-reasoning.md)** - Individual agents within orchestrated systems use chain-of-thought to break down their assigned subtasks. Orchestration operates at a higher level, coordinating multiple reasoning processes. + +- **[Principle #49 - Tool Use Patterns](49-tool-use-patterns.md)** - Agents within orchestrated systems use tools to interact with external systems. The orchestration layer manages tool availability, permissions, and result sharing between agents. + +- **[Principle #51 - Context Window Management](51-context-window-management.md)** - Multi-agent orchestration helps overcome context window limits by distributing work across agents, each with their own context window. This enables processing of arbitrarily large tasks. + +- **[Principle #13 - Parallel Exploration and Synthesis](../process/13-parallel-exploration-synthesis.md)** - Parallel agent execution is a form of parallel exploration. The orchestration layer implements the synthesis step, combining agent outputs into coherent results. + +- **[Principle #26 - Stateless by Default](26-stateless-by-default.md)** - Agents should be stateless when possible, with state managed by the orchestration layer. This makes agents more reliable, testable, and reusable across different orchestration patterns. + +- **[Principle #32 - Error Recovery Patterns](32-error-recovery-patterns.md)** - Orchestration layers must implement robust error recovery since failures can occur in any agent. Patterns include retries, fallbacks to alternative agents, and graceful degradation. + +## Common Pitfalls + +1. **Over-Engineering the Orchestration**: Adding complex orchestration when a single agent would suffice. Multi-agent systems add latency, cost, and potential points of failure. + - Example: Using three agents (planner, executor, validator) for a simple task like formatting text that a single agent handles perfectly. + - Impact: 3x the cost, 3x the latency, and potential consistency issues between agents. The complexity burden outweighs any benefit. + - Prevention: Start with single-agent solutions. Add orchestration only when you hit clear limitations: context window constraints, need for true parallelization, or demonstrable benefit from specialization. + +2. **Agents Without Clear Boundaries**: Agents with overlapping responsibilities that duplicate work or contradict each other. Unclear specialization defeats the purpose of orchestration. + - Example: Two agents both responsible for "analyzing code quality" with slightly different prompts, producing conflicting recommendations. + - Impact: Wasted computation, contradictory outputs, and inability to determine which agent's results to trust. Users receive confusing, inconsistent feedback. + - Prevention: Define clear, non-overlapping responsibilities for each agent. Document what each agent does and doesn't handle. Test agents individually before orchestrating them. + +3. **Ignoring Error Propagation**: Failing to handle errors at orchestration boundaries, allowing one agent's failure to cascade through the system. + - Example: Pipeline where the second agent expects structured data from the first agent, but no validation occurs. When the first agent returns an error message instead of data, the second agent crashes. + - Impact: Entire workflows fail instead of gracefully degrading. Debugging is difficult because the error location is obscured. Systems are fragile and unreliable. + - Prevention: Validate outputs between agents, implement retries and fallbacks, use circuit breakers for consistently failing agents, and maintain detailed execution logs. + +4. **Synchronous When Parallel Would Work**: Using sequential orchestration for tasks that could run in parallel, unnecessarily increasing latency. + - Example: Running three independent validation checks sequentially, taking 30 seconds total, when they could run in parallel in 10 seconds. + - Impact: User-facing latency is 3x higher than necessary, reducing responsiveness and user satisfaction. Resources sit idle while waiting for sequential completions. + - Prevention: Identify task dependencies explicitly. If tasks don't depend on each other's outputs, run them in parallel. Use profiling to identify sequential bottlenecks. + +5. **No Shared Memory Management**: Agents sharing state without proper synchronization, leading to race conditions and inconsistent results. + - Example: Multiple agents updating a shared findings dictionary concurrently without locks, causing lost updates and corrupted data structures. + - Impact: Intermittent bugs that are hard to reproduce, inconsistent results between runs, and data corruption that silently produces wrong answers. + - Prevention: Use proper synchronization primitives (locks, semaphores), provide read-only memory copies to agents, and design for message-passing rather than shared mutable state when possible. + +6. **Inadequate Agent Communication**: Agents passing insufficient context to each other, forcing downstream agents to re-derive information or make assumptions. + - Example: A research agent returns bullet points without preserving source citations, forcing the synthesis agent to guess which findings are most reliable. + - Impact: Loss of important context, inability to verify or trace back findings, degraded quality of downstream agent outputs, and reduced transparency. + - Prevention: Design explicit interfaces between agents. Include metadata (confidence scores, sources, reasoning). Validate that downstream agents receive everything they need. + +7. **Missing Feedback Loops**: No mechanism for agents to learn from results or adapt their behavior based on downstream feedback. + - Example: A code generation agent produces code that consistently fails validation checks, but never receives feedback about why or how to improve. + - Impact: Repeated mistakes that never get corrected, wasted computation on flawed approaches, inability to improve system performance over time. + - Prevention: Implement evaluator-optimizer patterns where appropriate, maintain execution histories, and use validator outputs to refine generator prompts or strategies. + +## Tools & Frameworks + +### Multi-Agent Orchestration Frameworks +- **[LangGraph](https://langchain-ai.github.io/langgraph/)**: Graph-based agent workflow orchestration with state management and checkpointing.

Single-agent solution inadequacy is documented. +- [ ] **Agent responsibilities are clearly defined**: Each agent has a single, well-documented purpose with clear inputs and outputs. No overlap or ambiguity. +- [ ] **Communication interfaces are explicit**: Data formats, error cases, and metadata requirements are specified at agent boundaries. +- [ ] **Parallel execution is used where possible**: Independent tasks run concurrently. Sequential dependencies are explicitly documented and justified. +- [ ] **Error handling covers all agent interactions**: Timeouts, retries, fallbacks, and graceful degradation are implemented at orchestration boundaries. +- [ ] **State management prevents race conditions**: Shared state uses proper synchronization.
