+# Experimental Features
+
+## What are Experimental Features?
+
+Experimental features in Strands Agents are cutting-edge capabilities that are:
+- In active development and testing
+- Subject to breaking changes
+- Available for early feedback and evaluation
+- Not recommended for production use without careful consideration
+
+## Current Experimental Features
+
+### Configuration Loaders
+Declarative configuration for agents, tools, swarms, and graphs with comprehensive schema validation and IDE integration support.
+
+**Key Features:**
+- **Schema Validation**: Comprehensive JSON Schema validation with IDE integration
+- **IDE Support**: VSCode, IntelliJ, Vim autocompletion and real-time validation
+- **Type Safety**: Enforced structure and types without restrictive constraints
+- **Nested Configurations**: Support for agents-as-tools, graphs-as-tools, swarms-as-tools
+- **Error Prevention**: Catch configuration errors before runtime
+
+**Configuration Types:**
+- **Agent Configuration**: Single agents with tools, structured output, and advanced features
+- **Graph Configuration**: Multi-agent workflows with nodes, edges, and conditions
+- **Swarm Configuration**: Collaborative agent teams with autonomous coordination
+- **Tool Configuration**: Standalone tool definitions and agent-as-tool patterns
+
+## Using Experimental Features
+
+### Installation
+```bash
+# Experimental features are included in the main SDK
+pip install strands-agents
+```
+
+### Enabling Experimental Features
+```python
+from strands.experimental.config_loader import AgentConfigLoader
+
+# All configurations require top-level keys for schema validation
+config = {
+    "agent": {
+        "model": "us.amazon.nova-pro-v1:0",
+        "system_prompt": "You are a helpful assistant.",
+        "tools": [{"name": "calculator"}]
+    }
+}
+
+loader = AgentConfigLoader()
+agent = loader.load_agent(config)
+```
+
+### IDE Integration Setup
+
+**Global VSCode Settings:**
+```json
+{
+  "yaml.schemas": {
+    "https://strandsagents.com/schemas/config/v1": "*.strands.yml"
+  }
+}
+```
+

+                "agent": {
+                    "model": "us.amazon.nova-lite-v1:0",
+                    "system_prompt": "Research: {topic}"
+                },
+                "input_schema": {
