+# Cron Automation Scripts
+
+This directory contains dev-local cron automation scripts for agentic quality control and CI/CD monitoring.
+
+## Scripts
+
+### `nightly-ci-check.ts`
+
+**Purpose**: Automated nightly CI health check and fix attempt
+
+**Requirements**: 
+- Node.js with `tsx` for TypeScript execution
+- GitHub CLI (`gh`) authenticated
+- Claude Code CLI (`claude`) 
+- Git 2.5+ with worktree support
+
+**Schedule**: Runs at 2:00 AM daily via cron
+
+**Workflow**:
+1. Checks recent GitHub workflow runs using GitHub CLI
+2. Filters for scheduled workflows with unresolved failures/cancellations
+3. For each failure, creates a dedicated worktree using `nt` command
+4. Collects failure data: logs, metadata, commit ranges, PR information
+5. Invokes Claude Code for root cause analysis in isolated worktree
+6. Generates assessment reports and attempts fixes based on confidence level
