 ## Key Patterns
 
+### Agent Behavior Patterns
+
+How AI agents work during development:
+
+- **[Self-Review Reflection](docs/patterns/self-review-reflection.md)** - Agent reviews own work before presenting to humans
+- **[Autonomous Quality Enforcement](docs/patterns/autonomous-quality-enforcement.md)** - Validate code before presenting
+- **[Multi-Agent Code Review](docs/patterns/multi-agent-code-review.md)** - Parallel specialized reviews
+
+### GHA Automation Patterns
+
+Proactive CI/CD workflows in [`docs/patterns/gha-automation-patterns.md`](docs/patterns/gha-automation-patterns.md):
+
+- **Issue-to-PR Automation** - Convert issues to draft PRs automatically
+- **PR Auto-Review** - AI code review on every PR
+- **Dependabot Auto-Merge** - Safe auto-merge for patch updates
+- **Stale Issue Management** - Cleanup inactive issues
