description	Extract reusable patterns from the current session
user-invocable	true

/learn

Analyze the current session to extract reusable patterns, conventions, and lessons learned. Save them for future reference.

Arguments

• $ARGUMENTS — Optional focus area (e.g., "error handling", "testing patterns")

Process

1. Session Analysis

Review the current session for:

• Patterns that were applied repeatedly
• Conventions discovered in the codebase
• Solutions to problems encountered
• Anti-patterns that were corrected
• Architecture decisions made

2. Pattern Extraction

For each pattern found, document:

### Pattern: [Name]
**Context**: When to apply this pattern
**Solution**: What to do
**Example**: Code or command example
**Source**: Where this was learned (file, session context)

3. Categorization

Group patterns by type:

• Code Style: Naming, formatting, organization
• Architecture: Structure, dependencies, boundaries
• Testing: Test patterns, fixtures, assertions
• Error Handling: Exception patterns, recovery strategies
• Performance: Optimization techniques, caching
• Security: Validation patterns, auth patterns

4. Output

Save extracted patterns to the project's documentation or suggest additions to CLAUDE.md for the project.

Integration

Patterns can be promoted to:

• Rules (always-follow constraints)
• Skills (reusable workflows)
• CLAUDE.md entries (project conventions)
