Adds security scanning via PreToolUse hooks + refactoring commands: - PreToolUse hook catches security issues before code is written - /security-scan command for comprehensive security audit - /refactor command to apply refactoring patterns - /refactor-dry command to preview refactoring opportunities - security-reviewer agent for vulnerability analysis - refactor-advisor agent for code structure improvements - security-patterns skill for vulnerability detection rules Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Process
-
Analyze Target
- Parse code structure
- Identify refactoring opportunities
- Check for side effects and dependencies
-
Propose Changes
- Show before/after diff
- Explain the improvement
- List affected files/references
-
Apply (with confirmation)
- Make changes
- Update all references
- Run existing tests if available
-
Output
## Refactoring: extract-method
### Target
src/handlers.py:create_order (lines 45-89)
### Changes
- Extracted validation logic → validate_order_input()
- Extracted pricing logic → calculate_order_total()
- Original function now 15 lines (was 44)
### Files Modified
- src/handlers.py
- tests/test_handlers.py (updated calls)
### Metrics
- Cyclomatic complexity: 12 → 4
- Function length: 44 → 15 lines
