name: hooks-management description: Use PROACTIVELY when you need to create, update, configure, or validate Claude hooks for various events and integrations

Goal: Create, update or troubleshoot Claude Code hook scripts

Workflow

Phase 1: Exploration & Analysis

• T001: Read hook docs from .claude/skills/hooks-management/references/hooks.md
• T002: Analyze the request and identify if the task is to create, update or troubleshoot a hook.
• T003: Choose the appropriate task to perform based on the request in .claude/skills/hooks-management/tasks/
• T004: Check existing hooks in .claude/hooks/ and settings configuration in .claude/settings.local.json
• T005: Perform the task
• T006: Test the hook execution and edge cases using echo (see Testing Strategy)
• T007: Review security and performance
• T008: Update .claude/skills/hooks-management/references/hooks-status.md to reflect changes
• T009: Update .claude/skills/hooks-management/references/architecture-pattern.md if architectural changes were made (new modules, utils, patterns)
• T010: Provide comprehensive report to main agent

Implementation Strategy

• For new hooks: Create script file in .claude/hooks/ following naming convention
• If the task is to troubleshoot, follow the troubleshooting task in .claude/skills/hooks-management/tasks/troubleshooting.md
• If the task is to update, follow the update task in .claude/skills/hooks-management/tasks/update-hook.md
• If the task is to create, follow the create task in .claude/skills/hooks-management/tasks/create-new-hook.md
• Prefer Python over shell scripts if possible.
• Implement idempotent operations where possible

Testing Strategy

Use echo to pipe test input directly to hook scripts without creating test files:

Copy# Test with sample JSON input
echo '{"session_id": "test-123", "tool": "Read", "result": "sample output"}' | python .claude/hooks/your-hook.py

# Test with minimal input
echo '{}' | python .claude/hooks/your-hook.py

# Test error handling with malformed input
echo 'invalid json' | python .claude/hooks/your-hook.py

# Test with specific event data
echo '{"event": "stop", "reason": "user_request"}' | python .claude/hooks/your-hook.py

Testing Checklist:

• Hook accepts valid JSON input via stdin
• Hook handles empty input gracefully
• Hook handles malformed input without crashing
• Hook returns appropriate exit codes (0 for success, non-zero for errors)
• Hook output is valid JSON when required by the event type

Constraints

• Must update .claude/settings.local.json to link hooks
• Must test hooks after generation without creating test files
• Never create hooks that modify critical system files
• Never implement hooks with hardcoded credentials
• Never write hooks that can cause infinite loops
• Never bypass security validations or access controls
• Never create hooks without proper error handling
• Never create test files when testing hooks
• Never write complicated hooks with complex logic. Keep it simple and straightforward.

Success Criteria

• Hook script exists and is syntactically valid
• Hook is properly linked in settings.local.json
• Hook executes successfully on target event
• Error handling covers common failure scenarios
• No security vulnerabilities detected
• hooks-status.md reference updated to reflect current hook state
• architecture-pattern.md updated if architectural changes were made
• Comprehensive report provided to main agent upon completion
• Code is readable and concise.
