Hook Creator

Create Claude Code hooks that execute shell commands at specific lifecycle events.

Hook Creation Workflow

1. Identify the use case - Determine what the hook should accomplish
2. Select the appropriate event - Choose from available hook events (see references/hook-events.md)
3. Design the hook command - Write shell command that processes JSON input from stdin
4. Configure the matcher - Set tool/event filter (use * for all, or specific tool names like Bash, Edit|Write)
5. Choose storage location - User settings (~/.claude/settings.json) or project (.claude/settings.json)
6. Test the hook - Verify behavior with a simple test case
