tuyv Claude Code Hook Builder
Create Claude Code hooks that are narrow, testable, and fail safely around tool-use or session events.
Fast Workflow
- Clarify the hook event, matcher, intended decision, expected side effects, and failure behavior before writing code.
- Prefer small deterministic scripts over broad prompt-based checks for security-sensitive validation.
- Keep hooks scoped to the project unless the user explicitly wants user-wide behavior.
- Test hook scripts directly with representative JSON payloads before wiring them into settings.
Detailed Reference
Read references/full-guide.md when you need hook event payloads, matcher examples, validation scripts, settings snippets, and troubleshooting guidance. Keep this entrypoint loaded first, then load only the reference sections relevant to the task.
Documentation
Read current Claude Code hook docs when event payload or permission semantics matter.
Output
Give concrete file paths, commands, validation steps, and any restart/reload requirement. Avoid broad rewrites when a small generated file or setting is enough.
