Hooks
Shell scripts that run automatically before or after Claude Code uses a tool. Use hooks to auto-format code, enforce linting, block risky file edits, run tests, or send notifications — all without manual intervention. Supports PreToolUse, PostToolUse, Notification, and Stop events. Each hook below includes a ready-to-use script and configuration.
