Frequently asked
About hooks
What are Claude Code hooks?+
Hooks are user-defined scripts that run on Claude Code lifecycle events — PreToolUse, PostToolUse, Stop, Notification, and others. They let you add permission gates, audit logs, or custom behavior without modifying the agent loop.
What can a hook do?+
Hooks receive event metadata via stdin and can approve, deny, or modify tool calls. Common uses: blocking writes to sensitive files, logging tool usage, sending notifications when Claude is waiting for input.
How do I configure a Claude Code hook?+
Add an entry under hooks in your settings.json with the matching event and the command to run. The command is invoked synchronously and can return a JSON decision.
