Claude hooks enable you to register PostToolUse events that automatically run formatters like prettier on edited files. Configure a hook in .claude/hooks to execute formatting commands after each file modification, ensuring consistent code style without manual intervention.

Claude hooks are shell commands triggered at specific lifecycle events—PreToolUse, PostToolUse, UserPromptSubmit, and others—allowing you to automate tasks, enforce standards, log activity, and customize Claude's behavior deterministically across your projects.

Create a PreToolUse hook in your .claude/hooks folder with a shell script that captures and logs Bash commands to a file. The hook executes before each tool use, recording all commands Claude runs for audit and debugging purposes.

Yes. Configure a PreToolUse hook that evaluates file paths and blocks edits to sensitive files by returning a non-zero exit code. Hooks support access control logic to protect restricted files before Claude applies changes.

The claude-hooks-manager skill requires jq for JSON processing of hook configurations. Shell scripting knowledge is needed to write hook commands; no additional runtime dependencies are required beyond a standard shell environment.

Nine hook events are supported: PreToolUse, PostToolUse, UserPromptSubmit, Notification, Stop, SubagentStop, PreCompact, SessionStart, and SessionEnd. Each event fires at a specific point in Claude's lifecycle, enabling precise automation and monitoring.
