What are Hookify rules in Claude Code?

Hookify rules are specialized markdown files with YAML frontmatter that define patterns for Claude to watch. When a pattern matches a bash command or file edit, Claude displays a custom message or blocks the action.

What events can I trigger rules on?

You can trigger rules on bash (terminal commands), file (edits and writes), stop (when the session ends), and prompt (user input) events.

Where are Hookify rules stored?

Rules must be stored in the .claude/ directory of your project root using the naming convention .claude/hookify.{rule-name}.local.md.

Can Hookify rules prevent specific actions?

Yes, by using the 'action: block' field in the frontmatter, you can prevent Claude from executing specific terminal commands or writing prohibited code patterns.

Do I need to restart Claude to apply new rules?

No, rules are read dynamically. Any changes made to a .local.md file in the .claude directory take effect on the next tool use.
