Which events can trigger a Hookify rule?

Rules can be triggered by 'bash' commands, 'file' edits (writes/edits), 'stop' events (when the agent finishes), and 'prompt' events (user input).

Where should I store my Hookify rule files?

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

Can I prevent Claude from running specific commands?

Yes, by setting the 'action' field to 'block' in the rule's frontmatter, you can stop Claude from executing matched bash commands or file operations.

What is a Hookify rule in Claude Code?

A Hookify rule is a markdown file with YAML frontmatter stored in the .claude directory that defines patterns for Claude to watch and specific messages to display when those patterns are matched.

How do I test my Hookify regex patterns?

You can test patterns using Python's regex engine via the terminal or online tools like regex101.com using the Python flavor.
