What is a Hookify rule?

A Hookify rule is a Markdown file stored in the .claude/ directory that uses YAML frontmatter to define patterns. When Claude matches these patterns in commands or files, it triggers a custom message or action.

How do I name a new Hookify rule file?

Rules should follow the naming convention .claude/hookify.{rule-name}.local.md to be correctly recognized by the system.

Can I prevent Claude from running specific commands?

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

What is the difference between bash and file events?

Bash events trigger when Claude attempts to run a terminal command, while file events trigger during Edit, Write, or MultiEdit operations on project files.

Do I need to restart the session for rules to take effect?

No, Hookify rules are read dynamically and take effect on the very next tool use after the rule file is saved or modified.
