What is a Hookify rule?

A Hookify rule is a specialized markdown file with YAML frontmatter that defines patterns Claude should watch for and specific messages to display when those patterns are matched.

What events can trigger a Hookify rule?

Rules can be triggered by bash commands, file edits (Edit, Write, MultiEdit tools), when the agent is about to stop, or when a user submits a prompt.

Can Hookify prevent dangerous commands from running?

Yes, by using the 'block' action in the rule's frontmatter, you can prevent specific bash commands or file edits from being executed.

Where should I store Hookify rules?

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