Where are Hookify rules stored?

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

Do I need to restart my session to apply new rules?

No, Hookify rules are read dynamically and take effect immediately on the very next tool use or command execution.

What is the difference between a 'warn' and 'block' action?

A 'warn' action shows a message to Claude but allows the operation to proceed, while a 'block' action prevents the tool from executing or stops the session entirely.

Can I block specific file edits or patterns?

Yes, by using the 'file' event and specifying conditions for file_path or new_text, you can prevent patterns like console.log or unauthorized edits to sensitive files.

What is a Hookify rule in Claude Code?

A Hookify rule is a markdown file with YAML frontmatter that defines specific patterns for Claude to watch for, triggering warnings or blocking actions when matches occur.
