Where should I store my Hookify rules?

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

What is a Hookify rule in Claude Code?

A Hookify rule is a specialized markdown file with YAML metadata that instructs Claude Code to monitor specific patterns and provide contextual feedback or block operations.

Can I prevent Claude from running specific shell commands?

Yes, by setting the event to 'bash' and the action to 'block', you can use regex patterns to intercept and stop dangerous commands before they execute.

How do I test if my Hookify regex pattern works?

You can test patterns using a Python one-liner in the terminal: python3 -c "import re; print(re.search(r'your_pattern', 'test text'))" or use an online Python-flavor regex tester.

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

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