Where should I store my Hookify rules?

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

Can Hookify rules prevent Claude from running dangerous commands?

Yes, by setting the action to 'block' and targetting the 'bash' event, you can stop Claude from executing specific command patterns like 'rm -rf'.

How do I test if my regex pattern is correct for a rule?

You can test patterns using a Python regex script: python3 -c "import re; print(re.search(r'pattern', 'test text'))" or use online testers with Python flavor support.

What is a Hookify rule?

A Hookify rule is a markdown file with YAML frontmatter that defines specific patterns to watch for and messages to display when Claude Code interacts with your files or terminal.

Do I need to restart my session to apply rule changes?

No, Hookify rules are read dynamically and changes take effect as soon as you save the rule file and Claude uses a tool.

Developer Tools

Automates the creation and configuration of custom governance rules to monitor, warn, or block specific patterns in Claude Code workflows.

The Hookify Rule Writing skill provides a structured framework for defining custom guardrails and behavioral patterns within the Claude Code environment. By leveraging YAML frontmatter and regex-based triggers, it allows developers to intercept bash commands, file edits, and session completions to enforce coding standards, prevent dangerous operations like 'rm -rf', and ensure critical tasks like testing or documentation are performed. This skill is essential for teams and solo developers who want to standardize AI-assisted development through project-specific linting and real-time behavioral guidance.
