Where are Hookify rules stored?

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

What events can trigger a Hookify rule?

Hookify rules can be triggered by four main events: 'bash' for terminal commands, 'file' for code edits, 'stop' for session completions, and 'prompt' for user input.

How do I update or disable a rule?

You can update a rule by editing its .md file; changes take effect immediately on the next tool use. To disable a rule, set 'enabled: false' in the YAML frontmatter or delete the file.

What is a Hookify rule?

A Hookify rule is a configuration file in the .claude directory that allows you to trigger custom messages or blocks when Claude performs specific actions like running a command or editing a file.

Can I prevent Claude from running dangerous commands?

Yes, by setting the 'action' field to 'block' in your rule's frontmatter, you can force Claude to stop a command or session when a specific pattern is matched.

개발자 도구

Configures custom guardrails and automated interventions for Claude Code by defining patterns for shell commands and file modifications.

This skill provides Claude with the specialized knowledge to create, refine, and implement Hookify rules—project-specific guardrails stored as Markdown files with YAML frontmatter. It enables the creation of automated warnings or blocks for dangerous shell commands (like 'rm -rf'), sensitive file edits (like .env changes), and completion checklists. By leveraging regex patterns and multi-condition logic, this skill ensures that AI-driven development remains safe, compliant, and aligned with team-specific best practices without manual oversight.
