Can I use Hookify to prevent dangerous bash commands?

Yes, by setting the event type to 'bash' and providing a regex pattern like 'rm\s+-rf', you can configure Claude to warn you or block the command entirely.

Where should I store my Hookify rules?

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

How do I temporarily disable a rule?

You can temporarily disable any rule by setting the 'enabled' field in the YAML frontmatter to 'false' without having to delete the file.

Does Hookify support multiple matching conditions?

Yes, Hookify supports an advanced format where you can define multiple conditions using fields like file_path, new_text, and operators like contains or regex_match.

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. When a pattern matches a command or file edit, Claude displays a custom message or blocks the action.

Security & Testing

Simplifies the creation and configuration of custom guardrails and behavioral patterns for Claude Code using Hookify rules.

This skill provides expert guidance for writing Hookify rules, which are specialized markdown files designed to monitor and influence Claude's behavior during terminal operations, file edits, and task completion. By defining specific patterns and YAML frontmatter in `.claude` files, users can implement safety checks for dangerous bash commands, enforce coding standards during file operations, and establish mandatory checklists before an agent finishes a task. It is an essential tool for developers looking to automate policy enforcement and ensure consistent, safe interactions within their Claude-driven development environment.
