What is a Hookify rule?

A Hookify rule is a specialized markdown file with YAML frontmatter that defines specific patterns to watch for and custom messages to display when Claude matches those patterns during a session.

Can I prevent Claude from running specific commands?

Yes, by setting the action field to 'block' in the YAML frontmatter, you can force the rule to prevent a command from executing if the pattern matches.

What event types are supported?

Hookify supports bash (terminal commands), file (edits/writes), stop (task completion), prompt (user input), and all (every event).

Do I need to restart Claude for rules to take effect?

No, rules are read dynamically. Any changes to your .local.md files take effect immediately on the next tool use or event trigger.

Where are Hookify rules stored?

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

Herramientas para Desarrolladores

Configures automated guardrails and custom workflow rules to guide Claude's behavior during terminal commands and file operations.

Writing Hookify Rules empowers developers to create specialized markdown-based triggers that monitor Claude's actions in real-time within the terminal. By defining regex patterns for bash commands, file edits, and session events, users can implement custom warnings, block dangerous operations like unauthorized recursive deletions, and enforce coding standards or security best practices. This skill provides the precise syntax, condition logic, and implementation patterns necessary to build a robust local governance layer for AI-driven development workflows.
