Can I prevent Claude from running specific commands?

Yes, by setting the 'action' field to 'block' in the rule's frontmatter, you can prevent Claude from executing specific bash commands or performing certain file operations.

What is a Hookify rule in Claude Code?

A Hookify rule is a markdown file with YAML configuration that allows you to define patterns to watch for during a Claude Code session, triggering specific messages, warnings, or blocks when matched.

What types of events can trigger a Hookify rule?

Rules can be triggered by bash commands (bash), file modifications (file), when Claude finishes a task (stop), or specific keywords in a user's prompt (prompt).

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

You can test patterns using a Python regex tester or online tools like regex101.com (Python flavor). Alternatively, rules are dynamic, so you can test them immediately within Claude Code after saving the file.

Where should I store my Hookify rules?

Rules are stored in the '.claude/' directory of your project using the naming convention 'hookify.{rule-name}.local.md'. It is recommended to add these to your gitignore.

Productivity & Workflow

Configures custom guardrails and automation rules to intercept and guide Claude's behavior during CLI sessions.

About

This skill empowers users to define sophisticated project-specific rules that monitor Claude's activities, such as executing dangerous bash commands or editing sensitive files. By leveraging Hookify rules with regex patterns and YAML frontmatter, developers can enforce coding standards, prevent security risks like hardcoded API keys, and establish mandatory pre-completion checklists. This ensures Claude operates within the specific safety, security, and style parameters of any codebase, providing a robust layer of automated oversight for AI-driven development.

Key Features

Intercepts dangerous bash commands like 'rm -rf' or 'sudo' with custom warnings
Monitors file edits for sensitive data or problematic patterns like 'console.log'
Supports advanced multi-condition logic using regex, substring, and prefix matching
12,827 GitHub stars
Dynamic rule loading from the .claude/ directory without requiring session restarts
Enforces project-specific workflows with mandatory stop-event checklists

Use Cases

Creating automated deployment or PR checklists that Claude must verify before completing a task
Preventing accidental deletion of critical system files or production data during CLI tasks
Enforcing coding standards by flagging debug statements or insecure functions before they are committed
