How do I block Claude from writing bad code?

By using exit code 2 in your hook script, you can block the current action and send the error output back to Claude so it can fix the issue automatically.

Where should I store my hook configurations?

Hooks should be configured in the .claude/settings.json file to ensure they are shared with your team via version control, rather than settings.local.json.

What is a Claude Code hook?

A hook is a specialized script that runs during specific events, such as before or after a tool is used, to validate, modify, or block Claude's actions based on predefined rules.

Are these hooks cross-platform?

Yes, by wrapping shell commands in Python scripts as recommended by this skill, hooks remain compatible across different operating systems like macOS, Linux, and Windows.

Will running hooks slow down my development process?

This skill follows the 'Fast checks only' principle, recommending that hooks run in under 5 seconds to maintain a smooth and responsive developer experience.

개발자 도구

Automates the creation of Claude Code hooks for real-time linting, formatting, and type-checking during the development process.

소개

The write-hook skill empowers developers to establish robust quality gates within their Claude Code workflow by generating custom, Python-based hooks. It provides a standardized framework for enforcing project-specific coding standards—such as ESLint, Prettier, and TypeScript checks—ensuring that AI-generated code meets production requirements before it is finalized. By leveraging blocking exit codes and structured JSON communication, this skill allows for seamless integration of static analysis tools, preventing regressions and maintaining high-quality codebases through automated validation and auto-fixing capabilities.
