Ccguard — Development skill for Claude Code

🚨 CCGuard

[](https://www.npmjs.com/package/ccguard) [](LICENSE)

**Automated enforcement of net-negative LOC, complexity constraints, and quality standards for Claude code**

📌 **New in v0.1.4**: The [Snapshot Strategy](#snapshot-strategy-recommended-as-of-v014) is now the recommended approach for more robust session-wide LOC tracking.

🔒 **New**: File locking feature to protect critical files from any modifications.

🎯 Overview

**CCGuard** ensures your codebase stays lean by blocking changes that exceed your configured line count threshold during Claude coding sessions. By default, it enforces net-negative changes (no increase allowed), but can be configured with a positive lines buffer for flexibility. It encourages simplicity, thoughtful refactoring, and a cleaner, maintainable codebase.
