What you get
About this skill
What it does
Secret Leak Guard provides a high-performance, local-first scanning layer to prevent credentials, API keys, and sensitive tokens from ever leaving your machine. It identifies high-entropy strings and known secret patterns within your codebase before they are pushed to remote repositories.
Why use this skill
Relying on generic LLM prompts for security is risky; they can miss subtle patterns or fail to prioritize leaked data correctly. This skill automates the detection process with precision, providing masked findings to ensure the AI agent itself doesn't inadvertently log the full secret. It is essential for maintaining compliance and preventing 0-day credential leaks.
Supported Environment
- Works across any local directory or Git repository
- Supports modern development environments like Cursor, Claude Code, and VS Code
- Optional JSON output for integration into CI/CD pipelines or custom developer workflows
- Zero network calls for scanning, ensuring complete data privacy
The Output
You receive a clean, actionable report of potential leaks, categorized by file and line number, with sensitive values safely masked for review.
How to install
Drop the file into your AI Agent. Works with Claude, Cursor, ChatGPT, and 20+ more.
