Will this skill run dangerous commands like 'rm -rf'?

No. The system categorizes commands into Safe, Conditional, and Dangerous tiers. Dangerous commands are automatically skipped, and Conditional commands require explicit user approval before execution.

How does the caching system work with Git?

The skill tracks the git commit hash of the last validation. On subsequent runs, it uses git diff to identify changed files and only re-validates commands affected by those specific changes, ensuring high performance.

What happens if a command in my documentation is wrong?

The skill provides a detailed report showing the exact file and line number of the failure, the error message received, and offers to update your knowledge base if the CLI name was simply misinterpreted.

Can I use this for non-JavaScript projects?

Yes, while optimized for modern JS/Node.js environments, it supports multiple command types including Python, Cargo, Docker, Git, and generic shell operations.

Does using this skill cost extra LLM tokens?

After the initial discovery and setup phase, the skill is designed for zero-token operation by relying on local bash execution and deterministic caching logic.

Learning & Documentation

Validates commands within markdown documentation using intelligent git-aware caching to ensure accuracy with zero token overhead.

Command Verify is a specialized skill designed to maintain the integrity of project documentation by automatically discovering and testing commands found in markdown files. By leveraging a git diff-based caching system, the skill identifies which commands need revalidation based on recent file changes, achieving a 90%+ cache hit rate and minimizing execution time. It includes a sophisticated safety categorization system that prevents the execution of dangerous commands while utilizing a self-learning memory system to adapt to project-specific CLI naming and validation rules, making it an essential tool for maintaining high-quality technical documentation.

Key Features

01Git diff-based intelligent cache invalidation for high-speed, zero-token operation
