What are the 7 Key Principles this skill validates?

The skill checks for Test Driven Development (TDD), Fail Fast mechanisms, Modular/Maintainable architecture, Reuse Before Build, Open Source First, No Legacy Baggage (debt), and Perfectionist Excellence.

Does it work with any programming language?

While the principles are universal, the default validation checks are optimized for Python and common shell utilities like Grep and Bash.

Can this skill fix the issues it finds automatically?

This skill primarily acts as a validator and sensor. It identifies violations and provides recommended actions, such as invoking specific pruning or simplification tools to remediate the code.

How does it verify Principle #6 (No Legacy Baggage)?

It scans for unused imports, dead functions with zero callers, commented-out code blocks, and 'TODO' comments that lack associated tracking tickets.

What metrics does it use for 'Modular' code?

It checks for file lengths under 300 lines, function lengths under 50 lines, and a cyclomatic complexity score of 10 or less.

Security & Testing

Validates and enforces seven core engineering principles to ensure code quality, test coverage, and architectural integrity.

The Apply Key Principles skill is a sophisticated code validator designed to automate the enforcement of high-standard software development lifecycles. It systematically audits codebases against seven critical pillars: Test Driven Development, Fail-Fast mechanisms, modular architecture, code reuse, open-source adoption, technical debt elimination, and stylistic excellence. By running automated checks for test coverage, cyclomatic complexity, and naming conventions, it serves as a rigorous quality gate during refactoring or code reviews, ensuring that every commit meets perfectionist standards and remains maintainable over time.

Key Features

01Structural analysis of file size and cyclomatic complexity

02Technical debt identification including dead code and unused imports

03Detection of silent failures and deferred error handling

04Stylistic audit for naming quality, docstrings, and type hints

050 GitHub stars

06Automated TDD compliance and test coverage verification

Use Cases

01Scanning legacy codebases to identify and prioritize technical debt refactoring

02Automating code reviews to catch architectural violations before human intervention

03Maintaining high-quality engineering standards in complex AI-assisted development
