Generate, audit, or improve a project README following a 15-section structure (Title, Table of Contents, About, Features, Tech Stack, Architecture, Project Structure, Getting Started, Configuration, Security, How to Contribute, What's Next, License, Acknowledgements, Author) with Mermaid diagrams for architecture and flows. Use this skill whenever the user asks to "write a README", "create a README", "draft a README", "generate README.md", "scaffold project docs", "document this repo", "improve my README", "audit my README", "what should go in my README", or starts a new repository and needs documentation. Also trigger on phrases like "the README is bare", "this project has no docs", "fill in my README sections", or any request that produces or reviews a top-level repository README. The skill defaults to Mermaid for diagrams because it renders natively on GitHub, GitLab, Bitbucket, and most modern Markdown viewers — no external image hosting required.
Write, extend, or review tests in any codebase. Use this skill whenever the user asks to write tests, add test coverage, test a new feature, fix failing tests, or audit existing test files — regardless of language, framework, or project. Also trigger for "add tests for", "write tests for", "cover this with tests", "test this file", "update the tests", "improve coverage", or "this needs tests". This skill enforces universal testing rules (no .skip, no lowering thresholds, full-path coverage) and adapts its mock patterns and tooling to whatever stack the repo uses.
Use this skill whenever you need to commit changes or generate a conventional commit message for user review.
