Skill Claude CodeCodex
Write or update a data-dict.yaml documenting a dataset's tables, columns, types, constraints, relationships and glossary, then validate it against the real data. Use when starting work with a new or unfamiliar data source, or when asked to "document this dataset", "write a data dictionary", or "what is this column?".
Skill Claude CodeCodex
Orient yourself in a repository before changing anything: run the test suite, then read recent git history. Use at the start of a session in an unfamiliar project, or when asked to "get up to speed", "first run the tests", or "review recent changes".
Skill Claude CodeCodex
Use git as an investigative tool and author its history deliberately — recover lost work, bisect a regression, split and reword commits, prepare a reviewable PR. Use when asked about recent changes, when a bug "used to work", when git is in a mess, or before opening a pull request.
Skill Claude CodeCodex
Drive the real thing and prove it works — interpreter one-liners, curl against a dev server, a browser, a screenshot. Use before claiming any change works, when asked to "test it by hand", "check it actually works", or "show me it working".
Skill Claude CodeCodex
Decide whether to delegate work to subagents, and write a subagent prompt that actually works. Use when a task spans many files or requires reading far more than the answer is worth, or when asked to "use subagents" or "search in parallel".
Skill Claude CodeCodex
Red/green test-driven development. Write the test first, watch it fail, then make it pass. Use when adding a feature, fixing a bug, or whenever the user says "use red/green TDD", "write tests first", or reports something broken.
Skill Claude CodeCodex
Produce a linear, top-to-bottom explanation of how a piece of code actually works, with code snippets read from disk rather than retyped. Use when asked to "explain this code", "give me a walkthrough", "how does this work", or when onboarding onto an unfamiliar module.
