CLAUDE.md Writer
Helps create effective CLAUDE.md files that onboard Claude to a codebase without wasting context.
Core principle
More instructions hurt performance. Every line in CLAUDE.md is injected into every session, consuming the model's limited instruction budget. Write the minimum needed to cover what Claude cannot infer from the code itself.
A good CLAUDE.md answers exactly three questions:
| Dimension | Question |
|---|---|
| WHAT | What is this codebase? Tech stack, repo structure, key directories |
| WHY | What is its purpose? What do the major components do? |
| HOW | How does work get done? Build, test, lint commands; tooling quirks |
