How to Write a CLAUDE.md File That Actually Helps Your Team

A good CLAUDE.md is short, actionable, and specific to the repository. Include how the application is structured, how to run it, how to test it, important conventions, and rules the agent must not break.

Avoid documenting obvious information that changes constantly. Put durable engineering decisions in the project file and link to deeper documentation when necessary. Ask Claude to read the instructions before planning a task.

Review the file periodically. If developers repeatedly correct the same mistake, that is a signal that the project briefing needs improvement.

Practical takeaway: Use Claude to reduce repetitive work while keeping human judgment for accuracy, privacy, security, and important decisions.
