Update Claude Md

After every correction the user gives you, do the following:

Steps

1. Identify the mistake pattern — What went wrong? What should have been done instead? Be specific.

1. Write a rule — Formulate it as a clear, actionable rule that prevents this class of mistake. Lead with the rule, then add context if needed.

1. Update CLAUDE.md — Append the rule to the relevant CLAUDE.md (project-level if in a project, global ~/.claude/CLAUDE.md if it's a general behavior). Add it under a "Corrections" or "Rules" section.

1. Confirm — Tell the user: "Updated CLAUDE.md with: [rule summary]"

Principles

• After EVERY correction, end the session with: "Update your CLAUDE.md so you don't make that mistake again."
• Ruthlessly edit CLAUDE.md over time — if a rule isn't reducing mistakes, rewrite it
• If the project has a /memory or tasks/ notes directory, update it there too and point CLAUDE.md at it
• Claude is eerily good at writing rules for itself — trust the process

Rule Format

## Rules / Corrections

- [Rule]: [What to do / not do]. [Why: brief context from the mistake]

Example

User: "Stop wrapping every response with a summary of what you just did."

Claude updates CLAUDE.md:

- No trailing summaries: Do not summarize actions at the end of responses. The user can read the diff.
