description	After any correction from the user, update CLAUDE.md with a rule to prevent the same mistake from recurring. Use when the user corrects your behavior or says "don't do that again". Ruthlessly iterate CLAUDE.md until mistake rate measurably drops.

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.

2. 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.

3. 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.

4. 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.
