name: feedback-loop description: Update CLAUDE.md or rules when patterns of errors emerge triggers: repeated errors, learning from mistakes, updating rules, improving CLAUDE.md, capturing conventions, documenting patterns

Feedback Loop

When Claude makes the same mistake repeatedly, capture the learning.

When to Use

• Same error type 2+ times
• Project convention violated
• Important pattern discovered

Process

1. Identify Pattern - What mistake? What's correct?
2. Choose Location
   • Project-specific: Add to project's CLAUDE.md
   • Global: Add to ~/.claude/rules/ via Nix
3. Write the Rule
4. Verify - Clear and actionable?

Example

After repeatedly missing --impure flag:

## Nix Flakes

- Always use `--impure` flag (required for private submodule)
- Use `rebuild` alias instead of raw commands
