-## Using AI Tools
-
-AI-assisted contributions are welcome. But please **review the output before opening a PR**:
-
-1. **Review the code** — understand what was generated, don't just commit blindly
-2. **Write a PR description** — explain what changed and why
-3. **Rebase on latest `main`** — AI tools often work on stale branches, run `git rebase origin/main` before pushing
-4. **Clean up artifacts** — remove IDE configs (`.idea/`, `.kiro/`), env files, scratch notes, and throwaway test scripts that AI tools leave behind
