# Mistake to constraint

A repeated mistake is an environment bug. Do not add another prompt paragraph first.

## Order (strongest first)

1. **Type narrowing or runtime guard** — make the illegal state unrepresentable. See `templates/runtime-guard.py`.
2. **Lint rule** — copy `templates/eslint-rule.cjs` or `templates/semgrep-rule.yml`. Prefer an existing ruff selector from `templates/ruff-snippet.toml` before a new plugin.
