+# AI Contributor Code of Conduct
+
+These rules apply to **any AI agent or AI-assisted automation** contributing to this repository.
+They exist so that automated changes are always reviewed by a human before they land. Humans
+contributing in the normal way are unaffected.
+
+## Rules
+
+1. **Never commit or push directly to a protected branch.** Do **not** push to `main` or to any
+   `dev-*` branch. Changes to those branches happen **only** through a pull request that a human
+   reviews and merges.
+
+2. **Do your work on a feature branch**, named with the prefix **`ai-feature-`**
+   (e.g. `ai-feature-fix-ontology-parse`). One logical change per branch.
+
+3. **Propose changes via pull request.** Open a PR from your `ai-feature-…` branch into `main` and
+   leave it for human review. **Do not merge your own PR**, and never bypass branch protection.
+
+4. **Never force-push** a shared branch and never rewrite published history.
