+
+   After creating or updating the PR, determine if the PR is non-trivial and add the `cc:request` label to trigger a code review.
+
+   A PR is **trivial** (skip the label) if it ONLY contains:
+   - Documentation-only changes (`.md` files, comments)
+   - Snapshot/baseline updates with no test logic changes
+   - Single-line typo or formatting fixes
+
+   All other PRs are **non-trivial** (add the label), including:
+   - Any changes to source code (`.ts`, `.tsx`, `.js`, etc.)
+   - Changes to test logic (not just snapshot baselines)
+   - Configuration changes (`.yml`, `.json`, etc.)
+   - Any PR touching 3+ files
+
+   If the PR is non-trivial:
+
+   ```
+   gh pr edit --add-label "cc:request"

    After pushing, remove the `needs-human:review-issue` label if it exists (this label indicates the issue needed human review before work started, which is now complete):
