 ### Automatic Python stub updates
 
-With `check-stubs: true`, the Python linter now fixes outdated `.pyi` files
-under `python/` on same-repository PR branches other than the default branch.
-The fix runs as a follow-up step in the linter job.
+With `check-stubs: true`, the Python linter can now commit regenerated stubs
+automatically. To enable this, forward the organization or repository secrets in
+the job calling `reusable-python-linter.yml`:
+
+```yaml
+secrets:
+  APP_ID: ${{ secrets.APP_ID }}
+  APP_PRIVATE_KEY: ${{ secrets.APP_PRIVATE_KEY }}
+```
 
-Define `APP_ID` and `APP_PRIVATE_KEY` in the calling repository's `mqt-app`
-environment, or pass them explicitly from the caller. Organization secrets
-require forwarding. The App needs Contents write and Pull requests read access.
-Without credentials, or for fork PRs, the check keeps the manual `nox -s stubs`
-instructions.
+Without these secrets, outdated stubs must still be regenerated and committed
+manually.
