 ### 7. Commit Changes
 - **ALWAYS commit** after successful implementation
-- Ensure the code builds (`go build`)
-- Ensure all tests pass (`go test`)
-- Ensure there are no linter issues (`make lint`)
-- Ensure there are no fmt issues (`make fmt-check`)
+- Verify that everything is in order before commit:
+  - there is a Gitea Runner image in ci/pre-commit
+    - run scripts/pre-commit-check.sh
+      - Ensure the code builds (`make build`)
+      - Ensure all tests pass (`make test`)
+      - Ensure there are no linter issues (`make lint`)
+      - Ensure there are no fmt issues (`make fmt-check`)
+    - If there are issues, fix them before comitting
 - Verify all acceptance criteria are met
 - Write a clear, descriptive commit message
