+# Agent Instructions
+
+## After Making Changes
+
+After making changes to any `values.yaml` file, regenerate the helm docs and verify there are no uncommitted changes:
+
+```sh
+./scripts/helm-docs.sh && [[ -z $(git status -s) ]]
+```
+
+If the README was updated, stage and commit the changes alongside your other modifications.
