+# Agent Instructions
+
+- Follow the repository's established engineering practices and keep changes scoped to the task.
+- After completing work, check CI status and ensure CI checks pass before handing off.
+- For local validation, prefer the same checks used by CI: `make lint`, `make test`, and `make test-integration`.
