+        Core workspace engine. Data shapes must stay consistent with DATA_CONTRACT.md — flag changes that drift from it.
+    - path: "src/cli/**"
+      instructions: |
+        CLI layer. Keep commands thin — flag business logic that belongs in src/core.
+    - path: ".agents/skills/**"
+      instructions: |
+        Agent skill definitions (markdown instructions, not code). Review for clarity and correct tool references, not code style.
