+review:
+  instructions:
+    # Linter overlap — these are already enforced by golangci-lint in CI
+    - "Do not comment on issues caught by: errcheck, govet, ineffassign, staticcheck, unused, nosprintfhostport, gofmt"
+    - "Do not comment on import ordering or formatting"
+    - "Do not flag SA1019 deprecation warnings on client.Apply — this is intentionally suppressed"
+
+    # Style — established project conventions, not up for debate
+    - "Do not comment on error wrapping style (this project uses fmt.Errorf with %w consistently)"
+    - "Do not suggest renaming variables, functions, or packages"
+    - "Do not suggest extracting single-use helper functions"
+    - "Do not suggest adding comments to exported symbols unless the function is non-obvious"
+
+    # Architecture context
+    - "This project uses Kubernetes controller-runtime with Server-Side Apply (SSA)"
+    - "Controllers use distinct field managers and ForceOwnership — do not flag this as a concern"
+    - "Reconcile functions returning (*ctrl.Result, error) where nil result means continue is an intentional pattern"
+    - "Errors intentionally not returned to controller-runtime (returned as nil) is a deliberate choice to avoid requeue backoff — do not flag this"
+    - "log.FromContext(ctx) with V-levels is the logging convention — do not suggest alternatives"
+
+    # What to actually review
+    - "Focus on: logic errors, race conditions, resource leaks, deadlocks, nil pointer dereferences"
+    - "Flag: missing context cancellation checks, unbounded goroutines, missing error handling in deferred Close calls"
+    - "Flag: incorrect SSA field manager usage, writing fields owned by another controller"
+    - "Flag: security issues (credential leaks, injection, TOCTOU)"
+    - "Flag: incorrect Kubernetes API usage (wrong GVK, missing RBAC, broken owner references)"
