# Kustomize Resource Validation -- Auto-trigger Skill Automatically activates when any `kustomization.yaml` file is edited. ## Activation **Trigger:** Any file named `kustomization.yaml` inside a Kustomize module directory (any directory containing `base/` and `overlays/` structure) is created or edited. **Scope:** This applies to both base and overlay `kustomization.yaml` files. ## Instructions After the user edits a `kustomization.yaml`, perform these validations in order. Use the file system tools (Glob, Read) to verify references -- do not guess. ### 1. Resource Reference Validation For every entry in the `resources:` list, verify the target exists: - **Directory references** (e.g., `../../base`): Resolve the relative path from the `kustomization.yaml` location and confirm the directory exists and contains its own `kustomization.yaml`. - **File references** (e.g., `gitlab-runner-secret.yaml`): Confirm the file exists in the same directory as the `kustomization.yaml`. Report missing references as **FAIL**. ### 2. Patch Reference Validation For every entry in the `patches:` list that uses a `path:` key, verify: - The referenced YAML file exists relative to the `kustomization.yaml` directory. - The file contains valid Kubernetes resource structure (must have `apiVersion`, `kind`, and `metadata` fields). Report missing or malformed patches as **FAIL**. ### 3. Orphaned File Detection List all `.yaml` files in the same directory as the `kustomization.yaml`, then
