# Phase 2: Pre-Deployment Validation Skill

When validating solution architecture artifacts:

1. **Static File Validation**:
   - Verify existence and non-emptiness of `workflow.yaml`, `requirements.yaml`, `docs/requirements.md`, `docs/architecture.md`, `architecture.mmd`, `terraform/main.tf`, `solution-architecture-guide.md`.
2. **Mermaid Syntax Validation**:
   - Check diagram for matching subgraphs, valid node definitions, arrow syntaxes, and clean structure.
3. **Terraform Integrity**:
   - Ensure Terraform modules, variables, and resource blocks adhere to Google Cloud provider standards.
   - Ensure static non-provisioning check passes (`deploy_resources: false`).
4. **Output Report**:
   - Generate `validation-results.md` summarizing pass/fail status across all verification rules.
