azure-deployment-preflight

Bicep template validation checks syntax correctness and resource definitions using Bicep CLI. This Skill runs syntax checks automatically, then performs what-if analysis to preview resource changes and identify deployment issues before execution, catching errors early.

Yes. This Skill verifies RBAC permissions required for your deployment, reports gaps in your current access level, and generates a readiness report so you know exactly what permissions are needed before attempting deployment.

Azure CLI what-if analysis simulates deployment changes without modifying live resources. This Skill runs what-if validation on your Bicep templates to show exact resource additions, modifications, and deletions you can review and approve before committing.

Both workflows are supported. This Skill detects whether you're using an azd project or standalone Bicep deployment, then executes the appropriate validation path. Azure CLI and Bicep CLI are required; Azure Developer CLI is optional.

The preflight report details all syntax errors, permission gaps, and resource conflicts in a single output. You review the report, fix issues locally, then re-run validation until the template passes all checks and is deployment-ready.

Yes. This Skill integrates with azd workflows by detecting your project structure and running preflight validation against your Bicep templates and deployment context, generating a readiness report before you execute azd deploy.
