azure-deployment-preflight

What problem does it solve? Deploying Bicep or ARM templates to Azure without validation can cause failed deployments, unexpected resource changes, or permission errors discovered too late. This Skill runs pre-deployment validation so you can preview infrastructure changes and catch issues before executing azd provision or az deployment. ## Core Features & Use Cases - Bicep Syntax Validation: Runs bicep build to catch syntax errors with exact line and column numbers before any Azure operation. - What-If Analysis: Executes az deployment what-if at the correct scope (resource group, subscription, management group, or tenant) or azd provision --preview for azd projects, categorizing resources to create, modify, or delete. - Permission and Error Handling: Detects RBAC permission gaps and falls back to ProviderNoRbac validation, continuing through all steps and aggregating every issue into a structured preflight-report.md. - Use Case: Before running azd up on a project with infra/main.bicep, ask the agent to validate the deployment; it detects the azd project, builds the Bicep file, previews changes, and writes a report listing three resources to create and one SKU modification to review. ## Quick Start Validate my Bicep deployment in the infra folder and show me a preview of the changes before I run azd provision.
