SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Azure deployment tasks often fail or produce unintended changes when executed without prior validation. This skill provides a rigorous preflight validation to catch syntax issues, permission gaps, and risky resource changes before deployment.

Core Features & Use Cases

  • Project type auto-detection: identifies azd projects or standalone Bicep setups and locates relevant Bicep and parameter files.
  • Syntax & what-if validation: runs Bicep CLI syntax checks and uses azd or az deployment what-if workflows to preview changes.
  • Consolidated reporting: aggregates issues into a standardized preflight-report.md with a structured summary, what-if results, and actionable recommendations.
  • Use Case: before deploying infrastructure, run a preflight to preview resource changes and verify permissions to prevent failed deployments.

Quick Start

To start a preflight validation, ensure Azure CLI, Bicep CLI, and optionally azd are installed, then run the skill against your Azure Bicep project and review preflight-report.md generated in the project root.

FAQPage Schema
How do I validate Azure Bicep deployments before running them?

Preflight validation for Azure Bicep deployments runs Bicep CLI syntax checks and Azure CLI what-if analysis to preview resource changes. It auto-detects project setups, validates parameters, and aggregates issues into a markdown report to prevent failed deployments.

What does an Azure Bicep what-if deployment check include?

An Azure Bicep what-if deployment check includes syntax validation, resource change previewing, and permission gap detection. It executes what-if workflows using Azure Developer CLI or Azure CLI to identify risky changes and aggregates findings into a structured preflight report.

Do I need Azure Developer CLI to run preflight validation on Bicep files?

You do not strictly need Azure Developer CLI to run preflight validation, but it is recommended. The process requires Bicep CLI and Azure CLI for syntax checks and what-if analysis, while optionally using Azure Developer CLI to auto-detect azd projects.

How do I preview Azure resource changes before deploying infrastructure?

To preview Azure resource changes before deploying, run a preflight validation skill that executes what-if analysis on your Bicep files. This previews modifications to resources and verifies permissions, consolidating results into a preflight-report.md file for review.

Can I validate standalone Bicep files without an azd project?

Yes, you can validate standalone Bicep files without an azd project. Preflight validation features project type auto-detection, allowing it to identify and validate standalone Bicep setups by locating relevant Bicep and parameter files directly.

Why do my Azure deployments fail without prior syntax validation?

Azure deployments often fail without prior syntax validation due to undetected code issues, permission gaps, or risky resource changes. Running a Bicep preflight check executes syntax validation and what-if analysis to catch these errors before deployment occurs.
