Azure Deployment Preflight

The azure-deployment-preflight skill validates Bicep infrastructure templates before deployment to Azure by checking syntax, running what-if analysis, and verifying user permissions across both Azure CLI and Azure Developer CLI workflows. It's designed for developers and DevOps engineers preparing infrastructure code for Azure to catch deployment errors, preview infrastructure changes, and confirm sufficient permissions before execution. The skill solves the problem of failed or unexpected deployments by providing comprehensive preflight validation that identifies issues early in the deployment process.

Azure Deployment Preflight Validation

This skill validates Bicep deployments before execution, supporting both Azure CLI (az) and Azure Developer CLI (azd) workflows.

When to Use This Skill

Before deploying infrastructure to Azure
When preparing or reviewing Bicep files
To preview what changes a deployment will make
To verify permissions are sufficient for deployment
Before running azd up, azd provision, or az deployment commands

Validation Process

Follow these steps in order. Continue to the next step even if a previous step fails—capture all issues in the final report.

Step 1: Detect Project Type

Determine the deployment workflow by checking for project indicators:

Check for azd project: Look for azure.yaml in the project root
- If found → Use azd workflow
- If not found → Use az CLI workflow
Locate Bicep files: Find all .bicep files to validate
- For azd projects: Check infra/ directory first, then project root
- For standalone: Use the file specified by the user or search common locations (infra/, deploy/, project root)
