## Description

Assess whether source code is ready to deploy to Azure, the check BEFORE infrastructure work. Evaluates build health, app completeness, dependencies and local services, stack compatibility, and deployment feasibility. Answers questions about what your app needs before it can be deployed, frameworks, dependencies, and configuration. Checks whether dependencies are compatible and identifies deployment blockers and unsupported frameworks. WHEN: \"evaluate my repo\", \"is my app ready to deploy\", \"what does my app need to deploy\", \"what do I need before deploying\", \"does my app need\", \"can I ship this to Azure\", \"scan my repo for issues\", \"is this app deployable\", \"check if my app is ready for Azure\", \"do I need a Dockerfile\", \"what's blocking my deployment\", \"are there any blockers\", \"are my dependencies compatible\", \"does Azure support my framework\", \"what needs to change before deploying\", \"check my app configuration\".

# Azure App Onboard Prereq, Repository Evaluation

Evaluate a user's repository for build health, app completeness, and Azure deployment feasibility, before infrastructure planning. Produces per-component verdicts (PASS/WARN/FAIL) consumed by downstream phases.

> **Orchestrator relationship:** Called by `azure-app-onboard` at Step 3, or standalone for code readiness checks. When called by orchestrator, return control to `azure-app-onboard` after writing artifacts, do NOT invoke downstream phases directly.

Phase 1 of 4 in AppOnboard pipeline. Session: `.copilot-azure/sessions/{session-id}/`. Reads `context.json`. Writes `components[]`, `repo{}`, `detectedInfra[]`. Produces `prereq-output.json`. Schema: [`prereq-schemas.ts`](references/prereq-schemas.ts), `PrereqOutput`, `BuildRequirements`. Direct entry supported.

## When NOT to Use

| Validate infrastructure (Bicep/TF/azure.yaml) | **azure-validate** |
| Generate IaC | **azure-prepare** |
| End-to-end idea-to-production | **azure-app-onboard** |
| Run `azd up` or deploy | **azure-deploy** |
