GitHub Copilot SDK on Azure

Step 1: Route

User wants	Action
Build new (empty project)	Step 2A (scaffold)
Add new SDK service to existing repo	Step 2B (scaffold alongside)
Deploy existing SDK app to Azure	Step 2C (add infra to existing SDK app)
Add SDK to existing app code	Integrate SDK
Use Azure/own model	Step 3 (BYOM config)

Step 2A: Scaffold New (Greenfield)

azd init --template azure-samples/copilot-sdk-service

Template includes API (Express/TS) + Web UI (React/Vite) + infra (Bicep) + Dockerfiles + token scripts — do NOT recreate. See SDK ref.

Step 2B: Add SDK Service to Existing Repo

User has existing code and wants a new Copilot SDK service alongside it. Scaffold template to a temp dir, copy the API service + infra into the user's repo, adapt azure.yaml to include both existing and new services. See deploy existing ref.

Step 2C: Deploy Existing SDK App

User already has a working Copilot SDK app and needs Azure infra. See deploy existing ref.

Step 3: Model Configuration

Three model paths (layers on top of 2A/2B):

Path	Config
GitHub default	No `model` param — SDK picks default
GitHub specific	`model: "<name>"` — use `listModels()` to discover
Azure BYOM	`model` + `provider` with `bearerToken` via `DefaultAzureCredential`

See model config ref.

Step 4: Deploy

Invoke azure-prepare (skip its Step 0 routing — scaffolding is done) → azure-validate → azure-deploy in order.
