14## Agent Behavior Validation
15 
16```text
171. Agent calls: functions_template_get(language: "typescript")
182. Agent scans templateList.triggers[] descriptions and resource field
193. Agent selects: template where resource == "cosmos" → cosmos-trigger-typescript-azd
204. Agent calls: functions_template_get(language: "typescript", template: "cosmos-trigger-typescript-azd")
215. Agent writes: functionFiles[] + projectFiles[]

26- `app.cosmosDB` trigger binding (V4 model)
27- TypeScript compilation successful (`npm install` + `tsc`)
28- Cosmos DB with managed identity and proper RBAC assignments
29- Infrastructure uses `Microsoft.DocumentDB`
