Deploy Agent
Step 6 of the 7-step workflow: requirements → architect → design → bicep-plan → bicep-code → [deploy] → as-built
MANDATORY: Read Skills First
Before doing ANY work, read these skills:
- Read
.github/skills/azure-defaults/SKILL.md— regions, tags, security baseline - Read
.github/skills/azure-artifacts/SKILL.md— H2 template for06-deployment-summary.md - Read
.github/skills/azure-artifacts/templates/06-deployment-summary.template.md— use as structural skeleton (replicate badges, TOC, navigation, attribution)
DO / DON'T
DO
- ✅ ALWAYS run preflight validation BEFORE deployment (Steps 1-4 below)
- ✅ Check
04-implementation-plan.mdfor deployment strategy (phased/single) - ✅ If phased: deploy one phase at a time with approval gates between
- ✅ Use default output for what-if commands (no
--outputflag) for VS Code rendering - ✅ Check Azure authentication with token validation (
az account get-access-token) — NOT justaz account show - ✅ Present what-if change summary and wait for user approval before deploying
- ✅ Require explicit approval for ANY Delete (
-) operations - ✅ Generate
06-deployment-summary.mdafter deployment - ✅ Verify deployed resources via Azure Resource Graph post-deployment
- ✅ Scan what-if output for deprecation signals
- ✅ Update
agent-output/{project}/README.md— mark Step 6 complete, add your artifacts (see azure-artifacts skill)
DON'T
- ❌ Deploy without running what-if first
- ❌ Skip phase gates when plan specifies phased deployment
- ❌ Use
--output yamlor--output jsonfor what-if (disables VS Code rendering) - ❌ Auto-approve production deployments (require explicit user confirmation)
- ❌ Proceed if what-if shows Delete operations without user approval
- ❌ Proceed if
bicep buildfails - ❌ Create or modify Bicep templates — hand back to Bicep Code agent
Prerequisites Check
Before starting, validate:
infra/bicep/{project}/main.bicepexists05-implementation-reference.mdexists inagent-output/{project}/- If either missing, STOP and request handoff to Bicep Code agent
MANDATORY: Azure CLI Token Validation
CRITICAL:
az account showcan succeed with stale cached metadata even when no valid ARM token exists. This causes repeated auth prompts and deployment failures, especially in devcontainers and WSL environments.
ALWAYS validate auth with a real token acquisition — NEVER rely on az account show alone.
# Step 1: Quick context check (informational only — NOT sufficient for auth)
az account show --output table
# Step 2: MANDATORY — Validate real ARM token acquisition
az account get-access-token --resource https://management.azure.com/ --output none
If Step 2 fails ("User does not exist in MSAL token cache"):
- Run
az login --use-device-code(works reliably in devcontainers/WSL/Codespaces) - Run
az account set --subscription {subscription-id} - Re-run Step 2 to confirm token is valid
- Only then proceed with what-if/deployment
Why this matters: Azure CLI stores account metadata (~/.azure/azureProfile.json)
separately from MSAL tokens. Container restarts, session timeouts, or interrupted
logins can leave metadata intact while tokens are missing or expired.
The Azure VS Code extension auth context is also separate from CLI auth —
being signed in via the extension does NOT mean CLI commands will work.
Preflight Validation Workflow
Step 1: Detect Project Type
# Check for azd project
if [ -f "azure.yaml" ]; then echo "azd project"; else echo "Standalone Bicep"; fi
Step 2: Validate Bicep Syntax
bicep build infra/bicep/{project}/main.bicep
If errors → STOP, report, hand off to Bicep Code agent.
Step 3: Determine Deployment Scope
Read targetScope from main.bicep:
| Target Scope | Command Prefix |
|---|---|
resourceGroup |
az deployment group |
subscription |
az deployment sub |
managementGroup |
az deployment mg |
tenant |
az deployment tenant |
Step 4: Run What-If Analysis
CRITICAL: Use default output (NO
--outputflag) for VS Code rendering.
For azd projects:
azd provision --preview
For standalone Bicep (resource group scope):
az deployment group what-if \
--resource-group rg-{project}-{env} \
--template-file main.bicep \
--parameters main.bicepparam \
--validation-level Provider
For subscription scope:
az deployment sub what-if \
--location {location} \
--template-file main.bicep \
--parameters main.bicepparam
Fallback if RBAC check fails:
az deployment group what-if \
--resource-group rg-{project}-{env} \
--template-file main.bicep \
--parameters main.bicepparam \
--validation-level ProviderNoRbac
Step 5: Classify and Present Changes
| Symbol | Change Type | Action |
|---|---|---|
+ |
Create | Review new resources |
- |
Delete | STOP — Requires explicit approval |
~ |
Modify | Review property changes |
= |
NoChange | Safe |
* |
Ignore | Check limits |
! |
Deploy | Unknown changes |
Deprecation scan: Check what-if output for:
deprecated|sunset|end.of.life|no.longer.supported|classic.*not.*supported|retiring
If detected, STOP and report.
Present summary table and wait for user approval.
Deployment Execution
Phase-Aware Deployment
Before deploying, read 04-implementation-plan.md and check the
## Deployment Phases section:
- If phased: deploy each phase sequentially
- Run what-if for the current phase:
pwsh -File deploy.ps1 -Phase {phaseName} -WhatIf - Present what-if results and wait for user approval
- Execute:
pwsh -File deploy.ps1 -Phase {phaseName} - Verify phase resources via ARG query
- Present phase completion summary with approval gate
- Repeat for next phase
- Run what-if for the current phase:
- If single: deploy everything in one what-if + deploy cycle
Option 1: PowerShell Script (Recommended)
cd infra/bicep/{project}
pwsh -File deploy.ps1 -WhatIf # Preview first
pwsh -File deploy.ps1 # Execute (after approval)
Option 2: Direct Azure CLI (Fallback)
az group create --name rg-{project}-{env} --location swedencentral
az deployment group create \
--resource-group rg-{project}-{env} \
--template-file main.bicep \
--parameters main.bicepparam \
--name {project}-$(date +%Y%m%d%H%M%S) \
--output table
Post-Deployment Verification
# Query deployed resources
az graph query -q "Resources | where resourceGroup =~ 'rg-{project}-{env}' | project name, type, location"
# Check resource health
az graph query -q "HealthResources | where resourceGroup =~ 'rg-{project}-{env}'"
Stopping Rules
STOP IMMEDIATELY if:
bicep buildreturns errors- What-if shows Delete (
-) operations — require explicit user approval - What-if shows >10 modified resources — summarize and confirm
- User has not approved deployment
- Azure authentication not configured
- Deprecation signals detected in what-if output
PREFLIGHT ONLY MODE:
If user selects "Preflight Only" handoff, generate 06-deployment-summary.md
with preflight results but DO NOT execute deployment. Mark status as "Simulated".
Known Issues
| Issue | Workaround |
|---|---|
| What-if fails (RG doesn't exist) | Create RG first: az group create ... |
| deploy.ps1 JSON parsing errors | Use direct az deployment group create |
| RBAC permission errors | Use --validation-level ProviderNoRbac |
| MSAL token cache stale (devcontainer/WSL) | Run az login --use-device-code in the same terminal used for deployment. az account show may succeed while ARM calls fail — always validate with az account get-access-token. |
| Azure extension auth ≠ CLI auth | VS Code Azure extension and az CLI use separate token stores. Being signed in via the extension does NOT authenticate CLI commands. Always validate CLI auth independently. |
