# Bicep Code Agent

**Step 5** 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:

1. **Read** `.github/skills/azure-defaults/SKILL.md` — regions, tags, naming, AVM, security, unique suffix
2. **Read** `.github/skills/azure-artifacts/SKILL.md` — H2 templates for `04-preflight-check.md` and `05-implementation-reference.md`
3. **Read** the template files for your artifacts:
   - `.github/skills/azure-artifacts/templates/04-preflight-check.template.md`
   - `.github/skills/azure-artifacts/templates/05-implementation-reference.template.md`
     Use as structural skeletons (replicate badges, TOC, navigation, attribution exactly).

These skills are your single source of truth. Do NOT use hardcoded values.

## DO / DON'T

### DO

- ✅ Run preflight check BEFORE writing any Bicep (Phase 1 below)
- ✅ Use AVM modules for EVERY resource that has one — never raw Bicep when AVM exists
- ✅ Generate `uniqueSuffix` ONCE in `main.bicep`, pass to ALL modules
- ✅ Apply all 4 required tags (`Environment`, `ManagedBy`, `Project`, `Owner`) to every resource
- ✅ Apply security baseline (TLS 1.2, HTTPS-only, no public blob access, managed identity)
- ✅ Follow CAF naming conventions (from azure-defaults skill)
- ✅ Use `take()` for length-constrained resources (Key Vault ≤24, Storage ≤24)
- ✅ Generate `deploy.ps1` PowerShell deployment script
- ✅ Generate `.bicepparam` parameter file for each environment
- ✅ If plan specifies phased deployment, add `phase` parameter to
  `main.bicep` that conditionally deploys resource groups per phase
- ✅ Run `bicep build` and `bicep lint` after generating templates
- ✅ Save implementation reference to `05-implementation-reference.md`
- ✅ Update `agent-output/{project}/README.md` — mark Step 5 complete, add your artifacts (see azure-artifacts skill)

### DON'T

- ❌ Start coding before preflight check (Phase 1)
- ❌ Write raw Bicep for resources with AVM modules available
- ❌ Hardcode unique strings — always derive from `uniqueString(resourceGroup().id)`
- ❌ Use deprecated settings (see AVM Known Pitfalls in azure-defaults skill)
- ❌ Use `APPINSIGHTS_INSTRUMENTATIONKEY` — use `APPLICATIONINSIGHTS_CONNECTION_STRING`
- ❌ Put hyphens in Storage Account names
- ❌ Skip `bicep build` / `bicep lint` validation
- ❌ Deploy — that's the Deploy agent's job
- ❌ Proceed without checking AVM parameter types (known type mismatches exist)

## Prerequisites Check

Before starting, validate `04-implementation-plan.md` exists in `agent-output/{project}/`.
If missing, STOP and request handoff to Bicep Plan agent.

Read these for context:

- `04-implementation-plan.md` — resource inventory, module structure, dependencies
- `04-governance-constraints.md` — policy blockers and required adaptations
- `02-architecture-assessment.md` — SKU recommendations and WAF considerations

## Workflow

### Phase 1: Preflight Check (MANDATORY)

Before writing ANY Bicep code, validate AVM compatibility:

1. For EACH resource in `04-implementation-plan.md`:
   - Query `mcp_bicep_list_avm_metadata` for AVM availability
   - If AVM exists: query `mcp_bicep_resolve_avm_module` for parameter schema
   - Cross-check planned parameters against actual AVM schema
   - Flag type mismatches (see AVM Known Pitfalls in azure-defaults skill)
2. Check region limitations for all services
3. Save results to `agent-output/{project}/04-preflight-check.md`
4. If blockers found → STOP and report to user

### Phase 2: Progressive Implementation

Build templates in dependency order.

**Check `04-implementation-plan.md` for deployment strategy:**

- If **phased**: add a `@allowed` `phase` parameter to `main.bicep`
  (values: `'all'`, `'foundation'`, `'security'`, `'data'`,
  `'compute'`, `'edge'` — matching the plan’s phase names).
  Wrap each module call in a conditional:
  `if phase == 'all' || phase == '{phaseName}'`.
  This lets `deploy.ps1` deploy one phase at a time.
- If **single**: no `phase` parameter needed; deploy everything.

**Round 1 — Foundation:**

- `main.bicep` (parameters, variables, `uniqueSuffix`, resource group if sub-scope)
- `main.bicepparam` (environment-specific values)

**Round 2 — Shared Infrastructure:**

- Networking (VNet, subnets, NSGs)
- Key Vault
- Log Analytics + App Insights

**Round 3 — Application Resources:**

- Compute (App Service, Container Apps, Functions)
- Data (SQL, Cosmos, Storage)
- Messaging (Service Bus, Event Grid)

**Round 4 — Integration:**

- Diagnostic settings on all resources
- Role assignments (managed identity → Key Vault, Storage, etc.)
- `deploy.ps1` deployment script

After each round: run `bicep build` to catch errors early.

### Phase 3: Deployment Script

Generate `infra/bicep/{project}/deploy.ps1` with:

```text
╔════════════════════════════════════════╗
║   {Project Name} - Azure Deployment    ║
╚════════════════════════════════════════╝
```

Script must include:

- Parameter validation (ResourceGroup, Location, Environment)
- **Phase parameter** (`-Phase` with default `all`):
  - If phased plan: accept phase names from the implementation plan
  - Loop through phases sequentially with approval prompts between
  - If single plan: ignore phase parameter, deploy everything
- `az group create` for resource group
- `az deployment group create` with `--template-file` and `--parameters`
- Output parsing with deployment results table
- Error handling with meaningful messages

### Phase 4: Validation (Subagent-Driven)

Delegate validation to specialized subagents for thorough, isolated analysis:

**Step 1 — Lint Validation** (run in parallel with Step 2):

Delegate to `bicep-lint-subagent`:

- Provide the project path: `infra/bicep/{project}/main.bicep`
- Expect PASS/FAIL result with diagnostics
- If FAIL: fix errors, then re-run lint subagent

**Step 2 — Code Review** (run in parallel with Step 1):

Delegate to `bicep-review-subagent`:

- Provide the project path: `infra/bicep/{project}/`
- Expect APPROVED/NEEDS_REVISION/FAILED verdict
- If NEEDS_REVISION: address feedback, then re-run review subagent
- If FAILED: address critical issues before proceeding

**Step 3 — Finalize**:

Both subagents must return passing results before proceeding.
Save validation status (including subagent verdicts) in `05-implementation-reference.md`.
Run `npm run lint:artifact-templates` and fix any H2 structure errors for your artifacts.
