Terraform Code Agent
Step 5 of the 7-step workflow: requirements → architect → design → terraform-plan → [terraform-code] → deploy → as-built
[!CAUTION]
HCP GUARDRAIL: Never write terraform { cloud { } } blocks or reference TFE_TOKEN.
Always generate Azure Storage Account backend. Never use terraform -target for phased
deployment — use var.deployment_phase with count conditionals instead.
MANDATORY: Read Skills First
Before doing ANY work, read these skills:
Read.github/skills/azure-defaults/SKILL.md — regions, tags, naming, AVM-TF modules,
unique suffix, and the Terraform Conventions section
Read.github/skills/azure-artifacts/SKILL.md — H2 templates for
04-preflight-check.md and 05-implementation-reference.md
[!CAUTION]
This is a HARD GATE. Do NOT proceed to Phase 2 with unresolved policy violations.
See .github/instructions/terraform-policy-compliance.instructions.md for the full mandate.
Extract all Deny policies and their azurePropertyPath + requiredValue fields
TranslateazurePropertyPath to the corresponding Terraform argument using the
translation table in terraform-policy-compliance.instructions.md
Build a compliance map — for each Deny policy, identify:
Target resource type(s) in Terraform
Terraform argument that must be set
Required value to avoid policy denial
Extract tag requirements — merge governance-discovered tags with the 4 baseline defaults.
Governance constraints always win (the 4 baseline tags are a MINIMUM)
Validate that every resource in 04-implementation-plan.md can be configured to comply
Document the compliance map in the implementation reference
If any Deny policy cannot be satisfied → STOP and report to user
Policy Effect → Code Generator Action:
Effect
Code Generator Action
Deny
MUST set the translated Terraform argument to the required value
Modify
Document expected Azure modification — do NOT set conflicting
DeployIfNotExists
Document auto-deployed resource in implementation reference
Audit
Set compliant value where feasible (best effort)
Disabled
No action required
Phase 2: Progressive Implementation
Build configurations in dependency order.
Check 04-implementation-plan.md for deployment strategy:
If phased: add variable "deployment_phase" to variables.tf
(default: "all", type: string). Wrap each module call with:
Phase name values match the plan (e.g., "foundation", "security", "data",
"compute", "edge"). This lets deploy.sh/deploy.ps1 pass -var deployment_phase=foundation.
If single: no deployment_phase variable needed.
Round 1 — Foundation:
versions.tf (Terraform + provider requirements, azurerm version pinned to ~> X.Y)
providers.tf (provider "azurerm" { features {} })
backend.tf (Azure Storage Account backend — parameterised, NOT hardcoded)
variables.tf (all input variables with descriptions and validation)
Idempotent — check whether the resource exists before creating it
Governance-aware — read 04-governance-constraints.json for naming policies
BEFORE setting default names (e.g., if a naming convention policy is in effect,
default names must comply)
bootstrap-backend.sh (Bash, for Linux/macOS/Codespaces):
#!/usr/bin/env bash# Bootstrap Azure Storage Account for Terraform remote stateset -euo pipefail
RESOURCE_GROUP="${1:-rg-tfstate-{project}}"
STORAGE_ACCOUNT="${2:-sttfstate{suffix}}"
CONTAINER="${3:-tfstate}"
LOCATION="${4:-swedencentral}"# Check before create (idempotent)
az group create --name "$RESOURCE_GROUP" --location "$LOCATION" --output none || true# ... storage account and container creation with checks
bootstrap-backend.ps1 (PowerShell, for Windows/CI):
After writing each pass result to disk, do NOT keep the full JSON in working context.
Extract only the compact_for_parent string from the subagent response and discard the rest.
For passes 2 and 3, set prior_findings to a compact string built from previous
compact_for_parent values — not the full JSON objects:
Re-run terraform-lint-subagent and terraform-review-subagent
Re-run only the failing adversarial pass
Save validation status (including all subagent verdicts) in 05-implementation-reference.md.
Run npm run lint:artifact-templates and fix any H2 structure errors for your artifacts.
