Azure Enterprise Infra Planner
When to Use This Skill
Activate this skill when user wants to:
- Plan enterprise Azure infrastructure from a workload or architecture description
- Architect a landing zone, hub-spoke network, or multi-region topology
- Design networking infrastructure: VNets, subnets, firewalls, private endpoints, VPN gateways
- Plan identity, RBAC, and compliance-driven infrastructure
- Generate Bicep or Terraform for subscription-scope or multi-resource-group deployments
- Plan disaster recovery, failover, or cross-region high-availability topologies

Workflow (Start Here)
Follow the step-by-step instructions in workflow.md to execute the 7 phases of infrastructure planning and provisioning.
Architecture
The skill runs a 7-phase, gated pipeline. Input is triaged into one of two flows:
- Greenfield — only new requirements; run the phases straight through.
- Referenced (brownfield) — the user supplies something that already exists (a live resource /
resource group / subscription, IaC or an infra plan, or a requirements doc). The same phases run, plus referenced-workload.md: existing resources are inventoried and referenced (never recreated), the new workload is wired into them, and Phase 7 deploys additively (incremental only — never modifying or destroying the referenced resources).
Every phase advances only after its gate passes. Phase 5 requires explicit user approval; Phase 6 is a hardened, self-verifying gate — the generated IaC must be secure-by-default, pass local validation (az bicep build / terraform validate) with zero errors, pass a checkov security scan with no unresolved high/critical findings, and the skill must show the command output and emit a completion self-check before advancing; Phase 7 requires an explicit, risk-acknowledged deploy confirmation.

Error Handling
| Error | Cause | Fix |
|---|---|---|
| MCP tool error or not available | Tool call timeout, connection error, or tool doesn't exist | Retry once; fall back to reference files and notify user if unresolved |
| Plan approval missing | meta.status is not approved | Stop and prompt user for approval before IaC generation or deployment |
| IaC validation failure | az bicep build or terraform validate returns errors | Fix the generated code and re-validate; notify user if unresolved |
| Pairing constraint violation | Incompatible SKU or resource combination | Fix in plan before proceeding to IaC generation |
| Infra plan or IaC files not found | Files written to wrong location or not created | Verify files exist at <project-root>/.azure/ and <project-root>/infra/; if missing, re-create the files by following workflow.md exactly |
