azure-enterprise-infra-planner

name	azure-enterprise-infra-planner
description	Architect and provision enterprise Azure infrastructure from workload descriptions. For cloud architects and platform engineers planning networking, identity, security, compliance, and multi-resource topologies with WAF alignment. Generates Bicep or Terraform directly (no azd). WHEN: 'plan Azure infrastructure', 'architect Azure landing zone', 'design hub-spoke network', 'plan multi-region DR topology', 'set up VNets firewalls and private endpoints', 'subscription-scope Bicep deployment', 'Azure Backup for VM workloads'. PREFER azure-prepare FOR app-centric workflows.

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.

MCP Tools

Tool	Purpose
insights_get	Retrieve insights about the user's existing Azure environment to guide planning decisions
get_azure_bestpractices_get	Azure best practices for code generation, operations, and deployment
wellarchitectedframework_serviceguide_get	WAF service guide for a specific Azure service
microsoft_docs_search	Search Microsoft Learn for relevant documentation chunks
microsoft_docs_fetch	Fetch full content of a Microsoft Learn page by URL
bicepschema_get	Bicep schema definition for any Azure resource type (latest API version)

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
