azure-enterprise-infra-planner

Turns a written description of what a company needs to run into a full network and security design for Azure, then into infrastructure code ready to deploy; nothing is created until you approve the plan.

WHEN TO USE

SCOPE

USE FOR

Design a hub-spoke network — virtual networks, firewalls, and private endpoints — for your Azure setup.
Plan a subscription-wide Azure landing zone starting from a plain description of the workload.
Architect a disaster-recovery setup spanning multiple regions, following Microsoft's Well-Architected Framework.
Add new infrastructure alongside an existing subscription without touching what's already there.
Get your generated infrastructure code checked by an automated security scan (Checkov) before it deploys.

NOT FOR

Planning infrastructure for a single, app-centric workload; use azure-prepare instead.

Azure Enterprise Infra Planner

When to Use This Skill

Activate this skill when user wants to:

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

This skill ships inside the Azure Skills Plugin. Listed package contents include hooks and an MCP server. Installed components and skill versions may vary by AI tool.

Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.

Install checklist

Check selected tools if a picker appears; Claude Code may be unchecked under Additional agents. ↑/↓ moves, Space toggles selections, Enter confirms.
Without a tool picker, check Installing to: for your intended tool. Stop if it names a different tool.
If asked, choose Symlink (Recommended) for shared files or Copy to all agents for separate copies; review the summary before confirming installation.
Install the find-skills skill? defaults to Yes, adding another skill for all projects. Choose No if you don't want that extra installation.

Skills CLI 1.7.2 sends install data to skills.sh by default, including the source, skill names, target tools and file details; GitHub sources are reported only when GitHub confirms the repository is public, while other remote sources can also be reported. Confirmed-public GitHub sources also trigger a security-audit request. Before installing, set the environment variable DO_NOT_TRACK=1 or DISABLE_TELEMETRY=1 to disable both.

npx skills add microsoft/azure-skills --skill "azure-enterprise-infra-planner" --full-depth

After installing for Claude Code, open it in the installation project if you chose Project; Global makes the skill available across projects on this computer. Once Claude Code loads the skill, its description helps Claude decide when to use it.

If installation created a top-level skills folder that did not exist when your Claude Code session started, run /reload-skills in that session. Run it again after later changes in that folder.
