## What it does

This skill answers one question: will your cluster move to AKS Automatic without surprises? It compares workloads and cluster settings against the Deployment Safeguards rule set that AKS Automatic runs in Enforce mode, where some rules deny, some only warn and some mutate fields at admission. Pod Security Standards at Baseline and cluster-level configuration requirements are part of the check too.

There are two ways in. With a connected cluster context, the skill reads metadata through Azure MCP AKS and pulls workloads through `scripts/sanitize-readiness-input.jq`, which needs `jq` installed. Without a cluster, it scans the workspace for local manifests, Helm charts and Kustomize overlays and evaluates them offline. Everything is read-only — no `kubectl apply`, no cluster state changes.

Every fix arrives as a diff, and nothing gets written to your files until you accept it. Secret values and ConfigMap data stay out of the output. Worth knowing before you start: the skill assesses migration readiness, it does not create clusters. For a new AKS Automatic cluster you want the `azure-kubernetes` skill instead.

## Requirements
- Works with: Azure, Kubernetes

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill azure-kubernetes-automatic-readiness -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/azure-kubernetes-automatic-readiness/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/azure-kubernetes-automatic-readiness/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/azure-kubernetes-automatic-readiness/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/azure-kubernetes-automatic-readiness/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills azure-kubernetes-automatic-readiness
```

2. **Manually: put the files in place**
- File: `.github/skills/azure-kubernetes-automatic-readiness/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-skills/skills/azure-kubernetes/azure-kubernetes-automatic-readiness
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/azure-kubernetes-automatic-readiness/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/azure-skills/skills/azure-kubernetes/azure-kubernetes-automatic-readiness/SKILL.md

## When to use it
- check whether a cluster can move to AKS Automatic
- find migration blockers in Kubernetes manifests
- validate Deployments, StatefulSets and CronJobs against Safeguards rules
- get ready-to-apply diffs for Automatic compatibility
- assess local Helm charts without a live cluster

## Example prompts
- Check my cluster for AKS Automatic readiness
- Validate the manifests in `deploy/` against AKS Automatic constraints
- What is blocking my migration from AKS Standard to AKS Automatic?

# AKS Automatic Readiness Assessment

> **AUTHORITATIVE GUIDANCE — MANDATORY COMPLIANCE**
>
> This skill assesses existing AKS clusters or local manifests for AKS Automatic compatibility.
> For creating a new AKS Automatic cluster, use the `azure-kubernetes` skill instead.
> See [constraint spec](./references/constraint-spec-v1.yaml) for all safeguard rules, [common fixes](./references/common-fixes.md) for YAML patterns, [migration guide](./references/migration-guide-summary.md) for end-to-end steps, and [MCP integration](./references/mcp-integration.md) for tool details and fallback handling.

You are an AKS Automatic compatibility assessment agent. Your job is to evaluate whether Kubernetes workloads and cluster configurations are compatible with [AKS Automatic](https://learn.microsoft.com/en-us/azure/aks/intro-aks-automatic), identify issues, and help users fix them.

AKS Automatic enables **Deployment Safeguards** in Enforce mode by default (some rules deny, some warn only, some mutate), **Pod Security Standards** at Baseline (Restricted is opt-in), **2 active webhook mutators** that auto-fix certain fields at admission (resource-requests defaults and anti-affinity/topology-spread), and a set of cluster-level configuration requirements. The bundled constraint spec is the rule source; rule counts in prose are descriptive, not proof of what a given cluster enforces.

## Quick Reference
| Property | Value |
|----------|-------|
| Best for | AKS Automatic migration readiness and manifest validation |
| MCP Tools | Host-discovered Azure MCP AKS capability (`mcp_azure_mcp_aks` in GitHub Copilot) for cluster/node-pool reads; `kubectl` + `jq` for sanitized workload reads |
| Related skills | azure-kubernetes (cluster creation), azure-diagnostics (live troubleshooting), aks-troubleshooting (AKS-focused diagnosis when the aks-skills plugin is installed), azure-validate (readiness checks) |

## When to Use This Skill
- "Can I migrate to AKS Automatic?"
- "Check my cluster readiness for Automatic"
- "Validate manifests against AKS Automatic constraints"
- "Fix my deployment for Automatic compatibility"
```
