## What it does

This skill evaluates available capacity and tokens-per-minute (TPM) quotas for Azure OpenAI models across all accessible regions. It operates strictly in read-only mode, building a ranked table of deployment targets sorted by capacity targets and existing projects without creating resources.

The workflow runs bundled PowerShell and Bash scripts. While `query_capacity` checks supported model versions, `discover_and_rank` evaluates platform availability against active AI Services projects. It also runs `az cognitiveservices usage list` to verify whether the subscription actually holds free quota for each SKU.

Without an active `az login` session, all discovery scripts immediately fail on execution. If every region hits quota limits, the skill points you to the Azure Portal or delegates the increase request to the companion `quota` skill.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

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

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

### Codex

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

### Cursor

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills capacity
```

2. **Manually: put the files in place**
- File: `.github/skills/capacity/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-skills/skills/microsoft-foundry/models/deploy-model/capacity
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/capacity/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/microsoft-foundry/models/deploy-model/capacity/SKILL.md

## When to use it
- find regions with target TPM capacity for an Azure OpenAI model
- validate remaining subscription quota across regions before deploying
- identify fallback deployment locations after quota errors
- rank candidate regions by capacity and existing project count

## Example prompts
- Where can I deploy gpt-4o with 10K TPM?
- Check available quota for gpt-4o across all accessible regions
- Find the best region and project for deploying gpt-4o

# Capacity Discovery

Finds available Azure OpenAI model capacity across all accessible regions and projects. Recommends the best deployment location based on capacity requirements.

## Quick Reference

| Property | Description |
|----------|-------------|
| **Purpose** | Find where you can deploy a model with sufficient capacity |
| **Scope** | All regions and projects the user has access to |
| **Output** | Ranked table of regions/projects with available capacity |
| **Action** | Read-only analysis — does NOT deploy. Hands off to preset or customize |
| **Authentication** | Azure CLI (`az login`) |

## When to Use This Skill

- ✅ User asks "where can I deploy gpt-4o?"
- ✅ User specifies a capacity target: "find a region with 10K TPM for gpt-4o"
- ✅ User wants to compare availability: "which regions have gpt-4o available?"
- ✅ User got a quota error and needs to find an alternative location
- ✅ User asks "best region and project for deploying model X"

**After discovery → hand off to [preset](../preset/SKILL.md) or [customize](../customize/SKILL.md) for actual deployment.**

## Scripts

Pre-built scripts handle the complex REST API calls and data processing. Use these instead of constructing commands manually.

| Script | Purpose | Usage |
|--------|---------|-------|
| `scripts/discover_and_rank.ps1` | Full discovery: capacity + projects + ranking | Primary script for capacity discovery |
| `scripts/discover_and_rank.sh` | Same as above (bash) | Primary script for capacity discovery |
| `scripts/query_capacity.ps1` | Raw capacity query (no project matching) | Quick capacity check or version listing |
| `scripts/query_capacity.sh` | Same as above (bash) | Quick capacity check or version listing |

## Workflow

### Phase 1: Validate Prerequisites

```bash
az account show --query "{Subscription:name, SubscriptionId:id}" --output table
```

### Phase 2: Identify Model and Version

Extract model name from user prompt. If version is unknown, query available versions:

```powershell
.\scripts\query_capacity.ps1 -ModelName <model-name>
```
```bash
./scripts/query_capacity.sh <model-name>
```

This lists available versions. Use the latest version unless user specifies otherwise.

### Phase 3: Run Discovery

Run the full discovery script with model name, version, and minimum capacity target:

```powershell
.\scripts\discover_and_rank.ps1 -ModelName <model-name> -ModelVersion <version> -MinCapacity <target>
```
```bash
./scripts/discover_and_rank.sh <model-name> <version> <min-capacity>
```
