## What it does

This skill reviews the parts that define a VTEX IO app: `vendor`, `name`, `version`, builder declarations, `dependencies`, `peerDependencies`, and `billingOptions`. It connects the manifest with the capabilities the app actually owns.

It helps choose builders for `node`, `graphql`, `react`, `admin`, `store`, `messages`, `pixel`, and `masterdata`, and flags cases where a separate app should own a capability. It also targets link and publish failures caused by manifest-level contract decisions.

An app that ships backend or GraphQL code without the matching builder in `manifest.json` has an incomplete contract, so the platform ignores that capability.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add vtex/skills --skill vtex-io-app-contract -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add vtex/skills --skill vtex-io-app-contract -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/vtex-io-app-contract/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add vtex/skills --skill vtex-io-app-contract -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install vtex/skills vtex-io-app-contract
```

2. **Manually: put the files in place**
- File: `.github/skills/vtex-io-app-contract/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add vtex/skills --skill vtex-io-app-contract -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/vtex/skills --path skills/vtex-io-app-contract
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/vtex-io-app-contract/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add vtex/skills --skill vtex-io-app-contract -a opencode
```

### 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/vtex/skills/tree/HEAD/skills/vtex-io-app-contract/SKILL.md

## When to use it
- define a VTEX IO app contract in `manifest.json`
- match builders to the app’s shipped capabilities
- choose between `dependencies` and `peerDependencies`
- trace link or publish failures to the manifest
- check app identity and version before publishing

## Example prompts
- Review `manifest.json` for this VTEX IO app and recommend the builders it should declare.
- Find capabilities that should move into a separate app because the manifest mixes unrelated responsibilities.
- Investigate this publish failure by checking `dependencies`, `peerDependencies`, `billingOptions`, and the app version.
