App Architecture & Manifest Configuration

When this skill applies

Use this skill when working with the foundational structure of a VTEX IO app — the manifest.json file, builder system, policy declarations, dependency management, service.json resource limits, and app lifecycle (link, publish, deploy).

• Creating a new VTEX IO app from scratch
• Adding a builder to an existing app
• Configuring policies for API access
• Troubleshooting deployment failures related to manifest misconfiguration

Do not use this skill for:

• Backend service implementation details (use vtex-io-service-apps instead)
• React component development (use vtex-io-react-apps instead)
• GraphQL schema and resolver details (use vtex-io-graphql-api instead)
