Vercel AI SDK v7 Development Guide

Use this skill for AI SDK 7-specific implementation, migrations, and agent architecture. For AI SDK 6 projects, use ai-sdk-6. For unknown versions, use ai-sdk first to inspect node_modules/ai/package.json and local docs.

First Checks

1. Inspect package.json, lockfiles, and node_modules/ai/package.json.
2. Confirm the installed ai major version is 7 before applying this guide.
3. Search local docs first: node_modules/ai/docs/ and node_modules/ai/src/.
4. In monorepos, check app/package workspaces such as apps/*/node_modules/ai/ and packages/*/node_modules/ai/.
5. If local docs are missing or ambiguous, verify against ai-sdk.dev or the Vercel AI repository docs source before coding.

AI SDK 7 requires Node.js >=22 and AI SDK packages are ESM-only. Convert require() imports to import syntax before chasing downstream type errors.
