# 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. ## Install Use the project's package manager and install only packages needed by the task: ```bash bun add ai @ai-sdk/react bun add @ai-sdk/openai # or the provider already used by the project ``` For durable agents, add `@ai-sdk/workflow` and `workflow`. For harness agents, add `@ai-sdk/harness`, one harness adapter, and a sandbox provider. ## Core v7 Patterns | Task | Prefer in AI SDK 7 | | --- | --- | | Text generation | `generateText` / `streamText` | | System prompt | top-level `instructions`, not `system` | | Structured output | `output: Output.object(...)` on text fun...
