What problem does it solve? The AI SDK evolves rapidly, and model training data contains outdated APIs, deprecated parameters, and incorrect usage patterns. This Skill forces verification against bundled package docs and live documentation so generated code uses current APIs like ToolLoopAgent, inputSchema, and toUIMessageStreamResponse instead of deprecated patterns. ## Core Features & Use Cases - Verified API usage: Searches node_modules/ai/docs and source code, falling back to ai-sdk.dev, so answers reflect the installed SDK version rather than stale memory. - Agent and chatbot building: Guides creation of ToolLoopAgent-based agents with type-safe useChat consumption via InferAgentUIMessage, plus framework-specific integration patterns. - Migration and error fixing: The common-errors reference maps deprecated APIs (maxTokens, maxSteps, parameters, generateObject, tool-invocation parts) to their current replacements. - Use Case: A developer asks to add streaming chat to a React app. The Skill checks the installed ai package docs, fetches current model IDs from the Vercel AI Gateway, and generates code using DefaultChatTransport and typed tool parts. ## Quick Start Ask the assistant to build an AI chat feature with the AI SDK and have it verify the current APIs against the installed package documentation before writing code.
