Vercel AI SDK — Patterns & Migration Guide
SkillSkill
Stop writing broken AI apps. Current APIs, migration table, agent patterns.
About
The Vercel AI SDK changes fast and your training data is already stale. This skill enforces correct API usage, provides the exact old→new migration table for v5 breaking changes (parameters→inputSchema, maxTokens→maxOutputTokens, generateObject→generateText, useChat transport changes), and shows how to fetch current model IDs at runtime so you never hardcode stale strings.
Includes: complete API migration table, tool definition patterns, generateObject replacement, useChat v5 changes, ToolLoopAgent pattern for type-safe agents, and a quick diagnosis flow for typecheck failures.
For any developer or agent building AI-powered apps with the Vercel AI SDK.
