This task is part of the next AI SDK major release. Breaking changes are acceptable.
While breaking changes are acceptable, it is still encouraged to minimize unnecessary disruption for 3P consumers of the AI SDK. Providing deprecated aliases and automated migration logic can help ease the transition.
If renaming or modifying an exported function or type, provide a deprecated alias as a package-level export where feasible:
/** @deprecated Use `newFunctionName` instead. */
export { newFunctionName as oldFunctionName } from './new-module';
Only do this if it doesn't introduce meaningful technical debt. If it does, skip the alias — but check with the user first before making a clean break.
@ai-sdk/provider-utils)If modifying model message shapes (e.g. content part types in packages/provider-utils/src/types/content-part.ts):
@ai-sdk/provider-utils rather than removing immediately, if feasible. Mark deprecated types/members with a @deprecated JSDoc comment and a TODO note to remove in the following major version.packages/ai/src/prompt/content-part.ts — this file is the consumer-facing layer and should retain the old shapes in the Zod schemas so existing consumer code continues to compile with a deprecation warning. Include a similar note about deprecation and removal in the following major version.@ai-sdk/provider)The provider package defines the spec that provider implementers code against. It should generally not be modified outside of major versions, so keeping the spec clean and consistent is critical.
Breaking changes without maintaining temporary backward compatibility measures are more acceptable here than elsewhere, because the audience is smaller — far fewer developers implement their own providers than build features on top of the AI SDK.
Rules:
After implementing changes, update relevant documentation in content/docs/.
If the change requires consumers to update their code or migrate stored data, add a section to the latest migration guide:
content/docs/08-migration-guides/Add new or remove obsolete model IDs for existing AI SDK providers. Use when adding a model to a provider, removing an obsolete model, or processing a list of model changes from an issue. Triggers on "add model", "remove model", "new model ID", "obsolete model", "update model IDs".
Answer questions about the AI SDK and help build AI-powered features. Use when developers: (1) Ask about AI SDK functions like generateText, streamText, ToolLoopAgent, embed, or tools, (2) Want to build AI agents, chatbots, RAG systems, or text generation features, (3) Have questions about AI providers (OpenAI, Anthropic, Google, etc.), streaming, tool calling, structured output, or embeddings, (4) Use React hooks like useChat or useCompletion. Triggers on: "AI SDK", "Vercel AI SDK", "generateText", "streamText", "add AI to my app", "build an agent", "tool calling", "structured output", "useChat".
Guide for adding new AI provider packages to the AI SDK. Use when creating a new @ai-sdk/<provider> package to integrate an AI service into the SDK.
Create and maintain Architecture Decision Records (ADRs) optimized for agentic coding workflows. Use when you need to propose, write, update, accept/reject, deprecate, or supersede an ADR; bootstrap an adr folder and index; consult existing ADRs before implementing changes; or enforce ADR conventions. This skill uses Socratic questioning to capture intent before drafting, and validates output against an agent-readiness checklist.
