We built Emendant to find the source sites an SDK upgrade will affect before the install. AI SDK 5 removed the ai/react entrypoint. In vercel-labs/ai-sdk-preview-attachments, Emendant found this affected import before the upgrade:

1
app/(preview)/page.tsx:10:1
2
import { useChat } from "ai/react";

The replacement comes from @ai-sdk/react. Emendant did not offer a patch for that repository. Its typecheck found other AI SDK 5 migration errors, and the replacement package was not installed. The tool does not change dependency versions or install a new dependency on the user's behalf, so it reported the result as inconclusive and withheld the patch.

For a separate repository built to demonstrate a fix, the AI SDK 5 CoreMessage to ModelMessage rename produced a patch with 3 added and 3 removed lines in one file. The patch was graded TYPECHECKED after these commands passed with AI SDK 5 installed:

1
npm install ai@5.0.0 --ignore-scripts --no-audit --no-fund
2
npm rebuild
3
npm run typecheck

Emendant is a local CLI for TypeScript and JavaScript. It reports changes that its feed describes for six npm packages: ai, openai, @anthropic-ai/sdk, langchain, @langchain/core and @google/genai. It does not claim to find every breaking change, it does not match Python, and it does not fix every finding. A scan makes no network request and does not upload source code.

The complete evidence includes the pinned repositories, the AI SDK 5 tagged source, the exact finding, the complete patch, the validation result and the limits:
