调研方向

Start from examples/agent-workflow: read fetchSource and nextStep, then test/workflow.test.ts to see the assertions the new example must reproduce. Check integrations/langchain for createPaidFetchTool and the newcomer CI job that the new example must join. Done when a new examples/agent-workflow-langchain/ runs npm i && npm test with the same assertions and no API key, the README shows the transcript, and CI runs it.

描述

good first issue integration

examples/agent-workflow is an AI SDK agent that meets every outcome a seller can produce (paid, payee_mismatch, plan_exhausted, price_changed, unknown_merchant, no_challenge, transport failure) and handles each one as a value.

What: the same agent with LangChain.js / LangGraph, in examples/agent-workflow-langchain/. Reuse fetchSource and nextStep from the AI SDK example (copy them, or import them), wrap fetch_source as a LangChain tool, and drive it with a fake chat model so it runs with no API key (FakeListChatModel or similar).

Done when: npm i && npm test passes with the same assertions as test/workflow.test.ts, the README shows the transcript, and it is added to the newcomer CI job.

See also integrations/langchain (createPaidFetchTool).
