README

Durable Web Research Agent

A deep-research agent built on the [Vercel Workflow DevKit](https://vercel.com/docs/workflow). Ask a question and the app runs a **durable, resumable workflow** that searches the web, fetches source pages, extracts cited findings, and synthesizes a grounded research brief — streaming each step to the browser in real time.

Because the orchestration runs as a workflow, every step is checkpointed: the run survives restarts, retries failed steps, and can be reconnected to from any client via its `runId`.

How it works

question ──▶ searchWeb ──▶ fetchSourcePage ─┐
                                            ├─▶ extractFindings ──▶ synthesizeReport ──▶ cited brief
            (per source, up to 5)  ─────────┘

workflows/research-workflow.ts — the durable orchestrator ("use workflow"). Fans out over search results and streams tool-call / tool-result parts to the UI.
workflows/research-steps.ts — individual durable steps ("use step"): DuckDuckGo search, page fetch + HTML-to-text, and finding extraction.
workflows/synthesize.ts — final step that turns findings into a structured, cited report.
app/api/research — starts a run and returns its runId.
app/api/run/[runId] — polls run status and the final return value.
app/api/readable/[runId] — streams workflow events to the UI as Server-Sent Events.

Tech stack

Next.js 16 (App Router)
Vercel Workflow DevKit (workflow, @ai-sdk/workflow)
AI SDK v7 via the Vercel AI Gateway — uses plain provider/model strings (anthropic/claude-sonnet-4.6, anthropic/claude-haiku-4.5)
Tailwind CSS v4, TypeScript

Web search uses DuckDuckGo's HTML endpoint, so **no search API key is required**.
