summary

Converts a local coding agent into a durable, production-ready workflow using Vercel’s open‑source Workflow DevKit and the AI SDK, with Next.js and a sandbox VM for tool execution. Marks LLM calls and tools as steps with the use step marker, exposes resumable streams so clients can reconnect, and adds observability via a local/web UI that shows step inputs/outputs. Demonstrates sleep and webhook human‑in‑loop tools, deployment to Vercel preview, and claims over 1,000,000 workflows run daily internally; the demo deploys and resumes successfully.
