Build an Agent with Eve: The Open Agent Framework
summary
Scaffolds a runnable agent with npx init and boots it locally with eve dev, then connects to Vercel AI Gateway, deploys to Vercel, and wires a Slack channel via Vercel Connect so the agent answers in Slack. Demonstrates OpenAPI connections (weather lookup), adds MongoDB query and a MongoDB mutate tool that requires human approval, shows built‑in observability when a tool call fails, runs deterministic evals plus LLM‑as‑judge, and uses serverless sandboxes and a stateless Workflow SDK to support long running tasks.
