Vibe coding agent
A Lovable-style app builder you own end to end. Type a prompt, get a running app on a live preview URL, publish when it's ready.
What do you build with?
Paste this into Claude Code — it does the rest
Scaffold the Polpo vibe-coding-agent starter — the builder agent, its two loops and its function tools — then run it and hand me the preview URL.

Anatomy of one agent
One agent directory wires the whole thing — agent.jsondeclares the model, tools and loops, while instructions.mdkeeps behavior readable. Edit any piece in a diff; nothing is hidden in a dashboard.

Six files — that's the whole backend.
No dashboard to configure, no service to stand up — the agent config, its instructions, two loops and two tools are files you read, diff and review like any other part of your codebase.
