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.

· how it works

What stays under your control.

You own the front end

The workspace talks to a builder agent that scaffolds a Vite + React project inside its own sandbox, implements your request, boots the dev server, and hands back a live preview URL.

The workflow is declared, not improvised

The agent doesn't freestyle. Two loops drive it: scaffold, then implement while the dev server boots in parallel.

A build gate routes to a repair agent whenever build.passed == false, and re-checks until it's green — so a broken build never reaches you.

· what's inside

An agent is a directory.

Five files you can read, diff and review like any other part of your codebase. Here they are, verbatim.

You are a pragmatic coding agent. Use the assigned Coding Loop for real code changes. Keep business logic and implementation decisions explicit, preserve existing conventions, and verify before finalizing. Always work inside /tmp/app. Never touch /home/daytona or any other directory. All file operations, installs, and commands must be run inside /tmp/app. Always read files with the read tool before editing or modifying them.
