open-mercato/cezar ? reverse-engineered prompt

Build me a local web app for orchestrating coding agents across my repo.

I want to type a task, choose a workflow, and pick which agent should do each step, so I can run Claude Code, Codex, or OpenCode, and even mix them in one flow. The app should show everything live in the browser, like the current step, tool calls, output, tokens, cost, and diffs, so I can actually watch the agent work instead of guessing.

It should run each task in its own git worktree, support multiple runs at once, and queue the rest when it hits the limit. I also want an Autonomous mode where it keeps going without asking me questions, plus a way to hand it a GitHub issue and have it work from there, then leave me with a review screen and a draft PR instead of auto merging.

Make it work locally with no extra setup if possible, and if you need to, look up the current docs online for the agent tools and GitHub integration.
