ACE

One orchestrator agent plans and delegates without writing code itself; ten specialist subagents implement and judge the work, and a twelfth agent runs cross-model review across up to four independent critics. Every item moves through plan, work, audit and merge stages, and a failed audit sends the item back to work rather than blocking the pipeline.

It can run several feature streams in parallel, each in its own self-merging git worktree, through ace start, ace autorun or ace swarm start.

The overseer defaults to Claude Opus, but the crew can run end-to-end on a low-cost DeepSeek API key alone; it targets Fedora Silverblue or Arch with Node, Python and Go, and installs entirely user-local without root.
