“Its own showcase hands it a $5,000 budget and a Ritz-Carlton booking, which is one way to find out whether an agent stops.”

Which one would each critic pick
| Critic | Agent TARS | ccswarm | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.3 | no preference |
| El Crítico | 5.5 | 5.5 | no preference |
| El Profesor | 6.0 | 6.3 | ccswarm — The flow declares plan, a consensus stage, implementation, review and fix as separate steps, which puts verification inside the loop rather than after it. |
| La Inversora | 5.3 | 5.0 | Agent TARS — A ByteDance research project: no pricing, free remote operators, weights on Hugging Face and ModelScope, and the business is Doubao tokens on Volcengine; strategic projects get shelved, not sold. |
| La Jefa | 5.0 | 5.8 | ccswarm — Every run leaves an NDJSON trail we can replay, diff and roll back, and there is still no console, no single sign-on and no per-seat anything. |
| El Hacker | 7.0 | 5.8 | Agent TARS — Apache-2.0, --provider --model --apiKey on the command line, MCP servers mounted as tools, a UI TARS SDK for building my own GUI agent, and Midscene if I only want the browser half. |
