“An Electron app whose entire job is to open terminals, which is the most modern thing to happen to the command line this year.”

Which one would each critic pick
| Critic | CowAgent | FleetCode | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.3 | FleetCode — Pick it if parallel agents keep colliding in one checkout; pick a single branch and a terminal if you have never actually needed two at once. |
| El Crítico | 6.0 | 6.3 | FleetCode — The row records that the parallel sessions do not coordinate with each other, so multi-agent here means several agents unaware of each other rather than a team. |
| El Profesor | 5.8 | 6.5 | FleetCode — Sessions resume using the coding CLI's own session identifier, which delegates continuity to the vendor rather than reimplementing it, and inherits whatever that identifier guarantees. |
| La Inversora | 6.5 | 6.0 | CowAgent — A rename from chatgpt-on-wechat carries 46k stars into a new brand, and the business is LinkAI, which sells hosting, role-based access and private deployment on top. |
| La Jefa | 5.5 | 5.3 | CowAgent — Free software, but the team features live in a separate LinkAI product, and five model categories routed to five vendors mean five data-retention reviews instead of one. |
| El Hacker | 7.5 | 7.3 | CowAgent — MIT, a Custom provider row for local models or a proxy, one mcp.json with stdio and SSE that hot-reloads, and skills installable from GitHub or ClawHub with a slash command. |
