“It ships a skill that lets a coding agent drive Rove itself, so the agents can now start each other and nobody has to be present.”

“Formerly HexAgent, now UniHarness: two names, one repository, and zero downloads in the week anyone last checked.”

Which one would each critic pick
| Critic | Rove | UniHarness | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.3 | Rove — Pick Rove if you want three agents working while your laptop is shut; pick a single terminal agent if you have never actually wanted three things happening at once. |
| El Crítico | 5.5 | 5.8 | UniHarness — One of the three supported targets is the local machine itself, which means the most convenient configuration is also the one with the boundary switched off. |
| El Profesor | 6.5 | 7.3 | UniHarness — A protocol separates the runtime from the machine it drives, and the runtime's keys, configuration and source are kept outside what the agent can read. |
| La Inversora | 5.8 | 5.3 | Rove — 116 stars, one author, permissive licence, and it schedules other companies' agents. The value it creates is billed by the vendors whose CLIs it launches. |
| La Jefa | 4.8 | 5.3 | UniHarness — Free across sixty engineers and able to run unattended, but the confined remote target is a third-party service, which is a supplier my security review has to process. |
| El Hacker | 7.5 | 6.8 | Rove — MIT, and any CLI I register becomes a task runner, so it is not limited to the four names in the description. There is no MCP client, and it does not need one. |
