“Remote control lets you reach it from Feishu, so the agent working at your desk can be supervised from someone else's phone.”

Which one would each critic pick
| Critic | NanoClaw | Open Cowork | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.3 | Open Cowork — Pick it if your work ends in documents and spreadsheets; pick a coding agent if it ends in a pull request. |
| El Crítico | 6.3 | 6.5 | Open Cowork — Commands run inside a WSL2 or Lima VM, and the GUI operation that drives your desktop applications does not, so the containment stops where the reach begins. |
| El Profesor | 7.0 | 6.3 | NanoClaw — One host process routes user to group to session, two SQLite files per session with exactly one writer each replace IPC, a container polls them, and a sweep runs every sixty seconds. |
| La Inversora | 6.5 | 6.5 | no preference |
| La Jefa | 5.8 | 5.5 | NanoClaw — Credentials never enter the container thanks to OneCLI's vault with per-agent policies and rate limits, a good questionnaire page; Docker Desktop on sixty laptops and default-on diagnostics are not. |
| El Hacker | 7.5 | 7.3 | NanoClaw — MIT, /add-ollama-provider per agent group, ANTHROPIC_BASE_URL in .env for any compatible endpoint, channels and providers kept on their own branches, and the fork is the intended unit of ownership. |
