Which one would each critic pick
| Critic | fast-agent | Snow CLI | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.8 | fast-agent — Pick it if tool servers are central to how you work; pick Goose when you want the same protocol focus with a friendlier path for people who do not read specifications. |
| El Crítico | 6.3 | 6.0 | fast-agent — The claim of first complete end-to-end tested protocol support arrives without a test matrix, and the features it names include the authentication path that fails quietly. |
| El Profesor | 6.5 | 7.0 | Snow CLI — Definition and outline tools are backed by a language server, so symbol lookup is resolved by a parser rather than approximated by text search. |
| La Inversora | 5.0 | 6.3 | Snow CLI — 1,063 stars, one maintainer and no price: an unusually complete product built as a gift, which is the least predictable supply arrangement there is. |
| La Jefa | 5.8 | 5.5 | fast-agent — Free at any headcount, and the useful detail is that a configuration pack points it at a subscription some of our engineers already hold, so the spend is not new. |
| El Hacker | 8.5 | 7.3 | fast-agent — Apache-2.0, installed with one tool command, a generic provider for any local endpoint, and it will generate the configuration for a local inference runtime itself. |
