What Jev is not
Jev does not generate prose, code, or free-form tool strings — surrounding code owns loops and safety.
Hard boundaries
| Expectation | Reality |
|---|---|
| Chat / long prose | Use an LLM |
| Invent tool names | Use Choice over an allow-list |
| OpenJev ≈ Jev accuracy | OpenJev/SemIf ≠ TypeSafe weights |
| Screenshot-native vision by default | Not the default System One story — re-check docs |
Ecosystem
See /ecosystem/ for TypeSafe, Gateway, SemIf, computer-use, and Unclutter. SimpleJev stays off nav until a public URL is locked.
