Evidence and scope
Documented records the linked documentation or source. JevHunt has not independently run or benchmarked this project.
jev-opus runs Claude Code on `claude-opus-5-5`, either your normal interactive `claude` with an "Opus 5.5 · Jev" entry in `/model`, or a session it drives itself. The [TypeSafe Jev] System-1 reflex picks the effort level when a prompt arrives, then again after every tool batch, before Claude's next API call. Reading files runs at `low`. A failing test raises the next step to `high`. Once tests pass, it drops back down. All of this happens inside one prompt.
