What it is
A community-curated list of open-source projects built around TypeSafe Jev / System One typed-decision models, grouped by use: agents, browser use, SDKs, dev tools, research, learning, apps, and alternatives.
How it uses Jev
The README does not describe how Jev is used in code; it only catalogs third-party projects that use Jev for decisions such as model routing, tool-call gating, skill selection, and agent control.

Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
