What it is
JevRouter routes agent requests across models, subagents, skills, MCP tools, CLIs, and plugins. It uses Jev Choice decisions to pick the next capability, while the host enforces availability, permissions, risk, and confirmation before execution.
How it uses Jev
Jev answers one typed Choice question over a candidate set of capabilities. JevRouter uses the returned probabilities to select a candidate, then applies policy filters and confirmation gates. Filtered candidates are never re-normalized; raw provider responses are preserved.
Primitives:choice
Technique worth stealing
Use Jev for fast, calibrated routing decisions while keeping execution and fallback in the reasoning model.

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.
