What it is
A Jev-style skill router for OmO. A frozen Qwen2.5-0.5B plus a small option-attention head scores the whole skill catalog against the user's prompt, and an OmO extension trims the skill block to the top-K.
How it uses Jev
Jev scores every catalog skill (name: description options) against the user prompt in one forward pass; the extension keeps the top-K skills in the system prompt, preserves explicit $skill:name invocations, and returns the prompt unchanged on any error (fail-open).

Technique worth stealing
Cache catalog option embeddings once, then train only a small option-attention head over a frozen encoder.
Try it
docker compose up --build -d in server/, then copy extension/jevlike-router.js to ~/.omo/extensions/.
