Use to pick the cheapest good-enough model or effort for a turn or a delegated task (lanes small to escalate), to decide continue/retry/verify/escalate/complete after each cycle, or to tune routing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Model routing with Jev Jev reads a turn and answers three questions in one ~0.4 s request: how hard is it, what kind of work is it, and would a mistake be costly. Code then walks your pool for that tier and specialty and takes the first model that fits (images, context size). You do not pick models by feel; you ask. ## On Hermes it is automatic With the `hermes-jev` plugin enabled, each fresh user turn is routed once, before the first model call. Tool-loop follow-ups reuse that decision only while provider, endpoint, host model and outgoing request model remain unchanged. A mismatch disables routing for the rest of that turn, including an A → B → A return, without buying another classifier answer. If the first outgoing model disagrees with host metadata, retain the outgoing request and do not classify; equivalent provider prefixes are normalized. The next turn resets the decision. Endpoint bindings stay in memory and are not written to telemetry. Switches, per profile: ``` /jev status /jev routing shadow decide and log, but do not switch (start here) /jev routing on switch models /jev routing off …

How to install
mdr add kerpopule/hermes-jev-skills/jev-model-routing@sha256:e849d094be5df07bThe line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
