What it is
Jev judges new context once, above a configurable size gate. Yoshi applies the validated omissions while keeping the protocol intact, then forwards the request to Anthropic or OpenAI and streams the response back unchanged.
What the README says it does
- Asks Jev, one span per request, with up to eight requests in flight. Each
- Applies only validated omissions. A removed span becomes an explicit
- Serves both protocols on one loopback listener: the Anthropic Messages
From the project’s README.
Where the decision sits
yoshi runs its own weights or its own runtime rather than calling a hosted API, so its decisions do not depend on a vendor being up or on a key being funded. The trade is that the model is now yours to keep current.
How active it is
Created 2026-09-18, last pushed 2026-09-18, 31 stars and 3 forks when we read it on 2026-11-02. Everything in this category is weeks old at most, so a stale push date means something different here than it would on a mature project. Check the repository before you depend on it.

We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
