Automated README summary
Automatically summarized from the README on 28 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A self-hosted model router for coding agents and OpenAI-compatible clients. It assesses each new task with TypeSafe's Jev, then applies YAML rules to pick a model and reasoning effort from your upstream's pool, binding a session to one model.
How it uses Jev
On a fresh session resolve, Jev receives a bounded state of request excerpts and computed facts and assesses the task. Its result feeds YAML policy to select model, provider, effort, and limits, returned as a binding. If Jev fails, strict admission uses the alias's admission_fallback or refuses with NO_SAFE_ADMISSION.
Primitives:choicescorenoul
Technique worth stealing
Resolve the model once per session before the client sizes its history, then keep the binding stable across the tool loop.
Try it
uv sync --locked, edit quickstart.local.yaml, then uv run jev-router -c quickstart.local.yaml serve.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
