Use TypeSafe Jev for narrow judgments inside DeepSeek Harness — routing, classifying, scoring, verifying, reranking — instead of spending a model turn on them. Load this when a task turns on a decision with a small, fixed set of outcomes, or when you need a calibrated probability rather than prose.
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
# Jev in DeepSeek Harness Jev is a System One decision model. It does not write prose, explain, or generate code. It answers typed questions and returns calibrated probabilities. That constraint is the whole point: a judgment with a small, fixed answer set does not need a model turn, and paying for one is the most common waste in an agent loop. ## When to reach for it Use Jev when **all** of these hold: - the outcome is one of a small set you can name in advance; - you need a probability, a ranking, or a yes/no, not text; - you will branch on the answer in code. Typical shapes: which of these N tools is relevant; is this result relevant to the task; does this evidence support this claim; which team owns this ticket; how risky is this operation; which of these two sources is more authoritative. Do **not** use it to summarize, explain, draft, translate, or reason step-by-step. Those need a generative model, and Jev will return a selection where you wanted a sentence. ## The three primitives | Primitive | Answers | Returns | |---|---|---| | `noul` | yes/no | probability of true | | `choice` | one of a named set | the selection plus a distribution | …

How to install
mdr add perrylink/jevcore/typesafe-ai-dsh@sha256:429a288ee51ac4b3The line at the top of this page pins the label git:20260920.dbfada3, 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.
