Design, implement, and improve software using TypeSafe AI's Jev. Use for Jev questions, evidence representation, typed judgment composition, API integration, and diagnosis of Jev-backed behavior.
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 Developer Build the requested software behavior using Jev where semantic judgment supplies information the program needs. Jev evaluates supplied information and returns typed judgments. The SDK handles transport and response types; calling software prepares evidence, performs exact calculations, resolves IDs, and applies results. Jev does not retrieve external evidence, generate free-form content, or execute selected operations. ## Design from the Required Behavior Start from the required output or effect and available inputs. Identify the unresolved meaning that changes the result and the information Jev must read to judge it. Express the subject, conditions, and evidence relationships in the request. Assign known transformations, exact calculations, and data joins to code where appropriate, so the remaining semantic judgment has the context it needs. Choose judgment units and answer spaces that preserve the information needed to construct the result. Existing values can become candidates, relations can be judged over pairs, and structure can be assembled from boundary or component judgments. A complex output need not require a complex model answer. …

How to install
mdr add smturtle2/codex-skills/jev-developer@sha256:0378063c0102935eThe line at the top of this page pins the label git:20260920.42ced1e, 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.
