jev-harness SKILL.md skillA
jev-harness from jzkk720/cubecloud-skills-bundle-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jzkk720/cubecloud-skills-bundle-kit/jev-harness@git:20260923.f4acf45Pins git:20260923.f4acf45 in mdr.lock. Pin the fingerprint instead.

Build, evaluate, and optionally evolve task-specific code and Jev decision pipelines with JevHarness. Use when a user wants a reusable Jev agent, a new task adapter, or trajectory-and-reward optimization; begin by clarifying the task and evaluation contract. Not for ordinary coding without a Jev workflow.
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
# JevHarness Turn the user's intended outcome into a runnable, measurable decision workflow: ordinary code prepares observations and enforces actions; Jev supplies structured judgments; an optional reflection model proposes improved pipelines offline. This is task-level pipeline optimization, not model-weight training. The deployed pipeline can retain Jev while removing the reflection model. ## Establish the task before building Read the user's request and existing authorized project material first. Reuse answers already given. Ask focused questions about missing information that would change the implementation or evaluation. Do not start a new task's implementation, generate its questions/criteria, access credentials, or run a paid experiment until enough of the following contract is known. Read-only inspection that helps identify those gaps can proceed. - **Outcome and scope:** What should improve, for whom, and what counts as success? Is this one decision per input or a multi-step episode? What is outside scope? …

How to install
mdr add jzkk720/cubecloud-skills-bundle-kit/jev-harness@sha256:34c6d8adefb2f295The line at the top of this page pins the label git:20260923.f4acf45, 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.
