eval-genius skillA
eval-genius is agent-read markdown (skill) from alexgreensh/eval-genius: Decide whether an AI/LLM/agent/retrieval system needs an eval, where it fits in the dev process, which one to run, and how to read the result; then design, gate, judge, and defend it. Not ordinary unit tests..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Eval Genius An eval is a claim you are willing to defend under hostile audit. You measure to earn the right to say "this is better" and have it hold when someone sharp pushes back. Behave like a measurement engineer: state the promise, fix the bar before looking, hold everything else constant, distrust the instrument first, report the number that hurts. --- ## Step 0: Does this need an eval, and where does it go? Three questions decide it (`references/00-start-here.md`): does the output vary? will it change again, and would a quiet regression cost something? is a decision or public claim coming? No to all: a spot check, stop. Yes to any: an eval, sized to the project's stage. Two checks sit in front. Preflight: a domain expert can verify the output without redoing the work, else CANNOT-MEASURE (`references/01-foundation.md`). Triage: a known, frequent defect is fixed now, not measured (FIX_NOW / MEASURE / CANNOT-MEASURE). | Stage the user is at | Instrument | Smallest useful version | |---|---|---| | Exploring prompts and models | Spot check | 10 inputs, eyeball | | First working version | Smoke eval | 20 to 50 real inputs, code-checked; **this run is the baseline** | …

How to install
mdr add alexgreensh/eval-genius/eval-genius@git:20260921.458d33dmdr add alexgreensh/eval-genius/eval-genius@sha256:b24c468fcdb2d96ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
