UserNine Claude Skills for evaluating AI systems and the skills you install to do it. Every one has a stated refusal.

Indexed Skills (9)
automation-break-even
Convert model accuracy into an honest estimate of work saved, cost saved, or headcount impact. Use for AI business cases, ROI estimates, automation proposals, or any claim of the form "the model is X% accurate so it saves X% of the work". Measures the real review costs first and refuses to multiply.
baseline-before-model
Force a non-model baseline to be built and measured before any LLM is proposed for a task. Use when scoping an AI feature, choosing a model for extraction, lookup, classification or routing, or when someone asks which model to use for a job. Refuses to recommend a model until the boring alternative has a number.
eval-set-builder
Build an evaluation set from real traffic and check whether it is large enough to support the error budget being claimed. Use when someone wants to measure model accuracy, certify an error rate, decide if a model is safe to deploy, or asks "how many test cases do we need". Refuses to certify a budget the sample cannot support.
llm-judge-auditor
Audit an LLM-as-judge setup for self-preference, position bias, and lack of human agreement before its scores are trusted. Use when a model grades model output, for pairwise preference evaluations, automated scoring, or when someone reports win rates from an AI judge. Refuses to accept judge scores with no measured human agreement.
model-bakeoff
Compare two or more models on the same task and decide whether any observed difference is real. Use when choosing between models or providers, running a bakeoff or shootout, checking if a new model beats the current one, or interpreting benchmark results. Uses paired tests and corrects for multiple comparisons. Refuses to name a winner on noise.
prompt-and-grader-audit
Read an eval's prompt and its grader together as a single artefact and find where they contradict each other. Use when eval scores look wrong, a model is being punished for correct behaviour, scores are suspiciously low, or before trusting any eval result. Refuses to accept a score where the prompt and grader disagree.
skill-actually-works
Measure whether an installed skill changes the output at all, by running the same tasks with it enabled and disabled. Use when auditing an installed skill library, deciding which skills to keep, or when someone claims a skill improved results. Refuses to credit a skill with an effect it cannot demonstrate.
skill-degradation-check
Test whether a skill invents data when its inputs, tools or API connections are missing, instead of reporting the gap. Use before trusting a skill on client or production work, when a skill produces suspiciously complete output, or when auditing a skill library for honesty. Refuses to pass a skill that fills gaps silently.
skill-safety-review
Statically review a SKILL.md or agent skill before installing it, flagging credential access, exfiltration, instruction override, and review-evasion patterns. Use before installing any third-party skill, plugin or agent extension, or when asked whether a skill is safe. Read-only. Never executes what it scans.
