Record run metadata, traces, judges, artifacts, and limitations.</li>\n<li>Check Eval validity and distinguish Skill Defect, Eval Defect, Infrastructure Defect, and Unknown.</li>\n<li>Report results, evidence states, benchmark/regression conclusions, blocked checks, and recommended actions; add a regression case only after a real failure has a confirmed root cause.</li>\n</ol>\n<h2>Constraints</h2>\n<ul>\n<li><code>skill-up</code> is the primary Eval Engine. Trace checks are a deep-evidence layer; do not create another Engine, Judge, Benchmark, or Quality Score.</li>\n<li>A similar output is not observed trigger evidence; missing <code>skill.selection</code> trace evidence is <code>BLOCKED</code>.</li>\n<li><code>skill-up validate</code> is not runtime semantic validation. Static checks, CLI smoke, Project Done, and one semantic observation cannot be promoted automatically to release or business claims.</li>\n<li>Do not modify the Skill or enter an unlimited optimization loop. Keep Benchmark (with/without Skill) separate from Version Regression (previous/current).</li>\n<li>Use <code>unknown</code> for unknown values; preserve <code>NOT_RUN</code>, <code>UNASSESSED</code>, <code>BLOCKED</code>, or <code>INSUFFICIENT_EVIDENCE</code> when evidence is incomplete.</li>\n</ul>\n<h2>Reference files</h2>\n<ul>\n<li>Read <code>prompts/skill-evaluation.md</code> for the complete execution and report contract.</li>\n<li>Read the target Skill's <code>evals/</code> and its fixtures before selecting a judge.</li>\n<li>Use repository governance contracts and trace rules as optional deep references, never as private dependencies of a copied Skill.</li>\n</ul>\n<h2>Common pitfalls</h2>\n<ul>\n<li>Treating <code>skill-up validate</code> or a dry-run as proof of runtime or semantic effectiveness.</li>\n<li>Calling a missing trigger event a negative result instead of <code>BLOCKED</code>.</li>\n<li>Mixing with/without Skill benchmarks with previous/current version regression.</li>\n</ul>\n<h2>Best practices</h2>\n<ul>\n<li>Start with the smallest deterministic case that demonstrates the intended behavior.</li>\n<li>Record the exact run identity, judge, environment, unavailable evidence, and limitations.</li>\n<li>Convert only confirmed real failures into regression cases, and preserve the original evidence.</li>\n</ul>\n<h2>Progressive disclosure</h2>\n<ul>\n<li>Read <code>prompts/skill-evaluation.md</code> before producing the report.</li>\n<li>Read the target Skill's own <code>evals/</code> first, then load fixtures, examples, and scripts as needed.</li>\n<li>Repository Evaluation Contract and local trace rules are optional deep references; an independently installed Skill must not depend on their private files.</li>\n</ul>\n<h2>Pre-delivery checklist</h2>\n<ul>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Every conclusion maps to a case, judge, and evidence state</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Run metadata, environment, model, and unexecuted checks are explicit</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Skill/Eval/Infrastructure/Unknown classifications are not conflated</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> Trigger, benchmark, regression, and Quality Score boundaries are clear</li>\n</ul>\n","files":[{"path":"agents/openai.yaml","sizeBytes":391,"isText":true},{"path":"evals/cases/basic-success.yaml","sizeBytes":622,"isText":true},{"path":"evals/cases/edge-incomplete-input.yaml","sizeBytes":424,"isText":true},{"path":"evals/cases/edge-no-second-engine.yaml","sizeBytes":471,"isText":true},{"path":"evals/eval.yaml","sizeBytes":381,"isText":true},{"path":"prompts/skill-evaluation.md","sizeBytes":2834,"isText":true},{"path":"SKILL.md","sizeBytes":4169,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
