benchmark-curator

Curate and version eval corpora for Agent Skills: case taxonomies, discovery/forced/negative controls, adversarial and regression cases, difficulty strata, holdout isolation, provenance, duplication, contamination, coverage balance, and benchmark hashes. Do not use to run the experiment or claim lift (skill-evaluator), to design the grading rubric (rubric-designer), to edit the skill (skill-creator), or to call leaked cases a clean holdout. Use to build an eval dataset, golden set, benchmark suite, regression corpus, or holdout.
