Compare a narrow model grader with frozen human labels and inspect disagreement, bias probes, and repeated scoring stability. Use when building or changing a model-based evaluator.
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
# Evaluate a grader Freeze the human labels before running the grader. Use one narrow criterion with a written rubric and structured output. The grader must be able to return `unknown` or request human review. Keep human labels outside the judge workspace. Use `python3 -m helpers.evals.cli run-isolated-judge` to create a fresh child workspace containing only the named examples and current rubric. Run every revised rubric in a different fresh child. A child must not receive human labels, prior verdicts, captured verdicts, or later rubric versions. Preserve the isolation record with the verdicts. Use `helpers.evals.judges.evaluate_alignment` for the confusion table and disagreement set. Repeat at least one unchanged boundary example and use `repeated_label_stability` to measure scoring stability. Inspect: - every human and grader disagreement; - label imbalance; - an answer-order reversal when judging pairs; - a verbosity trap where a longer answer is not the better answer; - an ambiguous example that should produce `unknown`; and - whether the generator and grader are actually independent contexts. …

How to install
mdr add ai-analyst-lab/ai-analyst/evaluate-grader@sha256:64fb96fc239f015bThe line at the top of this page pins the label git:20260920.18d2675, 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.
