eval-harness SKILL.md skillA
eval-harness from a5c-ai/babysitter is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add a5c-ai/babysitter/eval-harness@git:20260601.da7723aPins git:20260601.da7723a in mdr.lock. Pin the fingerprint instead.

Evaluation harness for testing agent and skill quality through structured benchmarks, regression tests, and quality scoring.
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
- Define test cases with known-correct outputs - Run agent against each test case - Score: accuracy, completeness, relevance - Compare against baseline performance - Track performance over time ### 2. Skill Quality Testing - Verify skill instructions produce expected outcomes - Test edge cases and boundary conditions - Measure consistency across multiple runs - Check for harmful or incorrect outputs - Validate against ground truth ### 3. Regression Suite - Collection of previously-passing test cases - Run after any agent/skill modification - Flag regressions with before/after comparison - Maintain pass rate threshold (>= 95%) ### 4. Process Verification - End-to-end process execution with known inputs - Verify each phase produces expected outputs - Check task ordering and dependency satisfaction - Measure total execution time ## Quality Scoring ### Accuracy Score (0-100) - Correctness of output vs expected - Partial credit for partially correct outputs - Penalty for hallucinated or fabricated content ### Completeness Score (0-100) - Coverage of required output elements - Missing sections flagged and scored - Bonus for useful additional context ### Consistency Score (0-100) …

How to install
mdr add a5c-ai/babysitter/eval-harness@sha256:feafb468c646322cThe line at the top of this page pins the label git:20260601.da7723a, 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.
