harness-optimizer SKILL.md skillA
harness-optimizer from tcuzzo/backs-aios-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tcuzzo/backs-aios-skills/harness-optimizer@git:20261024.6bd1e8dPins git:20261024.6bd1e8d in mdr.lock. Pin the fingerprint instead.

Improve an evaluation or agent harness through bounded baseline-versus-candidate measurements, holdouts, leakage checks, and durable evidence without benchmark overfitting.
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
# Harness Optimizer Use this skill to sharpen a harness's routing, truth assembly, evidence capture, or evaluation quality. The goal is a measured platform improvement, not a higher score on a memorized benchmark. ## Establish the experiment 1. State the capability being improved and the layer under test: truth source, routing, control flow, prompt/rendering, or evidence handling. 2. Capture a baseline using the current system and fixed inputs. Record configuration, dependency versions, timing, errors, and per-case outcomes. 3. Freeze an evaluation split before tuning: - **smoke** for basic viability; - **search** for iteration; - **canary** for known fragile behavior; - **holdout** for unseen generalization; - **leakage** for overlap and benchmark-specific shortcuts. 4. Include balanced domain and mixed-domain cases when the harness serves more than one domain. ## Change one confound at a time - Separate truth-source changes from routing changes. - Separate control-flow changes from prompt or rendering changes. - Keep providers, models, and runtime settings fixed unless that layer is the subject of the experiment. …

How to install
mdr add tcuzzo/backs-aios-skills/harness-optimizer@sha256:e20cc4bd64fd6b0dThe line at the top of this page pins the label git:20261024.6bd1e8d, 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.
