calibrate-difficulty SKILL.md skillA
calibrate-difficulty from understudylabs/orchestra-agent-tools is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add understudylabs/orchestra-agent-tools/calibrate-difficulty@git:20261020.17ad730Pins git:20261020.17ad730 in mdr.lock. Pin the fingerprint instead.

Measure per-band model headroom from a local, source-bound run artifact before investing in training.
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
# Calibrate difficulty Use an existing local run artifact with explicit generic `band` labels. The artifact is hashed and the report records that source binding. This is a deterministic screening step: it makes no provider calls, never reads holdout or customer data, and does not infer bands from benchmark-specific task IDs. ```bash npm run build node scripts/difficulty-calibration.mjs --run path/to/synthetic-run.json --out report.json ``` Scores at or above `0.95` are saturated only when the band has at least 10 scored rows; insufficient sample takes precedence and remains `caution`. Only sufficiently sampled bands below the threshold are `measurable` and `invest`. Keep fixture, split, scoring protocol, and source hash visible, and use dev/train data for decisions—never holdout data. ## Safety Gates - Use only a frozen, source-bound train/dev run. Never use holdout rows or make provider calls from this calibration step. - Predeclare the saturation threshold and minimum sample. An undersized band is `insufficient_sample` even when its observed mean is perfect. - Treat the report as a spend-routing screen, not promotion evidence or proof …

How to install
mdr add understudylabs/orchestra-agent-tools/calibrate-difficulty@sha256:47675b4473234549The line at the top of this page pins the label git:20261020.17ad730, 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.
