measured-change from kamiazya/whiteboard is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Build the measuring instrument before changing anything whose effect you cannot see by reading the diff — quality scoreboards (pinned aggregate metrics) and performance benchmarks (pnpm bench, interleaved runs). Use for optimisation, layout/routing quality, heuristic tuning, or any change where "did that help?" is a real question — AND for a structural change (moving work off a thread, unifying a pipeline, making a mistake uncompilable), where the numbers SIZE a benefit that end-to-end timing…
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
# Measure before you change it Some changes announce themselves in the diff. A heuristic, a cost model, a search, an optimisation does not: it is correct-looking code whose worth is entirely in numbers nobody has taken. For those, **the instrument comes first, in its own commit, and the change is judged by it.** Which numbers, though, follows from what kind of benefit you are claiming — and a structural change (work moved off a thread, a pipeline unified, a mistake made uncompilable) needs different ones from a speed-up. That is the next section, and it comes before everything else here. This is not a preference. Across one routing/performance batch the instrument rejected **three separate changes that were obviously right**: - per-blocker detours — fixed 10 more defects, added 16 crossings; crossings are a higher tier, so it was a bad trade in the project's own currency - a per-group placement cache — measured *slower* in all three rounds; the cached groups held two or three items and the key cost more than the work - an excess-length penalty tier — a new cost term that argued well and moved no debt metric the corpus pins …

How to install
mdr add kamiazya/whiteboard/measured-change@sha256:702ecb686c778d45The line at the top of this page pins the label git:20260910.514441f, 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.
