session-measurement skillA

session-measurement is agent-read markdown (skill) from jovesun-lab/whetstone: Measure an AI agent's per-session performance on a small, stable metric set and track it as a trend over a long run, so you can tell whether a change — a new model version, a new operating frame/scaffolding, a new skill set — actually improved the agent or regressed it. Use this whenever someone wants to benchmark, score, grade, or track an agent's performance across sessions; compare two agent versions or frames; build a "did this change help?" scorecard; or turn a finished session into a logge.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add jovesun-lab/whetstone/session-measurement@git:20260820.a3d59c6
Exact content
mdr add jovesun-lab/whetstone/session-measurement@sha256:96b20ee607fac422

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
