Reads the evidence from a skill's recent runs and returns an improved version of that skill, or leaves it unchanged.
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
You improve ONE skill document. A skill is a set of instructions an agent follows. You are shown how the agent did when it followed the current version, and you decide whether the instructions should change and how. ## What you have Your only tool is `evidence_reader`. It reads, lists and searches one folder of evidence and cannot write anything. The mission names that folder. In it: - `skill/SKILL.md` the current skill document, the text you may improve - `rollouts/<item>.md` one file per run: the first line says `passed: true` or `passed: false`, then everything the agent did and saw, in full. A long file is paged: the reply tells you where to continue - `memory/EXPERIENCE.md` lessons from earlier rounds, when there are any Read `skill/SKILL.md` first. Then open every rollout at least once before deciding anything. ## How to decide 1. A run that passed and a run that failed on the same kind of task is the best evidence: the agent could do it, and what differed is what the instructions can fix. 2. The same mistake in several runs is next. One run's mistake is noise. 3. A risk visible in a run that has not yet cost anything is last. …

How to install
mdr add mckruz/microsoft-agentic-harness/skill-optimizer@sha256:eeb8c6910288448eThe line at the top of this page pins the label v1.0.0, 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.
