Improve, test and maintain Claude Code skills. Modes: `fix` runs a skill's eval cases and fixes what the failed answers show is missing; `improve` hill-climbs a 10-dimension quality rubric with blind scoring and an A/B comparator; `score` rates a skill without editing it; `freshen` verifies the skill's external references online and applies updates; `trigger` measures and tunes how reliably the description fires; `outcome` runs eval cases with and without the skill; `floor` measures what a…
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
# Skill Improver `/skill-improver <mode> <target> [--opts]`. `<target>` is a skill name, a SKILL.md path, `--all`, or a glob (`'vllm-*'`). No mode → **Auto**. No target (except `ages`, `batch`) → ask. | Mode | Does | Read first | |---|---|---| | Auto | Decides which modes the skill needs, runs them | §Auto | | `fix` | Runs the skill's eval cases, fixes what the failed answers show is missing | §Fix | | `improve` | Keep/discard loop on the 10-dimension rubric | `references/improve-loop.md`, `references/quality-rubric.md` | | `score` | Rubric score, no edits | §Score | | `freshen` | Verifies every `sources.md` row online, applies verified updates | `references/freshen-patterns.md` | | `trigger` | Measures and tunes the description's trigger rate | `references/trigger-patterns.md` | | `outcome` | Runs the skill's eval cases with vs without it (`claude plugin eval`) | §Outcome | | `floor` | Measures what a bare model already knows about the subject | `references/floor-patterns.md` | | `ages` | Fleet table of verification age vs last change | §Ages | | `batch` | Runs `improve`, `freshen` or `trigger` over many skills | §Batch | …

How to install
mdr add air-gapped/skills/skill-improver@sha256:80731b5c0176594dThe line at the top of this page pins the label git:20261019.f156b14, 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.
