Runs an autonomous review-and-fix improvement loop over a Claude Code skill until a review comes back clean, with a cross-round findings ledger, escalation when fixes stop converging, and a mechanical scope guard. Reviews are performed by the plugin-dev skill-reviewer agent. Use to fix skill quality issues, iteratively refine a skill, or resume a loop after an escalation ('fix my skill', 'improve this skill until it passes review', 'skill improvement loop'). NOT for a one-time review — use the…
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 Improve a Claude Code skill by running `/code-improver:improve` — a dynamic workflow that loops a reviewer and a fixer subagent until a review reports zero critical/major findings, then strips its own residue. This entry point wires the loop to the `plugin-dev:skill-reviewer` agent, so the **plugin-dev plugin must be installed** (marketplace `claude-plugins-official`). The loop, its ledger, and its guards live in the workflow; this skill resolves the target and relays the outcome. ## Starting the loop The user provided: `$ARGUMENTS` (if empty, take the target skill from the conversation). ### 1. Resolve the skill path 1. If the input ends with `/SKILL.md` and the file exists, use its directory 2. If the input is a directory containing `SKILL.md`, use that path 3. Otherwise `Glob(pattern="**/SKILL.md")` and filter by skill name or path substring: - **Multiple matches:** ask the user to choose - **No matches:** report the available skills - **Single match:** proceed ### 2. Resolve the loop script The loop is the dynamic workflow `workflows/improve.js` in this plugin. Launch it by …

How to install
mdr add trailofbits/skills/skill-improver@sha256:5764d6f51c5cd2e9The line at the top of this page pins the label git:20260824.1004934, 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.
