Runs an autonomous review-and-fix improvement loop over any code target — a skill, plugin, module, or directory — using a reviewer the user names: any installed skill or agent. Keeps a cross-round findings ledger, escalates when fixes stop converging, and guards scope mechanically. Use when asked to 'improve this code until review passes', 'run an improvement loop with <reviewer>', or to iterate review-and-fix with a specific reviewer. For skills prefer the skill-improver entry; for a branch…
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
# Code Improver Improve any code target by running `/code-improver:improve` — a dynamic workflow that loops the named reviewer and a fixer subagent until a review reports zero critical/major findings, then strips its own residue. The loop, its ledger, and its guards live in the workflow; this skill collects the three inputs the generic entry requires and relays the outcome. ## Starting the loop The user provided: `$ARGUMENTS` (if empty, take the details from the conversation). ### 1. Collect the three required inputs — no guessing 1. **Target**: the absolute path to the directory under improvement. Resolve relative paths against the working directory; verify the directory exists. 2. **Reviewer**: the installed skill or agent that performs every review. The user must name it — there is no default and no bundled reviewer. Determine the kind: - a namespaced agent (e.g. `plugin-dev:skill-reviewer`) → `"kind": "agent"` - an installed skill (e.g. `pr-review-toolkit:review-pr`) → `"kind": "skill"` If the name could be either, check the session's skill listing; if still ambiguous, ask the user. If no reviewer was named, ask — do not pick one. …

How to install
mdr add trailofbits/skills/code-improver@sha256:a4e33a24c853da3dThe 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.
