Runs an autonomous review-and-fix improvement loop over the current branch's changes until a PR review comes back clean, scoped mechanically to the directories the branch touched. Reviews are performed by an installed PR-review skill (default: pr-review-toolkit's review-pr). Use to fix review findings on a branch before opening or updating a pull request ('clean up this branch', 'fix this PR until review passes', 'run review-and-fix on my changes'). NOT for a one-time review — run 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
# PR Improver Improve the current branch by running `/code-improver:improve` — a dynamic workflow that loops a PR reviewer and a fixer subagent over the branch's changes until a review reports zero critical/major findings. The loop, its ledger, and its guards live in the workflow; this skill derives the scope from the branch diff and relays the outcome. ## Starting the loop The user provided: `$ARGUMENTS` (if empty, take base branch and preferences from the conversation). ### 1. Resolve the branch and its change surface 1. Repo root: `git rev-parse --show-toplevel`. Fail loudly outside a repository. 2. Base: the argument if given, else the repository's default branch (`git symbolic-ref refs/remotes/origin/HEAD` → its short name, falling back to `main`). Refuse to run when the current branch IS the base — there is no diff to improve. 3. Changed files: `git diff --name-only <base>...HEAD`. If empty, say so and stop. 4. Scope: the changed files' **directories**, widened — per-file globs are too tight (PR fixes legitimately add tests next to changed code). Map each changed file to its …

How to install
mdr add trailofbits/skills/pr-improver@sha256:8bb6055905f95d4eThe 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.
