# 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 repo-relative directory glob `<dir>/**` (`**` at the repo root only if files at the root changed), then deduplicate and drop globs covered by another. ### 2. Resolve the loop script The loop is the dynamic workflow `workflows/improve.js` in this plugin. Launch it by path: `scriptPath` takes a resolved absolute path, and the Workflow tool's `name` resolves built-in and projec
