Refactor changed code to reduce duplication, complexity, and wasted work. Use for diffs, commit ranges, PRs, paths, staged changes, or working-tree changes.
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
# Simplify
`at-simplify → 4 cleanup agents in parallel → apply the fixes`
You are improving the quality of the changed code, not hunting for bugs. Review
it for reuse, simplification, efficiency, and altitude issues, then fix what you
find. Do not look for correctness bugs — that is what `at-review` is for.
## Phase 0 — Gather the diff
Run `git diff "@{upstream}...HEAD"` (or `git diff main...HEAD` / `git diff HEAD~1`
if there's no upstream) to get the unified diff under review. If there are
uncommitted changes, or the range diff is empty, also run `git diff HEAD` and
include the working-tree changes in scope — the review often runs before the
commit. If a PR number, branch name, or file path was passed as an argument,
review that target instead. Treat this diff as the review scope.
## Phase 1 — Review (4 cleanup agents in parallel)
Launch **4 independent review agents** using multi-agent capabilities, all in a
single message so they run concurrently. Pass each agent the diff and one of
the four angles below. Each returns its findings with `file`, `line`, a
one-line `summary`, and the concrete cost (what is duplicated, wasted, or
harder to maintain).

How to install
mdr add kairyou/agent-tools/at-simplify@sha256:1fa0426e12991cc1The line at the top of this page pins the label git:20260907.ccdf6f4, 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.
