simplify skillA
simplify is agent-read markdown (skill) from alexschlessinger/polly: Clean up recently changed code without changing its behavior — parallel read-only reviewers look for missed reuse, needless complexity, wasted work, and fixes at the wrong depth, then you apply what survives. Quality only, not a bug hunt. Use when the user asks to simplify, tidy, or clean up their changes, a diff, a branch, or specific files..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Simplify
Make the changed code smaller, clearer, and cheaper while keeping what it does.
This is not a correctness review: do not go looking for bugs, and do not
"fix" behavior that looks odd but may be intended. If you trip over a real
bug, mention it in the summary and leave it alone.
## 1. Pin down the change
Work from a concrete diff, never from memory of the conversation.
- If the user named files, a commit, a range, or a branch, review exactly that.
- Otherwise, in a Git repository: take `git diff HEAD` (staged plus unstaged).
If that is empty, take the branch against its upstream
(`git diff @{upstream}...HEAD`), falling back to the default branch
(`git diff main...HEAD` or `master...HEAD`), then to `git diff HEAD~1`.
- Outside Git, ask which files to review.
Include untracked files the user clearly means (`git status --short` lists
them). If the diff is empty, say so and stop. If it is very large (thousands of
lines, dozens of files), tell the user and offer to narrow it before spending
the fan-out.
Also note any project instruction files (`AGENTS.md`, `CLAUDE.md`, and
similar at the root or in directories above changed files). Reviewers should

How to install
mdr add alexschlessinger/polly/simplify@git:20260918.5961548mdr add alexschlessinger/polly/simplify@sha256:fdef69a97ac4d80ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
