What Simplify does

Simplify reviews changed code for duplication, complexity, efficiency, and architecture fit, then applies cleanup fixes. Use it on diffs, commit ranges, PRs, paths, staged changes, or working-tree changes.

Simplify is cataloged under Quality on DirSkills. Simplify comes from a repository tagged agent-hooks, agent-skills, claude-code, codex and coding-agents.

Documentation

README

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.

This is the opening of the README. Read the full README on GitHub.
