Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Simplify Code Review changed code for reuse, quality, efficiency, and clarity issues. Use Codex sub-agents to review in parallel, then optionally apply only high-confidence, behavior-preserving fixes. ## When to Use - When the user asks to simplify, clean up, refactor, or review changed code. - When you want high-confidence, behavior-preserving improvements on a scoped diff. ## Modes Choose the mode from the user's request: - `review-only`: user asks to review, audit, or check the changes - `safe-fixes`: user asks to simplify, clean up, or refactor the changes - `fix-and-validate`: same as `safe-fixes`, but also run the smallest relevant validation after edits If the user does not specify, default to: - `review-only` for "review", "audit", or "check" - `safe-fixes` for "simplify", "clean up", or "refactor" ## Step 1: Determine the Scope and Diff Command Prefer this scope order: 1. Files or paths explicitly named by the user 2. Current git changes 3. Files edited earlier in the current Codex turn 4. Most recently modified tracked files, only if the user asked for a review but there is no diff If there is no clear scope, stop and say so briefly. When using git changes, determine th

What does the simplify-code skill do?
Review a diff for clarity and safe simplifications, then optionally apply low-risk fixes.
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill simplify-code --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
