# Codex Simplify Run a post-implementation cleanup pass over recently changed files. This skill is the Codex approximation of Claude Code's bundled `/simplify` behavior. It intentionally lives outside `.claude/skills/` and uses the non-conflicting name `codex-simplify` so Claude Code keeps its native `/simplify` command. Preserve the public contract: - target recently changed files - review for reuse, quality, and efficiency - use three independent review passes - aggregate findings - apply fixes Treat any user-supplied focus, such as memory efficiency, dead code, duplication, or readability, as extra weighting rather than a replacement for the core three review lenses. ## When to use Use this skill when: - the code already exists - the implementation or bug fix is already done - the user wants a cleanup or refactoring pass rather than new feature work - a workflow calls for a `/simplify`-style pass after review approval Do not use this skill as a substitute for initial implementation, plan compliance review, or full validation. ## Target file selection Approximate "recently changed files" with this priority order: 1. Tracked unstaged changes in the current worktree 2. Tracked staged changes 3. Untracked files clearly related to the current task 4. If the tree is clean, files changed by the most recent commit Use git to discover the set. Prefer file lists equivalent to: ```bash git diff --name-only --diff-filter=ACMR git diff --cached --name-only --diff-filter
