Fine to try.

Use when auditing a codebase for semantic duplication - functions that do the same thing but have different names or implementations. Especially useful for LLM-generated codebases where new functions are often created rather than reusing existing ones.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'finding-duplicate-functions' ] || [ -L ~/.agents/skills/'finding-duplicate-functions' ]; then echo 'A skill folder named finding-duplicate-functions already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/boisenoise/skills-collections' "$d" && git -C "$d" checkout --quiet '419c39fde874b8baecbb36a397b967e0190a2ece' -- 'skills/superpowers-lab-finding-duplicate-functions' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/superpowers-lab-finding-duplicate-functions' ~/.agents/skills/'finding-duplicate-functions' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'finding-duplicate-functions' ~/.claude/skills/'finding-duplicate-functions' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
