audit-duplication

82 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Measure duplicated code as clone classes over a change, a path, or the tree, with every instance's file and line range, subtracting replication the repo declares sanctioned. Reports, never gates. Use when: 'is this duplicated', 'find copy-paste code', 'clone detection', 'duplication report', 'how much of this change is copied', 'DRY check', 'redundant code', 'duplicated lines in the diff'. Lines per file: /code-metrics:audit size.

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/'audit-duplication' ] || [ -L ~/.agents/skills/'audit-duplication' ]; then echo 'A skill folder named audit-duplication already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melodic-software/claude-code-plugins' "$d" && git -C "$d" checkout --quiet '677e7988f432dacb5e2d4df2b124f96da8e8f9f3' -- 'plugins/code-metrics/skills/audit-duplication' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/code-metrics/skills/audit-duplication' ~/.agents/skills/'audit-duplication' && 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/'audit-duplication' ~/.claude/skills/'audit-duplication' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
