cleanup-legacy

80 / 100 · Low risk

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

By roohe/agentic-super-skills (GitHub) · coding · 10 stars · scanned at commit f483e54

Find and remove deprecated, legacy, and fallback code paths with zero callers. Verifies callers via repo grep + LSP before deletion. Removes unreachable fallback branches. Use when the user asks to remove deprecated code, clean up legacy paths, drop fallbacks, or simplify code branches. Example queries — "remove the deprecated API", "drop the v1 fallback", "this code is marked legacy, kill it", "simplify these branches".

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'cleanup-legacy' ] || [ -L ~/.agents/skills/'cleanup-legacy' ]; then echo 'A skill folder named cleanup-legacy already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/roohe/agentic-super-skills' "$d" && git -C "$d" checkout --quiet 'f483e54f3ad5f202a77d45f2e57f8d970b71195f' -- 'skills_library/cleanup-legacy' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills_library/cleanup-legacy' ~/.agents/skills/'cleanup-legacy' && 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/'cleanup-legacy' ~/.claude/skills/'cleanup-legacy' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
