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

Builds a branch graveyard for a git repository. Reads every local and remote branch, records who last touched it and when, computes age, ahead/behind, and whether it is merged into the trunk, then renders a light-theme website that shows the stale branches as headstones and lists the ones that are safe to delete. Use when the user runs /branch-tombs or asks about stale, dead, abandoned, or old branches, branch cleanup, or which branches are safe to prune.

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/'branch-tombs' ] || [ -L ~/.agents/skills/'branch-tombs' ]; then echo 'A skill folder named branch-tombs already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/diegopacheco/ai-playground' "$d" && git -C "$d" checkout --quiet 'd9a66a7614b743615074ea74689ae2039fadcb2d' -- 'pocs/agent-skill-branch-tombs' && mkdir -p ~/.agents/skills && cp -R "$d"/'pocs/agent-skill-branch-tombs' ~/.agents/skills/'branch-tombs' && 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/'branch-tombs' ~/.claude/skills/'branch-tombs' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
