Generate, verify, cache, and link version-specific SKILL.md files for Ruby gems into ~/.gem/skills/<gem>/<version>/, the same way the gem-skill gem does but with Claude writing the skill instead of a separate LLM API call. Use when the user asks to build/generate/create a skill for a Ruby gem, build skills for every gem in a Gemfile.lock, refresh or verify gem skills, or list/purge the ~/.gem/skills cache.

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/'build-gem-skill' ] || [ -L ~/.agents/skills/'build-gem-skill' ]; then echo 'A skill folder named build-gem-skill already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadBomber/experiments' "$d" && git -C "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/build-gem-skill' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/build-gem-skill' ~/.agents/skills/'build-gem-skill' && 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/'build-gem-skill' ~/.claude/skills/'build-gem-skill' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
