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/'database-documentation' ] || [ -L ~/.agents/skills/'database-documentation' ]; then echo 'A skill folder named database-documentation already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/a-tokyo/agent-skills' "$d" && git -C "$d" checkout --quiet 'ba575306713883a7fd5cc38481d59e163e6a4a8b' -- 'skills/database-documentation' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/database-documentation' ~/.agents/skills/'database-documentation' && rm -rf "$d"; fi

For Claude Code: ln -s ~/.agents/skills/'database-documentation' ~/.claude/skills/'database-documentation' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
