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

Pointer to the upstream skill for writing PRDs grounded in the existing repo, with a fixed output folder, installed from upstream.

Install

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

if [ -e ~/.agents/skills/'prd-mastery' ] || [ -L ~/.agents/skills/'prd-mastery' ]; then echo 'A skill folder named prd-mastery already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/coco-research/coco' "$d" && git -C "$d" checkout --quiet 'cd89f013b617f7eea982a9bbc60e992974fda2aa' -- 'skills/prd-mastery' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/prd-mastery' ~/.agents/skills/'prd-mastery' && 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/'prd-mastery' ~/.claude/skills/'prd-mastery' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
