97 / 100 · Low risk

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

Create, debug, and iterate on GSD extensions (TypeScript modules adding tools, commands, event hooks, custom UI, and providers). Use when asked to build an extension, add a tool the LLM can call, register a slash command, hook into GSD events, create custom TUI components, or modify GSD behavior. Triggers on "create/build extension", "add a tool", "register command", "hook into gsd", "gsd plugin".

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/'create-gsd-extension' ] || [ -L ~/.agents/skills/'create-gsd-extension' ]; then echo 'A skill folder named create-gsd-extension already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/open-gsd/gsd-pi' "$d" && git -C "$d" checkout --quiet 'c0bc9c4e7e0a8581aeac3af397031dc3a63d012e' -- 'src/resources/skills/create-gsd-extension' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/resources/skills/create-gsd-extension' ~/.agents/skills/'create-gsd-extension' && 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/'create-gsd-extension' ~/.claude/skills/'create-gsd-extension' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
