sg-update

name	sg-update
description	Use this when GSD, Superpowers, or super-gsd may be outdated — checks each tool's installation status and installs or updates to the latest version.
argument-hint	No arguments needed.

Detect the user's input language and respond in that language throughout this skill's output. - Korean input → respond in Korean - English input → respond in English - Mixed input → match the dominant language Check whether each tool in the super-gsd workflow is installed, install it if missing, or update it if present: - GSD (@opengsd/get-shit-done-redux) — npm package - superpowers — Claude Code plugin - super-gsd — Claude Code plugin

<execution_context> Self-contained. Uses Bash to run detection and install/update commands. </execution_context>

Run the following single bash block. All steps run in one shell process so variables persist through the summary.

<success_criteria>

1. GSD npm package installed or updated to latest, with actual status shown.
2. superpowers, super-gsd plugins installed or updated (or skipped if claude not on PATH).
3. Summary shows actual installed/updated/failed/skipped state for each tool — no literal placeholder text. </success_criteria>
