A visual QA skill that performs a designer's eye audit to find and fix visual inconsistencies, spacing issues, hierarchy problems, and AI slop patterns — iteratively committing each atomic fix with before/after screenshot verification.

A design consultation skill from gstack that researches your product landscape, proposes a complete design system (aesthetic, typography, color, layout, spacing, motion), and generates font and color preview pages, creating DESIGN.md as the project design source of truth.

A report-only QA testing skill that systematically tests a web application and produces a structured report with a health score, screenshots, and reproduction steps — without making any code fixes. Use it when you want a bug report without any code changes.

Wraps OpenAI Codex CLI in three modes: code review with pass/fail gating via independent diff review, challenge mode that adversarially tries to break your code, and consult mode for asking questions with session continuity.

A skill that upgrades gstack to the latest version, detecting whether it is installed globally or locally, running the upgrade, and showing a changelog of what's new. It supports auto-upgrade configuration, snooze options with escalating backoff, and restore-from-backup on failure.
