qa-only

Interactive design plan review skill that rates each UI/UX dimension on a 0-10 scale, explains what would make it a 10, and iteratively fixes the plan to reach that level — like having a CEO and engineering review for your design decisions.

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.

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.

Imports cookies from a real Chromium browser into a headless browse session through an interactive domain picker UI, enabling QA testing of authenticated pages without manual login.

Interactive developer experience plan review that explores developer personas, benchmarks against competitors, designs magical moments, and traces friction points before scoring.

A design exploration skill that generates multiple AI design variants, opens a comparison board for side-by-side review, collects structured feedback, and iterates. Useful for visual brainstorming and exploring UI design options before committing to a direction.

Land-and-deploy workflow that merges a PR, waits for CI and deploy, then verifies production health via canary checks as part of the gstack shipping pipeline.

Performs live developer experience audits by actually testing onboarding flows, navigating docs, timing TTHW (time to hello world), and screenshotting errors. Produces a DX scorecard with evidence and compares against planned targets.
