Design Critic Loop
Use to raise a design to a high bar — a website, screen, UI, presentation, graphic, mockup, HTML/CSS or SwiftUI/AppKit output — via the Gauntlet Loop: independent fresh-context critics that judge against an explicit "done" bar and iterate until they pass, instead of the generator grading its own homework. Triggers: "critique this design", "run the gauntlet", "design loop", "polish this", "make it better", "raise the bar", "is this good enough". Also invoke it from another design skill after building, to verify the output against that skill's checklist. If "done" is unclear, it asks the user for goals and reference examples first. Reserve for high-value / reusable artifacts — the loop is token-expensive. NOT for routine one-off tweaks.

From the source SKILL.md
A generator can't reliably grade its own homework: it decides "looks done" and inherits its own blind spots. This skill replaces self-review with independent, fresh-context critics that judge the design against an explicit definition of done, then loops build → critique → fix until the critics stop finding real faults. Popularized as the "Gauntlet Loop" / "Design Loop" (Matt Shumer).
What this skill does
Design Critic Loop is a community-contributed Claude Code skill in the scaffolders sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/design-critic-loop/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Design Critic Loop Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 184,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Design Critic Loop skill?
Use Design Critic Loop when your Claude Code task falls under the Dev Tools category — specifically in the scaffolders area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Design Critic Loop" or describe the task and let Claude pick).

/category/tools/.
What is a Claude Code skill and how does the Design Critic Loop skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Design Critic Loop is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Dev Tools category. Learn more at
