How to use the Anti-Slop Design agent skill: install and examples
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Anti-Slop Design skill is a set of instructions that tells an AI coding agent to review frontend code (web apps, dashboards and landing pages) for common AI-generated design flaws and restyle them more restrainedly. This guide is for developers with a rough AI-made prototype and for designers or front-end engineers auditing a UI. By the end you will know how to install the skill, how to ask for it in plain language, and what to check before accepting its edits.
Anti-Slop Designsickn33/agentic-awesome-skills · MIT Download the skill Quick start
- 1Download the ZIP. Download the anti-slop-design skill ZIP from this page.
- 2Unzip the folder. Unzip the archive so you have an anti-slop-design folder containing SKILL.md.
- 3Place the skill. Move the folder to ~/.claude/skills/ for personal use, or to .claude/skills/ in a project.
- 4Or upload in the Claude apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the skill.
- 5Make a scoped request. Ask for a specific UI fix, such as cleaning up slop in one page, and name the files involved.
- 6Review the diff. Read every change the agent makes and run your app's forms and API calls to confirm behaviour is unchanged.
What is an agent skill and what does this one do?
An agent skill is a folder containing a SKILL.md file that gives an AI agent extra instructions it loads when a task matches the skill's description. This one is named anti-slop-design and is described as an autonomous principal design technologist that addresses vibe-coded software and AI frontend 'slop'.
When active, the agent works against a list of 12 flaws it looks for in UI code. Examples include purple or indigo blurred gradient blobs on dark backgrounds, raw emoji used as icons, repeated three-card grids, fabricated stats such as '+99.9% Uptime' with no source, and buttons that have only hover states. It proposes replacements such as a restrained monochrome palette, single-weight SVG icons, and full interactive state coverage.
- Replaces emoji icons with consistent vector SVG icons.
- Removes vanity metrics that have no source, or replaces them with real data.
- Adds focus-visible, active, loading and disabled states to interactive elements.
- Reduces duplicate CTAs, brand marks and filter bars on a screen.
- Keeps form state, data handlers, validation and API calls intact while restyling.
Install the anti-slop-design skill
Download the skill ZIP from this page and unzip it. For a personal install, place the resulting anti-slop-design folder in ~/.claude/skills/. For a single project, place it in that project's .claude/skills/ folder.
Alternatively, in the Claude apps, open Settings, go to Capabilities, and upload the skill under Skills.
- Personal (all projects): ~/.claude/skills/anti-slop-design/
- Single project: .claude/skills/anti-slop-design/ inside your project folder
- Claude apps: Settings → Capabilities → Skills → upload
How do you trigger the skill with a natural request?
You do not need a special command. The skill is meant to activate when your request involves building, styling, refactoring or auditing a web app, SaaS dashboard or landing page. Phrases the source lists as triggers include 'fix my UI', 'make it look professional', 'clean up AI slop', 'improve UX', 'make it look clean', 'fix the design', 'premium feel' and 'improve UI/UX'.
Naming the files or screens you want changed helps the agent scope its edits.
- 'Fix the design of this dashboard in src/components/Dashboard.tsx.'
- 'Clean up the AI slop on the landing page and keep the signup form logic unchanged.'
- 'Audit this UI for visual hierarchy and accessibility, and list the issues first.'
What should you expect the agent to change?
The skill instructs the agent to act directly on code, writing CSS variables, Tailwind classes, DOM structure and component props rather than only giving advice. It also tells the agent to delete visual clutter before adding styling. Because it may make many edits, review the diff before committing.
The skill's own guidance is that the agent should preserve interactive logic. Treat that as an instruction to the agent, not a guarantee, and test forms and API calls after the restyle.
What does the skill need and what are the safety notes?
The listing states that the skill requires nothing beyond the agent itself, runs no scripts and makes no network calls. The package contains a single file, SKILL.md.
The skill is listed under MIT licence. Because it changes code directly, use version control so you can revert, and check that your project's brand or design system is not overwritten.
- Requires: nothing listed
- Runs scripts: no
- Uses network: no
- Files: SKILL.md
Tips for better results
Give the agent the scope first. Ask for an audit before a full restyle so you can see what it intends to change.
Point it at an existing design system only if you are willing to have its aesthetic opinions applied. The skill pushes its own minimal direction and may override a specific brand.
- Commit your working code before running the skill.
- Ask for changes in one component at a time when the project is large.
- Check colours and contrast against your accessibility requirements after changes.
- Keep manual testing of forms and API calls as a final step.
What people use it for
- Turning a rough AI-generated dashboard prototype into a cleaner, more consistent interface.
- Auditing an existing UI for visual hierarchy, duplicated controls and missing button states.
- Applying a minimal, consistent design direction to a Tailwind or CSS codebase.
- Replacing emoji icons and broken placeholder image links with SVG icons and local assets.
- Reviewing a landing page for fabricated statistics and generic three-card layouts.
Frequently asked questions
Is the anti-slop-design skill free?
The skill is listed under the MIT licence, which is stated in its SKILL.md metadata and linked to the upstream LICENSE file. Check that licence file for the full terms before redistributing it.
What do I need to install the anti-slop-design skill?
The listing says it requires nothing beyond the agent environment. You need an agent that supports skills, such as the Claude apps or Claude Code, and the skill folder placed in ~/.claude/skills/ or a project's .claude/skills/ directory.
Does this skill run scripts or access the internet?
No. The listing states that it runs no scripts and uses no network. The package contains only SKILL.md.
Will it break my forms or API calls?
The skill instructs the agent to preserve form state, data handlers, validation and API integrations during restyling. Because that is an instruction rather than a guarantee, test those flows after any changes.
Can I use it with an existing brand or design system?
It is a poor fit for that. The skill pushes its own aesthetic opinions and may override a specific brand, so prefer it for prototypes or for teams that want a minimal direction.
How is it different from a general design prompt?
It is a fixed playbook with a named list of 12 AI design flaws, replacement rules and interaction-state requirements that the agent loads when the task matches, instead of you writing those rules each time.

Our verdict
Use this skill if you have a rough AI-generated frontend and want a more restrained, consistent look, or if you want a checklist-driven UI audit. Pick something else if you need to preserve an established brand system, work on backend or data code, or need a human designer to approve visual changes before they land.
