Remove the defaults. Add the taste.
Every repo from the anti-AI-slop video: what each one is for, the install command from its own README, how big and how maintained it really is, and the seven rules no tool can do for you.
This is the reference sheet from the anti-AI-slop video. Bookmark it and come back when you're setting something up.
How this was checked: star counts, licenses and last-update dates come from GitHub on September 14, 2026. Install commands come from each project's own README or skill file on the same day. Projects move fast, so if a command fails, the repo link in each section is the source of truth.

What AI slop is
Merriam-Webster named slop its 2025 Word of the Year and defines it as "digital content of low quality that is produced usually in quantity by means of artificial intelligence."
Simon Willison's framing from May 2024 is still the best test. Not all AI-generated content is slop. It's slop when it's "mindlessly generated and thrust upon someone who didn't ask for it."
Slop has three habits: it looks competent at a glance, it's cheap to make and expensive to judge, and it's easy to mass-produce.
Writing tells: delve, tapestry, "it's not X, it's Y," throat-clearing openers, em-dash spam, fake profundity, "experts agree" with no experts named.
Design tells: Inter on everything, purple-to-blue gradients, rounded cards nested in rounded cards, frosted glass, icons in little circles, and invented social proof like a testimonial from "Sarah Chen, CTO."
Taste is what you add. The tools below mostly subtract the defaults. You need both.
The recommended stack (don't install everything)
| Job | Use |
|---|---|
| Design system before code | UI/UX Pro Max |
| Always-on "don't look templated" floor | Anthropic frontend-design |
| Brand rules as a file | awesome-design-md |
| Audit and polish before you ship | Impeccable |
| Marketing pages where you want variance | Taste Skill (optional) |
| Copy, captions, READMEs | Humanizer or No AI Slop |
One generator, one finish gate and one DESIGN.md will beat five skills fighting each other.
Design
1. UI/UX Pro Max: design intelligence
Repo: nextlevelbuilder/ui-ux-pro-max-skill · ~127K★ · MIT · updated Sep 10, 2026
Before your agent writes CSS, it looks up your product type and returns a design system: style, palette, font pairing, and industry-specific rules plus anti-patterns. The README lists 192 reasoning rules, 192 color palettes and 79 searchable UI styles, ranked with BM25. Its own example is a spa that gets a calm, spa-appropriate system instead of a generic SaaS look.
npm install -g ui-ux-pro-max-cli
uipro init --ai claude # or: cursor, windsurf, copilot, and more
In Claude Code, as a plugin: /plugin install ui-ux-pro-max@ui-ux-pro-max-skill
Needs: Python 3.
2. Anthropic frontend-design: the free floor
Skill: anthropics/skills → skills/frontend-design · parent repo ~176K★ · 883.6K installs on skills.sh
It makes the model commit to a design direction specific to the brief before building. The current version also names what AI design clusters around right now, so the model can avoid those looks:
- a warm cream background with a terracotta accent (the skill notes this sits close to Anthropic's own Claude color)
- a near-black background with one acid-green or vermilion accent
- a broadsheet layout with hairline rules and zero border-radius
- the SaaS-card kit: identical rounded cards, one radius, the same soft grey shadow, gradient washes
- template chrome: ALL-CAPS eyebrow labels, meta strings joined with middle dots, a "→" appended to buttons

3. awesome-design-md: brand rules as a file
Repo: VoltAgent/awesome-design-md · ~116K★ · MIT
A collection of 73 DESIGN.md files extracted from real websites. DESIGN.md is a plain-text design system that agents read; the format was introduced by Google Stitch. Copy one into your project and tell your agent to follow it, so it builds from rules instead of vibes.
4. Impeccable: the finish gate
Repo: pbakaus/impeccable · ~68K★ · Apache 2.0 · impeccable.style
23 commands (audit, critique, polish, distill, bolder, quieter and more) plus 61 deterministic detector rules for AI-generated frontend design. The CLI and browser extension run those rules with no LLM and no API key. Use it after the generator, before you publish.
npx impeccable install
Then run /impeccable init inside your agent, once per product.
5. Taste Skill: anti-slop with dials (optional)
Repo: Leonxlnx/taste-skill · ~87K★ · MIT
Three 1–10 dials at the top of the skill: DESIGN_VARIANCE, MOTION_INTENSITY and a density dial. The default skill (design-taste-frontend) is v2 and marked experimental. It's best for landing pages and portfolios. It can go loud fast, so pair it with a DESIGN.md.

|---|---|---|
| Nutlope/hallmark | ~28.6K | Design skill from Together AI: 21 themes and 57 slop-test gates |
| github/awesome-copilot → anti-ui-slop | repo ~39K | Copilot skill by UIZZE: grounds UI in 800,000+ real screens, with a finish gate |

Writing
| Repo | Stars | Notes |
|---|---|---|
| blader/humanizer | ~47.8K | The best-known writing skill. Built on Wikipedia's Signs of AI writing. Read what it changes. npx skills add blader/humanizer --global |
| petergyang/no-ai-slop | ~9.3K | Voice-preserving; edit mode or "is this slop?" detect mode. npx skills add petergyang/no-ai-slop --skill no-ai-slop --global --yes |
| conorbronsdon/avoid-ai-writing | ~4.4K | Top pick for English prose in the upkeep survey below (A+). Detect-only and edit modes |
| hardikpandya/stop-slop | ~17.1K | Early breakout, no updates since March 17, 2026; graded F for upkeep. Use it as a frozen checklist |
| shannhk/avoid-slop | 183 | Directory of anti-slop tools for writing, code and design |
Stars aren't upkeep. ai-writing-skill-field-guide measured 68 humanizer skills on July 30, 2026 and ranked them by maintenance. Its finding: "Stars and maintenance are uncorrelated."
Detectors (they flag, they don't rewrite)
These are mostly small, early projects. Treat them as experiments.
| Repo | Stars | What it does |
|---|---|---|
| distil-labs/distil-ai-slop-detector | 94 | A 270M-parameter model that runs in your browser |
| MauroPello/stop-the-slop | 7 | Chrome/Firefox extension that flags AI-generated YouTube scripts |
| bradleydwyer/sloppy | 1 | Regex CLI, no LLM, runs in under 30ms |
| awnist/slop-cop | 161 | Browser editor that highlights LLM prose tells (uses Claude passes) |
| SamBroomy/is-it-slop | 14 | Small ML classifier |
| ai158z/slop-block | 0 | Chrome extension that highlights and blocks slop in your X feed |
| peakoss/anti-slop | 825 | GitHub Action that detects and closes low-quality, AI slop pull requests (AGPL-3.0) |
Paid "undetectable" humanizers are built to beat detectors. That's a different goal from sounding like a person with taste.
Seven rules no tool does for you
- Start from your notes, your voice, or something you actually did, never from "write a post about X."
- Put in one detail only you could write.
- Take a position. Models default to safe and hedged.
- Cut the fingerprints listed above.
- Read it out loud, and check the UI at full zoom.
- Fact-check before you polish.
- Keep the last pass human.
The four-step install
# 1. Design system
npm install -g ui-ux-pro-max-cli
uipro init --ai claude
# 2. Generation floor
npx skills add https://github.com/anthropics/skills --skill frontend-design
# 3. Finish gate
npx impeccable install
# 4. Words
npx skills add petergyang/no-ai-slop --skill no-ai-slop --global --yes
# or: npx skills add blader/humanizer --global
Then add a DESIGN.md (yours, or one from awesome-design-md). Skip Taste Skill unless it's a marketing page and you want variance.
Pro Max for the system, frontend-design for the floor, Impeccable for the audit, Humanizer or No AI Slop for the words.
