</div>antislop is a rulebook an AI coding agent reads every session. It stops generic UI, text, and AI-shaped code, and it is a filter, not a style guide: no colors, fonts, or layouts prescribed, direction stays yours. Inside are 40 rules in three tiers, a Liveliness Toolkit, a mandatory PASS/FAIL report, and six skills that load only when a task needs them. It cannot invent direction, so DESIGN.md supplies that, and antislop never beautifies on its own.
Before and after
Each pair below is one brief, run twice, so the difference is visible side by side.
UI
With /antislop-ui. antislop alone is not the after. It removes the slop and stops there; direction comes from DESIGN.md. For UI work you intend to ship, that file is mandatory: without it the result is labelled a draft without direction. The pair below is the result.
| Before: without antislop | After: antislop + DESIGN.md |
|---|---|
| <a href="assets/compare/ui/without.webp"><img src="assets/compare/ui/without.webp" alt="The before: a generic landing page with a sparkle logo, a NEXT-GEN AI 2.0 beta pill above the headline, and a fake terminal reporting 0.0001ms latency" width="100%"></a> | <a href="assets/compare/ui/w-all.webp"><img src="assets/compare/ui/w-all.webp" alt="The after: the same page with antislop and DESIGN.md, a full-bleed illustrated hero with one honest headline and project-specific navigation" width="100%"></a> |
| This is what most AI output looks like: slop everywhere once you take a closer look. | Much better. antislop kills the slop, and DESIGN.md gives it a real visual direction. |
The two partial states are worth seeing, because each one shows why the other half matters:
| Partial: antislop alone | Partial: DESIGN.md alone |
|---|---|
| <a href="assets/compare/ui/w-antislop.webp"><img src="assets/compare/ui/w-antislop.webp" alt="Partial result: antislop with no design direction, a plain dark layout with the invented numbers removed" width="100%"></a> | <a href="assets/compare/ui/w-design.webp"><img src="assets/compare/ui/w-design.webp" alt="Partial result: DESIGN.md with no filter, a photographic hero with stat cards still reading 10,000% ROI Synergy Multiplier" width="100%"></a> |
The slop is gone, but so is the direction. That is why antislop needs a DESIGN.md. | The direction is there, but honestly it is still far from good: the slop still shows. |
Copywriting
With /antislop-copywriting. One prompt, run twice.
<a href="assets/compare/copywriting/before-after.png"><img src="assets/compare/copywriting/before-after.png" alt="Side by side: before, an AI written Discord launch post with NEW DROP in capitals, emoji bullets, and hype in every line; after, the same post in plain sentences, with a note to cut any line that has nothing real to say" width="100%"></a>
Accessibility
With /antislop-human. One sign-in form, run twice.
<a href="assets/compare/human/before-after.png"><img src="assets/compare/human/before-after.png" alt="Side by side: before, a sign-in form with pale grey labels, a radio button, and blue body links; after, the same form with darker labels, a checkbox, underlined links, and a solid black button" width="100%"></a>
Mobile layout
With /antislop-layoutmobile. One dashboard on a phone, run twice.
<a href="assets/compare/layoutmobile/before-after.png"><img src="assets/compare/layoutmobile/before-after.png" alt="Side by side: before, a desktop finance dashboard squeezed onto a phone with a clipped headline and a wide table; after, the same screen with a donut chart, stacked allocation bars, and one readable column" width="100%"></a>
Code
With /antislop-code. One file, run twice.
<a href="assets/compare/code/before-after.png"><img src="assets/compare/code/before-after.png" alt="Side by side: before, Python with box-drawing section banners, emoji, and a comment restating every constant; after, the same code with the banners and emoji gone and one comment left where it says something" width="100%"></a>
Every image here opens full size if you click it.
Install
antislop ships as standard agent skills: one folder per skill, holding a SKILL.md. Installation differs per agent, so pick the section for the one you use. Each route is walked through from zero, with update and removal, in GUIDE.md.
The installer (recommended)
One command, then answer the prompts. It asks which skills you want, where to install them (this project or everywhere), and which agents you use, then copies the folders and writes the pointer that reloads antislop every session.
npx antislop-ai
The skills directory
antislop is listed on skills.sh, the open directory for agent skills. This copies the same folders as the installer and nothing else, so antislop reloads by description alone.
npx skills add miqdadbadjuber/anti-slop
Claude Code - Plugin
/plugin marketplace add https://github.com/miqdadbadjuber/anti-slop
/plugin install antislop@anti-slop
Antigravity - Plugin
agy plugin install https://github.com/miqdadbadjuber/anti-slop
Codex - Plugin
codex plugin marketplace add miqdadbadjuber/anti-slop
codex plugin add antislop@anti-slop
Cursor - Plugin
agent plugin marketplace add https://github.com/miqdadbadjuber/anti-slop
Then open Customize, find antislop, and select Install.
Kimi Code - Plugin
/plugins install https://github.com/miqdadbadjuber/anti-slop
DeepSeek Harness - Plugin
Open Plugins, choose Add plugin, paste this package name, and select Install:
antislop-ai
That is the desktop route. From a terminal instead, name the profile you use:
dsh plugin --profile desktop add antislop-ai
Cline - Plugin
cline plugin install https://github.com/miqdadbadjuber/anti-slop.git
This door covers the Cline CLI. For the VS Code or JetBrains extension, use the installer.
Muse Code - Plugin
Muse Code keeps its plugin system behind an opt-in flag, so set it first. On macOS and Linux:
export MUSE_EXPERIMENTAL_PLUGINS=1
muse plugins marketplace add anti-slop miqdadbadjuber/anti-slop
muse plugins install antislop@anti-slop
On Windows, set $env:MUSE_EXPERIMENTAL_PLUGINS = "1" in PowerShell first, then run the two muse lines unchanged.
Skills load without another step. Run muse plugins approve antislop to enable the contrast MCP server.
Oh My Pi - Plugin
omp plugin marketplace add miqdadbadjuber/anti-slop
omp plugin install antislop@anti-slop
Pi - Package
pi install git:github.com/miqdadbadjuber/anti-slop
The single file
antislop.md on its own is a complete filter you can paste into any chat window, with no packaging and no folders.
curl -o antislop.md https://raw.githubusercontent.com/miqdadbadjuber/anti-slop/main/antislop.md
Skills
| Skill | Covers | Pick it for |
|---|---|---|
| antislop | The core filter: rules, tiers, the Delivery Gate, liveliness | Everything. Always loaded |
| antislop-ui | Layout, color, components, decoration, motion, structure, performance | UI and visual work |
| antislop-copywriting | Headlines, CTAs, tone, fake stats, anti-AI writing, markdown hygiene | Copy and text |
| antislop-human | Contrast, keyboard, focus, states, interaction affordances | Accessibility |
| antislop-layoutmobile | Reflow across screen widths, breakpoints, grids, overflow, tap targets | Responsive work |
| antislop-code | AI-slop comments: which to remove, which to keep | Comment cleanup |
Install one, several, or the core alone.
Usage modes
antislop runs one of two ways, and by default the agent asks which at the start of every session.
- During guides the work while it is built, and closes with the Delivery Gate report.
- After audits work that already exists: a numbered findings list, you approve what to fix, then a follow-up report.
To skip the question, save a preference once:
npx antislop-ai --mode during
Use after for the other mode. Everything else, from --mode ask to where the setting lives, is in GUIDE.md.
Update
antislop does not update itself. If you installed through the installer, one command replaces what is already there, in this project and under your home directory, and prints the release it replaced:
npx antislop-ai --update
A plugin keeps its own copy under the agent that installed it, so it updates through its own command, and the Pi package updates through Pi. Every route is listed in GUIDE.md. Skills load when a session starts, so start a new one afterwards.
FAQ
Is antislop a style guide? No, a filter. It rejects technique without purpose and requires liveliness. Direction is yours.
Which agents does it work with? Claude Code, Codex, Antigravity, OpenCode, Cursor, Cline, Amp, Gemini CLI, Hermes, GitHub Copilot, Kimi Code, DeepSeek Harness, Muse Code, Kilo Code, Pi, and Oh My Pi. The installer covers fifteen of them and detects which ones you have, and the plugin doors install from this same repository. GUIDE.md lists the folder each agent reads.
What is a skill?
A folder that goes deeper into one concern, holding a SKILL.md with its rules. Skills reference the core rules by number and never duplicate them, so adding one does not change the core.
Roadmap
v3.2.30 adds Kilo Code to the installer:
- Shared folder. Kilo Code reads
.agents/skillsat both scopes, the folder Antigravity, Copilot, Kimi Code, Amp, DeepSeek Harness, and Muse Code already share. - A folder of its own. Kilo Code also documents
.kilo/skills/, but the shared folder is loaded by default, so the installer writes one copy.
Every earlier release, and what comes next, is in ROADMAP.md.

Get antislop from miqdadbadjuber/anti-slop, antislop.ai.id, or the antislop-ai npm package. The npm name antislop belongs to a different package, so npx antislop does not install this project.
