anti-slop is a set of rules and skills that coding agents use to avoid generic AI-generated interfaces, copy, and code. It is intended for people building pages or writing and reviewing text with an agent, while a user-provided DESIGN.md supplies the visual direction. The catalogue entries package these rules as agent skills and a plugin.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 8 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.14655 |
| Opus 5.5 | $0.00011 | $0.05862 |
| Sonnet 5.5 | $0.00005 | $0.02931 |
| Haiku 4.5 | $0.00003 | $0.01465 |
Grade A, and why
antislop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Anti Slop: Rules for AI Coding Agents
Follow these rules whenever generating or building UI for a website, web app, or any interface. The goal: the design should feel crafted by a designer, not generated by AI. Before applying antislop, resolve its mode using "Two Usage Modes" below. By default, ask during or after. For a saved preference or explicit session choice, instead announce
antislop active: <mode> (<source>).once, including whether the source isglobal preferenceorsession override.
First-Run Install Wizard
antislop is a system: this core file plus optional skills, one per concern (antislop-ui, antislop-copywriting, and so on, each a folder with a SKILL.md). This section installs them once. It is an offer, not a requirement: if the user prefers, this file alone remains a complete filter.
Skip this section if the project's entry file (AGENTS.md, CLAUDE.md, GEMINI.md, or the equivalent the running tool reads at session start) already contains an antislop pointer block. That means antislop is already installed. Come back only when the user asks to add or remove a skill.
If no antislop pointer exists and this file is being read for the first time, run the wizard:
The steps below are the manual install for setups where only this file is present. No network is used: missing skills are fetched by the user, never by the agent.
- Declare the setup before doing anything. Tell the user you will (a) get the chosen skill(s) in place in
skills/<name>/subfolders next to this file (the user fetches them; the agent never downloads from the network, see step 4), and (b) append an antislop pointer block at the end of the project's entry file. Get approval. Never modify the entry file silently. - Ask which skills to install (multi-select, in the user's chat language). List only the skills that exist in this version of antislop:
- 1. All (recommended): install every available skill. Choose this when the work spans UI, copy, people, or mobile layout.
- 2.
antislop-ui(UI / visual): pick this for building or editing a website, web app, or interface: color, layout, components, decoration, motion. - 3.
antislop-copywriting(copy & text): pick this for writing or editing copy: headlines, CTAs, value propositions, tone, landing-page text, product prose. - 4.
antislop-human(people): pick this for making sure a UI works for people with different eyes, hands, and setups: contrast, keyboard, focus, states. - 5.
antislop-layoutmobile(mobile / responsive): pick this for layouts that have to reflow across screen sizes, phone to desktop: breakpoints, scale, grids, overflow, tap targets. - 6.
antislop-code(code comments): pick this for writing or editing code comments: remove generic AI-slop comments, keep the valuable ones, never touch the code. - New skills appear here as they ship; never offer a skill that does not exist in this version.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

antislop is a skill published in the GitHub repository miqdadbadjuber/anti-slop (7,562 stars, last pushed 2d ago), licensed MIT. It adds 27 tokens to every session and 14,655 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
