About the project

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.

Token cost

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.

Security

Grade A, and why

antislop-ui 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 12d ago.

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. UI & Visual skill

Part of the antislop system. Read together with antislop.md (the core). This skill deep-dives the UI/visual concern: color, layout, components, decoration, structural flow, and motion. It references core rules by number and never duplicates or renumbers them. Load it when the task builds or edits a website, web app, or any interface.

How to use this skill

  • Load together with antislop.md whenever the task is UI or visual work. The core holds the mechanism (the purpose test, the three tiers, the Delivery Gate); this skill holds UI-specific depth.
  • Every entry has the same shape: Tell (the pattern), Why (why it reads as slop), Fix (what to do instead), with the governing core rule cited as R-XX.
  • The Delivery Gate in the core remains the gate. The "UI Skill Checklist" at the end of this file is the UI-specific supplement to run alongside it.

Visual & Color

Generic Blue-Purple Gradient

  • Tell: blue-to-purple, blue-to-cyan, or purple-to-pink gradients used as the primary color treatment, or a full-page colored glow.
  • Why: the most over-represented color treatment in training data. It signals "no brand identity", not "our palette", and marks the design as AI-generated at a glance.
  • Fix: pull the palette from DESIGN.md or the product's own identity. Keep a gradient only as a hierarchy function with the reason written down (R-01). A gradient separating one level from another is craft; the same gradient on every section is a default.
  • The same default family: harsh or rainbow gradients, purple-and-black schemes, neon or pastel palettes, and blurred radial orbs behind the hero. They are the same tell wearing different clothes: color from the model's default, not from the brand. All of them are FORBIDDEN as defaults without purpose (R-01).

Excessive Glassmorphism

  • Tell: blur/backdrop-filter on the navbar, cards, modals, and sidebar at the same time.
  • Why: blur removes texture and sits every surface in the same frosted layer, flattening hierarchy. When every surface is glass, nothing is foreground.
  • Fix: treat glass as an accent, not a character trait. Dose cap: at most 1-2 elements (R-10). The surface that needs the attention gets the glass; everything else stays solid.

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.
