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-human 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (contrast-check.py, contrast-mcp.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

antislop-human

Anti Slop: Rules for AI Coding Agents. Human skill

Part of the antislop system. Read together with antislop.md (the core). This skill deep-dives the human concern: the UI must stay usable by people with different eyes, hands, and setups. Contrast, keyboard, focus, states, and the mobile details that exclude people.

How to use this skill

  • Load together with antislop.md whenever the task builds or edits UI. The core holds the mechanism (the purpose test, the three tiers, the Delivery Gate); this skill holds the human-side depth: the parts of a UI that exclude people with different eyes, hands, and setups.
  • Every entry has the same shape: Tell (the pattern), Why (who it excludes, and why it reads as unfinished), Fix (what to do instead), with the governing core rule cited as R-XX.
  • Accessibility is not a checklist of extras bolted on at the end. It is part of the core promise that "the UI holds up" (C-4). The Delivery Gate in the core remains the gate; the "Human Skill Checklist" at the end of this file is the supplement to run alongside it.
  • The contrast checker (formula + reference table + script) lives in this skill. Use it for every color pairing you cannot verify by eye.
  • This skill keeps only the mobile details that exclude people: zooming, and the on-screen keyboard.

Color & Contrast

Low-Contrast Text

  • Tell: light grey text on a white or near-white background, thin body text, muted labels chosen because they look "elegant" but are hard to read.
  • Why: it excludes low-vision users and everyone in bright light. It is a visual choice made without checking the standard, which is exactly the kind of default the filter exists to catch.
  • Fix: meet WCAG AA minimums (R-25): 4.5:1 for normal text, 3:1 for large text (18px+). Compute the ratio; do not eyeball it.

Text Over a Photo or Gradient

  • Tell: white text placed directly over an image or gradient that is light in some areas, checked at one bright spot only.
  • Why: contrast is local. Where the image is light, the text drops below 4.5:1 even if the hero still "looks" fine. R-25 requires testing the whole area the text passes over, not a single point.
  • Fix: add a scrim or a solid color block behind the text, then verify the worst spot, not the best. If any part of the text area fails, the treatment fails.

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.
