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

frontend-design 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.

Frontend Design

Overview

Create distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

Output Requirements

MANDATORY: The entry HTML file MUST be named index.html.

Design Thinking

Before coding, understand the context and commit to a BOLD aesthetic direction:

  • Purpose: What problem does this interface solve? Who uses it?
  • Tone: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc.
  • Constraints: Technical requirements (framework, performance, accessibility)
  • Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?

CRITICAL: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work — the key is intentionality.

Then implement working code (HTML/CSS/JS, React, Vue, etc.) that is:

  • Production-grade and functional
  • Visually striking and memorable
  • Cohesive with a clear aesthetic point-of-view
  • Meticulously refined in every detail

Frontend Aesthetics Guidelines

Typography

  • Choose fonts that are beautiful, unique, and interesting
  • Avoid generic fonts (Arial, Inter, Roboto, system fonts)
  • Pair a distinctive display font with a refined body font
  • Use Google Fonts or local font files

Color & Theme

  • Commit to a cohesive aesthetic
  • Use CSS variables for consistency
  • Dominant colors with sharp accents outperform timid, evenly-distributed palettes
  • Avoid cliched purple gradients on white backgrounds

Motion

  • Use animations for effects and micro-interactions
  • Prioritize CSS-only solutions for HTML
  • Focus on high-impact moments: one well-orchestrated page load with staggered reveals creates more delight than scattered micro-interactions
  • Use scroll-triggering and hover states that surprise

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.
