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

site-specification 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Site Specification Skill

Extract detailed site specifications from user descriptions to guide theme generation. If the user has provided images, image urls or other documents, analyze them for additional clues about the brand and design preferences - obviously things like an exising logo image can be very informative about the brand's aesthetic, tone, and values, and any written documents can contain explicit statements about the brand identity or design preferences.

Site Spec Schema

A complete site specification uses this JSON structure:

{
  "siteBrief": {
    "siteName": "Name of the site/business",
    "siteType": "Type of site (e.g., e-commerce, portfolio, blog, SaaS, restaurant)",
    "primaryGoal": "Main purpose or conversion goal of the site",
    "audience": "Target audience description",
    "tone": "Voice and tone for the content",
    "brandKeywords": "Keywords describing the brand aesthetic and values"
  },
  "layoutNotes": [
    "Each layout requirement as a separate string",
    "Sections, features, and visual elements"
  ],
  "typography": {
    "primaryFont": "Main font for headings",
    "secondaryFont": "Font for body text",
    "usage": "How fonts should be applied",
    "fontImport": "Google Fonts import URL"
  }
}

All fields are optional - only include what can be reasonably inferred from the user's description.

Inference Patterns by Site Type

SaaS / Technology

Infer:

  • Primary goal: Drive signups or demo requests
  • Audience: Technical decision-makers, developers, or business users
  • Tone: Professional, innovative, trustworthy
  • Brand keywords: Modern, efficient, powerful, seamless

Typical layout:

  • Hero with value proposition and CTA
  • Feature grid or comparison
  • Social proof (logos, testimonials)
  • Pricing section
  • FAQ
  • Final CTA

Typography tendency:

  • Clean geometric sans-serifs
  • Strong hierarchy for scanning
  • Consider: Satoshi, Plus Jakarta Sans, Outfit

E-commerce / Retail

Infer:

  • Primary goal: Drive purchases
  • Audience: Consumers with specific interests
  • Tone: Varies by brand (luxury vs. casual vs. value)
  • Brand keywords: Depends on positioning

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.
