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 11d 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 — 335 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend Design Skill

Step 1: Establish Aesthetic Direction Before Writing Code

Before touching a line of CSS, decide:

  1. Purpose - What is this interface for? Who uses it? What emotion should it evoke?
  2. Tone - Serious/clinical? Playful/energetic? Minimal/confident? Bold/expressive?
  3. Differentiator - What one thing will make this memorable? (Unusual typography? Unexpected layout? Strong color contrast?)
  4. Constraint - What can you NOT use? (Overused styles to avoid)

Choose an extreme and execute with intentionality. Mediocre design lives in the middle. Either go brutally minimal or richly layered - both work; the generic middle does not.


Step 2: Typography (The Most Impactful Decision)

Font Pairing Formula

  • Display/Heading: Distinctive, character-rich (serif, slab, condensed, or geometric sans)
  • Body: Highly legible neutral (Inter, Geist, Outfit, DM Sans)

Pairings that Work

Heading Body Mood
Playfair Display Inter Editorial, premium
Space Grotesk DM Sans Tech, modern
Syne Outfit Bold, design-forward
Fraunces Source Serif Literary, warm
Cabinet Grotesk Inter Startup, clean

Font Scale (Never Use Default Browser Sizes)

:root {
  --text-xs:   0.75rem;   /* 12px - captions */
  --text-sm:   0.875rem;  /* 14px - secondary text */
  --text-base: 1rem;      /* 16px - body */
  --text-lg:   1.125rem;  /* 18px - lead text */
  --text-xl:   1.25rem;   /* 20px - small headings */
  --text-2xl:  1.5rem;    /* 24px */
  --text-3xl:  1.875rem;  /* 30px */
  --text-4xl:  2.25rem;   /* 36px */
  --text-5xl:  3rem;      /* 48px */
  --text-6xl:  clamp(3rem, 8vw, 5rem); /* Responsive hero */
}

Typography Rules

  • Heading line-height: 1.1–1.2
  • Body line-height: 1.6–1.8
  • Max line length: 65–75 characters (add max-width: 65ch to body text)
  • Never: all-caps body text, three different font weights at the same size, Arial/Times New Roman
