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

dark-blue-contrasting-clean 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 6d 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.

Dark Blue Contrasting Clean Skill

Use When

  • Create a dark-blue clean design system with strong contrast, cobalt gradient feature blocks, crisp framed structure, and restrained premium glow.

Workflow

Scope

  • Apply this as a full design-system direction across page background, framing rails, hero or CTA bands, cards, link groups, navigation, and motion.
  • Use it when the interface should feel premium, dark, crisp, and blue-led, with strong contrast between deep navy surfaces and brighter cobalt focal regions.
  • This is not an airy cloud-blue system and not loud neon sci-fi. It should stay clean, architectural, and high-contrast.

Visual target

  • Build the page on a near-black navy base, using dark blue-black backgrounds with subtle tonal variation rather than flat pure black.
  • Introduce one or more prominent cobalt or royal-blue feature blocks as contrast moments, such as hero banners, CTA bands, spotlight cards, or product sections.
  • Use white typography and pale-blue support text over the dark system so the contrast feels sharp, readable, and premium.
  • Add thin outer rails, border-x container lines, small corner squares, and quiet framing detail so the layout feels disciplined and engineered.
  • Let blue glow stay soft and localized, appearing in background blooms, button emphasis, or tiny live indicators instead of flooding the whole page.

Implementation guidance

  • Prefer a framed max-width shell or inner container with vertical boundary lines and subtle corner markers holding the composition together.
  • Use border-gradient wrappers for premium blue feature blocks and dark cards, then place cleaner inner fills inside them so the edge treatment stays crisp.
  • Organize the layout in clean stacked zones: a high-impact contrast block, then quieter index or navigation areas, followed by a restrained legal or footer zone.
  • Buttons and CTA cards should feel firm and premium, using dark translucent fills, blue-tinted borders, pale-blue copy, and hover states that brighten slightly.
  • Typography should remain light and elegant: thin to regular sans-serif weights, generous spacing, and small uppercase utility lines for section numbering or metadata.
  • Use subtle abstract blue light fields, large blurred glows, circular traces, or soft overlay washes to add atmosphere without weakening the clean structure.
  • Motion should stay calm and premium: masked word reveals, fade-up sections, quiet icon drift, and gentle hover translation are appropriate.

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.
