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

brand-guidelines 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 2mo 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.

OneContext Brand Guidelines

Overview

OneContext is the universal AI identity platform. Our visual identity is clean, minimal, and functional—predominantly white with dark green used sparingly as a strategic accent. Prioritize infrastructure-grade reliability over consumer-app flashiness.

Keywords: OneContext brand, visual identity, UI styling, colors, typography, developer-first design, Tailwind, shadcn

Source: prompts/brand-guide-and-visual-identity.md

For tone, voice, and copy (headlines, CTAs, landing text, docs, social), use the brand-copy-guidelines skill.

Color System

Primary

  • Base: White #FFFFFF – dominant for backgrounds, forms, cards. The brand is intentionally minimal with lots of white space.
  • Primary accent: Dark Green #047857 (Tailwind emerald-700) – CTAs, links, active states, badges, key highlights. Use sparingly, not as broad fill.
  • Hover / focus: Lighter Green #10B981 (Tailwind emerald-500) – hover states, subtle highlights, focus rings.

Neutrals & Semantic

  • Neutrals: Tailwind gray scale (50–950).
  • Text (light mode): Gray-900.
  • Text (dark mode): Gray-50.
  • Dark backgrounds: Near-black #0A0A0A / #18181B.
  • Error: Red #EF4444.
  • Warning: Amber #F59E0B.

Rule: The brand is not green-heavy. Green only for interactive/important elements.

Typography

  • Primary font: Inter or Geist (open license). Use in web/app; fallback: system sans-serif.
  • Code / mono: Geist Mono, JetBrains Mono, or Fira Code for code, keys, CLIs.

Hierarchy

Element Size Weight
H1 Hero 48–64px Bold
H2 36–40px Semibold
H3 24–28px —
Body 16–18px Regular (line-height 1.6–1.7)
Small/caption 14px —

UI Component Patterns

  • Buttons: Rounded 6–8px. Primary CTA = dark green; hover/focus = lighter green. Accessible contrast.
  • Cards: White, gray border or subtle shadow, padded, clearly labeled.
  • Forms: Labels above fields, inline validation.
  • Status: Color-coded; icon + text; dark green for success/active.
  • Code blocks: Dark theme, syntax highlighting, copy button.
  • Navigation: White base; dark green underline or fill for active; mobile-responsive.
  • Spacing: 8px grid; generous whitespace.
  • Shadows: Subtle, only where elevation is needed.

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.
