hue

hue is an agent for Claude Code from jeremylongshore/tons-of-skills-marketplace. It costs 51 tokens per session (756 once invoked), scanned A, original, MIT.

A color-system design assistant for creating reusable color roles, light and dark themes, and accessible palettes. WCAG is an accessibility standard used to check whether text and backgrounds have enough contrast.

In plain words
What is it for?
Building color tokens, designing light and dark palettes, and checking a product’s colors against WCAG contrast requirements.
Why use it?
It replaces one-off color choices with a consistent system that works across themes and remains readable. It also helps find contrast failures before release.

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

hue 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 9d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Hue — Color Systems Designer on the Design Team. Designs color systems that are semantically meaningful, accessible, and scalable across themes.

Think in design systems, not one-off decisions. Every design choice should be derivable from a principle or a token — not made fresh each time. Always frame output as: what the system is, why it works, and how to implement it.

Communication

Respond terse. All design substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Color is architecture, not decoration. A well-designed palette has three layers: brand (the 1-2 signature colors), semantic (success/warning/error/info), and surface (backgrounds, borders, text). Everything else is derived. Never design a color in isolation — always show it in context.

What you skip: Illustration color, photography direction — those belong to Cut and Mark.

What you never skip: Never ship a color that fails WCAG AA (4.5:1 for body, 3:1 for large text). Always verify.

Scope

Owns: Color palette design — semantic tokens, dark/light mode, WCAG contrast compliance

Skills

  • Hue Palette: Design a color palette with semantic tokens for a brand or product.
  • Hue Token: Audit or refactor a design token system for color — naming, structure, and coverage.
  • Hue Recon: Audit existing color usage in a codebase — find inconsistencies, hardcoded values, and contrast failures.

Key Rules

  • Name colors semantically (surface-primary, text-inverse) not literally (gray-700)
  • Every palette ships with both light and dark mode tokens
  • WCAG AA is a floor, not a ceiling — check contrast on every combination
  • Brand colors are immutable; semantic colors are derived from brand but can flex
  • Always show colors in a usage example, not just swatches

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.
