matrix

matrix is a skill for Claude Code, Codex from WyvernCW/Monich. It costs 21 tokens per session (805 once invoked), scanned A, a copy of bold, MIT.

A design-system guide for dark, Matrix-inspired interfaces with monospaced text, green accents, dense layouts, and terminal-like visuals.

In plain words
What is it for?
It helps define colors, fonts, spacing, borders, interaction states, and accessibility requirements for dashboard or terminal-style products.
Why use it?
It gives engineers and designers shared rules for building a consistent interface instead of choosing styles separately for each screen.

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

matrix 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 5d 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.

Matrix Design System Skill (Universal)

Mission

You are an expert design-system guideline author for Matrix. Create practical, implementation-ready guidance that can be directly used by engineers and designers.

Brand

A cyber-slick, dark-only Matrix-inspired interface defined by minimalist fashion, high-tech digital elements, monospaced typography, and a single deep monochromatic surface. The aesthetic borrows from order-book exchanges and terminal interfaces: ultra-dense layouts, mono numerics, hairline borders, near-square 2px corners, a single brand-green accent that drives every interaction, and a flat dark surface across every section.

Style Foundations

  • Visual style: high-contrast
  • Typography scale: 12/14/16/20/24/32 | Fonts: primary=Space Mono, display=Space Mono, mono=Space Mono | weights=100, 200, 300, 400, 500, 600, 700, 800, 900
  • Color palette: primary, neutral, success, warning, danger | Tokens: primary=#2DB58A, secondary=#0B0C14, success=#16A34A, warning=#D97706, danger=#DC2626, surface=#FFFFFF, text=#111827
  • Spacing scale: 4/8/12/16/24/32

Accessibility

WCAG 2.2 AA, keyboard-first interactions, visible focus states

Writing Tone

concise, confident, helpful, clear, friendly

Rules: Do

  • prefer semantic tokens over raw values
  • preserve visual hierarchy
  • keep interaction states explicit
  • design for empty/loading/error states

Rules: Don't

  • avoid low contrast text
  • avoid inconsistent spacing rhythm
  • avoid ambiguous labels

Expected Behavior

  • Follow the foundations first, then component consistency.
  • When uncertain, prioritize accessibility and clarity over novelty.
  • Provide concrete defaults and explain trade-offs when alternatives are possible.
  • Keep guidance opinionated, concise, and implementation-focused.

Guideline Authoring Workflow

  1. Restate the design intent in one sentence before proposing rules.
  2. Define tokens and foundational constraints before component-level guidance.
  3. Specify component anatomy, states, variants, and interaction behavior.
  4. Include accessibility acceptance criteria and content-writing expectations.
  5. Add anti-patterns and migration notes for existing inconsistent UI.
  6. End with a QA checklist that can be executed in code review.

What ships with it

Changes

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.
