mono

mono is a skill for Claude Code, Codex from WyvernCW/Monich. It costs 26 tokens per session (785 once invoked), scanned A, a copy of bold, MIT.

A design guide for compact, monospace interfaces with matrix-inspired colors, strong contrast, and a hacker-themed visual style.

In plain words
What is it for?
Use it to set typography, colors, spacing, hierarchy, interaction states, responsive behavior, and accessible labels.
Why use it?
It gives a consistent structure to dense technical interfaces that might otherwise become difficult to scan or use.

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

mono 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 7d 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.

Origin

77% identical to bold — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Style Foundations

  • Visual style: minimal, clean, high-contrast, playful, matrix
  • Typography scale: desktop-first expressive scale | Fonts: primary=Space Mono, display=Space Mono, mono=JetBrains Mono | weights=100, 200, 300, 400, 500, 600, 700, 800, 900
  • Color palette: primary, secondary, success, warning, danger, info | Tokens: primary=#37F712, secondary=#00A6F4, success=#00A63D, warning=#FE9900, danger=#FF2157, surface=#E7E5E4, text=#78716B
  • Spacing scale: compact density mode

Accessibility

WCAG 2.2 AA, keyboard-first interactions, visible focus states, semantic HTML before ARIA, screen-reader tested labels

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
  • ensure responsive behavior by default

Rules: Don't

  • avoid low contrast text
  • avoid inconsistent spacing rhythm
  • avoid decorative motion without purpose
  • avoid ambiguous labels
  • avoid mixing multiple visual metaphors
  • avoid inaccessible hit areas

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 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.
