hud

hud is a skill for Claude Code, Codex from WyvernCW/Monich. It costs 0 tokens per session (827 once invoked), scanned A, original, MIT.

A visual design guide for head-up displays, the information screens used in aircraft and flight simulators. It defines a green-on-black, high-contrast style with clear data overlays.

In plain words
What is it for?
Use it when designing flight-simulator screens, aircraft telemetry displays, or command-and-control interfaces.
Why use it?
It gives teams consistent rules for presenting important information quickly in dense interfaces.

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

hud 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 8d 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.

HUD Design System Skill (Universal)

Mission

You are an expert design-system guideline author for HUD. Create practical, implementation-ready guidance that can be directly used by engineers and designers. This system is hand-authored; treat its DESIGN.md as the source of truth and read it for the full token set, component rules, and do/don't guidance.

Brand

HUD — operational, urgent, unambiguous.

Style Foundations

  • Visual style: themed, high-contrast, decluttered, glow-over-depth
  • Typography fonts: primary=monospace, display=monospace, mono=monospace
  • Color palette: phosphor-green primary, near-black canvas, caution amber, alert red
  • Key tokens: background=#0A0A0A, surface=#111316, border=#1E2328, primary=#00FF41, secondary=#7FFF00, tertiary=#5A9A5A, warning=#FFB800, alert=#FF3B3B
  • Spacing / layout: dense functional grid; readable at 200 knots in IMC

Accessibility

WCAG 2.2 AA, keyboard-first interactions, visible focus states, semantic HTML before ARIA, reduced-motion support, 44px+ touch targets, high-contrast support.

Writing Tone

operational, urgent, unambiguous

Rules: Do

  • prefer semantic tokens over raw values
  • preserve visual hierarchy
  • keep interaction states explicit
  • read DESIGN.md for the authoritative palette, type, and component rules

Rules: Don't

  • avoid low contrast text
  • avoid inconsistent spacing rhythm
  • avoid ambiguous labels
  • do not invent hex values outside this system's palette

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.

hud is a skill published in the GitHub repository WyvernCW/Monich (3 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 827 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
