hig

hig is a skill for Claude Code, Codex from roedyrustam/vibes-plug. It costs 74 tokens per session (2,366 once invoked), scanned A, original, MIT.

A guide to applying Human Interface Guidelines to web and mobile interfaces. These guidelines describe common principles for clear hierarchy, consistent layouts, familiar controls, and accessible interaction.

In plain words
What is it for?
Use it to review UI designs, choose typography and colour treatments, improve navigation and layout, and keep experiences consistent across iOS, Android, web, and spatial interfaces.
Why use it?
It helps identify confusing or inconsistent interface decisions and align designs with platform conventions.

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

hig 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 2d 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.

Human Interface Guidelines (HIG) Expert (2026 Edition)

English | Bahasa Indonesia


English

Orchestration & Integration

Connects and orchestrates with relevant domain skills like brainstorming, zero-to-prod-orchestrator, and project-context-mapper to ensure cohesive execution.

Description

Applies Human Interface Guidelines (HIG) principles to web and mobile UI/UX designs. Covers the core triad (Hierarchy, Harmony, Consistency), Apple's HIG 2025 updates, Google Material Design 3, spatial design for Apple Vision Pro, and modern accessibility requirements.

Trigger Conditions

  • Reviewing or critiquing a UI design for HIG violations.
  • Making design decisions about typography scale, color usage, or layout hierarchy.
  • Designing for multiple platforms (iOS, Android, web) with consistent patterns.
  • Evaluating whether a UI feels "premium" or "amateur".
  • Ensuring UI components follow platform conventions (button placement, nav patterns).

The Core HIG Triad

1. Hierarchy — Guide the User's Eye

Visual hierarchy controls where the user looks first and how they navigate information.

Typography Hierarchy:

/* Clear hierarchy with size and weight — 4 levels max */
.h1 { font-size: 2.25rem; font-weight: 700; letter-spacing: -0.02em; }
.h2 { font-size: 1.5rem;  font-weight: 600; letter-spacing: -0.01em; }
.h3 { font-size: 1.25rem; font-weight: 600; }
.body { font-size: 1rem;    font-weight: 400; }
.caption { font-size: 0.875rem; font-weight: 400; color: var(--color-text-muted); }

Spatial Hierarchy (Z-axis):

  • Surface level: cards, panels — shadow-sm
  • Raised level: dropdowns, tooltips — shadow-md
  • Overlay level: modals, drawers — shadow-xl
  • Floating level: toasts, command palette — shadow-2xl

Color Hierarchy:

  • Primary action: brand color (1 per screen)
  • Secondary action: muted/ghost variant
  • Destructive action: red — far from primary CTA
2. Harmony — Visual Cohesion

All elements should feel like they belong to the same family.

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.
