visual-design-and-contrast is a skill for Claude Code, Codex from mwd1234/ios-agentic-skills. It costs 32 tokens per session (526 once invoked), scanned A, original, MIT.

A visual review checklist for SwiftUI app screens based on Apple’s Human Interface Guidelines, the design rules for Apple platforms. It checks colors, contrast, text, spacing, icons, and visual accessibility.

In plain words
What is it for?
Use it to review SwiftUI screens before App Store submission, after theme or layout changes, or when users report readability problems. It covers semantic colors, contrast ratios, typography, spacing, icons, and accessibility visuals.
Why use it?
It helps find inconsistent or hard-to-read interface choices before release or after a major redesign. It also checks whether light and dark modes and color-based status cues work for users with different visual needs.

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

visual-design-and-contrast 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 11d 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.

What it actually says

Visual Design & Contrast (HIG-First)

Audit visual consistency and accessibility against Apple’s Human Interface Guidelines (HIG).

When to use this skill

  • Before App Store submission
  • After large UI updates or new themes
  • When introducing new colors or typography
  • When users report readability issues

Required Guidance

Always use Apple’s Human Interface Guidelines (HIG) as the source of truth for design decisions. For documentation lookup, use the sosumi.ai MCP server. The sosumi.ai site has an “MCP Usage” section that explains how to connect the MCP server in your IDE/Claude Code/etc.


Step 1: Color System Audit

  • Use semantic colors (not hard-coded RGB)
  • Ensure Dark Mode parity
  • Avoid color-only status indicators

Checks:

  • All custom colors defined in asset catalogs
  • No hard-coded Color(.sRGB, …) in views

Step 2: Contrast & Readability

Manual checks:

  • Accessibility Inspector contrast checks
  • 4.5:1 contrast for body text, 3:1 for large text

Avoid:

  • Light text on bright backgrounds
  • Thin fonts at small sizes

Step 3: Typography Consistency

  • Prefer semantic fonts: .body, .headline, .title2
  • Respect Dynamic Type
  • Avoid fixed font sizes unless absolutely necessary

Step 4: Spacing & Layout Rhythm

  • Use consistent spacing tokens (8/12/16/24)
  • Avoid arbitrary per-view padding
  • Use alignment guides consistently

Step 5: Iconography & SF Symbols

  • Use SF Symbols where possible
  • Avoid mixing styles (outline vs filled) in same context
  • Ensure icon meaning is obvious without color

Step 6: Visual States

  • Distinct states for normal/selected/disabled
  • Clear focus ring / selection treatment
  • Hover / pressed feedback where applicable

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.
