Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00526 |
| Opus 5 | $0.00016 | $0.00263 |
| Sonnet 5 | $0.00006 | $0.00105 |
| Haiku 4.5 | $0.00003 | $0.00053 |
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
Output Format
| Category | Issues | Status |
|---|---|---|
| Color system | X | ✅/❌ |
| Contrast | X | ✅/❌ |
| Typography | X | ✅/❌ |
| Spacing | X | ✅/❌ |
| Iconography | X | ✅/❌ |
| Visual states | X | ✅/❌ |
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.

visual-design-and-contrast is a skill published in the GitHub repository mwd1234/ios-agentic-skills (50 stars, last pushed 7mo ago), licensed MIT. It adds 32 tokens to every session and 526 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-30.
