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 | $0.00042 | $0.03188 |
| Opus 5 | $0.00021 | $0.01594 |
| Sonnet 5 | $0.00008 | $0.00638 |
| Haiku 4.5 | $0.00004 | $0.00319 |
Grade A, and why
axiom-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 9d 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.

When to Use This Skill
Use when:
- Making visual design decisions (colors, backgrounds, typography)
- Reviewing UI for HIG compliance
- Answering "Should I use a dark background?"
- Choosing between design options
- Defending design decisions to stakeholders
- Quick lookups for common design questions

Version-Conditional Design
When supporting both iOS 25 (pre-Liquid Glass) and iOS 26+, see axiom-liquid-glass for the adoption strategy — it covers when to use #available(iOS 26, *), how to degrade gracefully, and which system components adopt Liquid Glass automatically vs which need explicit opt-in.
Quick Decision Trees
Background Color Decision
Is your app media-focused (photos, videos, music)?
├─ Yes → Consider permanent dark appearance
│ WHY: "Lets UI recede, helps people focus on media" (Apple HIG)
│ EXAMPLES: Apple Music, Photos, Clock apps use dark
│ CODE: .preferredColorScheme(.dark) on root view
│
└─ No → Use system backgrounds (respect user preference)
CODE: systemBackground (adapts to light/dark automatically)
GROUPED: systemGroupedBackground for iOS Settings-style lists
Apple's guidance: "In rare cases, consider using only a dark appearance in the interface. For example, it can make sense for an app that enables immersive media viewing to use a permanently dark appearance."
Color Selection Decision
Do you need a specific color value?
├─ No → Use semantic colors
│ label, secondaryLabel, tertiaryLabel, quaternaryLabel
│ systemBackground, secondarySystemBackground, tertiarySystemBackground
│ WHY: Automatically adapts to light/dark/high contrast
│
└─ Yes → Create Color Set in asset catalog
1. Open Assets.xcassets
2. Add Color Set
3. Configure variants:
├─ Light mode color
├─ Dark mode color
└─ High contrast (optional but recommended)
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.

axiom-hig is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 3,188 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 2026-09-03.
