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 | $0.00178 | $0.01167 |
| Opus 5 | $0.00089 | $0.00583 |
| Sonnet 5 | $0.00036 | $0.00233 |
| Haiku 4.5 | $0.00018 | $0.00117 |
Grade A, and why
hig-components-content 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 5d 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.
This is a copy
100% identical to hig-components-content — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apple HIG: Content Components
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
-
Adapt to different sizes and contexts. Content components must work across screen sizes, orientations, and multitasking configurations. Use Auto Layout and size classes.
-
Make content accessible. Charts need audio graph support. Images need alt text. Collections need proper VoiceOver navigation order. All content components need labels and descriptions.
-
Maintain visual hierarchy. Use spacing, sizing, and grouping to establish clear information hierarchy. Primary content should be visually prominent.
-
Use system components first. Evaluate UICollectionView, SwiftUI Charts, WKWebView before building custom. System components come with built-in accessibility and platform adaptation.
-
Respect platform conventions. A collection on tvOS uses large lockups with parallax. The same collection on iOS uses compact cells with touch targets. On visionOS, content gains depth and hover effects.
-
Handle empty states. Show a meaningful empty state with guidance on how to populate it, not a blank screen.
-
Optimize for performance. Use lazy loading, cell reuse, pagination, and prefetching for large datasets.

What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
