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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00162 | $0.01097 |
| Opus 5 | $0.00081 | $0.00549 |
| Sonnet 5 | $0.00032 | $0.00219 |
| Haiku 4.5 | $0.00016 | $0.00110 |
Grade A, and why
hig-components-system 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 13d 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.

Apple HIG: System Experiences
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
-
Glanceable, immediate value. System experiences bring your app's most important content to surfaces the user sees without launching your app. Design for seconds of attention.
-
Respect platform context. A Lock Screen widget has different constraints than a Home Screen widget. A complication is far smaller than a top shelf item.
-
Widgets: show relevant information, not everything. Display the most useful subset, updated appropriately.
-
Support multiple widget sizes with distinct layouts. Each size should be a thoughtful design, not a scaled version of another.
-
Deep-link on tap. Take users to the relevant content, not the app's root screen.
-
Live Activities: track events with a clear start and end. Deliveries, scores, timers, rides. Design for both Dynamic Island and Lock Screen.
-
Stay updated and timely. Stale data undermines trust. End promptly when the event concludes.
-
Respect user attention with notifications. Only send notifications for information users genuinely care about. No promotional or low-value notifications.
-
Notifications: actionable and self-contained. Include enough context to understand and act without opening the app. Support notification actions. Use threading and grouping.
-
Complications: focused data on the watch face. Design for the smallest useful representation. Support multiple families. Budget updates wisely.
-
Home Screen quick actions: 3-4 most common tasks. Short titles, optional subtitles, relevant SF Symbol icons.
-
Top Shelf: tvOS showcase. Feature content that entices: new episodes, featured items, recent content.
-
App Clips: instant, focused functionality within a strict size budget. Load quickly without App Store download. Only what's needed for the immediate task, then offer full app install.

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.
