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 | $0.00017 | $0.01149 |
| Opus 5 | $0.00009 | $0.00575 |
| Sonnet 5 | $0.00003 | $0.00230 |
| Haiku 4.5 | $0.00002 | $0.00115 |
Grade A, and why
theme-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 8d 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.

Theme System Overview
This iOS Design System uses a centralized theme system with 8 color palettes, 22 typography styles, and automatic light/dark mode support.
Theme Access Pattern
Always access theme via context:
final theme = IosTheme.of(context);
Color Systems
1. System Colors (theme.defaultColors)
Standard iOS colors that adapt to brightness:
systemBlue,systemRed,systemGreen,systemYellow,systemOrangesystemPink,systemPurple,systemTeal,systemIndigosystemGray01throughsystemGray06systemBlack,systemWhite
2. Label Colors (theme.defaultLabelColors)
Semantic text colors:
primary- Main text (100% opacity)secondary- Secondary text (60% opacity)tertiary- Disabled text (30% opacity)quartenary- Placeholder (18% opacity)
3. Fill Colors (theme.defaultFillColors)
Background fills for UI elements:
primary,secondary,tertiary,quartenary- Auto-adapting opacity for light/dark
4. System Backgrounds (theme.defaultSystemBackgroundsColors)
Screen-level backgrounds:
primaryLight,primaryDarkBase,primaryDarkElevatedsecondaryLight,secondaryDarkBase,secondaryDarkElevatedtertiaryLight,tertiaryDarkBase,tertiaryDarkElevated
5. Grouped Backgrounds (theme.defaultSystemGroupedBackgroundsColors)
For Settings-style grouped lists (same structure as System Backgrounds)
6. Separator Colors (theme.defaultSeparatorColors)
opaque- Prominent bordersnonOpaque- List dividers (default)
7. System Materials
Colors for blur effects:

8. App Decorations

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.

theme-system is a skill published in the GitHub repository sampaio-tech/iOS-design-system (19 stars, last pushed 1mo ago), licensed MIT. It adds 17 tokens to every session and 1,149 once invoked, about $0.0001 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.
