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 | $0.00062 | $0.03032 |
| Opus 5 | $0.00031 | $0.01516 |
| Sonnet 5 | $0.00012 | $0.00606 |
| Haiku 4.5 | $0.00006 | $0.00303 |
Grade A, and why
swiftui-expert-skill 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.

SwiftUI Expert Skill
Overview
Use this skill to build, review, or improve SwiftUI features with correct state management, optimal view composition, and iOS 26+ Liquid Glass styling. Prioritize native APIs, Apple design guidance, and performance-conscious patterns. This skill focuses on facts and best practices without enforcing specific architectural patterns.
Workflow Decision Tree
1) Review existing SwiftUI code
- First, consult
references/latest-apis.mdto ensure only current, non-deprecated APIs are used - Check property wrapper usage against the selection guide (see
references/state-management.md) - Verify view composition follows extraction rules (see
references/view-structure.md) - Check performance patterns are applied (see
references/performance-patterns.md) - Verify list patterns use stable identity (see
references/list-patterns.md) - Check animation patterns for correctness (see
references/animation-basics.md,references/animation-transitions.md) - Review accessibility: proper grouping, traits, Dynamic Type support (see
references/accessibility-patterns.md) - Inspect Liquid Glass usage for correctness and consistency (see
references/liquid-glass.md) - Validate iOS 26+ availability handling with sensible fallbacks
2) Improve existing SwiftUI code
- First, consult
references/latest-apis.mdto replace any deprecated APIs with their modern equivalents - Audit state management for correct wrapper selection (see
references/state-management.md) - Extract complex views into separate subviews (see
references/view-structure.md) - Refactor hot paths to minimize redundant state updates (see
references/performance-patterns.md) - Ensure ForEach uses stable identity (see
references/list-patterns.md) - Improve animation patterns (use value parameter, proper transitions, see
references/animation-basics.md,references/animation-transitions.md) - Improve accessibility: use
Buttonover tap gestures, add@ScaledMetricfor Dynamic Type (seereferences/accessibility-patterns.md) - Suggest image downsampling when
UIImage(data:)is used (as optional optimization, seereferences/image-optimization.md) - Adopt Liquid Glass only when explicitly requested by the user
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.

swiftui-expert-skill is a skill published in the GitHub repository hainamchung/agent-assistant (54 stars, last pushed 3mo ago), licensed MIT. It adds 62 tokens to every session and 3,032 once invoked, about $0.0003 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.
