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 | $0.00051 | $0.01698 |
| Opus 5 | $0.00026 | $0.00849 |
| Sonnet 5 | $0.00010 | $0.00340 |
| Haiku 4.5 | $0.00005 | $0.00170 |
Grade A, and why
ios-dev 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Development
Start here. This skill coordinates the Apple skills collection — it tells you which skill to use and when, so you get opinionated guidance and full API references together.
Operating Rules
- SwiftUI and UIKit are both first-class — pick whichever fits the task. UIKit is a valid choice whenever it gives more control or flexibility; when bridging the two, watch state sync, lifecycle, and animation/environment boundaries.
- Do not enforce specific architectures (MVVM, VIPER, MV, TCA, etc.) — encourage separating business logic from views without mandating how
- Hold a high bar for UI craft: apps should feel current-generation — fluid, design-forward, alive. Sweat the tiny details. Custom components, novel interactions, and custom Metal shaders are all in-bounds when they serve the experience; system defaults are a floor, not a ceiling.
- Do not prescribe how that craft is delivered — no house style, no "Apple-approved" gatekeeping, no aesthetic checklists. Design direction is your own judgment call, made per app. The
higandios-liquid-glassskills document what the system provides; they are references, not style mandates. When the task is designing a screen or making it look good, there is no doc to route to — design from your own taste; grep references only when you need API mechanics or a factual minimum (e.g. hit-target sizes). - Present performance optimizations as suggestions backed by reasoning, not blanket requirements
- When you need exact API details, grep the framework reference skills — they contain full Apple documentation
Task Workflows
Review existing code
- Read the code and identify which topics apply
- Run the Correctness Checklist below — violations are bugs
- Use the Topic Router to load the relevant guide for each topic
- For API correctness, grep the matching framework reference skill
Improve existing code
- Run the correctness checklist first
- For performance issues: use
guide-swiftui-performance-audit - For navigation, state, or pattern questions: use
guide-swiftui-ui-patterns - For API details: grep the matching framework reference skill
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.
- 4d ago First seen · 114 lines · 51 tokens per session scan A 83898bc10e30
ios-dev is a skill published in the GitHub repository Prisma-Labs-Dev/apple-skills (323 stars, last pushed 23d ago), licensed MIT. It adds 51 tokens to every session and 1,698 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 2026-08-30.
