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 | $0.00188 | $0.02271 |
| Opus 5 | $0.00094 | $0.01136 |
| Sonnet 5 | $0.00038 | $0.00454 |
| Haiku 4.5 | $0.00019 | $0.00227 |
Grade A, and why
ios-development 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 6d 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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Development Skill
Quick orientation
Before anything else, identify:
- UI framework → SwiftUI / UIKit / mixed?
- Architecture → MVVM / TCA / VIPER / Clean / MVC?
- iOS target → iOS 16 / 17 / 18? (affects API availability)
- Task type → new feature / debug / refactor / architecture / performance / release?
- Graphics intensity → стандартный UI / средняя 3D / тяжёлая графика / Metal?
Если задача связана с Metal, GPU, рендерингом, шейдерами, TBDR, MetalFX, GPU profiling, frame pacing, PSO, heaps, ICB, MTLIO → читать references/metal-graphics.md первым.
Then read the relevant reference file before writing code.
Reference files — read when needed
| Topic | File | When to read |
|---|---|---|
| SwiftUI pipeline | references/swiftui.md |
SwiftUI views, state, bindings, modifiers, animations |
| UIKit pipeline | references/uikit.md |
UIViewController, Auto Layout, delegates, storyboards |
| Architecture | references/architecture.md |
MVVM, TCA, VIPER, Clean, Coordinator |
| Networking | references/networking.md |
URLSession, async/await, REST/GraphQL, auth |
| Data persistence | references/data.md |
CoreData, SwiftData, UserDefaults, Keychain, FileManager |
| Navigation | references/navigation.md |
NavigationStack, Coordinator, deep links, sheets |
| Performance | references/performance.md |
Instruments, memory, launch time, rendering |
| Metal & Heavy Graphics | references/metal-graphics.md |
Metal, GPU рендер, TBDR, PSO/heaps/argument buffers, ICB, MTLIO, MetalFX, терморегуляция, профилирование GPU |
iOS version matrix (API availability)
| Feature | Min iOS |
|---|---|
| SwiftUI | iOS 13 |
async/await |
iOS 15 |
| NavigationStack | iOS 16 |
| SwiftData | iOS 17 |
@Observable macro |
iOS 17 |
| RippleEffect, ScrollView phases | iOS 18 |
Always check target before using newer APIs. Use #available guards for backward compatibility:
if #available(iOS 17, *) {
// SwiftData or @Observable
} else {
// fallback
}
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.

ios-development is a skill published in the GitHub repository AnastasiyaW/codex-claude-code-config (147 stars, last pushed today), licensed MIT. It adds 188 tokens to every session and 2,271 once invoked, about $0.0009 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.
