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 | $0.00080 | $0.02092 |
| Opus 5 | $0.00040 | $0.01046 |
| Sonnet 5 | $0.00016 | $0.00418 |
| Haiku 4.5 | $0.00008 | $0.00209 |
Grade A, and why
ios-app-builder 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 10d 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 — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Development
Build iOS applications following Apple's official architecture guidance, modern Swift concurrency patterns, and SwiftUI best practices.
Quick Reference
| Task | Reference File |
|---|---|
| Architecture layers (UI, Domain, Data) | architecture.md |
| SwiftUI patterns & navigation | swiftui-patterns.md |
| Swift Actors & concurrency | actors.md |
| Project & build configuration | project-setup.md |
| Project structure & modules | modularization.md |
| Testing approach | testing.md |
Workflow Decision Tree
Creating a new project?
→ Read project-setup.md for SPM and Xcode setup
→ Read modularization.md for module structure
→ Use templates in assets/templates/
Adding a new feature? → Create feature module following modularization.md → Follow patterns in architecture.md
Building UI screens? → Read swiftui-patterns.md → Create Route + Screen + ViewModel
Setting up data layer? → Read data layer section in architecture.md → Create Repository protocol + actor implementation + @ModelActor
Working with concurrency? → Read actors.md for actors, Sendable, async/await → Follow the actor decision tree
Writing tests? → Read testing.md → Use Swift Testing framework with protocol-based test doubles
Core Principles
- Offline-first: Local persistence (SwiftData) is source of truth, sync with remote
- Unidirectional data flow: Events flow down, data flows up
- Reactive streams: Use AsyncSequence/AsyncStream for all data exposure
- Modular by feature: Each feature is self-contained via Swift Package modules
- Testable by design: Use protocols and test doubles, no mocking libraries
- Actor-isolated concurrency: Use actors for shared mutable state, @MainActor for UI
What ships with it

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-app-builder is a skill published in the GitHub repository mouchegmouradian/claude-code-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 80 tokens to every session and 2,092 once invoked, about $0.0004 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 2026-08-31.
