ios-knowledge-skill

ios-knowledge-skill is a skill for Claude Code, Codex from adilkalam/orca. It costs 47 tokens per session (865 once invoked), scanned A, original, MIT.

An iOS development reference for choosing app architectures, data storage, and current Apple development standards. It covers SwiftUI, UIKit, and common patterns such as MVVM and TCA.

In plain words
What is it for?
Use it when planning or reviewing iOS app structure, navigation, dependencies, data models, concurrency, testing, or security.
Why use it?
It gives coding agents shared context for making iOS design and architecture decisions instead of repeating that background in every prompt.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ios-knowledge-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 1mo 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.

iOS Knowledge Skill – Architecture & Patterns

This skill equips agents with high-level iOS knowledge for the OS 7.0 iOS lane without bloating individual agent prompts.

It is intended for:

  • ios-grand-architect
  • ios-architect
  • Core iOS specialists (SwiftUI/UIKit/persistence/networking/testing/perf/security) when they need architectural context.

Context7 Libraries

When you load this skill, you MAY use context7 MCP tools to read from:

  • os2-ios-architecture

    • SwiftUI vs UIKit vs mixed stack guidance,
    • MVVM/TCA/Clean patterns for iOS,
    • Navigation, modularization, and dependency injection strategies.
  • os2-ios-standards

    • Coding standards for the iOS lane,
    • Error handling and logging patterns,
    • Guidelines for concurrency, testing, and app structure.
  • /websites/developer_apple_swiftdata (via Context7)

    • SwiftData models with @Model, @Relationship, cascade deletes
    • Preferred over Core Data for iOS 17.0+ projects
    • In-memory testing with ModelContainer
    • Native, zero-dependency persistence
  • /ra1028/swiftui-atom-properties (via Context7)

    • Atomic state management for complex cross-feature coordination
    • StateAtom, ValueAtom, ObservableObjectAtom patterns
    • Testing with AtomTestContext
    • Compile-safe dependency injection
  • /pointfreeco/swift-navigation (via Context7)

    • State-driven navigation with @CasePathable enums
    • Sheet/modal presentation tied to model state
    • Deep linking and state restoration
    • Two-way bindings for navigation state

You SHOULD:

  • Read only the sections relevant to the current task,
  • Summarize 3–7 key constraints or patterns into your own working context,
  • Avoid loading large example sections unless explicitly needed.

Usage Pattern

  1. When planning an iOS task:
    • Load ios-knowledge-skill and skim the relevant context7 docs.
    • Extract:
      • Recommended UI stack (SwiftUI vs UIKit/TCA/MVVM),
      • Data strategy hints (SwiftData vs Core Data/GRDB),
      • Lane-specific constraints (design DNA/tokens, concurrency rules).

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-knowledge-skill is a skill published in the GitHub repository adilkalam/orca (2 stars, last pushed 2mo ago), licensed MIT. It adds 47 tokens to every session and 865 once invoked, about $0.0002 per session on Opus 5.5. 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.
