CCG is a command-line workflow engine that coordinates Claude, Codex, Gemini, and other models as specialized collaborators on coding tasks. It is used to analyze requests, choose a strategy, delegate work to model-specific roles, and combine their results. The catalogue entries provide the skills, commands, agents, and plugin that implement this workflow.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.02520 |
| Opus 5 | $0.00022 | $0.01260 |
| Sonnet 5 | $0.00009 | $0.00504 |
| Haiku 4.5 | $0.00004 | $0.00252 |
Grade A, and why
mobile 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.
How it starts
The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.

iOS 开发
SwiftUI 核心模式
- View 组件：
struct MyView: View { var body: some View { ... } } - State 管理：
@State— 本地状态@Binding— 父子双向绑定@StateObject— 拥有 ObservableObject@ObservedObject— 引用 ObservableObject@EnvironmentObject/@Environment— 全局注入
- ObservableObject：
@Published属性自动触发 UI 更新 - Custom ViewModifier：
struct CardModifier: ViewModifier+extension View { func cardStyle() } - 生命周期：
.task { await ... }/.onAppear/.onDisappear
UIKit 集成
- UIViewControllerRepresentable：包装 UIViewController 到 SwiftUI
- UIViewRepresentable：包装 UIView 到 SwiftUI
- Coordinator 模式：处理 delegate 回调
- Auto Layout：
NSLayoutConstraint.activate([...])+translatesAutoresizingMaskIntoConstraints = false
Combine 响应式
- Publisher：
URLSession.shared.dataTaskPublisher→map→decode→eraseToAnyPublisher - 订阅：
.sink(receiveCompletion:receiveValue:)+.store(in: &cancellables) - 常用 Operators：
debounce/removeDuplicates/combineLatest/flatMap - Subject：
PassthroughSubject（无初始值）/CurrentValueSubject（有初始值）
iOS 架构
MVVM（推荐）：
- Model：
Codable数据结构 - Repository：
protocol+async throws方法 - ViewModel：
@MainActor class VM: ObservableObject+@Published属性 - View：
@StateObject private var viewModel = VM()
VIPER（复杂场景）：
- View ←→ Presenter ←→ Interactor → Entity
- Router 处理导航
网络层
- APIClient：泛型
func get<T: Decodable>(_ path:) async throws -> T - Token 管理：
request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization") - 错误处理：
enum APIError: Error { case invalidURL, invalidResponse, httpError(Int) }
数据持久化
- UserDefaults：
@propertyWrapper struct UserDefault<T>简化访问 - Keychain：
SecItemAdd/SecItemCopyMatching存储敏感数据 - Core Data：
NSPersistentContainer+NSManagedObjectContext - SwiftData（iOS 17+）：
@Model宏简化持久化
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.

mobile is a skill published in the GitHub repository fengshao1227/ccg-workflow (5,875 stars, last pushed 4d ago), licensed MIT. It adds 44 tokens to every session and 2,520 once invoked, about $0.0002 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.
