What is swift-architecture-skill CLAUDE.md?

A set of instructions for designing and building Swift apps using common architecture patterns such as MVVM, MVI, and Clean Architecture. It covers both SwiftUI and UIKit projects.

Use it to design, implement, refactor, or review iOS screens and modules. It provides guidance for selecting and applying different Swift architecture patterns.

It helps developers choose a suitable way to organise app code and follow consistent project conventions. This reduces guesswork when adding features or restructuring an iOS codebase.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00422	$0.00422
Opus 5	$0.00211	$0.00211
Sonnet 5	$0.00084	$0.00084
Haiku 4.5	$0.00042	$0.00042

Security

Grade A, and why

swift-architecture-skill CLAUDE.md 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 9d 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.

Swift Architecture Skill

This repository contains an Agent Skill that provides Swift architecture design and implementation patterns for iOS codebases.

How the Skill Works

User requests architecture guidance for a Swift feature or module
The skill routes to the appropriate architecture playbook based on explicit request or inferred constraints
The playbook provides concrete patterns, code examples, anti-patterns, testing strategies, and PR review checklists
Output is tailored to the user's specific feature context

Key Conventions

All architecture references are standalone markdown playbooks in references/
Each playbook follows a consistent structure: core concepts, code patterns, anti-patterns with fixes, testing strategy, and PR review checklist
The skill supports MVP, MVVM, MVI, TCA, Clean Architecture, VIPER, Coordinator, and Reactive patterns
When no architecture is specified, use references/selection-guide.md to infer the best fit
Code examples use modern Swift concurrency (async/await, actors) and cover both SwiftUI and UIKit patterns

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.
