    "description": "Trace the real Swift stack the Claude apps and this repo already ship — the language, the SwiftPM package graph, and the frameworks — before writing new Swift. Copycat-first groundwork: read the actual sources, don't invent. Covers the house ClaudeAPI Messages client (Configuration/MessagesRequest/SSEParser), the ClaudeForFoundationModels bridge package layout, the official modelcontextprotocol/swift-sdk dependency, and the one hard rule — the wire shape is shared across four languages (Swift CodingKeys mirror serde/Pydantic/ Zod). Use when the user asks to build/extend Swift code, map a SwiftPM graph, touch CodingKeys/Codable, work with Swift concurrency or SSE, or understand the real Swift surface. Trigger on \"Swift\", \"SwiftPM\", \"swift package\", \"CodingKeys\", \"Codable\", \"async/await Swift\", \"SSE parser\". Do NOT use for device hardware (cwc-hardware-engineering), the Xcode toolchain (cwc-xcode-engineering), or Cloudflare deploys.",
