xcode-toolchain-trace
description (verbatim frontmatter)
Trace the real installed Xcode toolchain before acting — the SDKs, the xcrun command surface (build/test/simulate/sign/distribute), and the native Xcode Source Editor Extension ecosystem. Copycat-first: probe `xcodebuild -version`, `-showsdks`, and `xcrun --find <tool>`; never recall a version. Grounded in the vendored theswiftdev/awesome-xcode-extensions list. Use when the user asks to build/test/sign/distribute an Xcode project, which SDKs/tools are installed, how to run the simulator, notarize or upload a build, or which Xcode editor extensions exist for formatting/CodingKeys/lint. Trigger on "Xcode", "xcodebuild", "xcrun", "SDK", "simulator", "simctl", "notarize", "TestFlight", "provisioning", "Xcode extension". Do NOT use for Swift language/package work (cwc-swift-engineering) or device-hardware introspection (cwc-hardware-engineering).
summary
