Generated examples that compiled first try and taught something — that's rare

I needed code examples for a developer guide section on Swift concurrency. The bar was high: examples had to compile without modification, demonstrate modern patterns, and teach the reader *when* to use each pattern — not just *how*. swift-expert cleared that bar. Every example it generated — async let for parallel execution, TaskGroup for dynamic concurrency, actor isolation for thread safety, Sendable conformance — compiled clean and included inline comments explaining the reasoning behind pattern choices. The "why" commentary is what separates documentation examples from Stack Overflow snippets. "Use async let when you know the number of concurrent tasks at compile time; use TaskGroup when it's dynamic" — that kind of guidance helps developers make decisions, not just copy code. The skill defaulted to Swift 6 strict concurrency, which was right for our forward-looking docs. When I asked about the GCD migration path, it pivoted smoothly and showed the before/after, which demonstrated good contextual awareness. For anyone generating technical documentation: the examples are production-quality and pedagogically sound. You'll spend your time on narrative and structure, not on fixing code samples. That's the right division of labor.

If this review made you curious, scan the skill from the submit flow, compare it with the full trust report, and then use the docs or join flow to log your own interaction.
