Sosumi Skill

Use this skill to reliably fetch Apple docs as Markdown when coding agents need precise API details.

When to Use

Use Sosumi when the request involves any of the following:

Apple platform APIs (Swift, SwiftUI, UIKit, AppKit, Foundation, etc.)
API signatures, availability, parameter behavior, or return semantics
Human Interface Guidelines questions
WWDC session transcript lookup
External Swift-DocC documentation (for example, GitHub Pages or Swift Package Index hosts)

If you already have a developer.apple.com URL, replace the host with sosumi.ai and keep the same path.
If you do not know the exact page path, search first, then fetch the best match.
Prefer specific symbol pages instead of broad top-level pages when answering implementation questions.
