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.

If the Sosumi CLI is available, quickly verify local access before deeper debugging:

Replace developer.apple.com with sosumi.ai:

Pattern: https://sosumi.ai/documentation/{framework}/{symbol}
Examples:
- https://sosumi.ai/documentation/swift/array
- https://sosumi.ai/documentation/swiftui/view

Pattern: https://sosumi.ai/design/human-interface-guidelines/{topic}
Examples:
- https://sosumi.ai/design/human-interface-guidelines
- https://sosumi.ai/design/human-interface-guidelines/foundations/color

Pattern: https://sosumi.ai/videos/play/{collection}/{id}
Examples:
- https://sosumi.ai/videos/play/wwdc2021/10133
- https://sosumi.ai/videos/play/meet-with-apple/208

Pattern: https://sosumi.ai/external/{full-https-url}
Examples:
- https://sosumi.ai/external/https://apple.github.io/swift-argument-parser/documentation/argumentparser/
- https://sosumi.ai/external/https://swiftpackageindex.com/pointfreeco/swift-composable-architecture/1.23.1/documentation/composablearchitecture

Use these when Sosumi is configured as an MCP server (https://sosumi.ai/mcp):

Tool	Parameters	Use
`searchAppleDocumentation`	`query: string`	Search Apple documentation and return structured results
`fetchAppleDocumentation`	`path: string`	Fetch Apple docs or HIG content by path as Markdown
`fetchAppleVideoTranscript`	`path: string`	Fetch Apple video transcript by `/videos/play/...` path
`fetchExternalDocumentation`	`url: string`	Fetch external Swift-DocC page by absolute HTTPS URL

Search first if the exact path is unknown.
Fetch targeted symbol pages for coding questions.
Keep source links in answers so users can verify details quickly.
Use Sosumi paths directly in responses whenever referencing Apple documentation pages.
