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)
Core Workflow
- If you already have a
developer.apple.comURL, replace the host withsosumi.aiand 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.
HTTP Usage
Replace developer.apple.com with sosumi.ai:
- Original:
https://developer.apple.com/documentation/swift/array - AI-readable:
https://sosumi.ai/documentation/swift/array
Content Types
Apple API Reference
- Pattern:
https://sosumi.ai/documentation/{framework}/{symbol} - Examples:
- https://sosumi.ai/documentation/swift/array - https://sosumi.ai/documentation/swiftui/view
Human Interface Guidelines
- 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
Apple Video Transcripts
- 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
External Swift-DocC
- 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
MCP Tools Quick Reference
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 |
Best Practices
- 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.
Troubleshooting
404 or sparse output
- The path may be incorrect or too broad.
- Run a search query first, then fetch a specific result path.
External page cannot be fetched
- The host may block access via
robots.txtorX-Robots-Tagdirectives. - Try another canonical page URL for the same symbol.
