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

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

HTTP Usage

Replace
developer.apple.com
with
sosumi.ai

MCP Tools Quick Reference

):
ToolParametersUse
searchAppleDocumentation

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.txt
    or
    X-Robots-Tag
    directives.
  • Try another canonical page URL for the same symbol.
