sosumi

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.

Optional CLI Preflight

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

• sosumi --version confirms the CLI is installed and on PATH.
• sosumi --help shows top-level usage.
• sosumi <command> --help is the manual for command-specific behavior.

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

MCP Tools Quick Reference

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

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.
