The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions for users to download the @nshipster/sosumi CLI package from the official NPM registry and the SKILL.md file from the project's own domain, sosumi.ai.
[COMMAND_EXECUTION]: Documentation includes instructions for users to run standard installation and execution commands using package managers (npm, bun, deno) and the npx utility for interacting with the service.
[DATA_EXFILTRATION]: Documentation requests are directed from developer.apple.com to sosumi.ai. This is the core design feature of the service to facilitate AI-readable documentation rendering.
[SAFE]: Zero-width spaces () are used in the index.html file to assist with text wrapping of long URLs in the UI, which is a benign layout practice. A Cursor deep link contains a base64-encoded configuration string for server setup.
[PROMPT_INJECTION]: The skill has an indirect ingestion surface as it processes external documentation content.
Ingestion points: fetchExternalDocumentation and fetchAppleDocumentation tools.
Boundary markers: Not specified in the instructions.
Capability inventory: The skill is a data provider and lacks capabilities for local file system writes or subprocess execution beyond the documented search/fetch operations.
Sanitization: Not explicitly defined within the skill instructions.
