The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses a local script scripts/find-writing-assistance-targets.mjs to inventory the workspace and identify frontend files suitable for API integration. The script performs read-only file system operations using the Node.js runtime.
[EXTERNAL_DOWNLOADS]: The skill recommends installing the @types/dom-chromium-ai npm package to provide TypeScript definitions for the experimental browser APIs. This is a standard development dependency.
[PROMPT_INJECTION]: The skill implements APIs designed to process untrusted data, such as web page content and user input, which presents an indirect prompt injection surface.
Ingestion points: Data is ingested from the browser environment (e.g., article.innerText) as shown in references/examples.md and SKILL.md Step 4.
Boundary markers: No explicit delimiters are used in the examples, though the skill provides guidance on data handling.
Capability inventory: The skill utilizes the browser's built-in Summarizer, Writer, and Rewriter APIs. These operate within the browser sandbox and do not have access to the underlying operating system or file system.
Sanitization: Step 4.3 of the procedures in SKILL.md explicitly instructs to "Strip or normalize HTML before summarization or rewriting" to mitigate issues with rendered content.
