The Agent Skills Directory

Indirect Prompt Injection (LOW): The skill possesses a surface for indirect prompt injection because it ingests data from external URLs via Playwright and generates markdown for an agent to process.
Ingestion points: capture-screenshots.js visits the url parameter provided via command-line arguments.
Boundary markers: None present in the generated markdown output.
Capability inventory: The script can write to the local filesystem (writeFile, mkdir) and perform network requests to any URL via Playwright.
Sanitization: No sanitization of the content of the captured pages is performed, which is expected for a screenshot tool.
External Downloads (SAFE): The skill depends on playwright, a standard and trusted package maintained by Microsoft.
File System Operations (SAFE): The script writes screenshots and markdown files to a directory specified by the caller. While the outputDir is user-controllable, which can lead to path traversal in some environments, it is a standard functional requirement for this utility.
