Full Analysis
  • [INDIRECT_PROMPT_INJECTION]: The skill enables an agent to browse and interact with external, untrusted web content which can be used to influence agent behavior.\n
  • Ingestion points: Interaction with untrusted web content occurs through the page.goto(url) method and subsequent AI-driven interactions like page.act() and page.extract() (found in SKILL.md).\n
  • Boundary markers: The skill suggests quoting literal text in instructions, but lacks explicit delimiters or instructions to the agent to ignore commands embedded in the data-plane (found in SKILL.md).\n
  • Capability inventory: The skill provides browser automation capabilities including navigation, element interaction, and structured data extraction from arbitrary URLs (found in SKILL.md).\n
  • Sanitization: No mechanisms are described for sanitizing the text or HTML content of target websites before it is processed by the underlying AI model (found in SKILL.md).\n- [EXTERNAL_DOWNLOADS]: The skill relies on external libraries for its core browser automation functionality.\n
  • Dependencies: Uses the stagehand and @browserbasehq/stagehand packages, which are the official libraries for the Stagehand automation framework, as well as the zod library for schema validation.
