Full Analysis
  • [COMMAND_EXECUTION]: The skill uses a JavaScript tool to inject a helper file input element and simulate a clipboard paste event within the browser context, which is necessary to bypass standard interface limitations.
  • [EXTERNAL_DOWNLOADS]: The skill facilitates uploading local media files to the gemini.google.com domain. As Google is a well-known service, this is considered intended functionality, and the skill includes an advisory to obtain user consent before uploading data.
  • [PROMPT_INJECTION]: The skill reads external data from the Gemini web interface, creating a vulnerability surface for indirect prompt injection.
  • Ingestion points: The agent context is updated with untrusted data when polling the analysis result using the get_page_text tool in SKILL.md.
  • Boundary markers: The instructions do not define any delimiters or warnings to ignore instructions contained within the retrieved page text.
  • Capability inventory: The skill possesses extensive capabilities including browser navigation, JavaScript execution, and local file upload via the claude-in-chrome server.
  • Sanitization: No sanitization, filtering, or validation is performed on the data ingested from the browser session.
