Full Analysis
- [DYNAMIC_EXECUTION]: The skill provides an
executefunction that allows for the execution of arbitrary JavaScript code within the browser context. While this is a core feature for web automation, it represents a significant dynamic execution surface. - [INDIRECT_PROMPT_INJECTION]: The skill is designed to navigate and extract data from external websites. This content is untrusted and could contain malicious instructions intended to manipulate the agent's behavior.
- Ingestion points: The
open,snapshot, andexecutefunctions all ingest content from external URLs (found inSKILL.mdandreferences/commands.md). - Boundary markers: The skill does not implement specific delimiters or warnings for the agent to ignore instructions embedded in the extracted web content.
- Capability inventory: The skill possesses powerful capabilities including arbitrary JavaScript execution (
execute), element interaction (interact), and file uploads (interactwithuploadaction). - Sanitization: There is no evidence of sanitization or filtering of the content extracted from web pages before it is presented to the agent.
- [DATA_EXFILTRATION]: The documentation explicitly provides examples and instructions for using JavaScript to extract sensitive session information, such as cookies, from the browser environment (found in
references/authentication.md).
