Full Analysis
- [INDIRECT_PROMPT_INJECTION]: The skill is designed to navigate and extract data from arbitrary external URLs, creating a surface for indirect prompt injection where malicious websites could attempt to override agent instructions.
- Ingestion points: The
openandsnapshotfunctions (found inSKILL.mdandreferences/commands.md) ingest data from external websites into the agent's context. - Boundary markers: The skill does not provide explicit delimiters or instructions for the agent to ignore instructions embedded in the target website's content.
- Capability inventory: The skill possesses extensive capabilities, including element interaction (
click,fill,upload), arbitrary JavaScript execution (execute), and session recording (record_video). - Sanitization: There is no evidence of sanitization or filtering of the content retrieved from external websites before it is presented to the agent.
- [DYNAMIC_EXECUTION]: The skill provides an
executefunction (documented inreferences/commands.md) that allows the agent to run arbitrary JavaScript code within the browser session. While this is a core feature for web automation, it represents a high-capability tool that could be misused if the agent is misled by malicious content. - [DATA_EXFILTRATION]: The documentation in
references/authentication.mddescribes how to use theexecutefunction to extract browser cookies (document.cookie), which could be used to exfiltrate session data if the agent is directed to do so by an attacker. - [EXTERNAL_DOWNLOADS]: The skill instructions in
SKILL.mdand templates recommend installing thebeltCLI and related skills usingnpx skills add, which involves downloading and executing third-party packages. - [COMMAND_EXECUTION]: The authentication patterns in
references/authentication.mdinclude shell command execution for generating TOTP codes via theoathtoolutility.
