Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill instructs the user to install an external global NPM package agent-browser and run an installation script (agent-browser install) which typically downloads browser binaries (Chromium).
  • [DYNAMIC_EXECUTION]: The skill functions as a 'discovery stub' that does not contain the actual operational instructions. It directs the agent to dynamically load workflows, command references, and templates at runtime from a remote source using the agent-browser skills get command.
  • [INDIRECT_PROMPT_INJECTION]: As a browser automation tool, the agent processes accessibility-tree snapshots and page content from arbitrary, untrusted websites. This content can contain adversarial instructions intended to hijack the agent's session.
  • Ingestion points: Accessibility-tree snapshots and web page data in SKILL.md (via CLI output).
  • Boundary markers: None provided in this discovery stub.
  • Capability inventory: Subprocess execution via Bash, session management, and access to an 'authentication vault'.
  • Sanitization: Not explicitly defined in the instruction stub.
  • [COMMAND_EXECUTION]: The skill relies on shell command execution to interact with the browser CLI, manage sessions, and fetch remote skill content.
