Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill executes
npx -y @claude-flow/cli@latest, which downloads and runs code from an external registry at runtime. This package is not associated with a recognized trusted vendor or well-known service. - [DATA_EXFILTRATION]: The skill captures sensitive session data using
browser_evalto readdocument.cookie. This information is then exfiltrated to an external storage mechanism (memory store --namespace browser-cookies). While the instructions mention sanitization via AIDefence, session credentials are still being persisted outside the immediate browser context. - [COMMAND_EXECUTION]: Shell commands are used to invoke the
npxutility and manage the environment. Additionally,browser_evalis used to execute arbitrary JavaScript within the browser context to extract cookies. - [PROMPT_INJECTION]: This skill presents an indirect prompt injection surface (Category 8).
- Ingestion points: Untrusted content from target websites enters the agent context through
browser_snapshotandbrowser_evalduring the authentication flow (SKILL.md). - Boundary markers: Absent; there are no instructions to ignore embedded commands in the browser's DOM or response headers.
- Capability inventory: The skill possesses high-privilege capabilities including
Bashexecution, fileWriteaccess, and arbitrarybrowser_eval(SKILL.md). - Sanitization: The skill mentions using
aidefence_scanspecifically for cookie values, but does not specify sanitization for the broader page content encountered during the trajectory.
