Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill instructs the user to install
expect-cliglobally usingnpm install -g expect-cli. This package is provided by an unverified third-party vendor ('millionco'). - [REMOTE_CODE_EXECUTION]: The installation of the
expect-clipackage from an unverified source represents a supply chain risk, as the package executes with the permissions of the user during installation and subsequent use. - [DATA_EXFILTRATION]: The tool records browser sessions and handles 'cookie/auth injection'. It references an external host
https://expect.devfor session replays and sends telemetry to PostHog. The handling of authentication data in conjunction with external network references requires caution. - [COMMAND_EXECUTION]: The primary function of the skill is to execute the
expect-clicommand with natural language instructions, which grants the tool control over browser environments. - [INDIRECT_PROMPT_INJECTION]:
- Ingestion points: The skill takes natural language input via the
-mor--messageflag to define test plans. - Boundary markers: None; instructions are passed directly to the CLI.
- Capability inventory: The tool can inject cookies, record sessions, and perform arbitrary browser actions.
- Sanitization: The skill does not describe any sanitization or validation of the instructions passed to the browser automation engine.
