Risk Level: SAFEEXTERNAL_DOWNLOADSCOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill installs the
@membranehq/clipackage from NPM. This is a vendor-provided tool from the author (Membrane) and is considered a safe dependency for the intended purpose of the skill. - [COMMAND_EXECUTION]: The instructions utilize shell commands through the
membraneCLI to manage connections and execute actions. These commands are part of the core functionality of the skill and do not include arbitrary or dangerous execution patterns. - [PROMPT_INJECTION]: The skill presents an indirect prompt injection surface as it processes external survey data and responses from Formbricks.
- Ingestion points: Data is ingested via the
membrane action runcommand (e.g., listing responses or people) inSKILL.md. - Boundary markers: The provided instructions do not specify the use of delimiters or 'ignore' instructions when the agent processes the retrieved survey content.
- Capability inventory: The skill allows the agent to create and run actions via the CLI, providing a path for influence if survey data contains malicious instructions.
- Sanitization: There is no mention of sanitization or filtering of the survey data before it is processed by the agent.
