Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill requires the installation of the @membranehq/cli package from the public NPM registry. This is a vendor-provided tool used for authentication and API communication.
  • [COMMAND_EXECUTION]: The instructions involve executing several shell commands using the membrane CLI to log in, establish connections, and perform calendar operations.
  • [INDIRECT_PROMPT_INJECTION]: The skill acts as a bridge to external data from Google Calendar, creating an attack surface for indirect prompt injection.
  • Ingestion points: Data retrieved from membrane action list, membrane action run, and membrane request (e.g., event descriptions, calendar names) is ingested into the agent's context (SKILL.md).
  • Boundary markers: The skill lacks explicit instructions or delimiters to warn the agent about potentially malicious content within the external data.
  • Capability inventory: The agent has the capability to execute shell commands and perform network operations via the provided CLI (SKILL.md).
  • Sanitization: No sanitization or content filtering is implemented for the data fetched from the external API.
