Risk Level: SAFEPROMPT_INJECTIONNO_CODE
Full Analysis
  • [PROMPT_INJECTION]: The skill is vulnerable to indirect prompt injection because it processes untrusted data from Gmail messages while possessing capabilities to perform sensitive actions.
  • Ingestion points: Untrusted data enters the agent's context through message reading and searching functions (e.g., searchMessages).
  • Boundary markers: The skill documentation lacks explicit instructions for the agent to treat email content as untrusted or to ignore instructions embedded within the text of messages.
  • Capability inventory: The skill allows sending emails (sendEmail) and grants read access to the local filesystem (./** via tank.json), creating a path for data exfiltration if the agent is manipulated.
  • Sanitization: There is no evidence of filtering or sanitization of email body content to prevent command-like structures from influencing the agent's behavior.
  • [NO_CODE]: The skill consists solely of instructions (SKILL.md) and configuration (tank.json) without any accompanying scripts or executables, which reduces the surface area for direct malicious code execution.
