Full Analysis
  • [PROMPT_INJECTION]: The skill exhibits an indirect prompt injection surface.\n
  • Ingestion points: The agent is instructed to retrieve and display external submission data using the GET /api/forms/{form_id}/submissions endpoint (as documented in references/api.md).\n
  • Boundary markers: There are no instructions in SKILL.md to wrap external submission data in delimiters or to ignore potential instructions embedded within that data.\n
  • Capability inventory: The skill allows the agent to perform state-changing operations such as creating, updating, or deleting forms and knowledge bases via curl commands to the vendor's API (SKILL.md).\n
  • Sanitization: The instructions do not specify any sanitization, filtering, or validation of the external content before it is processed by the agent.
