AI agents call describe_survey to retrieve information from Emovi without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries descriptive information about a survey dataset. It has no capability to modify, delete, execute code, or perform financial operations. The action is read-only and informational, matching the Read category profile. The low severity reflects minimal blast radius if misused—an AI agent can only access overview information without risk of data corruption or unintended consequences.
From the tool's definition Tool name 'describe_survey' and description 'Get an overview of the ESRU-EMOVI 2023 social mobility survey' indicate retrieval and querying of survey metadata with no side effects.
