AI agents call list_answers to retrieve information from Yanifend 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 collected feedback data without creating, modifying, or deleting any information. The use of 'pull' and 'list' indicates a read-only operation. While the data retrieved may be sensitive (user feedback), the tool itself performs no irreversible actions and has minimal blast radius if misused by an agent—it would only expose existing data that an authenticated user already has access to.
From the tool's definition Tool name 'list_answers' with description 'Pull the latest collected answers for a personage' indicates data retrieval with no modification or side effects.
