AI agents call get_locked_votes to retrieve information from Justlend without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves voting information about a specific user and proposal without modifying any state, creating obligations, or executing code. It is a straightforward read operation on blockchain data. The low severity reflects minimal blast radius if misused—an agent could only retrieve existing vote data, not alter governance outcomes or access unauthorized information.
From the tool's definition Tool name 'get_locked_votes' and description 'Get the number of votes a user has locked in a specific proposal' indicate a query/retrieval operation with no side effects.
