This tool retrieves and queries previously scraped Reddit data stored locally. It has no side effects, does not modify or delete data, does not execute code, and does not involve financial operations. It is a straightforward search/query operation on cached data, making it a Read category tool with low severity risk.
From the tool's definition Tool description states 'Search across all scraped Reddit data' and 'finding specific topics or trends' — purely retrieval operations with no modification, deletion, or execution of external code.
