Why clear_all_datasets is rated Critical
This tool irreversibly removes data (all datasets) from the system's memory with no apparent undo mechanism. The blast radius is high because an AI agent invoking this without intent could permanently lose all cached or indexed datasets that power the RAG system, directly undermining the core functionality of the knowledge base.
From the tool's definition Tool name 'clear_all_datasets' combined with description 'Clear all datasets from memory' indicates irreversible deletion of data. The term 'clear' in this context means to wipe or purge, and 'all datasets' indicates a bulk destructive operation.
