WHAT IT DOES

What list_review_candidates does on Businys

AI agents call list_review_candidates to retrieve information from Businys without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_review_candidates is rated Low

This tool retrieves and filters historical invoice data to identify client prospects. It reads existing records without creating, modifying, deleting, or executing external actions. The data returned is already public/internal business information. Risk is minimal: worst case, an agent misuses results to send unsolicited review requests, but the tool itself causes no irreversible harm.

From the tool's definition Tool description states 'Find clients' and 'Returns clients with paid invoices' — purely a query/retrieval operation with no modifications or side effects.
