Splits total vendor spend across a category, showing how concentrated it is in the top vendor and flagging single-vendor dependency risk.
Adjust total spend and the top vendors' share — concentration above 40% in a single vendor is flagged.
| 1. Pull vendor ledger | Reads spend by vendor for the category from the iUL ledger via the Core Banking MCP server |
| 2. Rank vendors | Orders vendors by trailing 12-month spend and computes each share of the category |
| 3. Flag concentration | Flags any single vendor above 40% of category spend as a dependency risk |
| 4. Hand off | Passes flagged categories to the Procurement Savings Agent for renegotiation, or the Risk Assessment Agent for supplier risk scoring |
