## How the agent team uses proposal & invoice management integrations

When the Builder agent reads a prompt that involves proposal & invoice management work, it assembles specialists from the team — Researcher, Writer, Designer, Engineer, Distributor — and routes proposal & invoice management tool calls through the **Distributor specialist**. The Researcher pulls context, the Writer or Designer produces the output, the Distributor pushes the result into the user's proposal & invoice management tool of choice. The Verifier checks every call and self-heals on rate limits, schema drift, or auth refresh.

The Builder picks the right proposal & invoice management integration per workflow based on what the user has connected — no manual mapping required.
