Nice work on the observability side. We built something complementary - NadirClaw routes requests across multiple providers based on cost/performance tradeoffs. Your Prism setup shows which departments are spending, then a routing layer like NadirClaw can cut that spend 40-70% by sending simple prompts to cheaper models when appropriate. The two would work well together - tracking + optimization.
