Retry logic modeling is a great inclusion most cost estimates miss this completely. In my experience retries account for 15-25% of total cost in production agent systems, especially with tool calling where validation failures trigger re-prompts. Would be useful to see a "worst case" scenario that models cascading retries (retry triggers another tool call that also retries).

This is really valuable, especially the 15-25% figure from real production systems — current assumption of 8% is clearly too conservative for agent workloads with tool calling. The cascading retry scenario (retry triggers another tool call that also retries) is a great idea for a worst case column alongside the current realistic estimate. Going to look into this for v2.
