Why is Zed making two API calls per for each submitted message at the start of a new conversation?

[mooreryan]

I have connected my Anthropic key to Zed assistant. I was monitoring the logs on Anthropic and I see two API calls per submitted assistant message when I start a new conversation. I would like to know why it is doing that. Is there a way I see what API calls Zed is actually making?

Looking at the API logs, the second call's input tokens are approximately the amount of the first call's input tokens + output tokens...so maybe it is has to do with the Anthropic prompt caching? Additional messages submitted in the same conversation appear not to trigger multiple calls per message, however.
