What's Wrong?

User prompts add ~2000 tokens to the context.

This might be the case with all tool call responses as well, potentially adding thousands of tokens to say "0 results found" or similar responses.

What Should Happen?

User prompts and tool responses should NOT add ~2000 tokens to the context.
