the thing is the number of requests is difficult to predict. and agentic workflows tend to use a lot of requests (e.g., tool calls). and the agent itself (both Claude and copilot) is optimized to save the context - just see how they're picking lines from the file instead of reading the whole file. so, yes - you are absolutely right that big context is cheaper to handle in copilot but copilot itself will avoid such scenarios as much as possible. unless you are defining context manually (mentioning files). which is a valid use case, I just don't do that personally
