What's Wrong?

Claude Sonnet 4.6 Autocompact Buffer steals a significant portion of the context window on startup.
Sonnet 4.6 is intentionally hobbled, the window should have never been 200k tokens for a working code tool.
I've spent more time coding structures to make working in 200k possible than actual project coding.
The default window on Sonnet should be 500k, up charging for a 1M window is a money grab.
As much as I prefer coding with Sonnet over Opus, it just doesn't make sense to pay for Anthropic subscriptions if it's going to be a constant hassle. I'll just use a different coding harness for a different $20/month frontier model and eliminate my worries about tokens and usage windows.

What Should Happen?

Anthropic should stop stealing from customers.
