What's Wrong?

Claude Code fails on Pro plan with standard agentic tasks (reading 5 files) with error:

API Error: Usage credits required for 1M context · turn on usage credits at claude.ai/settings/usage, or use --model to switch to standard context

My Pro weekly limit is only 24% used. The selected model is Sonnet 4.6. Usage credits balance is €0.00 — I never needed them before for this workflow. Enabling usage credits opens a payment screen. This workflow worked previously without credits.

What Should Happen?

Agentic tasks reading local files should work within Pro plan limits without requiring usage credits.

Additional Information

I am a Pro plan subscriber using Claude Code desktop app on Windows 11. This workflow (reading multiple markdown files and organizing them) worked previously without any credits. After a Windows reset and Claude Code reinstall, the app now requires 1M context credits for the same tasks. Weekly limit shows only 24% used. Enabling usage credits requires purchasing — this was not required before.
