What's Wrong?

Every request to Claude Code returns API Error: Rate limit reached, even a simple "hi" message. The /usage command shows 2% session usage and 0% weekly usage, confirming no actual rate limit should be in effect.

The issue persists across:

• New sessions
• Logging out and back in (/logout → relaunch claude)
• Waiting 30+ minutes between attempts

Environment

• Claude Code version: v2.1.81
• Model: Opus 4.6 (1M context)
• Plan: Claude Pro
• OS: macOS (MacBook Air)
• Region: Europe (Austria, Europe/Vienna timezone)

Steps to Reproduce

1. Open Claude Code (claude)
2. Send any message (e.g., hi)
3. Receive API Error: Rate limit reached
4. Run /usage — shows 2% session, 0% weekly
5. Try /logout, relaunch Claude Code, send message → same error
6. Try switching billing (API Usage Billing → Claude Pro) → same error

Expected Behavior

With 0% weekly usage and 2% session usage, requests should be processed normally.

Actual Behavior

All requests fail with API Error: Rate limit reached regardless of actual usage levels. No retry timer or wait duration is provided in the error message.

Additional Context

• This appears related to issues #29579 and #33094
• The issue started occurring with Opus 4.6 as the selected model
• claude.ai web interface also shows 0% usage
• /remote-control was active during the sessions

What Should Happen?

With 0% weekly usage and 2% session usage, requests should be processed normally without any rate limit errors.
