What's Wrong?

Environment

• Platform: Claude Code CLI
• Claude CLI version: 2.1.30 (Claude Code)
• Operating System: Linux
• Terminal: Konsole
• Plan: Claude Pro
• Timezone: Europe/Paris

Bug Description

Claude Code completely blocks all usage when session limit reaches 77%, despite /usage showing 23% remaining quota. The error message states "You've hit your limit • resets 2am (Europe/Paris)" but the usage dashboard clearly shows capacity still available.

Impact

This effectively reduces the usable session quota to 77% of limit

The rate limiting enforcement system appears to be blocking users before they reach their actual quota limit, or there's a desync between the usage tracking display and the rate limiting enforcement mechanism?

What Should Happen?

Claude Code should allow usage up to 100% of the session limit. If /usage shows 77% used, I should be able to continue working until reaching 100%.

Error Messages/Logs

- `/usage` command shows: **77% used** with reset at 2am
- Claude Code displays: **"You've hit your limit • resets 2am (Europe/Paris)"**
- All prompts are completely blocked despite 20% quota remaining
- Weekly limit shows only 9% used (plenty of capacity)

## Supporting Evidence

### `/usage` Output

### `/stats` Output (showing minimal total usage)

Total tokens: 37.9k
Sessions: 4
Active days: 1/2

### Web Interface Comparison
Web interface (claude.ai Settings > Usage) shows 77% session usage, which aligns with CLI showing 77% - but both should still allow continued usage.

## Additional Context

- This occurs consistently - not a one-time glitch
- The `/usage` display does not update to 100% even after waiting several minutes
- Total token usage (37.9k) is very modest, suggesting the block is premature
- Weekly quota is barely used (9%), so this is specifically a session limit calculation issue
- The blocking persists until the scheduled reset time

Steps to Reproduce

1. Use Claude Code normally during a session
2. Monitor usage with /usage command
3. Observe that blocking occurs at approximately 77% instead of 100%
4. Attempt to send any prompt - all requests are rejected
5. Run /usage again - still shows 77%, not 100%
