Error Messages/Logs

Steps to Reproduce

Steps to reproduce

1. Open Claude Code with Max plan
2. Run a command using /prd-creator skill (e.g. read /app/dashboard and generate its PRD)
3. Error appears immediately, even with minimal scope commands
4. Switching from Opus 4.6 to Sonnet 4.6 did not resolve
5. Opening a new conversation did not resolve
6. Reducing command scope (from full codebase to single folder) did not resolve

Expected behavior

Requests should be processed normally since usage counters show available quota.

Actual behavior

All requests are blocked with rate limit errors regardless of usage level shown in Settings → Usage.

Additional context

The issue persists across model switches (Opus → Sonnet) and new conversations. Usage dashboard confirms limits are not exhausted. This appears to be a mismatch between the rate limit enforcement logic and the actual usage counters displayed to the user.

Screenshots of usage counters showing 0% available attached.
