What this error means

You've hit your session limit · resets 3:45pm / You've hit your weekly limit · resets Mon 12:00am is a Claude Code failure pattern reported for developers trying to understand and fix claude code usage quota exhaustion; buy more credits or manage rolling limits. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

Official Claude Code docs document three types of usage-limit errors (session limit, weekly limit, Opus limit). Users see explicit reset timestamps but confusion between usage vs context limits is rampant. Many hit limits unexpectedly due to session-resume token generation bug (GitHub #38029: 652K tokens generated without user prompts). Commercially critical — blocks paying Pro ($20/mo), Max ($100/mo), Enterprise users mid-workflow. Anthropic credit overhaul coming June 15, 2026 adds urgency.

Quick fixes

  1. Confirm the exact error signature matches You've hit your session limit · resets 3:45pm / You've hit your weekly limit · resets Mon 12:00am.
  2. Check the Claude Code account, local tool state, and provider configuration involved in the failing workflow.
  3. Reduce request pressure, check quota or plan limits, and retry with backoff instead of immediate repeated requests.

Platform/tool-specific checks

  • Verify the command, editor, extension, or API client that produced the error.
  • Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
  • Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

  1. Capture the exact error message and the command, editor action, or request that triggered it.
  2. Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
  3. Review the source evidence below and compare it with your environment.
  4. Apply one change at a time and rerun the smallest failing action.
  5. Keep the working fix documented for the team or deployment environment.

How to prevent it

  • Keep provider/tool configuration documented.
  • Record non-secret diagnostics such as tool version, provider name, model name, and command path.
  • Add a lightweight check before CI or production workflows depend on the tool.
