Root Cause

Claude Code repeatedly triggers "Usage Policy violation" on my legitimate AI research project. Every session is blocked because the classifier flags the project's source code and documentation files that are auto-loaded into context.

Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

Claude Code repeatedly triggers "Usage Policy violation" on my legitimate AI research project. Every session is blocked because the classifier flags the project's source code and documentation files that are auto-loaded into context.

The issue persists across new sessions, /clear, and rephrasing prompts. The project is completely unusable with Claude Code.

Already reported to [email protected] with all request IDs.

What Should Happen?

Claude Code should be able to read and edit legitimate AI research project files without triggering the AUP classifier.

Steps to Reproduce

  1. Open Claude Code in a project directory containing AI research code and documentation
  2. Send any prompt
  3. Classifier triggers on project file content loaded into context
  4. New sessions fail with the same error because the same project files are auto-loaded
