[Model Behavior] Safeguards falsely triggering on simple, benign messages and interrupting sessions
Preflight Checklist
- [x] I have searched existing issues for similar behavior reports
- [x] This report does NOT contain sensitive information (API keys, passwords, etc.)
Type of Behavior Issue
Claude modified files I didn't ask it to modify
What You Asked Claude to Do
I was having an ordinary conversation (including short, simple messages with no harmful, security, or sensitive content) when the safety system flagged my message.
What Claude Actually Did
Instead of responding normally, the session was paused with a message saying my message was flagged by the safeguards. I was given the option to switch to a different model or edit the prompt and retry. This happens frequently, even on very simple messages that contain nothing harmful.
The result is that normal, routine work gets interrupted repeatedly and I have to either switch models or rewrite messages that were perfectly benign to begin with.
Expected Behavior
Ordinary, non-harmful messages should not be flagged. Simple, routine messages should get a normal response without pausing the session. The safeguards should be far less likely to produce false positives on benign content so that everyday use isn't disrupted.

Can You Reproduce This?
Yes, every time with the same prompt
Steps to Reproduce
- Start a normal session
- Send an ordinary, simple message (no harmful, security, or sensitive content)
- The message is flagged by the safeguards and the session is paused, offering to switch models or edit and retry

Additional Context
The safeguards appear to be over-broad and produce frequent false positives on benign messages, which interrupts normal work. It happens even with short, simple messages.
