[Bug] Anthropic API Error: Opus 5.5 Safeguards Incorrectly Flagging Non-Cybersecurity Content

Bug Description

I’m just trying to protect my own work and discussing with the model how I can protect my project. However, I keep getting the following API error:

Opus 5.5's safeguards flagged this session (https://www.anthropic.com/legal/aup). You may be seeing this for the first time on an Opus model: Opus 5.5 is more capable and has stronger safeguards as a result, which can sometimes flag non-cybersecurity work. We're improving these safeguards to reduce the amount of incorrectly flagged messages. Claude Code can't respond to your last message with Opus 5.5.
