[Bug] Anthropic API Error: Sonnet 5.5 Safeguards Incorrectly Flagging Non-Cybersecurity Work

Bug Description
API Error: Sonnet 5.5's safeguards flagged this session (https://www.anthropic.com/legal/aup). You may be seeing this for the first time on a Sonnet model: Sonnet 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 Sonnet 5.5.
