⏺ Fable 5's safeguards flagged this message. Our intentionally broad safeguards allow us to deliver more capabilities faster, but can sometimes flag legitimate coding, cybersecurity, and biology tasks. Switched to Opus 5. Send feedback with /feedback or learn more
⎿ Tip: You can configure model switch behavior in /config
