Bug Description
Subject: False Positive Triggered by Opus 5 and Opus 4.8 Safeguards in Legitimate Android Reverse Engineering Development

Description:
I am encountering persistent false positive triggers from the safety safeguards of both Opus 5 and Opus 4.8 while using Claude Code for Android module development. My work involves security analysis and module development for Android applications using tools like adb, frida, apktool, etc. All of these activities are legitimate, defensive security research.

Specific Issues:

After sending a request, Opus 5's safety filter is triggered with a [cyber] tag.

The system automatically downgrades to Opus 4.8, but Opus 4.8 also blocks the request.

Ultimately, I receive an API Error and cannot continue my work.

Multiple attempts to rephrase the prompt still trigger the filter.

Nature of My Work:

My work is legitimate and defensive Android security research

I am performing modular development and reverse engineering analysis of Android applications

These operations are purely for security auditing and educational purposes

No malicious attacks or illegal activities are involved

Expected Improvements:

Improve the [cyber] classifier for Opus 5 and Opus 4.8 to differentiate legitimate security research from malicious attacks.

Provide more transparent trigger reasons to help users adjust prompts to avoid false positives.

If there is a whitelist mechanism, I would like to apply for inclusion to reduce interruptions to legitimate development work.

Looking forward to your response. Thank you!
