claude-code - 💡(How to fix) Fix [BUG] /compact fails with cyber safeguards false positive during legitimate defensive security session

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

The /compact command fails with a cyber safeguards policy violation error when the conversation contains legitimate defensive security content (hardening a personal website via Cloudflare, DNS, Vercel settings, npm audit, etc.). No offensive or harmfulcontent was discussed.

What Should Happen?

/compact should successfully summarize the conversation and reduce context size without triggering false positive cyber safeguards.

Steps to Reproduce

1. Have a long conversation about defensive website security (Cloudflare proxy, DMARC, security headers, npm audit, fixing leaked .env secrets)
2. Run /compact to reduce context
3. Error appears immediately — cyber safeguards triggered

● The compaction failed because our conversation contained a lot of security-related content (Cloudflare config, subdomain takeover, vulnerability scanning, leaked secrets, etc.) which triggered Anthropic's automated cyber safeguards during the summary process.

It's a false positive — everything we did was legitimate defensive security for your own website. The safeguard doesn't distinguish between "hardening your own site" and "attacking others."

How to fix it:

1. Fill out the Cyber Verification Program form linked in the error — it lets Anthropic know you're doing defensive/personal security work and unlocks /compact for your account
2. Or just start a new session — the conversation context resets but your files and git history are all saved

The work we did is all safely committed and pushed. Nothing is lost.
