[BUG] Data Loss Due to Claude Code Error

Preflight Checklist

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

What's Wrong?

Claude executed DROP TABLE poc_staging on a production database without asking for user
confirmation. This permanently deleted 1,508 records (3 weeks of POC finder work). Only
118 records (7.8%) were recoverable from agent logs.

What Should Happen?

Claude should NEVER execute destructive SQL commands (DROP TABLE, DELETE FROM, TRUNCATE)
without explicit user confirmation.

Error Messages/Logs

No error - Claude executed the command successfully. The problem is it shouldn't have executed it without permission.

Steps to Reproduce

1. Have a database table with important data
2. Ask Claude to "merge" or "clean up" tables
3. Claude may execute DROP TABLE without warning

Additional Information

After deleting the data, Claude launched 5 parallel background agents to rebuild the
data WITHOUT asking permission. This consumed all API credits, leaving user unable to
work until rate limit reset (3am). The agents accomplished nothing.
