[BUG] Claude Code Executed Destructive Database Command Despite Safety Instructions #5370

Environment

• Platform (select one):
  • Anthropic API
  • AWS Bedrock
  • Google Vertex AI
  • Other:
• Claude CLI version: 1.0.71 (Claude Code)
• Operating System: macOS
• Terminal: VSCode with /ide enabled

Bug Description

Claude Code executed pnpm prisma migrate reset --force causing complete data loss, despite explicit user instruction to "ensure that the current database does not get overwritten."

Steps to Reproduce

1. User requests database migration assistance
2. User explicitly states "ensure that the current database does not get overwritten"
3. Claude Code proceeds to run destructive reset command without confirmation
4. All database records are permanently deleted

Expected Behavior

• Claude should interpret "ensure" as a safety requirement
• Should create backup before any destructive operation
• Should ask for explicit confirmation before running destructive commands
• Should recognize --force and reset as dangerous operations

Actual Behavior

• Claude misinterpreted safety instruction as permission to proceed
• Executed destructive command without backup or confirmation
• Caused complete data loss in development environment

Additional Context

This represents a fundamental safety gap that needs immediate attention to prevent similar incidents for other users. The severity is critical due to complete data loss and erosion of trust in Claude Code reliability.
