⚠️ Critical: Background/Non-Interactive Mode Warning

NEVER use --approval-mode default in background or non-interactive shells (like Claude Code tool calls). It will hang indefinitely waiting for approval prompts that cannot be provided.

For automated/background reviews:

• ✅ Use --approval-mode yolo for fully automated execution
• ✅ OR wrap with timeout: timeout 300 gemini ...
• ❌ NEVER use --approval-mode default without interactive terminal
