🔍 PR Review

Todo List:

• Read the changed file to understand the modification
• Check if tests exist for this change
• Verify the fix follows project patterns
• Provide review feedback

Change Analysis:
The PR changes line 12 from:

process.env.LOG_LEVEL = 'silent';

to:

process.env.LOG_LEVEL = process.env.LOG_LEVEL || 'fatal';

This allows users to specify their own LOG_LEVEL while maintaining 'fatal' as the default.

❌ CRITICAL: No tests → Fix: Add tests for LOG_LEVEL environment variable handling in examples/standalone-cli-chat.ts

💡 SUGGESTION: Comment inconsistency → Consider: Line 8 usage example shows LOG_LEVEL=fatal but the default was 'silent', now 'fatal'. Update comment to match or explain the difference.

💡 SUGGESTION: 'silent' vs 'fatal' → Consider: The change from 'silent' to 'fatal' as default may affect existing users who expect completely silent output. Document this breaking change.

Overall: The fix correctly respects user LOG_LEVEL but lacks tests and has potential breaking change implications.
