We need to setup custom logger for whole repo, not just for only one particular script

🛠️ Refactor suggestion

Well-structured logging format with room for improvement

The custom format provides comprehensive logging with timestamps, colors, and structured output. However, there are a few improvements needed:

  1. Follow JavaScript naming conventions by using camelCase:
-format.printf(({ level, timestamp, message, stack, tool_name, url }) => {
+format.printf(({ level, timestamp, message, stack, toolName, url }) => {
   let logMessage = `${level} at ${timestamp}`;
   logMessage += `\n${message}`;
-  if (tool_name) {
-    logMessage += `\n   Tool: ${tool_name}`;
+  if (toolName) {
+    logMessage += `\n   Tool: ${toolName}`;
   }
  1. Remove unnecessary empty line at line 9
