Setting CORS Access-Control-Allow-Origin to '*' allows any origin to access the DevTools, which could pose security risks. Consider restricting this to specific origins or implementing a more secure CORS policy for production environments.

The conditional clone of depot_tools could lead to inconsistent builds if the directory exists but contains outdated or corrupted files. Consider always cloning fresh or implementing a more robust check for depot_tools validity.
