Code Review

This pull request adds urllib3 to the requirements.txt file to address a vulnerability. The reviewer recommends pinning the dependency to an exact version (==2.2.2) instead of using >= to ensure reproducible builds and prevent unexpected deployment failures.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

In application dependency files (like requirements.txt for Google App Engine), it is best practice to pin dependencies to exact versions using == instead of >=. This ensures reproducible builds and prevents unexpected deployment failures if a newer version of the library is released with breaking changes.
