Code Review

This pull request adds the zipp dependency to requirements.txt to address a vulnerability. The reviewer recommends pinning zipp to an exact version (==3.19.1) rather than using >= to ensure build reproducibility and prevent unexpected breaking changes.

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.

[gemini-code-assist]

For application deployments, it is highly recommended to pin all dependencies to exact versions to ensure build reproducibility and prevent unexpected updates from introducing breaking changes. Please pin zipp to ==3.19.1 instead of >=3.19.1.

zipp==3.19.1 # not directly required, pinned by Snyk to avoid a vulnerability
