Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant enhancement to the Looker toolset by adding a new project_git_branch tool. This tool empowers users to programmatically manage Git branches within their LookML projects, enabling operations such as listing, retrieving, creating, switching, and deleting branches. This addition streamlines development workflows by providing direct control over project versioning within the Looker environment.

Highlights

Code Review

This pull request introduces a new project_git_branch tool for Looker, enabling git branch manipulation for LookML projects. The implementation is mostly solid, with corresponding changes in documentation, prebuilt configurations, and integration tests. However, there are a few areas for improvement. The core logic in the new tool lacks unit tests, which is a significant gap. There's also a documentation inaccuracy for one of the tool's parameters and some redundant code that goes against project conventions. Addressing these points will improve the correctness and maintainability of the new tool.
