Considerations

  • Gemini Code Assist on GitHub does not generate summaries or code suggestions for any files located within the .github/workflows directory. This exclusion helps prevent the introduction of potentially insecure configurations to the repository.

  • The enterprise version uses a Developer Connect connection to connect your GitHub repositories to Google Cloud.

    • This Developer Connect connection is always created in the region us-east1.

    • This Developer Connect connection must be created using the Code Assist Source Code Management section found in Gemini Code Assist Agents & Tools. For instructions, see Set up Gemini Code Assist on GitHub.
