Page Summary
-
You can customize Gemini Code Assist's code review by adding a
styleguide.mdfile in the.gemini/folder of your repository. -
The enterprise version allows managing style guides and configurations for multiple repositories via the Google Cloud console.
-
Gemini Code Assist's standard code review focuses on correctness, efficiency, maintainability, security, and miscellaneous topics when a custom style guide is not provided.
-
A
config.yamlfile can be used to enable or disable various features and specify files to ignore using glob patterns. -
When both repository-specific and Google Cloud console configurations exist, the repository's
config.yamloverrides console settings, whilestyleguide.mdfiles are combined.
You can modify Gemini Code Assist on GitHub
behavior by adding a config.yaml
file to a .gemini/
folder located in the
root of your repository. The config.yaml
file contains various configurable
features that you can enable or disable, including specifying files to ignore using glob patterns
.
Gemini Code Assist also supports adding a styleguide.md
file
to the .gemini/
folder, which instructs Gemini Code Assist with
some specific rules that you want it to follow when performing a code review.

Manage configurations across multiple repositories
Some aspects of Gemini Code Assist on GitHub can be managed across multiple repositories:
-
If you have the consumer version, you can toggle certain settings for all repositories that are associated with an account.
-
If you have the enterprise version, you can toggle certain settings for multiple repositories grouped by a Developer Connect connection. When you do, you manage their collective settings through the Google Cloud console.
If a repository is managed as part of a group but also has its own config.yaml
, the repository's config.yaml
settings override the group
settings.
For specific setting behavior and exceptions, review the config.yaml schema .
The following steps show how to control one set of configurations across multiple repositories. These steps assume you have previously set up Gemini Code Assist on GitHub .
