detekt is a static code analysis tool specifically designed for Kotlin projects

​
Files

detekt will run on files with the following extensions:
  • .kt
  • .kts

​
Configuration

detekt uses a YAML style configuration file. detekt supports the following config files:
  • User-defined config file set at reviews.tools.detekt.config_file in your project’s .coderabbit.yaml file or setting the “Review → Tools → detekt → Config File” field in CodeRabbit’s settings page.
If no user-defined config file is found, CodeRabbit will generate a detekt-config.yaml file based on the selected profile.

​
When we skip detekt

CodeRabbit will skip running detekt when:
  • No Kotlin files are found in the pull request.
  • detekt is already running in GitHub workflows.

​
Profile behavior

CodeRabbit generates different detekt configurations based on the review profile:
  • Chill Mode: Uses a focused configuration with fewer rules enabled.
  • Assertive Mode: Uses a more comprehensive configuration with additional rules enabled.
If you provide your own config file, it will be used instead of the generated one.
