## What it is
detekt is a static code analysis tool for the Kotlin programming language that detects code smells and enforces configurable rule sets. It ships as a CLI, a first-party Gradle plugin, and an extensible rule engine with report output in HTML, Markdown, SARIF, and Checkstyle XML.

## Use cases
- lint kotlin code in a gradle project
- find code smells in my kotlin codebase
- enforce code quality rules in ci for kotlin
- generate a baseline of existing issues for a legacy kotlin project
- write custom static analysis rules for kotlin
- produce sarif reports for code scanning
- measure cyclomatic complexity of kotlin code

## When to choose
- you have a Kotlin JVM, Android, Multiplatform, JS, or Native project and want automated code quality checks
- you need configurable lint rules with baselines and suppression support
- you want CI-friendly reports in SARIF, HTML, Markdown, or Checkstyle formats

## When to avoid
- your codebase is not Kotlin (use language-specific linters like ESLint, Pylint, or Clippy)
- you need full type-aware IDE inspections only - IntelliJ's built-in inspections may suffice
- you need runtime bug detection or dynamic analysis rather than static analysis
