Detekt - State of the Union
summary
detekt is a community‑driven static analyzer for Kotlin that already ships 220 rules, including syntactic checks like magic number, semantic checks like unnecessary not‑null operator and double mutability for collections, and configurable forbidden method call lists. It runs as a CLI, Gradle plugin (producing many per‑variant tasks), IntelliJ plugin, outputs SARIF, and wraps KtLint integration for autocorrection. Type‑resolved rules use a binding context and currently require classpaths; work is underway to replace double compilation with a compiler plugin.
