## What kortex does, in the publisher's words

Kotlin- and JVM-focused agent skills for JetBrains Kotlin Toolchain, Kotlin/JVM, Multiplatform, JShell, and related development workflows.

- Kotlin Toolchain declarative project setup with module.yaml, project.yaml, templates, dependencies, plugins, and the kotlin CLI.
- Version-aware guidance for Kotlin Toolchain v0.12.x, with a retained v0.11.x snapshot and a 0.11 -> 0.12 migration guide.
- Kotlin/JVM, Android, iOS, Kotlin Multiplatform, Kotlin/JS, Kotlin/Wasm, Kotlin/Native, server-side apps, testing, publishing, migration, and toolchain provisioning.
- Modern Kotlin language features (2.0 to 2.4.x, including 2.4.10 and the 2.4.20-Beta1 EAP) with experimental compiler flags and per-version references back to Kotlin 1.4.
- Ktor 3.5.x server and client development: routing, requests/responses, plugins, serialization, authentication, sessions, WebSockets, SSE, engines, testing, deployment, and multiplatform client work.
- Java snippets and scratchpad work with JShell.
