Install programming for Codex

Installs for the current user

codex plugin marketplace add alexei-led/cc-thingz
codex plugin marketplace upgrade alexei-led-cc-thingz
codex plugin add programming@alexei-led-cc-thingz

writing-java-kotlinskills/writing-java-kotlin/SKILL.md

Idiomatic modern Java and Kotlin JVM development. Use when writing `.java`, `.kt`, or `.kts` code; changing Gradle or Maven builds; or working on Spring, Micronaut, Quarkus, Ktor, Android JVM modules, JUnit, Mockito, Kotest, ktlint, detekt, or JVM CLI/services. Emphasizes JDK toolchains, null-safety, fast focused Gradle/Maven feedback, deterministic formatting, and minimal dependencies. NOT for JavaScript/TypeScript, C#/.NET, Python, shell scripts, or infra-only work.
