writing-java-kotlin skillA
writing-java-kotlin is agent-read markdown (skill) from alexei-led/cc-thingz: Idiomatic modern Java and Kotlin JVM development. Use when writing `.java`,.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add alexei-led/cc-thingz/writing-java-kotlin@git:20260716.29b4d22mdr add alexei-led/cc-thingz/writing-java-kotlin@sha256:40913e8073133d76Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
