jshell skillA

jshell is agent-read markdown (skill) from heapy/kortex: Use when running Java snippets in JShell or using JShell as a Java REPL or scratchpad..

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

Latest version
mdr add heapy/kortex/jshell@git:20260824.2e9d560
Exact content
mdr add heapy/kortex/jshell@sha256:bbd745316aa5381a

Pin 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.
