install-codex-agents skillA
install-codex-agents is agent-read markdown (skill) from heapy/kortex: Install this plugin's Kotlin review agents into Codex, which cannot load agents from a plugin..
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 heapy/kortex/install-codex-agents@git:20260828.b388895mdr add heapy/kortex/install-codex-agents@sha256:3f60023d01e61813Pin 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.
