codex is agent-read markdown (skill) from garrytan/gstack: OpenAI Codex CLI wrapper — three modes. (gstack).
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.
mdr add garrytan/gstack/codex@v1.0.0mdr add garrytan/gstack/codex@sha256:9db0da2e30b54038Pin 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.
