call-codex skillA
call-codex is agent-read markdown (skill) from heapy/kortex: Use when the codex CLI should be driven from the agent — as a reviewer giving a second, independent opinion ("ask codex", "call codex", "codex review", "get a second opinion", "challenge this finding"), or as an executor doing a scoped task in the repository ("have codex do this", "delegate this to codex", "let codex implement it"). Covers which flags codex actually understands, how much access each mode needs, how to write a prompt that produces verdicts instead of agreement, and the integratio.
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/call-codex@git:20260811.b5f04d9mdr add heapy/kortex/call-codex@sha256:81f075a0478d7210Pin 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.
