codex-playbook skillA

codex-playbook is agent-read markdown (skill) from gaia-research/gaia-skill-heaven: Drive the Codex CLI as a benchmark target or dispatched worker. Use when running codex probes, comparing codex postures, building codex-zero, or handing work to a codex agent. Covers non-interactive exec, sandbox and config isolation, model and reasoning-effort selection, and the per-session skills toggle..

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 gaia-research/gaia-skill-heaven/codex-playbook@git:20260810.ae24947
Exact content
mdr add gaia-research/gaia-skill-heaven/codex-playbook@sha256:2b6becb9fd2f695d

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.
