codex-first skillB
codex-first is agent-read markdown (skill) from steipete/agent-scripts: Claude Code work routing: delegate implementation, fixing, exploratory subagents, rebasing, and PR merging/landing to GPT-6 Astra through Codex CLI while the parent specifies, decides, reviews, and verifies. Apply the native-Claude model gate. Codex-backed autoreview is always allowed and preferred..
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 steipete/agent-scripts/codex-first@git:20260905.2e2773bmdr add steipete/agent-scripts/codex-first@sha256:b27a805565930c0dPin 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.
