Delegate a well-scoped implementation to OpenAI Codex through its Claude Code companion plugin in an isolated git worktree, then independently verify it with tests and adversarial review before a user-approved merge. Use when the user wants Codex to implement a bounded change, wants a second model's implementation attempt, or wants a safe Codex implementation-and-review workflow.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Delegate implementation to Codex, then verify Use the Codex companion's `task --write` runtime. It gives the implementation session `workspace-write`; it is not a permission to modify the main checkout. Create the worktree yourself, keep the task inside it, and retain merge authority. The review gate for work implemented here is a **non-GPT reviewer, at every risk level** — the cross-family rule ([`docs/methodology.md`](../../docs/methodology.md) §1) has no LOW-risk exemption. A `codex-adversarial-review` pass over Codex's own work is a fresh context, **not** model diversity: legitimate as an *additional* supplement, never as the gate. HIGH-risk work takes two reviewers from two non-GPT families. ## Before the first run of a session Read **[`../codex-adversarial-review/references/codex-runtime.md`](../codex-adversarial-review/references/codex-runtime.md)**. It holds the family-level mechanics shared by both codex roles — companion resolution, the `--background` launcher-output trap, `status` lying about liveness, report recovery from session rollouts, what the sandboxes can and cannot do, and the model/effort plumbing. This file assumes them and covers …

How to install
mdr add aarontzeng/dev-lead/codex-implement@sha256:ad5ecbd35ecaa8e0The line at the top of this page pins the label git:20260925.1a5468f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
