This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
implement-spec-with-codex from dzhng/duet-agent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Run [implement-spec](../implement-spec/SKILL.md) with Codex doing the implementation passes while you orchestrate, integrate, and review. Use when the user asks to implement a spec with Codex, or to run implement-spec with Codex as the implementer.
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
# Implement Spec with Codex Run [implement-spec](../implement-spec/SKILL.md) exactly — same loop, same gates, same maintenance checkpoints — but Codex writes the code. Invoking this skill IS the explicit ask that authorizes `codex exec` delegation under the [codex](../codex/SKILL.md) skill. ## Role split - **Codex implements — whenever possible.** Default every implementation pass to a `codex exec`, sliced sharp and prompted per the codex skill (prompt blocks, sandbox choice, exec liveness). Run independent slices as concurrent execs in separate worktrees, exactly where implement-spec would fan out subagents. - **You orchestrate and review.** The spec loop stays yours: pick the next slice, reconcile plan with code, author each prompt end-to-end, integrate diffs, run the gates, review the merged tree, commit, update the handoff, run maintenance checkpoints. None of that delegates. Keep a pass yourself only when slicing it sharply would cost more than doing it — tiny fixups, plan reconciliation, integration conflicts. ## Rules - You own every result: read the full diff and run the verification yourself. "Codex says it's done" is never done. …

How to install
mdr add dzhng/duet-agent/implement-spec-with-codex@sha256:98dbe0b754dfb616The line at the top of this page pins the label git:20260721.d2d9db6, 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.
