外部 LLM CLI (v2.0 では OpenAI Codex) を Reviewer として subprocess invoke する skill。 git diff + plan.md + rubric を組み立てて codex exec --json --output-schema に渡し、 structured JSON output を verify.json に merge する。 timeout / non-zero exit / 認証失敗時は自動で dual-claude にfallback (graceful degrade)。

From the source SKILL.md

v2.0 で導入された external reviewer 起動 skill。 OpenAI Codex CLI を subprocess として呼び、 schema 強制 JSON を受け取って verifier の verify.json に merge する。 v2.1+ で Gemini CLI 等の他 vendor を同じ pattern で増設できるよう、「subprocess + JSON schema + fallback」を抽象化している。
