Cross-Model Review
Use a fresh reviewer to challenge an artifact against the original request. A different model family can add useful diversity, but agreement is not proof. Preserve the user's configured model and effort unless the user explicitly requests a change. Skill guidance does not override the task's scope, existing authorization, or host permissions.
Choose the Review Surface
| Situation | Route |
|---|---|
| Claude author, Codex available | Scoped codex review, or codex exec for custom questions |
| Codex author, Claude available | claude -p with a bounded brief and restricted tool access |
| Pi with the xreview extension | Use its installed /xreview interface after checking its scope semantics |
| Native reviewer with a different model family | Use the exposed delegation tool when authorized; inspect its actual schema |
| Different family unavailable | Fresh-context review can still help; disclose that it provides context independence only |
Run the chosen CLI's --version and relevant --help before relying on flags. Tool names, wait limits, permissions, and model availability belong to the current host. An external CLI is still delegation; it does not bypass a host prohibition.
For CLI details and a copyable launcher, read references/cli-flags.md. Use references/prompts.md for the requested review mode. Load references/failure-recovery.md only when a launch fails or stalls.
