Host: Codex CLI — This skill was designed for Claude Code and adapted for Codex. Cross-reference commands use installed skill names in Codex rather than /octo:* slash commands. Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it. For host tool equivalents, see skills/blocks/codex-host-adapter.md.

Architecture review

Load skills/blocks/engineering-method-selection.md from the installed plugin and apply only the methods relevant to this task. Preserve this entry point's execution contract and output format. Read referenced skills as instructions; do not invoke the current command recursively or add provider calls from a seat.

Run this method on the current host. A routine architecture review makes zero additional provider dispatches. --peer-review, an explicit independent-review request, or an existing risk policy may add one bounded external reviewer through Octopus routing. Report incomplete independent coverage if that reviewer cannot read the source or does not return a grounded contribution.
