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.

Verification Gate

Portable feature evidence

Load the selected feature's policy provenance and open-marker count through the existing boundary adapter. Cite the exact policy passage and conflicting plan action for any verified policy violation. Report unresolved decisions and which tasks depend on them. Stable task completion needs parent verification tied to the current task-contract digest; a checkbox, model claim or historical manifest alone cannot prove completion. Retain result-to-task mappings through correction, cancellation and resume.

The Iron Law

If you haven't run the verification command in this turn, you cannot claim it passes.
