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.

Bounded prototype

Use a prototype to answer one named question, not to start implementation by a different name.

Contract

Agree on the question, hypothesis, deadline, artifact path, and success signal before writing. Record the source revision. Store artifacts through scripts/plan-storage.sh, outside the installed plugin cache.
