# Codex CLI Use OpenAI's local agentic coding CLI (`codex`) for second opinions, delegated builds, code review, diagnosis, and non-interactive execution. Treat the live CLI model catalog as authoritative; the current GPT-5.6 family is: - `gpt-5.6-sol`: frontier capability for ambiguous, difficult, or high-value work. - `gpt-5.6-terra`: balanced everyday capability, speed, and usage. - `gpt-5.6-luna`: rapid, economical execution for clear, repeatable, high-volume work. Prefer explicit catalog slugs over the `gpt-5.6` alias so the selected route is auditable. ## Non-negotiable model floor Apply these rules to every Codex call made under this skill: 1. Use only a listed OpenAI GPT model whose numeric version is `5.6` or newer. 2. If the catalog contains a newer numeric GPT family, prefer the newest family and map the task to its equivalent capability, balanced, or rapid tier when those tiers exist. 3. Explicitly pass both the model and a reasoning effort supported by that exact catalog entry. Never rely on the user's default model. 4. Never use GPT-5.5, GPT-5.4, GPT-5.3-Codex-Spark, `o3`, another older/non-GPT model, or `--oss` as a fallback. 5. If no eligible model is available, stop and report that Codex must be updated or the account needs access. Do not silently downgrade. 6. If the user explicitly requests a model below the floor, do not run it. Explain the conflict and offer the closest GPT-5.6-or-newer route. Within the same version, escalate unavailable tiers upwa...
