Codex model routing policy for anti-hall work. Use when selecting models for planning, implementation, review, debate, or mechanical execution in Codex.
gpt-5.4-mini (default) — gpt-5.6-luna available when 5.6-era capability/cutoff matters (not the default) — gpt-5.3-codex-spark is a distinct, faster/less-capable model, ChatGPT Pro only, not an effort setting of the flagship
low
Rules:
Debate roles always use gpt-5.6-sol.
Do not use mini models for security-sensitive validation or launch go/no-go decisions.
Do not run every subtask on gpt-5.6-sol; distribute by task shape.
If a model is unavailable or rate-limited, record the limitation and choose the nearest safe fallback. Do not silently downgrade debate below gpt-5.6-sol.
Claude-side mapping (when coordinating with Claude agents)
When this skill coordinates with anti-hall deadly-loop or ship-it, the Claude-side tier token sonnet resolves to Sonnet 5 (claude-sonnet-5). Claude-side role assignments:
Main coordinator, planning top-level, deep debug: model:"opus" = latest Claude Opus
Cross-model rule: if Codex implements, Claude (Sonnet 5 or Opus) reviews. If Sonnet 5 implements, Codex or Opus reviews. No agent reviews its own implementation.
