codex-auto-model-router

Recommend and execute an efficient Astra, Sol, or Luna route with GPT-5.6 compatibility with low-through-max reasoning for Codex project work. Prefer bounded direct tool concurrency, but automatically create or reuse a model-specific leaf agent when route-fit benefit clearly exceeds startup and aggregation overhead; no extra user permission is required. Use for code changes, tests, reviews, routed implementation, model recommendations, usage queries, retuning, and requests to disable, exit, restore, or check this Skill for the current project. Use the legacy strict state machine only when the user explicitly requests strict ledger auditing. Never auto-select Ultra or create a new top-level Codex task.
