codex
Router for using GPT-5.5 via the OpenAI Codex CLI as a subagent. Four modes — advisor (adversarial pressure-test of the user's position; replaces jstack-challenge), review (independent code/plan review), implement (clear-spec bulk implementation), investigate (research/diagnosis/data analysis). Use when the user says "/codex", "/jstack-challenge", "challenge me", "pressure test this", "second opinion", "spawn an advisor", "stress test my thinking", "play devil's advocate", "have codex review/implement/investigate X", "send this to codex", or "run this on gpt-5.5". Global CLAUDE.md decides WHEN to route work to codex; this skill is HOW to brief it.
