Second Opinion · guyaga bundle Get an independent second opinion from the Codex CLI (OpenAI GPT-5.x) on a plan, prompt, design, code change, or any piece of work — then run a structured debate/relay between Claude and Codex until they converge, and synthesize a joint recommendation. Codex shares Claude's skills (via ~/.agents/skills) so it can ground its critique in the same playbooks (e.g. seedance-2-prompt-engineer). Use when the user says "second opinion", "ask codex", "what does codex think", "run it by codex", "debate this with codex", "sanity check with gpt", or "/second-opinion".
