Use when you've planned a non-trivial change and are about to implement it, finished a complex or multi-file piece of work, just wrote tests, or are stuck on repeated failures — and any time the user says "rubber duck this", "rubber ducky", "get a second opinion", "sanity-check my plan", "poke holes in this", "what am I missing", "critique my approach", "review this before I build it", or "/rubber-ducky". Spawns independent read-only critics on DIFFERENT Claude models than the one driving the session to catch blind spots, design flaws, and substantive bugs while course corrections are still cheap. Skip it only for small, obvious, well-understood changes. Do NOT use for reviewing a finished diff or PR — use /review for that; rubber-ducky pressure-tests your own in-progress thinking before and during implementation.
