second-opinionlisted

Send a draft, analysis, plan, or decision to the reviewer for an independent cross-family read before the active primary commits. Use when the user says "second opinion," "what does the reviewer think," "sanity check this," "cross-check," or "have the reviewer review," and before any consequential, hard-to-reverse choice — architecture commitment, clinical protocol, contract clause, pricing change, finalized strategy, hiring decision, launch go/no-go. Also offer this proactively when the user is about to ship, sign, or send something the same draft will not easily walk back, especially when the active primary has reasoned its way to a confident answer without outside friction.

## Unified runtime invocation Resolve the **plugin root** from this loaded file: `SKILL.md` is at `<plugin-root>/skills/<skill-name>/SKILL.md`. Invoke only `python3 "<plugin-root>/coordinator.py"` and send one bounded JSON request on stdin. Before constructing it, read the **Coordinator request schema** in `<plugin-root>/README.md`; never invent fields or route/action pairs. The public coordinator re-observes the active host/model, captures artifact provenance, excludes same-family routes, and verifies the co-packaged native manifest. It runs standalone from the installed plugin. Never discover a provider executable or reconstruct a raw command. Frontmatter `tier` is a routing recommendation, never a coordinator request field. For a review, cross-check, tiebreaker, or fallback over an authored artifact, capture its exact UTF-8 content and observed author model in the optional `artifact` object even when governance is false; never paste it into the prompt as a provenance substitute. # Second opinion — independent cross-family read A second opinion is an explicitly *adversarial* read on a piece of the active primary's reasoning by an eligible model from a distinct family. Its job is to expose disagreements and blind spots, not to ratify. ## When to use Use this skill when one or more of the following are true: - **The user explicitly asks for it** — "second opinion," "what does the reviewer think," "sanity-check this," "cross-check," "have the reviewer review." - **A comm
