second-opinion

Offer-only validation pipeline for a verdict or recommendation. Use when the user asks to validate, verify, fact-check, or get a second opinion on a claim or recommendation — "are you sure", "double-check this", "second opinion". Batches fact-checking against sources, adds scoped advisor personas for the angles that need judgment, then re-emits the response grouped into verified, flagged, and conflict, with a mandatory validation delta. Requires a subagent-spawning tool; without one it must decline rather than simulate.

PORTABILITY: the claim-extraction, grouping, and delta discipline port to any harness. The pipeline itself needs a subagent-spawning tool; where none exists, Step 0 requires this skill to decline and fall back to search-based verification rather than fabricate a result. This skill is harness-agnostic in judgment and gated only on that one capability.
