What problem does it solve? Uncited research answers cannot be verified: a claim without a URL and a date cannot be re-checked, and undated links go stale silently. This Skill enforces a research discipline where every factual statement traces to a named source read on a named date. ## Core Features & Use Cases - Two-pass verification: Runs two independent research passes with different queries, then cross-checks claims — confirmed items become findings, single-pass items are labeled single-sourced, and contradictions are surfaced rather than averaged away. - Mandatory citation discipline: Every claim carries a source URL and retrieval date; anything unsourced is labeled unsourced opinion, never blended into findings. - Provenance honesty: Community posts are labeled community-claim and treated as leads, never as primary-source evidence; paywalled or credential-gated sources are recorded as unreachable. - Use Case: A teammate asks you to verify a vendor's changelog claim. You run two passes, confirm it against the vendor's own page with today's date, flag a contradicting community post, and deliver a dated markdown brief ending with the decision the finding supports. ## Quick Start Research whether the vendor's API supports batch endpoints and give me a cited brief with a URL and retrieval date on every claim.
