What problem does it solve? Multiple articles agreeing on a claim often trace back to a single press release, creating the illusion of independent confirmation. This Skill establishes whether a load-bearing claim is actually supported by two or more genuinely independent sources, preventing manufactured consensus from reaching executive summaries and recommendations. ## Core Features & Use Cases - Four independence tests: Checks each source pair for different originator, first-hand root document, publication event, and incentive structure, collapsing any cluster that fails a test into its single highest-graded member. - Structured verdict output: Emits a JSON report listing every source with its Admiralty grade, every collapsed source with the test it failed, the surviving independent count, and a verdict of corroborated, single-source, contested, or uncorroborated. - Use Case: Before publishing a brief stating a company closed a $3.5 billion Series E, gather five articles asserting it, walk each to its first-hand root, collapse the four that trace to the company's own announcement, and report the claim as single-source rather than corroborated. ## Quick Start Use triangulate-sources to check whether these articles citing the same valuation figure are genuinely independent or all quoting one press release.
