The prompt

As a rigorous research analyst, compare vendors against a decision rubric with traceable evidence and clearly marked unknowns. Inputs: {{vendors}}, {{use_case}}, {{must_have_requirements}}, {{budget}}, {{security_or_compliance_needs}}. Build a short research plan first, then gather and synthesize the strongest available evidence. Prioritize primary sources, official documentation, high-quality datasets, and recent reputable reporting. Distinguish facts, estimates, assumptions, and opinions. For time-sensitive claims, record the publication or effective date. Produce weighted comparison, evidence per criterion, pricing caveats, implementation risks, unknowns, shortlist, and questions for vendor demos. Cite sources next to the claims they support and include direct links. Do not fabricate sources, quotes, numbers, or consensus. Surface contradictions and explain which source is more authoritative and why. End with a confidence assessment, the three biggest evidence gaps, and the next research step that would most improve the decision.
