Use the research-summarizer Skill.

Synthesize the supplied research notes for our ecommerce product team. Extract each source's question, method, sample, numerical findings and limitations; compare agreements and conflicts, retain traceable citations and quotations, and recommend the decisions the evidence can support plus the most useful next research step.

The attached business materials are:
- inputs/a.txt
- inputs/b.txt
- inputs/brief.txt

Deliver a complete result.md report that the operations team can read, plus any finished files needed for this task. Keep supporting calculations and evidence with the deliverables. Write the report in English; use the requested target language for customer-facing copy. The business datasets are fictional examples unless the brief explicitly names a live public website.
