Complete deep research report workflow with Claude: research framework design (design question structure first) → source processing one by one (don't paste all at once) → perspective conflict mapping (find disagreements between sources) → argument construction (your perspective + Claude testing and strengthening) → report generation and refinement (2-3 rounds to usable quality). Core principle: you handle judgment and perspective; Claude handles information organization and structure.
Design rationale for "process sources one by one with cumulative summary updates": if you paste all sources at once, Claude must hold massive amounts of information in Context simultaneously, and middle sections get diluted (Lost in the Middle problem). Processing sources individually with cumulative updates keeps the most important information (core arguments, perspective differences) at the end of Context (highest attention position), maintaining Claude's attention on key information.
Why argument construction must be you-led: the perspectives in a research report reflect your judgment on the topic. Readers read it to understand your analysis and stance, not Claude's. Claude can help identify weaknesses in arguments, find stronger supporting evidence, and optimize argument structure — but "I believe" must be your belief; otherwise the report loses its meaning as your analysis.
This workflow is most suitable for: regularly producing opinionated analysis reports (monthly, quarterly, industry analysis); synthesizing multiple sometimes-contradictory sources (academic research, media coverage, primary interviews); reports whose audience depends on your judgment for decisions (your perspective matters, not just information aggregation). Not suitable for: simple summaries needed, no time for multi-round iteration, or the task is information aggregation rather than perspective analysis.
