When to choose Claude Opus 4.8
1
Long-document synthesis
Extract decisions, disagreements, evidence, and action items from a large source set.
Prompt starter
Analyze these documents as one evidence set. Separate confirmed facts, open questions, and contradictions. Produce an executive summary plus a source-linked action table.
2
Repository-scale code review
Trace behavior across files, identify failure paths, and propose a scoped patch plan.
Prompt starter
Review the attached code for [goal]. Trace the request end to end, list findings by severity with file evidence, then propose the smallest safe patch and focused tests.
3
Evidence-led research plan
Turn an open question into hypotheses, evidence needs, evaluation criteria, and a final report shape.
Prompt starter
Design a research plan for [question]. List competing hypotheses, the evidence needed to test each one, source-quality criteria, stopping rules, and the final report outline.
