fact-check

Fact-check (Claude multi-model)

Perform independent fact-checking on the target document using multiple models within Claude, and cross-check the results.

Procedure

Step 1: Identify the target

• Identify the target document from the conversation context
• If the target is ambiguous, confirm with Daiki

Step 2: Check by Opus (itself)

• Read through the target document and fact-check it from the following perspectives:
  • Accuracy of technical facts (versions, APIs, configuration values, limit values, etc.)
  • Consistency of numerical values (calculation results, totals, etc.)
  • Internal contradictions (inconsistencies between sections)
  • Accuracy of code examples
• Verify primary sources with WebSearch and clearly state the evidence
• Classify the results as "Correct / Needs correction / Improvement recommended"

Step 3: Independent check by a Sonnet subagent

• With the Task tool, Sonnet (model: "sonnet") Launch a subagent
• Pass only the path of the target document to the subagent, and do not share Opus's results (to ensure independence)
• Example prompt:

以下のドキュメントをファクトチェックしてください。
技術的事実の正確性、数値の整合性、内部矛盾、コード例の正確性を検証し、
「正確 / 要修正 / 改善推奨」に分類して報告してください。
WebSearch で一次ソースを確認し、根拠を明記すること。

Step 4: Comparison and discussion of results

• Cross-check the results from both
• Matching findings → Adopt as is
• Findings from only one side → Opus performs additional verification and makes a judgment
• Findings where opinions are divided → Perform additional verification with WebSearch and reach a conclusion based on evidence

Step 5: Output of the consensus report

• Report to Daiki in the following format:
