Cross Fact-Checking (Claude + Gemini)

Perform independent fact-checking on the target document using three different AIs: Claude Opus, Gemini Flash, and Gemini Pro, discuss the issues, and output a consensus report.

Prerequisites

Gemini CLI (
```
gemini
```
) is already installed
Flash is the default model (no need to specify
```
-m
```
)
Pro is specified with
```
-m gemini-3-pro-preview
```

Steps

Step 1: Identify the Target

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

Step 2: Independent Checks by Three Parties

Opus (Self)

Read through the target document and perform fact-checking
Verify primary sources via WebSearch

Gemini Flash

Execute the following in Bash:

bash

cat <file-path> | gemini -p "Please fact-check the following document. Verify the accuracy of technical facts, numerical consistency, internal contradictions, and the correctness of code examples. Clearly state the basis for each point, and classify them as 'Required Fix / Recommended Improvement / Accurate' in your report."

Gemini Pro

Execute the following in Bash:

bash

cat <file-path> | gemini -m gemini-3-pro-preview -p "Please fact-check the following document. Verify the accuracy of technical facts, numerical consistency, internal contradictions, and the correctness of code examples. Clearly state the basis for each point, and classify them as 'Required Fix / Recommended Improvement / Accurate' in your report."

Step 3: Compare Results & Extract Issues

Cross-reference the results from the three parties
Unanimous agreement: Adopt as is
Two agree + one disagrees: Extract as an issue
All disagree: Extract as a critical issue
Detected by only one party: Opus performs additional verification

Step 4: Discuss Issues

For each issue:

Opus collects additional verification information via WebSearch
Re-ask each Gemini with the verification information attached:

bash

echo "<Issue content and additional verification information>" | gemini -p "Please state your opinion on the following issue based on the additional information."
echo "<Issue content and additional verification information>" | gemini -m gemini-3-pro-preview -p "Please state your opinion on the following issue based on the additional information."

Synthesize all responses and make a final decision

Step 5: Output Consensus Report

Notes

Opus must always verify Gemini's results (Gemini may have false positives)
Resolve issues based on evidence, not by majority vote
Re-ask each Gemini individually for each issue
