Examples

• /google-ecosystem:gemini-second-opinion Is this database schema normalized correctly?
• /google-ecosystem:gemini-second-opinion Review my approach to error handling in this module
• /google-ecosystem:gemini-second-opinion Should I use microservices or monolith for this project?
• /google-ecosystem:gemini-second-opinion Validate my security assessment

Execution

Build Review Prompt

topic="${ARGUMENTS:-the current context}"

prompt="REVIEW MODE (read-only): Provide an independent analysis.

TOPIC: $topic

Please provide:

2. **Potential Issues**: What concerns or risks do you see?

3. **Alternative Approaches**: What other options should be considered?

4. **Recommendations**: What would you suggest?

5. **Confidence Level**: How confident are you in this assessment? (High/Medium/Low)

Be direct and specific. If you disagree with an apparent approach, say so clearly.

DO NOT modify any files. This is analysis only."

Execute Query

result=$(gemini "$prompt" --output-format json)

Parse Response

response=$(echo "$result" | jq -r '.response // "No response received"')
tokens=$(echo "$result" | jq '.stats.models | to_entries | map(.value.tokens.total) | add // 0')
model=$(echo "$result" | jq -r '.stats.models | keys[0] // "unknown"')

# Check for errors
error=$(echo "$result" | jq -r '.error.message // empty')
if [ -n "$error" ]; then
  echo "Error: $error"
  exit 1
fi

Use Cases

Validate a Plan

Before executing a significant change, get Gemini's take:

/google-ecosystem:gemini-second-opinion I'm planning to refactor auth to use JWT instead of sessions. Good idea?

Cross-Check Analysis

After Claude provides analysis, validate:

/google-ecosystem:gemini-second-opinion Claude identified 3 security issues in auth.ts. Are there others?

Architecture Decision

Get input on technical choices:

/google-ecosystem:gemini-second-opinion Should this use GraphQL or REST?

Code Review Supplement

Add another perspective to code reviews:

/google-ecosystem:gemini-second-opinion Is this error handling approach robust?

Notes

• Uses "REVIEW MODE" prefix to ensure read-only analysis
• Provides structured output with assessment, issues, alternatives
• Includes confidence level for transparency
• Two AI perspectives catch more issues than one
