Default model: gemini-3-pro-preview
Parse model from prompt if specified (e.g., "using flash, review...")
If given a file path, note it for piping to gemini. Optionally gather relevant codebase context from CLAUDE.md.
Use @ syntax for files, or stdin piping:
# Using @ syntax (preferred for files)
gemini --sandbox -o text -m gemini-3-pro-preview \
"You are a senior software architect reviewing a plan/specification.
Review for:
1. Architectural soundness
2. Missing requirements or edge cases
3. Implementation risks
4. Scalability concerns
5. Unclear specifications
6. Security considerations
Provide specific, actionable feedback." @plans/my-feature.md
# Or pipe via stdin
cat plans/my-feature.md | gemini --sandbox -o text -m gemini-3-pro-preview \
"Review this plan for architectural issues and risks"
# Review multiple related plans
gemini --sandbox -o text -m gemini-3-pro-preview \
"Review these plans for consistency" @plans/feature-a.md @plans/feature-b.md
Or use the wrapper script:
scripts/gemini-review.sh --plan plans/my-feature.md
Important: Use @ for files/folders, stdin for generated content (diffs). Never use heredocs or variable assignment.
