Diff Review via Gemini
Have Gemini review git changes for a second perspective on code quality.
Quick Start
Save diff to project root, have Gemini review, then clean up:
bash
git diff --cached > gemini-review.diff
gemini "Review the code changes at gemini-review.diff for issues. Do not make any changes. Respond with feedback only." --allowed-tools read_file,codebase_investigator,glob,search_file_content,list_directory,write_todos -o text 2>&1
rm gemini-review.diff
Patterns
Staged changes:
bash
git diff --cached > gemini-review.diff
gemini "Review gemini-review.diff for:
1. Bugs or logic errors
2. Security vulnerabilities
3. Style inconsistencies
4. Missing error handling
Do not make any changes. Respond with feedback only." --allowed-tools read_file,codebase_investigator,glob,search_file_content,list_directory,write_todos -o text 2>&1
rm gemini-review.diff
All uncommitted changes:
bash
git diff HEAD > gemini-review.diff
gemini "Review gemini-review.diff. Do not make any changes. Respond with feedback only." --allowed-tools read_file,codebase_investigator,glob,search_file_content,list_directory,write_todos -o text 2>&1
rm gemini-review.diff
Specific commit:
bash
git show abc123 > gemini-review.diff
gemini "Review the commit at gemini-review.diff. Do not make any changes. Respond with feedback only." --allowed-tools read_file,codebase_investigator,glob,search_file_content,list_directory,write_todos -o text 2>&1
rm gemini-review.diff
Focused Reviews
Security focus:
bash
git diff --cached > gemini-review.diff
gemini "Security review of gemini-review.diff. Check for:
- XSS vulnerabilities
- SQL/command injection
- Sensitive data exposure
- Authentication/authorization issues
Do not make any changes. Respond with feedback only." --allowed-tools read_file,codebase_investigator,glob,search_file_content,list_directory,write_todos -o text 2>&1
rm gemini-review.diff
Performance focus:
bash
git diff --cached > gemini-review.diff
gemini "Performance review of gemini-review.diff. Check for:
- Inefficient algorithms
- N+1 queries
- Memory leaks
- Blocking operations
Do not make any changes. Respond with feedback only." --allowed-tools read_file,codebase_investigator,glob,search_file_content,list_directory,write_todos -o text 2>&1
rm gemini-review.diff
With File Context
Ask Gemini to read full files for better context:
bash
git diff --cached > gemini-review.diff
gemini "Review gemini-review.diff. Also read the full files:
- src/auth/login.ts
- src/utils/validate.ts
to understand the broader context. Do not make any changes. Respond with feedback only." --allowed-tools read_file,codebase_investigator,glob,search_file_content,list_directory,write_todos -o text 2>&1
rm gemini-review.diff
Notes
- Gemini must not make any changes, provide feedback ONLY.
- Gemini respects
.gitignore- it cannot read files matching gitignore patterns - Gemini can only read files in the workspace directory (project root)
- Requires
dangerouslyDisableSandbox: truefor Bash calls - May take 1-2 minutes for thorough review
- See
references/setup.mdfor troubleshooting
