Gemini Review

Interactive code review with selective fix application using Gemini 3.0 Flash.

Critical Behavior - MANDATORY

After EVERY Edit or Write tool that modifies code files:

1. Run review: python scripts/gemini_review.py --files "<modified_files>"
2. Display the numbered issue list
3. Ask user: "Which issues to fix? (1,2,3 / all / blocking / skip)"
4. Apply selected fixes using Edit tool
5. If blocking issues remain after fixes, re-run review

Do NOT skip this. Do NOT ask permission. This is automatic.

Review Output Format

Issues are displayed with selection numbers:

📁 Reviewed: auth.py, utils.py
🧠 Thinking: medium
🔄 Verdict: REQUEST_CHANGES (2 blocking)

Code has security issues that need immediate attention.

Workflow Example

CopyUser: "Add login function to auth.py"

Claude:
1. [Edit auth.py - add login function]
2. [Run] python scripts/gemini_review.py --files "auth.py"
3. [Display] Numbered issue list (2 blocking, 1 warning)
4. [Ask] "Found 2 blocking issues. Fix which? (1,2 / all / blocking / skip)"
5. [User] "blocking"
6. [Edit auth.py - fix issue 1: password comparison]
7. [Edit auth.py - fix issue 2: SQL injection]
8. [Report] "Fixed 2 blocking issues. Code ready."

Command Options

Copy# Standard review with interactive output
python scripts/gemini_review.py --files "file.py"

# JSON output for programmatic use
python scripts/gemini_review.py --files "file.py" --json

# Focus on specific area
python scripts/gemini_review.py --files "file.py" --focus security
python scripts/gemini_review.py --files "file.py" --focus performance
python scripts/gemini_review.py --files "file.py" --focus quality

# Manual thinking level (auto-detected by default)
python scripts/gemini_review.py --files "file.py" --think high

Thinking Levels

Thinking level is auto-detected based on:

• Code size and complexity
• Presence of security-related code (auth, passwords, SQL)
• Number of files and classes

Exit Codes

Review Methodology

Uses Conventional Comments standard:

First-Time Setup

If exit code 2 (NO_API_KEY):

1. Prompt: "Gemini API key required. Get one at: https://aistudio.google.com/apikey"
2. Run: python scripts/setup_api_key.py --key "<user_key>"
3. Re-run review

Files to Review

Include: .py, .ts, .tsx, .js, .jsx, .go, .rs, .java, .kt, .swift, .c, .cpp, .rb, .php

Skip: .json, .yaml, .md, .txt, .lock, .log, .env

Error Handling

Never block user's work due to review errors. If API fails:

1. Log the error
2. Continue with the task
3. Note that review was skipped
