devbox review --component=chat

# Review with custom port
devbox review --component=authentication --port=9090

# Review without starting the web server
devbox review --component=content --start-server=false

3. View Review Reports

After running a review, open your browser and navigate to:

http://localhost:8080

Configuration

Configuration File

The code review feature creates a configuration file at ~/.devbox/.code-review/config.yaml:

# OpenAI Code Review Configuration
openai:
  api_key: ""  # Set your OpenAI API key here or use environment variable
  model: "gpt-4"  # Model to use for code review
  max_tokens: 4000  # Maximum tokens for review response
  temperature: 0.1  # Lower temperature for more focused reviews

review:

    - python
    - javascript
    - typescript
    - java
    - go
    - rust
  file_extensions:
    - .py
    - .js
    - .ts
    - .jsx
    - .tsx

    - "*.min.css"
    - "dist/"
    - "build/"
    - "target/"
    - "vendor/"
  max_file_size: 100000  # Maximum file size in bytes to review
  max_files_per_review: 50  # Maximum number of files to review at once

output:
  format: "html"  # html, markdown, json
  include_suggestions: true
  include_severity: true
  include_line_numbers: true
  include_code_snippets: true

Customizing Review Settings

You can modify the configuration file to:

• Change the OpenAI model (e.g., gpt-3.5-turbo for faster, cheaper reviews)
• Adjust the number of tokens used
• Add or remove supported file types
• Modify exclusion patterns
• Change output format preferences

Review Process

1. File Detection

The system automatically detects changed files in your component:

• Staged changes (git diff --cached)
• Unstaged changes (git diff)
• Filters by supported file extensions
• Respects exclusion patterns

2. Content Preparation

• Reads file contents
• Prepares context for OpenAI
• Limits file size and count for optimal performance

3. AI Review

• Sends code to OpenAI GPT-4
• Uses specialized prompt for code review
• Receives comprehensive analysis

4. Report Generation

• Parses AI response
• Generates structured review data
• Creates beautiful HTML report
• Starts local web server

Best Practices

Before Submitting PRs

1. Run Local Tests: Ensure your code passes all tests
2. Perform Code Review: Use devbox review to get AI feedback
3. Address Issues: Fix critical and warning issues
4. Review Suggestions: Consider implementing improvement suggestions
5. Submit PR: Only after addressing important issues

Optimizing Review Quality

1. Keep Changes Focused: Smaller, focused changes get better reviews
2. Include Context: Make sure related files are included
3. Use Descriptive Commits: Clear commit messages help with context
4. Review Regularly: Don't wait until the end to review

Cost Management

1. Monitor Usage: Keep track of API token usage
2. Use Appropriate Models: Consider gpt-3.5-turbo for routine reviews
3. Limit File Count: Focus on the most important files
4. Batch Reviews: Review multiple related changes together

Troubleshooting

Common Issues

API Key Not Found

Error: OpenAI API key not found

Solution: Set the OPENAI_API_KEY environment variable or use --api-key parameter

API Connectivity Issues

Error: OpenAI API connectivity test failed

Solution: Check your internet connection and API key validity

No Changed Files

Warning: No changed files found for review

Solution: Make sure you have staged or unstaged changes in your component

Server Port Already in Use

Error: Port 8080 is already in use

Solution: Use a different port with --port parameter

Performance Tips

1. Limit File Size: Large files take longer to review and cost more
2. Use Appropriate Model: gpt-3.5-turbo is faster and cheaper than gpt-4
3. Review Incrementally: Review changes as you make them, not all at once
4. Exclude Generated Files: Add generated files to exclusion patterns
