Creating a Code Review

Manual Review Requests

Create a review for your changes:

  1. Open the Source Control view
  2. Stage the changes you want to review
  3. Right-click and select "Create Review Request"
  4. Add reviewers, title, and description
  5. Click "Submit for Review"

Pre-Commit Reviews

Review code before committing:

  1. Stage your changes
  2. Click "Review Changes" in the Source Control view
  3. Use the diff view to self-review
  4. Add inline comments or request AI analysis
  5. Revise as needed before committing

Pull Request Integration

Integrate with GitHub, GitLab, or other platforms:

  1. Create a pull request through your platform's interface
  2. Open the PR in ThinkCode using the Source Control view
  3. Navigate through files and add comments directly
  4. Push additional changes in response to feedback
  5. Mark PR as ready for merge when approved

Reviewing Code

Access and navigate code review requests:

  1. Open the Code Review panel from the Activity Bar
  2. Filter reviews by status, author, or repository
  3. Select a review to open the diff view
  4. Navigate between files using the file tree
  5. Toggle between unified and split diff views

Adding Comments and Feedback

Provide effective feedback:

  1. Click the line number in the diff view to add a comment
  2. Use markdown formatting for clear communication
  3. Reference documentation or best practices
  4. Link to related issues or pull requests
  5. Add reactions to existing comments

Example comment with markdown:

Consider using a more descriptive variable name here:
 
```typescript
// Instead of:
const x = calculateValue();
 
// Consider:
const totalAmount = calculateValue();

This improves readability for future developers.

}

Automated Code Quality Checks

Enforce standards consistently:

  1. Configure quality checks in Settings > Code Review > Quality Checks
  2. Specify minimum thresholds for metrics like:
    • Test coverage
    • Complexity
    • Duplication percentage
    • Documentation coverage
  3. Set rules to block reviews that fail critical checks
  4. View quality check results in the Review Summary

Learning from Reviews

Improve your coding through AI insights:

  1. After receiving review feedback, select problematic code
  2. Click "AI: Explain Issues" to understand the underlying principles
  3. Use "AI: Suggest Learning Resources" for targeted improvement
  4. Save insights to your personal knowledge base

Best Practices for Effective Reviews

Review Preparation

Prepare thoroughly before review:

  1. Self-Review First: Review your own code before requesting feedback
  2. Include Context: Provide background information and requirements
  3. Clear Scope: Specify what aspects need particular attention
  4. Reasonable Size: Keep reviews under 400 lines of code when possible
  5. Add Tests: Include relevant tests with your changes

Giving Effective Feedback

Provide constructive and actionable feedback:

  1. Focus on Code, Not Coder: Address the code, not the person
  2. Be Specific: Point to exact issues rather than general criticisms
  3. Explain Why: Provide reasoning behind suggestions
  4. Suggest Alternatives: Offer concrete improvements
  5. Prioritize Issues: Distinguish between critical issues and style preferences

Responding to Feedback

Handle received feedback professionally:

  1. Consider Objectively: Evaluate feedback on its merits
  2. Ask Questions: Seek clarification on unclear feedback
  3. Explain Decisions: Provide context for why certain approaches were taken
  4. Express Gratitude: Acknowledge the reviewer's effort
  5. Learn Continuously: Use feedback as a learning opportunity

Advanced Review Techniques

Code Review Templates

Standardize reviews with templates:

  1. Navigate to Settings > Code Review > Templates
  2. Create templates for different review types
  3. Include standard questions and focus areas
  4. Apply templates when starting a review
  5. Customize for specific projects or teams

Example template for a security-focused review:

## Security Review Template
 
### Authentication & Authorization
- [ ] Proper authentication mechanisms implemented
- [ ] Authorization checks in place
- [ ] Sensitive operations properly protected
 
### Data Validation
- [ ] Input validation implemented
- [ ] Output encoding used where appropriate
- [ ] SQL/NoSQL injection prevented
 
### Additional Security Concerns
- [ ] Secrets management follows best practices
- [ ] Error handling doesn't reveal sensitive information
- [ ] Security headers configured correctly

Multi-Stage Reviews

Implement phased review processes:

  1. Configure multi-stage review workflows
  2. Define required approvals for each stage
  3. Set up automatic transitions between stages
  4. Track progress through the review dashboard
  5. Generate metrics on review efficiency

Contextual Reviews

Provide better context for complex changes:
