3

Follow implementation guidance

The agent provides:
  • A structured plan for implementing the solution
  • Code suggestions with detailed explanations
  • Testing recommendations
  • Best practice guidance

​
Step 6: Review and Submit Your Contribution

1

Review the implementation

Before submission, the agent will:
  • Run relevant tests to verify your changes
  • Generate new unit tests when appropriate

Real-World Example Walkthrough

Here’s what a typical contribution session looks like: 
YOU: I'd like to contribute to this repository

OSS CONTRIBUTOR: I'll help you contribute to this project. 
Let me check for open issues...

Found 15 open issues that might be good candidates. Here are the top 3:
1. #1423: "Fix init template to use latest React Native version" [good-first-issue]
2. #1408: "Update documentation for monorepo setup" [documentation]
3. #1399: "Add unit test for config validation" [testing, help-wanted]

Which issue would you like to work on?

YOU: The first one sounds good

OSS CONTRIBUTOR: Great choice! I'll help you implement a fix for issue #1423.

First, I'll create a new branch called "fix/init-template-version-1423"...
[Branch created successfully]

Let me examine the issue and related code...
[Agent analyzes template files and version references]

I've identified the problem in 'template.js' where the React Native version is hardcoded to '0.68.0'. 
Let me suggest a fix...

[Agent provides code suggestions with explanations]

Would you like me to implement this change?

YOU: Yes, please go ahead

[Agent implements the fix]

I've updated the template.js file. Now let's add a test to verify the fix works correctly...

[Agent generates unit test]

Let's run the tests to make sure everything works...

[Tests pass successfully]

Great! The fix is working as expected. Would you like me to prepare a pull request?

YOU: Yes, please

[Agent creates PR with detailed description]

Pull request #1435 has been created! Here's the link: [PR URL]

Best Practices for Successful Contributions

​
Choosing the Right Issues

Start Small

Begin with issues labeled “good first issue” or simple documentation fixes to familiarize yourself with the project’s workflow.

Match Your Skills

Select issues that align with your current skill level while still providing learning opportunities.

Check Activity

Choose issues that are actively discussed and have recent maintainer engagement to ensure they’re still relevant.

Read Guidelines

Always review the project’s CONTRIBUTING.md file and any issue templates before starting work.

​
Quality Contribution Tips

Communication is key:
  • Comment on the issue before starting work to avoid duplicate efforts
  • Ask questions if requirements are unclear
  • Keep maintainers updated on your progress
Code quality matters:
  • Follow the project’s coding standards and style guides
  • Include appropriate tests for your changes
  • Write clear, descriptive commit messages
  • Keep changes focused and minimal
Documentation helps:
  • Update relevant documentation when making functional changes
  • Include clear descriptions in your pull requests
  • Provide context for your implementation decisions

​
Common Issues and Solutions

Solution: Try these approaches:
  • Look for repositories with more active issue management
  • Check if the project uses different labels (like “beginner-friendly” instead of “good first issue”)
  • Ask the agent to search for issues without specific labels
  • Consider contributing documentation improvements or bug reports
Solution: Verify your setup:
  • Ensure GitHub CLI is properly installed: gh --version
  • Re-authenticate: gh auth logout then gh auth login
  • Check your GitHub Personal Access Token has appropriate permissions
  • Verify the MCP integration is properly configured
Solution: Work with the agent to debug:
  • Ask the agent to analyze the test failures
  • Review the project’s testing documentation
  • Ensure all dependencies are properly installed
  • Check if the project has specific testing requirements
Solution: Learn and improve:
  • Carefully read the maintainer’s feedback
  • Ask the agent to help address the requested changes
  • Use this as a learning opportunity for future contributions
  • Consider starting with smaller, simpler issues
