Pull Requests (PR) are crucial in software development as they enable collaborative coding. They provide a structured process for code review, ensuring quality and catching potential issues before merging into the main codebase. PRs also promote documentation, knowledge sharing, and facilitate communication among team members, contributing to a more organised and efficient development workflow.

Every developer will agree that pull requests are the lifeblood of collaborative software development. However, reviewing them can be tedious, time-consuming, and prone to human error. That's where AI-powered PR assistants like  CodiumAI PR Agent and GitHub Copilot for PR come in. In this article, you will learn how to make your pull request magical using AI-powered tools like CoduimAI PR Agent. 

### Prerequsites

To optimise your experience with this article, it's advisable to have a foundational understanding of pull requests and version control.

## Overview of GitHub copilot


GitHub Copilot is an AI-powered tool that acts as your AI pair programmer, suggesting code completions and turning prompts into suggestions to complete your code. Imagine having an experienced developer sitting beside you, constantly offering helpful hints and snippets to speed up your coding workflow. That's essentially what Copilot does.

Here's how it can help developers:

**Write code faster:** Copilot can suggest common coding patterns, functions, and even entire lines of code based on the context of your project. This can save you time typing boilerplate code and let you focus on the more creative aspects of development.

**Write more consistent code:** Copilot learns from the vast amount of code available on GitHub and suggests code that is idiomatic to the language you're using. This can help you avoid making common mistakes and ensure your code is consistent with the coding style of your project.

**Write more concise code:** Copilot can suggest shorter and more efficient ways to write the code you're working on. This can help you improve the readability and maintainability of your code.

**Explore new ideas:** If you're stuck on a problem, Copilot can suggest different approaches you might not have thought of. This can help you spark new ideas and get unstuck.
Here's an example of how Copilot works:

Let's say you're writing a Python script to scrape data from a website. You might start by typing something like:

```
import requests
response = requests.get("https://www.example.com")
```



At this point, Copilot might suggest something like:

```
# Parse the HTML response
soup = BeautifulSoup(response.content, "lxml")

# Find all elements with the class "data-item"
data_items = soup.find_all("div", class_="data-item")

# Extract the data from each element
for item in data_items:
    title = item.find("h2").text
    price = item.find("span", class_="price").text
```

As you can see, Copilot can save you a lot of time and effort by suggesting the code you need to write next.
 
But its capabilities extend beyond just speeding up your coding sessions. Enter the Copilot PR feature, currently in an exclusive beta, promising to revolutionise how you handle pull requests.

Imagine this:

- **Effortless PR summaries:** Struggling to articulate the essence of your code changes? Copilot analyses your pull request and crafts a concise, informative summary, highlighting key changes and potential areas for review. No more writer's block!

- **Code improvement suggestions:** Did you just refactor a function? Copilot scans your changes and proposes alternative implementations, potentially using more efficient algorithms or idiomatic language constructs. It's like having a seasoned reviewer at your fingertips.


- **Context-aware comments:** Leave helpful comments throughout your code, but with a twist. Copilot suggests relevant comments based on the changes you make, saving you time and ensuring reviewers understand your thought process.

### Limitations of GitHub copilot PR feature

**Specific Focus:** As of now, the PR feature primarily focuses on generating summaries and suggesting code improvements. While exciting, it's not a one-stop shop for handling every aspect of your pull requests.

**Waiting List:** Currently, access to the Copilot PR feature is limited to a selected group of beta testers. If you're not already in, you'll need to join the waiting list and patiently await your turn.

**Early Stages:** Remember, it's still in beta, meaning you might encounter bugs, glitches, and occasional hiccups.

**Price Tag:** Copilot has a subscription fee. While the exact cost for the PR feature might not be officially revealed yet, expect it to add to the existing Copilot subscription.

If you're seeking a seasoned PR agent to optimise your workflow without constraints, let me introduce you to the **CodiumAI PR Agent.** In the subsequent sections of this article, we'll delve deeper into the CodiumAI PR solution and explore how it can significantly simplify your life as a developer
