???? PR Summarizer: Making Code Reviews Fun and Efficient

???? A Developer’s Struggle with PR Reviews

It was another late night. Coffee in one hand, I clicked on yet another pull request with 37 file changes. ????

"Alright, let’s go through this."

Five minutes in, I was already scrolling endlessly through modified files, trying to figure out:

• What actually changed?
• Why were these changes made?
• Do I really have to read every file to understand?

By the time I got halfway, my focus was gone, and I hadn’t even left a single review comment yet.

And then it hit me:

Why do we still manually analyze PRs in 2025? Can’t we automate this?

That’s when I decided to build PR Summarizer—a tool that does the hard work for you and even makes code reviews fun! ????

???? Meet PR Summarizer

PR Summarizer is a GitHub Action written in Rust ???? that:

✅ Detects modified, added, and deleted files

???? Generates a clean summary of PR changes

???? Posts a helpful comment on the PR

???? Includes a random programming joke (because why not?)

???? The Problem: Code Reviews Are Overwhelming

PRs can be a nightmare, especially when they:

• Contain too many files
• Lack a clear description
• Have vague commit messages

This wastes time, slows down development, and makes reviewing a chore. ????

???? The Solution?

???? PR Summarizer automates PR analysis so you can:

✔ Quickly understand changes at a glance

✔ Save time reviewing PRs

✔ Enjoy a fun programming joke along the way ????

???? Example Output

Imagine opening a PR and instantly seeing this comment:

???? PR Summary

???? Changes Overview

✨ Implemented user authentication

✅ Added JWT token handling

✅ Created registration API

???? Updated API docs

???? Affected Files

???? [+] src/auth/jwt.rs

???? [M] src/routes/users.rs

???? [M] README.md

???? Code Humor

"Why do programmers prefer dark mode? Because light attracts bugs!" ????

Now, reviewers immediately understand the changes without digging through commits.
