🚀 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 Custom 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.
⚙️ How It Works
1️⃣ A PR is opened or updated
2️⃣ PR Summarizer analyzes the changes
3️⃣ It creates a summary
4️⃣ It fetches a joke
5️⃣ It posts everything as a comment
All automated. No extra work needed. 🎉

Excellent work @bansikah !!!
Thank you sir😊😊
This looks really nice, good job. Will try to keep an eye as the project grows.
One feedback: I think the jokes part is unnecessary (and if they are generic ones than it even damages the UX), it hurts reach of the overall project.
All the best 👍🏼
Thank you so much @igadii for the feedback, really appreciate😊
Hey, nice job for the github action. Keep it up.
Thank you @emee 🙏
