GitHub Copilot CLI Challenge Winner Announcement - Further Delayed

Jess Lee — Thu, 05 Mar 2026 21:03:10 +0000

Hi all,

I'm terribly sorry to share that we still need a few more days to announce the GitHub Copilot CLI Challenge winners. We received over 400 submissions and are doing our best to make the final selections.

Apologies for another disappointing update and thank you all again for participating, building, and sharing your work with the community.

Instead of setting a new announcement date, we are going to announce as soon as we've made the final decisions. Hopefully early next week!

Congrats to the Algolia Agent Studio Challenge Winners!

Jess Lee — Wed, 04 Mar 2026 18:25:32 +0000

The results are in! Thank you all for your patience.

We saw a wide range of submissions and are thrilled to announce our winners for the Algolia Agent Studio Challenge. While we wish we could recognize every submission, today we're highlighting the winners that stood out the most.

See if you made the list!

Congratulations To…

Consumer-Facing Non-Conversational Experiences

@_boweii introduced The Refusal Engine, a proactive security tool built to prevent cloud misconfigurations before they ever reach deployment. It’s a highly practical agent that works in the background.

Good morning! Good afternoon! Good Evening!

Welcome to our first DEV Weekend Challenge, a short focused challenge designed to fit into your weekend. Since submission window is tight, we've set the timing to ensure that no matter where you are in the world, you'll have the majority of your Saturday and Sunday to participate.

Let's get started!

Our Prompt

Think about the communities that are part of your life: your neighborhood, a book club, a local sports league, an open source project, or any other group that’s meaningful to you. This weekend, we want you to build something for them.

Your mandate is to build an app that serves a community you're a part of or care about. It can solve a real problem, spark a smile, or both. The best submissions will demonstrate a clear understanding of the community's needs and deliver something that genuinely makes their lives a little easier, more connected, or more fun.

Judging Criteria and Prizes

All submissions will be judged on the following:

Value Proposition: Does the app meaningfully serve the community it was built for?
Creativity: Is the concept original or is it an interesting take on a familiar problem?
Technical Execution: Is the app functional, well-built, and easy to use?
Writing Quality: Is the submission post clear and does it tell a compelling story about the project?

Three winners will each take home $300 USD, an exclusive DEV badge, and a DEV++ Membership. All participants with a valid submission will receive a completion badge.

How To Participate

Publish a post on DEV using the submission template below. Your post should give us an overview of the community you built for, what you made, and a demo of your project.

Want your agent to write better code with fewer tokens? Ask the Google AI Team about Agent Skills!

Jess Lee — Thu, 26 Feb 2026 20:03:50 +0000

Last week @stephr_wong, Kevin Hou, and Andy Zhang explored the Antigravity Editor and Agent Manager.

This week, @greggyb is back with special guests Luke Schlangen and Joe Hanley to dive into Agent Skills for Gemini CLI.

Ready for your agent to write better code with fewer tokens? The team will explore Agent Skills like the recently released Agent Skills for Firebase with the help of Gemini CLI. They'll test just how far these skills can take us.

Here's what's on deck:

Exploring Agent Skills and how they improve code generation
Testing the newly released Agent Skills for Firebase
Pushing the limits of what Agent Skills can do with Gemini CLI

Join the "Built with Google Gemini: Writing Challenge" Presented by Major League Hacking (MLH). Win a Raspberry Pi AI Kit!

Jess Lee — Wed, 25 Feb 2026 17:41:43 +0000

Last week, we announced that DEV has joined Major League Hacking. To kick things off, we're launching a writing challenge about a topic both communities are already familiar with: Google Gemini.

Running through March 4 at 11:59 AM ET, the Built with Google Gemini: Writing Challenge presented by MLH will be an opportunity to show off what you've built with Google Gemini, reflect on your experience, and share what you're up to next! Whether you competed at an MLH hackathon, tackled a DEV Challenge, or hacked on something independently with Google Gemini as your go-to, we want to hear about it.

Five winners will walk away with a Raspberry Pi AI Kit for writing the best articles. As is tradition with DEV Challenges, all participants will receive a completion badge.

Read on for details!

Our Prompt: Hack, Reflect, Look Forward

Every great project starts with a spark, and every great builder knows that the learning doesn't simply end because the deadline hits.

Write a reflection post about a coding event or dedicated project where you used Google Gemini. This could be an MLH hackathon, a DEV Challenge, or any other event you've participated in recently. Look back on what you built, what surprised you, and where you're headed next.

Your post should cover:

What you built with Google Gemini: give us the overview! What was the project, what problem did it solve, and what role did AI play? If your project was deployed on Cloud Run, please embed it.
What you learned: technical skills, soft skills, unexpected lessons. What stuck with you?
Your Google Gemini Feedback: what worked well? Were there moments where you needed more support or ran into friction? Don't be afraid to be candid. We want to read about the good, the bad, and the ugly.

The best submissions will offer a window into your process, your growth, and your perspective as a builder.

Judging Criteria and Prizes

All submissions will be evaluated on:

Style and Presentation
Technical Depth
Clarity
Originality

5 Winners will each receive:

Raspberry Pi 5 8GB GenAI Kit (Assembled)
DEV++ Membership
Exclusive DEV Badge

All participants with a valid submission will receive a completion badge on their DEV profile.

How To Participate

In order to participate, you will need to publish a post using the following submission template:
