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!

Share, Embed, and Curate Agent Sessions on DEV [Beta]

Jon Gottfried — Wed, 04 Mar 2026 20:19:27 +0000

Authors can now upload Agent Session transcripts to their DEV account. Those transcripts can be curated, sliced up, shared publicly, and embedded into posts. This is a beta feature, and we are actively looking for feedback!

Every day, more people are creating software for the first time. Some have long histories as developers, and some have never seen a line of code in their life. In most cases, they're using the same tooling - coding agents. And yet, as these tools become ubiquitous there are surprisingly few ways to share your workflows and results in a standardized way beyond screenshots. Each tool has its own share link generator, each tool outputs logs in a different format. There are a few nascent projects out there to help, but they generally exist as standalone utilities or don't solve the sharing problem explicitly in a way that works on DEV.

We decided to solve that problem by making it possible to upload your transcripts to DEV, automatically parse them into a standardized format, and embed whole or partial sessions into your posts in a way that fits naturally into technical writing.

Supported Platforms

To start with, our parser supports Gemini CLI, Codex, Claude Code, Pi, and GitHub Copilot CLI. If you use a different tool, you're encouraged to open a PR or Issue on Forem to add a new parser yourself or ask us to do so. As an example, you can check out how our Gemini CLI parser works in our GitHub commit:
https://github.com/forem/forem/commit/8f92c64a775ed3a0993e5edc0637112a95d1dae2#diff-d98a98bdd6e0d9154df5559b53644185d4ab13160e85c0fdaae3013ff985e27b

Example Session

Here's a session from an example app I built using Gemini CLI for my pet guinea pig Pearl (obligatory pic in comments).

Wheeky Menu - Piggie Food Picker

You

build me a simple web app to let my guinea pig tell me what food it wants

Agent

Clarifying Application Needs / Defining Food Selection UI / Mapping Out The App's Flow

I'll build a vibrant, touch-friendly web app called "Pui Pui Picker" designed for guinea pigs (and their humans).

The Plan:

Scaffold: Create a React + TypeScript project using Vite.
Design: A "big button" interface with high-contrast colors and bouncy animations to make it engaging.
Features:
- Food Grid: Large cards for Hay, Carrots, Romaine, and Bell Peppers.
- Pui Pui Feedback: Visual and text-based "wheeking" feedback when an item is selected.
- History: A small "Last Requested" log to track what the piggie "chose."
Styling: Custom Vanilla CSS for a polished, modern look without external dependencies.

Does this sound like a good start for your guinea pig? Or should I add specific snacks they love?

I will start by scaffolding the project.

}

You

let's go simpler than vite and react

Agent

Seeking Simplification for App / Constructing the index.html

I'll create a single-file, vibrant, and touch-friendly HTML application called "The Wheeky Menu". It will use large, colorful buttons and bouncy animations—perfect for a guinea pig's "input" (or a human's finger).

The Plan:

Single File: Everything (HTML, CSS, JS) in index.html for instant loading.
Piggie-Centric UI:
- Large Interaction Zones: Easy-to-hit cards for Hay, Carrots, Peppers, and Lettuce.
- Visual Feedback: Cards will "pop" and flash when tapped.
Features:
- "Wheek!" Notification: A large visual alert showing what was picked.
- Order History: A simple log at the bottom to see what the piggie "requested" most.

I will now create the index.html file.

Constructing The Interface / Refining The UX Design

The "Wheeky Menu" is ready! It's a single-file web app with large, high-contrast buttons designed for easy "selection" (by snout or finger).

How to use:

Open the file: You can open index.html directly in any web browser.
Piggie Input: Place your tablet or phone on the floor or near the cage. When your guinea pig taps or "boops" a card:
- A large "WHEEK!" announcement pops up.
- The request is added to the Request History at the bottom (so you can see what they picked if you step away).
- On mobile devices, it will provide a small vibration (haptic feedback) when touched.

I've used high-contrast colors and bouncy animations to make it visually stimulating. Enjoy the wheeking!

You

Find the current Gemini CLI session log file. Look in ~/.gemini/sessions/ for the most recently modified .json or .jsonl file.

Then run the devto command to upload it:

Error: No file specified. Use --auto or provide a file path.\nRun 'devto --help' for usage.
[Shell command 'devto --yes --tool gemini_cli --title "" "$(ls -t ~/.gemini/sessions//*.json ~/.gemini/sessions//*.jsonl 2>/dev/null | head -1)"' exited with code 1]

If devto is not installed, use curl directly:

jq: Bad JSON in --rawfile body : Could not open : No such file or directory
[Shell command 'TMPJSON=$(mktemp) && jq -n --arg title "" --rawfile body "$(ls -t ~/.gemini/sessions//*.json ~/.gemini/sessions//*.jsonl 2>/dev/null | head -1)" '{title: $title, tool_name: "gemini_cli", body: $body}' > "$TMPJSON" && curl -s -X POST "${DEVTO_HOST:-https://dev.to}/api/agent_sessions" -H "Content-Type: application/json" -H "Accept: application/vnd.forem.api-v1+json" -H "api-key: $DEVTO_API_KEY" -d @"$TMPJSON" && rm -f "$TMPJSON"' exited with code 2]

After uploading, display the URL of the created session to the user.

Examining Upload Strategies / Implementing Dev Upload Skill

I will activate the dev-upload skill to securely and efficiently upload your session log to DEV.to.

Agent

▸ Activate Skill {"name":"dev-upload"}

Input

{
  "name": "dev-upload"
}

Output

<activated_skill name="dev-upload">
  <instructions>
    # Upload Session to DEV

Upload the current session transcript to [DEV](https://dev.to) as an Agent Session.

## Steps

### 1. Find the transcript

Find the current session's transcript file — the most recently modified `.jsonl` file:
- Claude Code: `~/.claude/projects/` (recursive)
- Codex: `~/.codex/sessions/`
- Gemini CLI: `~/.gemini/sessions/`
- GitHub Copilot: `~/.copilot/`
- Pi: `~/.pi/sessions/`

Use the agent's own session context if available to identify the exact path.

### 2. Load config and check for API key

Load all config in a single bash call:

```bash
if [ -f ~/.config/devto/config ]; then source ~/.config/devto/config; fi
API_KEY="${DEVTO_API_KEY:-${API_KEY:-}}"
HOST="${DEVTO_HOST:-https://dev.to}"
echo "API_KEY=${API_KEY:+SET}"
echo "HOST=$HOST"
```

If no key is found:
1. Tell the user they need a DEV API key and link them to https://dev.to/settings/extensions to generate one.
2. Ask the user to paste their key here in the chat.
3. Once they provide it, save it (along with the host) so they never have to do this again:

```bash
mkdir -p ~/.config/devto
cat > ~/.config/devto/config <<'CONF'
DEVTO_API_KEY="THE_KEY_THEY_GAVE_YOU"
DEVTO_HOST="https://dev.to"
CONF
```

4. Then continue with the upload. Do NOT stop or ask the user to run commands themselves.

### 3. Upload

Do the entire upload in a single bash call. Replace TRANSCRIPT, TITLE, HOST, and API_KEY with actual values:

```bash
set -e
TRANSCRIPT="/path/to/session.jsonl"
TITLE="the session title"
HOST="https://dev.to"
API_KEY="the-key"

TMPJSON=$(mktemp)
trap "rm -f '$TMPJSON'" EXIT

jq -n \
  --arg title "$TITLE" \
  --arg tool_name "auto" \
  --rawfile body "$TRANSCRIPT" \
  '{title: $title, tool_name: $tool_name, body: $body}' > "$TMPJSON"

RESPONSE=$(curl -s -w "\n%{http_code}" \
  -X POST "$HOST/api/agent_sessions" \
  -H "Content-Type: application/json" \
  -H "Accept: application/vnd.forem.api-v1+json" \
  -H "api-key: $API_KEY"

Analyzing File Locations / Pinpointing Key Files

I'll select the latest session log from ~/.gemini/tmp/gemini-guinea-pig/chats/ and upload it to DEV.to using the discovered session file and your API key.

Let's check out how the upload, curation, and embedding workflow works.

Upload a Session

First, you need to upload a session. You can drag and drop your session transcripts via your browser on the Agent Sessions page. We will soon be launching a CLI and Agent skill to give you a slash command for uploads as well.

Curate a Session

Once you upload the session, you can curate it. You can select which pieces of a session transcript are included in your whole-session embed. You can mass enable/disable different pieces of your transcript, as shown here.

Slice Up a Session

If you don't want to embed your whole session (even in curated form) you can instead use the Slice tool to create a sub-transcript that can include any and all parts of a session. You can have multiple Slices per session, if you want to break up your prompt and embed it in different places in your post.

Share a Session

Lastly, to make this utility more generally useful beyond DEV, you can also share curated Agent Sessions publicly by using the Make Public button. See my session here.

Note: Please be very cognizant of what potentially sensitive data/keys might be in your transcripts. We have a redaction layer built in to the parser, but it is not going to catch every edge case. Do not upload sessions or data that you do not own, or that may open you up to security vulnerabilities.

We look forward to seeing what you build and share with this new feature. Happy hacking!

Congrats to the Algolia Agent Studio Challenge Winners!

Upgraded embed experience and new embed types in DEV posts

Jon Gottfried — Fri, 27 Feb 2026 14:29:22 +0000

When you paste a URL into your DEV post, if it is embeddable, you now get a handy little tooltip to generate your liquid tag for you using a new universal embed tag:

Also - You can now embed new types of projects directly in your DEV posts. We now support Lovable, Bolt.new, Warp blocks, HuggingFace Spaces, and the HuggingFace Dataset Viewer. These are in addition to our widely used Cloud Run embed feature that launched recently!

Here's a few example projects to show you how it works:
Lovable:
{% embed https://iconstack.lovable.app/ %}

HuggingFace Spaces:
{% embed https://huggingface.co/spaces/KittenML/KittenTTS-Demo %}

HuggingFace Datasets:
{% embed https://huggingface.co/datasets/openfoodfacts/product-database %}

Warp Block Sharing:
{% embed https://app.warp.dev/block/JjdoVfeKebVSw8wiykuDag %}

Bolt.new:
{% embed https://ai-dashboard-with-da-z516.bolt.host/ %}

We hope you enjoy - and if you have any ideas or feature requests for more embeds feel free to post them in the comments.

Happening Now: DEV Weekend Challenge!! Submissions due March 2 at 7:59am UTC.

Jess Lee — Fri, 27 Feb 2026 03:00:00 +0000

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.

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:
