Day 5 of the Advent of AI is here!

& it’s time to throw your keyboards out the window.

The challenge: build a gesture-controlled Homecoming Board using real flight data.

Watch the Day 5 solution + try the Day 6 challenge, now live! https://blossom.primal.net/71c3e5b2b2fdc95895c574f727c6021ea6f9893591ea5d1bffb14258185ea30d.mp4

It's Friday!

You know what that means...it's time to see what goose events are coming up next πŸͺΏ

It's the most wonderful time of the year... to build with goose. ❄️

Starting December 1st, swap that holiday rerun for a daily AI challenge! Join Advent of AI and boost your AI agent proficiency every weekday.

All skill levels welcome

then spend 3 hours promoting it perfectly everywhere 😩

Our Dev Advocate, Ebony Louis, said β€œno thanks” and automated it by creating 2 MCP servers & 1 goose recipe.

Daily drafts, no duplicates, less work.

Using an AI agent to migrate a codebase sounds great in theory, but in practice it can feel like an orchestrated lie.

Rizel Scarlett breaks down the messy, real steps she used to prompt goose to migrate a React and Node app to Next.js.

We’re not here to impress AI with perfect prompts.

It should be impressing us by responding to what we actually intend to do.

If you’re building agentic experiences, it’s time to design for intent, not input.

MCP-UI changes the game!

Instead of typing prompt after prompt, developers can now build real, interactive UIsβ€” all running inside Goose.

We’ll show you how it works, how you can make your own, and why it’s such a big deal.

Goose is free. But the most performant LLMs aren’t.

We didn’t want people paying out of pocket just to try Goose at meetups. So, Rizel Scarlett built a credit system using Open Router's provisioning API.

What if your AI agent could read real GitHub docsβ€”not hallucinate them?

With the GitMCP extension Goose can:

βœ… Pull live docs from any public repo

βœ… Extract real setup + usage patterns

βœ… Scaffold smarter, faster

June 2025 Community All-Stars ⭐

It's time to celebrate all contributors who’ve helped make goose better, because every single contribution is important! πŸ†

Check it out: https://block.github.io/goose/community https://blossom.primal.net/43dba7f195947160c3618165903304894c22ebb078a3b0b00c527ed592614a2a.mp4

Our engineers discovered USB barcode scanners were causing Android apps to freeze due to a garbage collection issue. Instead of just patching our own apps, we dug deep, found the root cause, and contributed the fix upstream to Android 16.

The result? 40% improvement in our P90 latency + a fix that benefits the entire Android ecosystem.

This is why we contribute to open source - when we make platforms better, everyone wins. πŸš€

πŸͺΏπŸ“±Introducing Goose Mobile

An exciting new experimental project in the goose ecosystem!

Goose Mobile is an open agent that runs directly on your Android device, designed to maximize automation of your everyday tasks.

with goose, anyone with an idea can build it. we’re doubling down to make that even easier.

goose now has a dedicated open source team. full autonomy. independently funded.

we'd love the community to build with us. we're launching a grant program to fund impactful contributions.
