Day 2: The Storyteller's Booth 🎪📖

Welcome Back, AI Engineer

The Winter Festival's Storyteller has laryngitis!

The Festival organizers are in a panic. They need an interactive experience where visitors can create personalized choose-your-own-adventure stories.

That's where you come in.

Your Task:

Build a choose-your-own-adventure web app with branching story paths, user choices, and beautiful winter styling. Use goose to create the application.

---

NEED LLM CREDITS?

Sign up at goose-credits.dev to get free credits for Claude Sonnet 4.5 via OpenRouter!

Use the ACCESS CODE: ADVENTDAY2

⚠️ You'll need:

• goose (the CLI or Desktop)
• Developer extension enabled (it's enabled by default)

Requirements:

1. Story with at least 3 choice points (branching paths)
2. Multiple possible endings (at least 2)
3. Winter-themed styling (must look festive and magical)
4. Navigation between story segments based on user choices
5. Working file that runs in a browser

Example Output:

A single-page web app that might look like:

╔═══════════════════════════════════════════════╗
║        ❄️ THE WINTER FOREST TALE ❄️          ║
╠═══════════════════════════════════════════════╣
║                                               ║
║  You stand at the edge of an enchanted       ║
║  winter forest. Snowflakes dance in the      ║
║  moonlight, and two paths lie before you.    ║
║                                               ║
║  [🌲 Take the forest path]                   ║
║  [🏔️ Climb the mountain trail]               ║
║                                               ║
╚═══════════════════════════════════════════════╝

🛠️ The Tool: Developer Extension

The developer extension is your AI coding companion - it's enabled by default in goose and gives you powerful capabilities:

Key Tools:

• text_editor: Create, view, and edit files (supports view, write, str_replace, insert, undo_edit)
• shell: Execute commands in your terminal
• analyze: Understand code structure and relationships
• screen_capture: Take screenshots for visual debugging
• image_processor: Process and work with images

For this challenge, you'll primarily see goose use text_editor to create your files. Watch in the UI as goose uses these tools - it's completely transparent about what it's doing!

Three approaches you can take:

1. One-shot prompt: Describe everything you want in one detailed prompt
2. Iterative: Start simple, then refine through conversation (recommended for learning!)
3. Plan: Have goose create a plan before executing!

My go at Day 2!

I built https://storytellers-booth.pages.dev/ with Goose (Claude Sonnet 4.5 + Gemini 3 Pro)

Read more in this Bluesky thread 🧵 https://bsky.app/profile/j4ck.xyz/post/3m6zya3lbsc23

[blackgirlbytes]

i had fun playing this!

[j4ckxyz]

Yayy!

[filiphric]

Here we go, staying up late again to finish the challenge. I recorded a video too, but cannot edit it, will do another one later. but my project is here https://advent-of-ai-day-2.vercel.app/ and I had fun 😂

Also Cursor + Goose session in terminal = ❤️

[blackgirlbytes]

oh wow..this one is so beautiful

[angiejones]

niiice

[filiphric]

Finally made the video walkthrough. Who found the "easter egg"?

[Malgsx]

This is nice!

[nickytonline]

super dope!

[ilnumerotre]

I tried a few things but did not get it to generate nice images for each scene. Now it seems I'm out of credits/tokens.
The choose-your-own-adventure story app works.

[blackgirlbytes]

ah, we'll replenish your tokens for tomorrow's challenge!

[blackgirlbytes]

great job!

[angiejones]

cute

[eriperspective]

I'm impressed with goose and the developer tools. On Day 2 of working with goose and prompts, I created an interactive magical winter wonderland scene and story. The experience features continuous snowfall, a cozy gingerbread house with glowing windows and chimney smoke, and a fluffy polar bear character surrounded by glowing candy cane decorations. When using the mouse, the polar bear can be "tickled," causing it to sparkle; especially when snow lands on its head. With the click of a button, the scene can be viewed in light, dark, or mixed mode. So fun!

Here's my attempt!

After I prompted this, I remembered how powerful Goose actually is. This is a good first attempt but going forward I want this Advent to be more of what I see in my head. I didn't do it over because I don't know how the credits actually worked.

I posted a small snippet of more of the game on BlueSky: https://bsky.app/profile/yabishmish.bsky.social/post/3m72jk37dnc2t

[blackgirlbytes]

Let me know what you mean about the credits. I see that you have unused credits

[nickytonline]

Ended up here for now. Got started late, so there's more I'd like to do, but happy so far with what I have.

TLDR; for features:

• an elf sprite as the main character
• you can restart the game,
• navigate with arrow keys and press spacebar when on a portal
• There's music! Press M to play/pause the music

And here's a quick writeup on it.

You can play the game here

CleanShot.2025-12-02.at.23.59.37.mp4

Added day 2 to my repo.

I started with copy pasta of the requirements and then iterated deciding on an 8-bit game like UI. As I iterated, I kept track of everything in a product requirements document (PRD). I haven't tried one shotting it with my current state of the world for my PRD, but give it a shot!

[4spacesvs1tab]

I have just joined
Here is my repo: https://github.com/4spacesvs1tab/adventofai-day2-storytellers-booth

Vibecoded with Goose (Code Review Mentor Recipe) using qwen3-coder from nano-gpt.com
I am working with Goose as BA is working with Dev (I am no programmer at all):

1. project scope, goal
2. requirements
3. design
4. development: iterative with code review and testing

I really appreciate this Code Review Mentor. For my approach it provides me with structured analysis and documentation which contributes on later phases.

Loving all these entries!

You can check out our Day 2 solution video here:

Day 3 gets a little more interesting, so I'm excited to see what you all come up with!

Here is my Day 2 Submission

https://www.youtube.com/watch?v=pacYcGUHwPc

[craigz]

I've created a public repository to share my various day x challenge solutions at: craigz/adventOfAI_2025 with a day one & day two folder for now (I'm running a day behind and hope to catch up over the weekend). The readme file in the main repo has descriptive entries for each individual project, so I'm not going to put a wall of text here. One thing I added to this day's challenge was a summary of the selected path taken while running the app. I'd also followed one of the given suggestions and added a 'start over' button to the end page. Here are a few screenshots:

Here is my Day 2 submission. I am a bit behind, but here we go nonetheless.

Repo: https://github.com/Malgsx/Advent-of-AI---Block-/tree/main

I set this repo to update every day when I complete a project, so check it out if you get a chance.

We're back (the weather swung hard and missed). Day 2.

I upgraded my Admission Controller to detect "story" requests and inject a StoryGraph policy. The user simply asks for a theme, and the Operator enforces the rest—Single Page App architecture, specific branching depth, and hex-code styling.

User Intent and System Policy can coexist. We don't have to choose between creative freedom and strict architectural compliance; the Operator reconciles both. This is a development from day 1 where only the System policy was applied
