View design brief YOUR AGENTS
A home for the team. See agents in their own spaces, on the move and at a real handoff.
YOUR PROJECT
A sprint you can see. Turn accepted work into visible growth, with a world that follows the project.
YOUR EXPERIENCE
An experience you can shape. Build an interactive book, a small game, a product story or a place to explore.
YOUR CODEX DOT
Dot has a place here, too. Give your Dot agent a cozy room, a garden or somewhere entirely unexpected.
Your starting point A picture. A sketch. A few words.Bring your own art, or describe what you want to build.
One possibility A place for your agents. Rooms to work in, a shared world and visible handoffs.
Another possibility An experience of its own. A living story, a small game or an interactive product world. No agents required.
I HAVE AN IDEA Start with an idea. Describe the place you imagine. The plugin can help create the art with available image tools, then build a world around it.
Help me make the art ↗ I HAVE THE ART Work from your own art. Upload your drawings, a reference image or an art folder. Keep your visual identity and shape how the world moves and responds.
Bring my own artwork ↗ A HOME FOR YOUR CODEX DOT AGENT
Dot has a place here, too. A workspace, a retreat or somewhere unexpected. Give your Codex Dot agent a place in your world.
Or leave the characters out and simply make a place to explore.

YOUR FIRST WORLD, IN THREE SMALL STEPS
Picture it. Describe it. Shape it. Come with a project, or come with an idea. The starting point is yours.
Follow the setup guide ↗ Choose your starting point. New project, existing team, or a world-only experience. Bring an image or a description. Use your art, or ask for help creating it. Build it, explore it, make it yours. Refine the scene and interactions with your world owner. GOOD IDEAS CAN TRAVEL
Bring a world in. Take an idea with you. Learn how portable world definitions, agent briefs and plugin rules move between projects.
Import & export guide ↗ BUILDING ALIFE WORLDS, WITH ALIFE WORLDS
Watch the plugin come to life. The connected project world is a way to follow the plugin's own work: a goal becomes a sprint, work moves between agents, and accepted progress grows toward a finished release.
It is the same idea you can use for your own project—see the work in a world, and follow it all the way to done.
LIVE BUILD VIEW From work in progress to a world you can use. The TV above follows the published project world. Its progress, version and last snapshot come from the public feed.

Default world Describe a new world Use my artwork
What would you like to create?
3. Choose your agents Start with the default team, bring your own roles, or keep the agents you already have.
Default starting team Custom agents Agents in this project Agents from another folder No on-screen agent characters
Your roles and prompts Agent Support prepares the selected roles with the full project rules and approved settings.
The plugin checks this project's agents first and keeps their current work, chats and settings.
Select the external project folder in Codex. Only the agents you explicitly select are linked; their chats, files, work and settings stay in place.
The scene has no visible agent characters. The plugin's setup and world-building roles can still work behind the scenes.
Your world creation prompt Create the place first. This prompt sets up your world and the agents you choose.
Next: set a goal and plan sprints Copy world creation prompt

× MAKE IT YOURS
Start from Midnight Colony. Copy this design brief into your project chat. The plugin's world owner handles the implementation; copying a prompt creates no agents.
Use my installed ALife Worlds plugin to create a separate cozy pixel woodland world inspired by Midnight Colony. Use top-down ants and open organic dirt rooms, warm soil, rain, layered pine scenery and a canonical sprint tree. Preserve existing agents, settings, tasks, privacy and world rules. Work from my supplied artwork and keep the current working world recoverable. Treat scenery and mining as visual interactions, never task progress. Copy world prompt
× WORLD CONCEPT
Your next world.
Art concept from the supplied design study. The picture is a visual reference, not a ready-made interactive world package.
