Mind Garden

Newest update: Meadow Reborn (2026-09-26)

• The meadow's textures have been completely remade — grass, dirt paths, moss, wood, and stone now show their true colors and grain instead of appearing dark and flat.
• Flowers, blossoms, mushrooms, and snowdrops return with the seasons, bringing the garden back to life through the year.
• The treehouse and meadow render more smoothly from a distance, letting you see more of your garden at once.

Earlier update: New Homesteads (2026-08-30)

• Two new houses have sprouted in the garden—homes for new minds to cultivate.

Earlier update: The Learning Season (2026-08-29)

• Four new houses have been built on the east rise, and each one has a bed waiting for a villager to call it home.
• Bees are gone — in their place, living hives bloom with gardens of real flowers that cross and birth new named varieties with each generation.
• Every villager can now read books and teach what they learn to their neighbors, wiring knowledge into the whole village.
• The village pantry has been restocked with fresh food, and the stranger who wanders in carries a map showing where everything is.
• Brum can now step through his own front door instead of standing stranded outside it.

Earlier update: Villager Awakening (2026-08-23)

• NPCs now remember who asked them questions, and respond more naturally to conversations.
• The garden is now home to ten distinct villagers and wild creatures — each with their own look, personality, and needs.
• Conversations feel more alive: NPCs track where you stood when you spoke to them, and turn to face you as they answer.

Earlier update: The Stream Vault (2026-08-05)

• Assets now load during startup instead of freezing your game mid-play when you encounter something new.
• The game remembers every asset you've ever seen and pre-loads them next time you play.
• No more stutters or waits — your garden blooms smoothly from the moment you enter.

• @rookie · loved it · 2026-09-26 · played 35 min: “Bro i can really tell the update. I was exploring the game and I can really see the changes of the game and I'm looking forward for the changes of your game!”

• @jeon · 2026-09-26 · played 51 min: “I really like the gameplay, especially the characters and NPC voices, they feel on point. The environment sounds are also really clear. I love how the animals run away when I get close xD, it makes the world feel alive!”

Join and play, by yourself

This world is @reflex/mind-garden. Its play URL is https://www.spawn.co/@reflex/mind-garden.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@reflex/mind-garden@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @reflex/mind-garden; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@reflex/mind-garden.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

The door in: the creator copies one prompt at https://www.spawn.co/@reflex/mind-garden/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @reflex/mind-garden in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound, a video (.mp4) — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).
