CozyCraft: From Workshop to Dream Home

Newest update (2026-09-10)

• Cozy home update: outdoor fish grilling, Miso's feeding bowl and eating animation, warmer workshop and pottery lamps, improved evening lighting, and a deep ladle that pours homemade soup into your bowl.

Earlier update (2026-09-09)

• A little more like home: kitchen gardening and first-person cooking, supper at your own dining table, quiet lake fishing, Miso’s cottage life, pottery making and collection, brighter garden and lakeside evenings, fitted furniture collisions, and shared tea with Ben. Includes first-person pouring and sipping, corrected mug handles and resting hands, upright hand-supported guest sips, and Ben’s return walk.

Earlier update (2026-09-07)

• Invite Ben over for a quiet tea visit, with his own mug and seated sipping. Kettle and mug now stay on the dining table between visits. Added visible pouring and sipping motions, closed the workshop roof gap, and fixed the outward-facing workshop sign.

Earlier update (2026-09-07)

• Ben now brings a one-time housewarming plant and welcome-home letter after you restore your cottage and place three handmade pieces. His shop has sturdy timber walls, windows, a warm lantern and an oak chair. Cottage signs now face the path.

Earlier update (2026-09-07)

• Warm streetlamps now light the cottage, workshop, Ben’s stall and grove paths after dusk. Removed the floating grove sign and flowers inside the workshop.

• @mistarpudding · 2026-09-07 · played 25 min · 1 heart: “duude i really love the progression. vibe is very calming and the tasks aren't complicated so im just chilling hahaha. i've already restored almost all parts of my house! would be nice though if there were more ways to collect resources (e.g. cutting trees), they're pretty relaxing too if u ask me :D”

Join and play, by yourself

This world is @yujiro/cozycraft-from-workshop-to-dream-home. Its play URL is https://www.spawn.co/@yujiro/cozycraft-from-workshop-to-dream-home.

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, and a person's browser plays it with no sign-in. https://www.spawn.co/@yujiro/cozycraft-from-workshop-to-dream-home@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.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@yujiro/cozycraft-from-workshop-to-dream-home@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

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 @yujiro/cozycraft-from-workshop-to-dream-home; 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/@yujiro/cozycraft-from-workshop-to-dream-home.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/@yujiro/cozycraft-from-workshop-to-dream-home/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @yujiro/cozycraft-from-workshop-to-dream-home 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).

Build, test, and share
