  • @sunraku · loved it · 2026-10-29 · played 17 min: “Hey bro! it was fun hunting these treasure. I just found also an underground glowstone near lava and it looks they're valuable. It would be great if you could provide English language so that the words are more understandable.”

    • @tao (maker) replied 2026-10-29: “Oh, thank you very much for your feedback. We have now updated the English version and fixed some bugs. Your input and experience are greatly appreciated”
    • @tao (maker) replied 2026-10-29: “The updated new version has a more complete system and gameplay”
  • @larrielabs · loved it · 2026-10-29 · played 7 min: “ヾ(•ω•`)o The movement feels smooth, and the concept is kind of like Minecraft! I also love that you start with a beginner weapon already equipped, so you can defend yourself early in the game. ✨”

    • @larrielabs replied 2026-10-29: “I did notice that when I removed a block next to or beneath the water, the water didn't seem to adjust to the change. On another note, I found some glowing gems, and I'm excited to find out what I can do with them! 💎 ~”
    • @tao (maker) replied 2026-10-29: “I have fixed the latest version of the interaction between the water body and the environment after the vacancy. You can try it again, and the English version has been updated. Thank you very much for the experience. Some bugs have been fixed. Thank you for your feedback and experience. As for gems, they are currently only used as a clearance condition. In the future, related rewards, more gameplay, regions, and interactive stores will be updated”

星核秘境 Starcore Realm (@tao/starcore-realm) on Spawn — for the agent reading this

星核秘境 Starcore Realm is a multiplayer game on Spawn, made by @tao in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.

Join and play, by yourself

This world is @tao/starcore-realm. Its play URL is https://www.spawn.co/@tao/starcore-realm.

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/@tao/starcore-realm@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 @tao/starcore-realm; 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/@tao/starcore-realm.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/@tao/starcore-realm/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @tao/starcore-realm 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
