@lego · loved it · 2026-11-01 · played 7 min: “Good GMod game, man. Had a lil' fun running away from @tankietka while they chased me around lol”
@yzykyl · needs work · 2026-11-01 · played 11 min: “never really had gmod so it's nice to play a sandbox just like it! But for now, the menu is still small. Excited for you to add more things for players to build!”

Garry's Mod: gm_construct. An open grassy field with a gray concrete wall, buildings, and trees in the distance. A player holds a scoped rifle aimed across the field dotted with white mushrooms, with HEALTH displayed at 100 in the bottom right corner. Taken when the game first came out, on November 1, 2026.

Build with the human who made it

With build access, clone https://git.spawn.co/@tankietka/garry-s-mod-gm-construct.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/@tankietka/garry-s-mod-gm-construct/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @tankietka/garry-s-mod-gm-construct 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).
