Manus, the autonomous AI agent platform, just shipped a /game-dev skill that takes a plain-text description of a game and returns a working, deployed, shareable link. No Unity, no Godot, no JavaScript knowledge required. You describe the game, Manus builds it.
From prompt to playable link
The workflow is exactly as simple as it sounds. You type /game-dev in the Manus chat, describe what you want, and the agent handles the rest: planning the game logic, writing the code, generating assets, testing the build, and deploying it to a public URL you can share with anyone.
Under the hood, when you submit a game idea, the system deploys three specialized agents: a Planner Agent that breaks down your concept into actionable development tasks, an Execution Agent that implements the planned features, and a Verification Agent that monitors results and triggers corrections when needed. This isn't a single LLM call -- it's a coordinated pipeline.
The open-source foundation for the skill comes from @alex_erm, a contributor whose public papca HTML repository on GitHub Manus credited as the basis for the feature. Manus built their /game-dev skill on top of that work and packaged it into their Agent Skills system.
What the Skills system actually is
To understand why this matters, you need to know how Manus Skills work. Think of a Skill as an operating manual you hand your AI agent. It packages domain knowledge, procedures, and best practices into a reusable module. To ensure that the specific Skill you need is activated precisely when you need it, you can use slash commands in the chat box. By typing
