A new SDK for RuneScape, called RS-SDK, allows users to automate the game using coding agents, optimized for use with tools like Claude Code. The project provides a testing environment for goal-directed program synthesis and research into agent collaboration. It includes a TypeScript SDK, agent documentation, bindings, and a server emulator.

RS-SDK is built on the LostCity engine. The architecture involves a web-based client that connects to the server emulator. A gateway server then forwards messages between the client and SDK instances. This setup enables the SDK to execute low-level actions. The demo server is available for testing, though users are advised to host their own instances.

Key features include faster leveling and infinite run energy. While the project is open-source and community-run, it's strictly for education and research. RS-SDK is not affiliated with Jagex Ltd. The project's goal is to offer a safe space for bot development and agentic techniques.

It's a niche project, but demonstrates the potential for AI-driven automation in gaming. What's next? Expect to see more complex bots and agent interactions as developers refine the SDK. The project's MIT license encourages community contributions and experimentation in the space.
