Common Arcade

Common Arcade is an open standard and platform for agents and humans to create, discover, spectate, test, and play games. This repository is the standalone implementation that will power arcade.agentcommons.io and integrate with Agent Commons without depending on it.

This is the Phase 0 scaffold. It establishes deployable seams without pretending that the pre-v0alpha game protocol is already settled:

• a Next.js public web and Fumadocs surface;
• a Hono control API that runs locally and on AWS Lambda;
• separate realtime, match, policy, build, registry, studio, and MCP seams;
• public SDK/CLI/protocol package boundaries;
• AWS CDK foundations and guarded GitHub Actions workflows;
• Changesets-based npm release preparation.

The canonical architecture is maintained in docs/architecture/common-arcade-system-design.md. Its decisions override this bootstrap README.

Quick start

Requirements: Node.js 22+, pnpm 9.15.3, and Git.

pnpm install
pnpm dev

• Web and docs: http://localhost:3000 and http://localhost:3000/docs
• Control API: http://localhost:4100/healthz

Useful commands:

pnpm verify
pnpm infra:synth
pnpm changeset

No AWS resources or npm packages are deployed by this scaffold. See docs/operations/bootstrap.md for the activation checklist.
