Use when adding multiplayer or netcode to a game — client-server vs P2P, server authority and anti-cheat, state replication vs RPCs, prediction and reconciliation, lag compensation, plus Godot 4 / Unity NGO / Unreal wiring. NOT single-player gameplay (that is `godot`, `unity`, `unreal`), NOT matchmaking or server hosting (that is `deployment`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Game multiplayer & netcode Design and wire the network layer of a game across Godot 4.x, Unity, and Unreal: choose a topology, put authority in the right place, replicate the right state, and hide latency without opening the door to cheaters. This skill owns the *networking* decisions; the engine skills own the local gameplay those decisions sit on top of. Route elsewhere when the ask is not netcode: | The ask | Route to | Why not here | | --- | --- | --- | | Single-player movement, AI, input, animation, save files | [`godot`](../godot/SKILL.md) / [`unity`](../unity/SKILL.md) / [`unreal`](../unreal/SKILL.md) | The engine skill owns local gameplay; no network dimension. | | Physics determinism, collision, character controllers | [`gamedev-physics`](../gamedev-physics/SKILL.md) | Netcode *consumes* determinism; it does not own the physics fix. | | Matchmaking, lobby backend, dedicated-server hosting, relays, DB, game-server CI | [`deployment`](../deployment/SKILL.md) | Running the fleet, not designing the in-game net layer. | | Web realtime — chat, presence, a generic WebSocket app | [`webhooks`](../webhooks/SKILL.md) | Not a game world/simulation. | …

How to install
mdr add ericrisco/rsc-harness/gamedev-multiplayer@sha256:f6a3ecedbaa4b72bThe line at the top of this page pins the label git:20260729.a1a8f66, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
