Game Development Expert

Real-time game development problems

Frame drops, physics tunneling, and inconsistent multiplayer state are usually not one bad snippet. They come from coupled system boundaries, data layout, and sync models. The Game Development Expert skill is aimed at real-time game contexts, helping engineers reason about ECS, physics, network synchronization, and performance profiling instead of producing generic code.

How it works and what it outputs

The skill follows a structured workflow:

• Scope: confirm engine, gameplay, target frame rate, and platform.
• Design: split system boundaries, data structures, and synchronization model.
• Implementation: propose ECS systems, physics configuration, and networking code direction.
• Self-check: inspect GC pressure, Draw Calls, determinism, object pooling, and parallel jobs.
• Artifact: emit a GameSystemSpec with fields such as system, engine, perf, and notes for downstream review.

It is useful for turning symptoms such as combat frame drops, unstable collisions, or sync latency into reviewable engineering artifacts, not for replacing engine source modifications.

Boundaries and notes

It is best for real-time rendered game projects, not ordinary web backends, static sites, or non-game products. For engine internals or low-level renderer changes, it provides direction and checklists rather than official engine support. Supply specific symptoms, target platform, and existing code snippets to make the output closer to implementation.
