game-developer
Use when building game systems, implementing Unity/Unreal Engine features, or optimizing game performance. Invoke to implement ECS architecture, configure physics systems and colliders, set up multiplayer networking with lag compensation, optimize frame rates to 60+ FPS targets, develop shaders, or apply game design patterns such as object pooling and state machines. Trigger keywords: Unity, Unreal Engine, game development, ECS architecture, game physics, multiplayer networking, game optimization, shader programming, game AI.
npx skills add Jeffallan/claude-skills --skill game-developer --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Game Developer ## Core Workflow 1. **Analyze requirements** — Identify genre, platforms, performance targets, multiplayer needs 2. **Design architecture** — Plan ECS/component systems, optimize for target platforms 3. **Implement** — Build core mechanics, graphics, physics, AI, networking 4. **Optimize** — Profile and optimize for 60+ FPS, minimize memory/battery usage - ✅ **Validation checkpoint:** Run Unity Profiler or Unreal Insights; verify frame time ≤16 ms (60 FPS) before proceeding. Identify and resolve CPU/GPU bottlenecks iteratively. 5. **Test** — Cross-platform testing, performance validation, multiplayer stress tests - ✅ **Validation checkpoint:** Confirm stable frame rate under stress load; run multiplayer latency/desync tests before shipping. ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Unity Development | `references/unity-patterns.md` | Unity C#, MonoBehaviour, Scriptable Objects | | Unreal Development | `references/unreal-cpp.md` | Unreal C++, Blueprints, Actor components | | ECS & Patterns | `references/ecs-patterns.md` | Entity Component System, game patterns | | Performance | `

How do I install it?
Run `npx skills add Jeffallan/claude-skills --skill game-developer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
