# Unity ECS Patterns

Production patterns for Unity's Data-Oriented Technology Stack (DOTS) including Entity Component System, Job System, and Burst Compiler.

## Use this skill when

- Building high-performance Unity games
- Managing thousands of entities efficiently
- Implementing data-oriented game systems
- Optimizing CPU-bound game logic
- Converting OOP game code to ECS
- Using Jobs and Burst for parallelization

## Do not use this skill when

- The task is unrelated to unity ecs patterns
- You need a different domain or tool outside this scope

## Instructions

- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open `resources/implementation-playbook.md`.

## Example

```text
Implement Speed plus a MovementSystem using the pinned Entities package. Profile a fixed entity cohort before/after; verify movement once per frame and job dependencies before enabling parallel execution.
```

## Resources

- `resources/implementation-playbook.md` for detailed patterns and examples.

## Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
