# Unreal Unreal GAS Reference

## Purpose

Gameplay Ability System abilities, attributes, effects, tags, prediction, and replication risk.

## Guidance

- Select this reference only when the task names or clearly implies GAS.
- Identify package/plugin version, project files changed, and validation evidence.
- Avoid making this plugin mandatory for unrelated lightweight prototype work.

## Validation

- Prefer project-local engine commands and Codex Game Studio project validation before readiness claims.
- Record unknown version-specific behavior as a risk instead of presenting it as confirmed.
- Keep this reference selected by relevance; do not load every engine reference for one task.
