+description: Design clean Bevy ECS layouts with components, resources, events, systems, and states
+license: MIT
+compatibility: opencode
+metadata:
+  stack: bevy
+  language: rust
+---
+
+## What I do
+
+- turn game idea into ECS parts
+- split data across components, resources, and events
+- propose system boundaries
+- suggest state flow
+- keep Bevy code idiomatic and small
+
+## When to use me
+
+Use when:
+- new mechanic starts
+- code feels like one giant system
+- feature needs plugin split
+- event vs resource choice unclear
+
+## Output shape
+
+1. goal
+2. ECS map
+3. file plan
+4. patch order
+5. verify commands
+
+## Rules
+
+- prefer Bevy built-ins before extra crates
+- keep `main.rs` thin
+- prefer events for loose coupling
+- prefer states for app flow
+- keep names specific
