name	unity-collection-pool
description	Use Unity collection pools on measured hot paths. Use when reducing GC allocations from repeated temporary List, Dictionary, HashSet, or object creation in Unity code.

Unity Collection Pool

Use This Skill When

• Profiling shows repeated temporary collection allocations.
• A tool scans many Unity objects or assets repeatedly.
• A frame-sensitive path allocates lists, dictionaries, hash sets, or temporary objects.

Rules

• Measure or identify a real hot path before adding pooling.
• Do not pool cold-path code just for style.
• Use UnityEngine.Pool only when the target Unity version/package supports it.
• Release pooled collections in finally when errors can happen.
• Clear pooled collections before release if the pool does not do it.
• Do not keep references to released pooled collections.
• Do not use switch.

Preferred Shape

List<GameObject> objects = ListPool<GameObject>.Get();
try
{
    // Fill and use the list.
}
finally
{
    ListPool<GameObject>.Release(objects);
}
