Apex Collections Patterns

Agent skill
1 skill

Use when designing, reviewing, or debugging Apex code that relies on List, Set, or Map collections in triggers, batch classes, or service layers — especially for bulkification, heap management, and safe null handling. Trigger keywords: 'Map ', 'containsKey', 'retainAll', 'putAll', 'Set intersection', 'heap limit', 'collection in loop', 'unbounded accumulation'. NOT for SOQL query optimization (use soql-fundamentals), NOT for async job design (use apex-queueable-patterns or batch-apex-patterns), NOT for platform cache strategies (use platform-cache).
