Read your daily Working Memory briefing to understand current context. Contains active focus areas, priorities, unresolved flags, and recent knowledge changes. Load this automatically at the beginning of sessions for cross-tool continuity.
compare-against-empty-list
by blockscout
Optimize list checks by comparing against empty lists instead of using length/1. Avoid expensive list traversal operations when checking if a list is empty or has elements. Use pattern matching or empty list comparison for better performance.
efficient-list-building
by blockscout
Build lists efficiently using prepend operations and Enum.reverse/1 instead of append. Appending to lists is O(n) while prepending is O(1). Use [head tail] notation and reverse at the end when order matters.
elixir-idioms
by oliver-kriska
Idiomatic Elixir patterns, BEAM architecture, OTP patterns, and best practices. Load when writing Elixir code to ensure idiomatic style.
