Memory Bank System is a hierarchical task management framework designed to work with Cursor 2.0 AI coding assistant. It defines custom commands (/van, /plan, /creative, /build, /reflect, /archive) that guide AI through distinct phases of a development workflow. The system uses markdown-based memory files including tasks.md, activeContext.md, and progress.md to maintain persistent state across sessions. It employs token-optimized rules and visual process maps to structure how the AI approaches and progresses through coding tasks.
