Skill UI

This skill captures and persists critical user decisions, project constraints, and architectural choices across multiple sessions and agents. It saves this context into a structured memory database (`mdbase`), ensuring that future development steps or agents can retrieve the original intent without re-deriving it from scratch. Ideal for documenting project rules, tech stacks, and design rationale.

Design and review MyBatis mappers with XML/annotation SQL, result mapping, dynamic SQL safety, transactions, batching, pagination, and query performance for Java/Spring persistence.
