What problem does it solve? Writing MapleStory Worlds scripts requires platform-specific knowledge that general Lua experience does not cover: mlua annotations, execution spaces, property sync, and the event system. Guessing APIs or applying Unity-style patterns produces code that compiles but silently fails at runtime, and this Skill prevents those failures with verified workflows. ## Core Features & Use Cases - Script Authoring Rules: Enforces correct use of @Component/@Logic declarations, ExecSpace annotations, lifecycle methods, property sync (@Sync, SyncTable), and the event system (ConnectEvent, @EventSender). - API Verification Workflow: Requires checking engine API signatures in Environment/NativeScripts .d.mlua files before writing code, with LSP diagnostics after every edit. - Playtest & Debug Loop: Provides a structured verify checklist covering build logs, runtime logs, log-evidence requirements, and DataStorage cost-safe patterns. - Use Case: When asked to add a monster AI component to a MapleStory Worlds project, the Skill searches existing scripts first, verifies API signatures, writes the .mlua in the correct feature folder, refreshes the Maker, and validates via build and runtime logs. ## Quick Start Ask the AI to create a new MapleStory Worlds component script, such as a monster chase AI, and have it verify the result through build and runtime logs.
