HarmonyOS Skills

ArkTS (HarmonyOS) language rules and constraints for writing correct, compilable .ets code. ArkTS is based on TypeScript but removes most dynamic features for AOT compilation. TRIGGER when: writing or editing .ets files, generating ArkTS code, fixing ArkTS compilation errors, migrating TypeScript to ArkTS, or any HarmonyOS application development involving ArkTS code. Triggers on: ArkTS, HarmonyOS code, .ets file, ETS, arkts compilation error, HarmonyOS app development, write ArkTS, generate ETS code, fix ArkTS error, HarmonyOS component, ArkUI. Do NOT trigger for: pure TypeScript projects, general JavaScript questions, non-HarmonyOS mobile development.

HarmonyOS官方文档快速查找Skill。在skill内部的references文件夹（包含2860个markdown文件）中高效检索开发文档、API参考、开发指导、常见问题等。使用三步查找法：先文件名匹配缩小范围，再内容搜索精确定位，最后读取目标文件。当用户开发HarmonyOS应用或插件时使用，适合API用法、功能实现、错误排查、Kit介绍、组件使用等任何需要查阅官方文档的情况。触发关键词：HarmonyOS开发、鸿蒙开发、鸿蒙适配、鸿蒙文档、ArkTS开发指导、@ohos API、Kit文档、组件用法、错误码查询、开发指南、如何实现、常见问题等。

Search HarmonyOS API reference Markdown files in api-references to find modules, API signatures, types, permissions, system capabilities, examples, and feature-level implementation guidance. Use when looking up HarmonyOS/OpenHarmony/HMS APIs, ArkTS APIs, Kit documentation, @ohos or @hms modules, system capabilities, permissions, or when adapting code to HarmonyOS. The api-references file names include Kit names, so always search file names first before content.
