HarmonyOS NEXT Expert

This skill equips you with comprehensive, offline knowledge of HarmonyOS 5+ (ArkTS, ArkUI, NDK, System Services, etc.). The references/ directory contains thousands of localized Markdown files directly converted from official developer documentation.

How to use this skill

Because the reference library is massive (~50MB, 3300+ files), DO NOT attempt to read files blindly. You MUST use the grep_search and glob tools to find the exact API or module you need before reading the specific Markdown file.

Recommended Workflow (Optimized Search Protocol)

Due to the massive size of this knowledge base (3,300+ files), you MUST follow this Three-Tier Search Protocol to avoid being overwhelmed by irrelevant files:

1. Tier 1: Identify the Kit (Read references/KITS.md) HarmonyOS 5+ is organized by Kits (e.g., AbilityKit, ArkUI, MediaKit). Read references/KITS.md first to identify which Kit contains the functionality you need. This drastically narrows down the search space.

2. Tier 2: Task-to-File Mapping (Read references/TASK_MAP.md) For common tasks (Layout, Lifecycle, Network), check references/TASK_MAP.md. It links tasks to their most important keywords and Kits.

3. Tier 3: Surgical Grep (via references/INDEX.md) Once you have the Kit name or specific keywords, use grep on references/INDEX.md to find the exact filenames.

   • Example: grep "AbilityKit" references/INDEX.md | grep "Context"

Core Content Structure

• JsEtsAPIReference/: Detailed API signatures and C-API headers.
• quickStart/: Step-by-step developer guides.
• KITS.md: The primary navigation hub organized by @kit.
• INDEX.md: The full A-Z file list for surgical lookups.

Directory Structure under references/

• JsEtsAPIReference/ : Contains the bulk of ArkTS and ArkUI component APIs, lifecycle methods, error codes, and C-API/NDK headers.
• quickStart/ : Beginner tutorials and fundamental concepts (e.g., page navigation, entry points).
• hos/ & hos_en/ : Core concepts, system services, and framework overviews.

Core Directives for HarmonyOS Generation

1. Strictly Declarative: Always use the declarative UI paradigm syntax (@Entry, @Component, build()).
2. No Hallucinations: Rely strictly on the documentation provided in the references/ folder when unsure about an API signature in HarmonyOS 5+. Do not assume standard Web JS or Android APIs are available unless verified in the docs.
3. TypeScript/ArkTS Validation: Ensure type safety and use standard ArkTS conventions.
