DevEco CLI: Open HarmonyOS Development to AI Agents via Command Line

DevEco CLI is a new command-line interface designed to make HarmonyOS application development capabilities accessible to AI agents and existing AI-assisted workflows. It addresses the challenge that AI coding tools often lack understanding of HarmonyOS-specific conventions, toolchains, and authoritative knowledge.

One-Command Agent Integration

Developers can install the bundled deveco-cli Skill into multiple local AI agents (e.g., OpenCode) with a single init command. This teaches the agent how to drive DevEco CLI, enabling it to execute the full HarmonyOS development loop — from project creation through compilation, deployment, and debugging — without manual IDE interaction.

Full-Lifecycle Command Coverage

DevEco CLI exposes a stable, agent-friendly command set that spans the entire development journey: devecocli create — initialize a project devecocli check — syntax and static analysis devecocli device / emulator — manage physical devices and simulators devecocli build — compile and package devecocli run — deploy to target device devecocli log — collect debug logs

These commands replace multi-step manual IDE operations with scriptable, automatable calls, improving consistency and efficiency.

Local, Agent-Optimized Knowledge Base

DevEco CLI ships a curated HarmonyOS knowledge base deployed locally (no cloud dependency). It covers best practices (innovative features, multi-device, security, AI enablement), development guides (app framework, ArkUI, media, security, tooling), API references (app framework, system security, audio/video, graphics), and version notes (positioning, compatibility, upgrade strategy, device support matrix, API version distribution).

Retrieval is optimized for agents: progressive loading returns titles and summaries first; a built-in HarmonyOS terminology dictionary handles SDK-specific vocabulary; API queries prioritize official references (e.g., UIAbility); results are structured for easy parsing.

70+ Curated Skills Encoding Expert Experience

Skills are not mere prompt collections but distilled engineering knowledge: historical bug patterns, platform norms, typical scenarios, and methodological practices. They help agents generate platform-conformant code and reduce trial-and-error.

A highlighted example is the multi-device adaptation suite — seven Skills prefixed hmos-multidevice covering screen orientation/rotation, hardware capability differentiation, responsive layout, safe-area avoidance, cross-device interaction, and fold-state adaptation (dual-fold, tri-fold). Agents leveraging these Skills can produce layouts that respect complex form factors instead of naive stretching, significantly cutting manual adaptation effort.

GeWu Skills Plaza: Discovery, Quality, and Community

The OpenHarmony community's GeWu platform serves as a centralized Skills marketplace. It solves three problems:

Discoverability — aggregates first- and third-party Skills across the full development lifecycle, searchable by tag, category, organization, or business scenario.

Quality assurance — a rating system evaluates compatibility, performance, security, and community scores, backed by onboarding review, automated testing, security scanning, and human audit.

Reuse and co-creation — encourages publishing reusable Skills to avoid duplicated effort, fostering a virtuous cycle of experience accumulation and ecosystem growth.

Getting Started
