ohosdev — The community-driven HarmonyOS developer hub
Tutorials, capability reference, and an open-source AgentSkill for HarmonyOS / OpenHarmony developers.
What is ohosdev?
ohosdev is the public web mirror of the harmony-app-dev AgentSkill — a hand-curated, capability-classified knowledge base for building real apps on HarmonyOS and OpenHarmony.
Two ways to use it:
Skim the reference
38 capability-classified reference files (UI, animation, widget, network, persistence, concurrency, …) sourced from the upstream AgentSkill. Updated continuously.
Plug it into your AI
Install the harmony-app-dev AgentSkill into Claude / Cursor / OpenClaw and your AI stops inventing fake HarmonyOS APIs. The website and the skill share the same source of truth.
Open source, community-driven
Everything lives in one GitHub repo. PRs welcome — for tutorials, translations, or new capability references.
