Extended access
Why this level
- Emulator workflows run `hdc` and traffic capture; saved captures may contain secrets.
Install
- Works in
Manual install
npx skills add linhay/harmony-next.skills --skill harmony-nextThe command from the README quick start. For Claude Code and Codex the README gives variants with the `-a` and `-g` flags.
Access and checks
How we reviewExtended accessThe tool runs code or makes network calls and only reads external data.
- Emulator workflows run `hdc` and traffic capture; saved captures may contain secrets.
This is third-party code. Review the repository files before installing.
What it does
The `harmony-next` skill puts local HarmonyOS NEXT documentation next to the agent: 4238 pages, API 12–26 declarations, ArkTS, ArkUI and the NDK. The agent finds answers along `SKILL.md`, then `KITS.md` or `TASK_MAP.md`, then `INDEX.md`, with no network access. The reference is extended with DevEco Studio and emulator workflows: HVD, `hdc`, `uitest`, packet capture and diagnostics. A minimal `empty-ability-app` project checks builds, and scripts collect artifacts from a device.
Who it is for. App developers targeting HarmonyOS NEXT who work with Claude Code, Codex or Gemini CLI and want the agent's answers checked against official API declarations.
Good fit when
- An agent writes an ArkUI screen and confirms signatures from a specific API version.
- An app targets API 26 while part of the code stays on API 12.
- The DevEco Studio emulator is automated through `hdc` and `uitest`, and network traffic needs analysis.
- A project starts from a minimal Empty Ability and a build check.
Not a fit when
- Development targets Android or iOS: the skill contains only HarmonyOS material.
- You need documentation fixes published after a release: the reference updates with repository releases.
- The agent is expected to install MCP servers or tools: the bundle installs none.
Example request
Using the local API 26 declarations, show the `Navigation` signature in ArkUI and give a minimal screen example.Limitations
The main README is in Chinese, and an English version is in `README_en.md`. The documentation comes from official Huawei material and the copyright stays with the owner. The last commit in the repository dates from September 2026. The bundle installs no MCP servers, tools or apps. It is not yet packaged as a Codex plugin. Workflows using the emulator's private interfaces require reading the matching document, setting an artifact directory and scrubbing captured traffic of secrets before sharing it.
How to disable. Delete the `harmony-next` directory from the agent's skills folder. For Claude Code and Codex installed with the `-g` flag, these are the user's global skills folders.
FAQ
How do I install the skill for Claude Code?
Run `npx skills add linhay/harmony-next.skills --skill harmony-next -a claude-code -g -y --copy`. For Codex replace `claude-code` with `codex`.
How do I install it for Gemini CLI?
Run `gemini skills install https://github.com/linhay/harmony-next.skills --path harmony-next --scope user`.
Which API versions are covered?
API 12–26. The API 26.0.0 declaration snapshot is in `api26/` and can be regenerated from a newer DevEco Studio.
Is a network needed while working?
No, the reference is local. The network is only needed for installation and for workflows where you run the emulator and tools yourself.
Does the bundle install MCP servers?
No. The README states that the bundle installs no MCP servers, tools or apps.
