ohos-scrcpy-app: Instructions file for Claude Code

CLAUDE.md

ohos-scrcpy-app CLAUDE.md is an instructions file for Claude Code from guoxiucai/ohos-scrcpy-app. It costs 2,446 tokens per session, scanned A, original, MIT.

A repository instruction file for an OpenHarmony screen-mirroring and device-control application. It documents the Flutter desktop client, the device-side service, the communication protocol, and rules such as using Simplified Chinese and preserving fixed design decisions.

In plain words
What is it for?
Use it when modifying screen streaming, touch or key input, HAP installation, device commands, the HDC connection, or the Flutter desktop interface.
Why use it?
It gives coding agents the technical context needed to change this multi-part application without breaking its device connection or changing agreed architecture.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md.

This is guoxiucai/ohos-scrcpy-app's own configuration. It tells Claude Code how to work on ohos-scrcpy-app itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ohos-scrcpy-app configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/qingwei/Library/OpenHarmony/Sdk/20/ets/api/.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ohos-scrcpy-app CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

关键技术决策（已与用户对齐，勿擅自改动）

  • HDC 调用方式：客户端 Process.run 调系统 hdc CLI，优先内置 hdc 二进制文件，其次本机 hdc PATH。
  • 视频解码：平台原生硬解（macOS VideoToolbox / Windows MediaFoundation），通过 MethodChannel + Flutter Texture 上屏。不用 media_kit / fvp / ffi+ffmpeg。
  • 传输通道：仅 hdc fport tcp:<pcPort> tcp:53535，USB/网络 hdc 共用同一通道，不做设备 LAN 直连。
  • 服务端保活与自启：完全交给 app.json5 中已配置的 keepAlive，不写 BootReceiver/StaticSubscriber，不申请 MANAGE_APP_KEEP_ALIVE / RECEIVER_STARTUP_COMPLETED。
  • mainElement：module.json5 的 mainElement 必须指向 ScrcpyService（ServiceExtensionAbility），UIAbility 仅作调试 UI 入口，不放业务逻辑。
  • API 区间：compatibleSdkVersion: 15，compileSdkVersion: 23。

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
