Expert assistant for ArkTS-JS Interoperability in ArkCompiler (ArkTS runtime). 触发场景：修改/调试 ArkCompiler 互操作层代码（static_core/plugins/ets/runtime/interop_js/）、实现 ArkTS 与 JS 跨语言调用、处理 ETS 和 JS 之间的值转换（js_convert/JSRefConvert）、分析 Interop 内存泄漏与 GC 安全点、以及进行相关代码规范审查。
Guide for adding and maintaining ArkTS <-> JS/TS interoperability tests in ArkCompiler. 触发场景：在 plugins/ets/tests/interop_js/tests/ 目录下创建新的 ArkTS 与 JS/TS 互操作（Interop）测试用例、调试/维护已有 Interop 测试、编写 C++ 运行器（GTest runner）或声明文件（.d.ets）时。
Use when an OpenHarmony C++ change must be checked for call-chain completeness, especially for data propagation, IPC/proxy/stub paths, virtual overrides, callbacks, or dlopen/dlsym boundaries. Produces evidence tables and modification coverage matrices; the helper script only discovers candidate edges.
Use when the user wants to download OpenHarmony daily build images or flash them to a real device (DAYU200/RK3568 or others). Triggers on daily build, DAYU200, RK3568, flashing, burning, hdc reboot, upgrading firmware.
为 C/C++ 项目生成 LLVM libFuzzer FUZZ 测试用例、执行 26 条安全规范审查、生成语义化种子数据。 兼容 OpenHarmony / Linux / Android 构建系统。 触发关键词：fuzz 测试、生成 fuzzer、创建 fuzz 用例、fuzz 规范检查、fuzz_test、LLVMFuzzerTestOneInput、种子数据/corpus
ETS-JavaScript interop Promise bridging system in ArkCompiler. Use this skill when working on cross-language Promise conversion between ETS (ArkTS) and JavaScript, including JSConvertPromise Wrap/Unwrap, EtsPromise proxy creation, EtsPromiseRef bridging, CreatePromiseLink, OnJsPromiseCompleted callbacks, connectPromise, SettleJsPromise, PromiseInteropResolve/Reject, EtsAwaitPromise/AwaitProxyPromise, callback queue management, or any code under js_convert.h (Promise section), js_job_queue, ets_promise, ets_promise_ref, std_core_Promise.cpp, or PromiseInterop.ets. Also use when debugging cross-VM Promise state synchronization, coroutine suspension/resumption during await, or napi_deferred lifecycle issues.
务必在创建、修改、评审或调试 OpenHarmony graphic_2d graphic_test 像素比对测试时使用；只要用户提到 RSGraphicTest、GRAPHIC_TEST、GRAPHIC_TESTS、GRAPHIC_N_TEST、Rosen 渲染测试、RSCanvasNode、RSSurfaceNode、Drawing::Canvas、PixelMap、截图测试、graphic_test 目录或 /data/local/graphic_test 图片，就必须使用。
Use when building or running multimodal input system tests on a real DAYU200 device. Covers NativeToken permission setup, server-side bypass, test binary compile/deploy/run pipeline, phase-based hidumper capture, device discovery polling, and dump field reference.
