For developers, the more consequential question is what can be built reliably. Huawei's HDC 2026 materials describe HarmonyOS 7 capabilities around agent frameworks, cross-device interaction, space computing, security, and performance. Those features will matter only if the development tools make them testable and the documentation makes their limits clear.",[16,17,19],"h2",{"id":18},"the-cost-of-a-new-capability","The cost of a new capability",[12,21,22],{},"An API is not finished when it can produce a demo. Developers need versioned documentation, sample projects, simulator support, debugging tools, performance guidance, and a clear compatibility matrix. They also need to know what happens when a device lacks a sensor, a network connection drops, or a permission is denied.",[12,24,25],{},"Agent features raise the bar because they combine model behavior with application state. A developer must test not just the successful path but also ambiguity, partial completion, duplicate actions, and user cancellation. Good tooling should make those cases visible instead of hiding them behind a polished interface.",[16,27,29],{"id":28},"one-codebase-many-devices","One codebase, many devices",[12,31,32],{},"HarmonyOS's cross-device proposition can reduce duplicated work, but multi-device support introduces its own testing matrix.
