### Connectivity Framework

Expand Down Expand Up @@ -260,17 +246,17 @@ This release open-sources the entire QuickApp development stack, covering the JS

A lightweight JavaScript engine based on an enhanced fork of Fabrice Bellard's QuickJS. It preserves the original lightweight, fast, and high-compatibility characteristics while integrating a set of new features, especially around developer tooling and debugging support, making it a more complete JavaScript runtime environment.

- [runtime_feature](./../../../../../frameworks_runtimes_feature)
- [runtime_feature](../../../../../frameworks_runtimes_feature)

The QuickApp Feature framework runtime core library and tools. Developed in C/C++ for efficient JavaScript-to-native interoperability. The architecture consists of three core components: a runtime framework that provides a JS-native execution environment, a JIDL (Interface Description Language) and toolchain for auto-generating bi-directional invocation interfaces, and a standardized set of native developer APIs.

- [runtime_ash](./../../../../../frameworks_runtimes_ash)
- [runtime_ash](../../../../../frameworks_runtimes_ash)

The openvela application Shell runtime environment. A lightweight C++ runtime foundation library for embedded systems, providing efficient and reliable low-level components for resource-constrained environments. The modular design covers: resource management (Bundle), system security (Crash handling), device info abstraction (Device Info), file system wrappers (File), file-descriptor management (Scoped FD), message-loop mechanism (Message Loop), stream processing, string conversion, threading, time/timer, networking, memory management, and debug tracing. Built with the GN build system, with CMake support via `CMakeLists.txt`, and compatible with the Kconfig configuration system, suitable for real-time operating systems such as NuttX.

### AI Agent

openvela [AI Agent](./../../../../../packages_ai_agent) is an AI agent engine designed to run on small devices such as watches, speakers, glasses, and earphones. Architecturally, the engine builds a full-stack intelligence pipeline from perception and memory to reasoning and execution, truly enabling devices to make autonomous decisions and deliver proactive services.
