以下为本文档的中文说明LobeHub内置工具包构建指南专门用于开发和集成LobeHub平台中可被代理调用的工具。该技能定义了内置工具的五大核心组件Manifest与类型定义为LLM提供工具规范和系统提示、ExecutionRuntime执行运行时负责服务器端和桌面端的实际调用、Executor执行器客户端侧的交互逻辑、Inspector检查器用于调试和验证工具行为、以及Render渲染器负责工具输出在界面中的呈现。此外还涵盖流式处理、干预机制、Portal集成和工具注册表等高级功能。使用场景主要包括为LobeHub平台添加新的Agent可调用工具、开发工具包的各面层组件、配置工具的Manifest和类型系统、实现工具的流式响应处理、以及将工具注册到工具注册表中供代理发现和使用。核心原则强调五面一体的架构设计——每个工具由五个独立但协同的组件构成分别服务于LLM、运行时、客户端、调试和UI渲染等不同层面。这种分层架构确保了工具的灵活性、可测试性和可维护性。Builtin Tool Authoring GuideA builtin tool is a package the agent runtime can call.

It doubles as the runtime listBaseExecutoriterates over.Three result fields, three audiences:content: string→ the LLM reads itstate: Record…→ the UI’spluginState;result-domain only, never echo all params backerror: { type, message, body? }→ both LLM and UI;typeis a stable codeSplit execution from frontend wiring.src/ExecutionRuntime/— pure runtime, no React, no Zustand, accepts services via constructor.The default place for new logic.src/client/executor/—BaseExecutorsubclass that callsExecutionRuntime(or stores/services directly when frontend-only).UI defaults to “do nothing”.Inspector is required (the header strip). Render/Placeholder/Streaming/Intervention/Portal are addedonly when there’s something specific to show— empty registries are fine.Style withcreateStaticStyles cssVar.*(zero-runtime). Fall back tocreateStyles tokenonly when you genuinely need runtime values.
