Core Capability Overview

Model Chat

Supports offline Mock model, OpenAI-compatible APIs, and DeepSeek APIs, covering chat, streaming, cancellation, and error handling.

Capability Details

A unified ChatModel abstraction wraps model requests. Application code builds a ChatRequest and listens to ChatReply signals for deltas, final output, and errors.

Call Example

ChatRequest request;
request.addSystemMessage("你是 Qt 应用助手。");
request.addUserMessage("分析当前设备状态。");

ChatReply* reply = model->chat(request, {}, this);
connect(reply, &ChatReply::deltaReceived, this, &Panel::appendText);
connect(reply, &ChatReply::finished, this, &Panel::finishText);

Prompt and Chain

Provides PromptTemplate, ChatPromptTemplate, Runnable Chain, and Parallel branches to compose prompts, models, and parsers into business flows.

Capability Details

Prompt templates handle variable substitution, while RunnableChain connects templates with models so repeatable product flows can be packaged as reusable units.

Call Example

RunnableChain chain;
chain.setSystemPrompt("你是 Qt 架构顾问。");
chain.setPrompt(PromptTemplate("请分析 {topic} 的实现方案。"));
chain.setModel(model);

ChatReply* reply = chain.invoke({ { "topic", "工具调用审批" } }, this);

Output Parsing

Includes string, JSON, and structured output parsers so model responses can be consumed by Qt application logic.

Capability Details

When the model should return structured data, JsonOutputParser or StructuredOutputParser can validate fields and convert text into QJsonObject.

Call Example

QString error;
StructuredOutputParser parser({ "title", "risk", "action" });

QJsonObject data = parser.parse(modelText, &error);
if (!error.isEmpty()) {
    qWarning() << error;
}

Memory and RAG

ChatMemory stores conversation context, while InMemoryRetriever and SimpleRagChain demonstrate local retrieval augmented generation.

Capability Details

ChatMemory keeps multi-turn messages. SimpleRagChain retrieves local context first, then sends both context and question to the model.

Call Example

InMemoryRetriever retriever;
retriever.setDocuments({
    "AgentKit 支持工具调用、审批和 Trace。",
    "StateGraph 用于状态流程编排。"
});

SimpleRagChain rag;
rag.setRetriever(retriever);
rag.setModel(model);
ChatReply* reply = rag.ask("如何做流程编排？", 2, this);

Tool Calling and Approval

Tool registration, arguments, traces, and permission approval form a complete loop, with confirmation before higher-risk actions such as file writes.

Capability Details

FunctionTool registers local C++ functions as tools, while AgentExecutor handles tool calls, traces, and approval for higher-risk permissions.

Call Example

registry->registerTool(new FunctionTool(
    "query_device_status",
    "查询设备状态",
    schema,
    ToolPermission::ReadOnly,
    [](const QJsonObject& args) {
        return ToolResult{ true, {}, "设备状态正常" };
    },
    registry));

State Workflow

StateGraph supports nodes, conditional edges, loops, checkpoints, and human review for traceable Agent workflows.

Capability Details

StateGraph uses QJsonObject as state. Nodes return partial updates, and normal or conditional edges decide the next step.

Call Example

StateGraph graph;
graph.addNode("step", [](const QJsonObject& state) {
    return QJsonObject{ { "count", state.value("count").toInt() + 1 } };
});
graph.addEdge(StateGraph::start(), "step");
graph.addEdge("step", StateGraph::end());

GraphRunResult result = graph.invoke({ { "count", 0 } });
