Assembly

LM-Kit.NET.dll

ConditionalNode(string, Func<NodeContext, CancellationToken, Task<string>>, IReadOnlyDictionary<string, IOrchestrationNode>, IOrchestrationNode)

Initializes a new ConditionalNode.

public ConditionalNode(string name, Func<NodeContext, CancellationToken, Task<string>> selector, IReadOnlyDictionary<string, IOrchestrationNode> branches, IOrchestrationNode defaultBranch = null)

Parameters

name string

Stable trace name for this node.

selector Func<NodeContext, CancellationToken, Task<string>>

Async function that returns the route name for the current context.

branches IReadOnlyDictionary<string, IOrchestrationNode>

Map of route name to node.

defaultBranch IOrchestrationNode

Optional fallback when the selector returns an unknown route.

Examples

Route a request to the technical or business expert based on a keyword:

using LMKit.Model;
using LMKit.Agents;
using LMKit.Agents.Orchestration.Nodes;
using var model = LM.LoadFromModelID("qwen3:8b");
var techExpert = Agent.CreateBuilder(model).WithPersona("TechExpert").Build();
var bizExpert = Agent.CreateBuilder(model).WithPersona("BizExpert").Build();
var router = new ConditionalNode("route",
ctx => ctx.Input.Contains("api", StringComparison.OrdinalIgnoreCase) ? "tech" : "biz",
new Dictionary<string, IOrchestrationNode>
{
["tech"] = new AgentNode("tech", techExpert),
["biz"] = new AgentNode("biz", bizExpert)
});
var orchestrator = new GraphOrchestrator(router);
var result = await orchestrator.ExecuteAsync("How do I version a public API?");

Parameters

name string

selector Func<NodeContext, string>

branches IReadOnlyDictionary<string, IOrchestrationNode>

defaultBranch IOrchestrationNode
