useConfigureSuggestions

React hook for configuring chat suggestions

Overview

useConfigureSuggestions is a React hook that registers a suggestions configuration with the CopilotKit core. It supports two modes: static suggestions (a fixed list) and dynamic suggestions (generated by the agent based on instructions).

The configuration is automatically registered on mount and removed on unmount. When the configuration changes, suggestions are reloaded automatically.

Signature

import { useConfigureSuggestions } from "@copilotkit/react-core/v2";

function useConfigureSuggestions(
  config: SuggestionsConfigInput | null | undefined,
  deps?: ReadonlyArray<unknown>,
): void;

Usage

Static Suggestions

function WelcomeSuggestions() {
  useConfigureSuggestions({
    suggestions: [
      { title: "Get started", message: "Help me get started with my project" },
      { title: "Show examples", message: "Show me some example use cases" },
      {
        title: "Documentation",
        message: "Where can I find the documentation?",
      },
    ],
    available: "before-first-message",
  });

  return null;
}

Dynamic Suggestions

function SmartSuggestions() {
  useConfigureSuggestions({
    instructions:
      "Suggest follow-up questions based on the conversation so far. " +
      "Focus on actionable next steps the user might want to take.",
    maxSuggestions: 3,
    minSuggestions: 1,
    available: "after-first-message",
  });

  return null;
}

Dynamic Suggestions with Dependencies

function ContextualSuggestions() {
  const [topic, setTopic] = useState("general");

  useConfigureSuggestions(
    {
      instructions: `Generate suggestions related to the topic: ${topic}`,
      maxSuggestions: 3,
    },
    [topic],
  );

  return (
    <select value={topic} onChange={(e) => setTopic(e.target.value)}>
      <option value="general">General</option>
      <option value="technical">Technical</option>
      <option value="business">Business</option>
    </select>
  );
}

Conditionally Disabling Suggestions

function ConditionalSuggestions({ enabled }: { enabled: boolean }) {
  useConfigureSuggestions(
    enabled
      ? {
          suggestions: [{ title: "Help", message: "I need help" }],
        }
      : null,
  );

  return null;
}

Targeting a Specific Agent

function AgentSpecificSuggestions() {
  useConfigureSuggestions({
    instructions: "Suggest data analysis tasks the user can perform.",
    maxSuggestions: 4,
    providerAgentId: "analyst",
    consumerAgentId: "analyst",
    available: "always",
  });

  return null;
}

Behavior

  • Automatic Registration: The configuration is registered with the core on mount and removed on unmount. This ensures clean lifecycle management.
  • Change Detection: The hook serializes the configuration to JSON for comparison. If the serialized value changes, the old config is removed and the new one is registered, triggering a reload.
  • Dependency Tracking: When a deps array is provided, any change in its values triggers a suggestion reload, even if the serialized config itself has not changed.
  • Config Discrimination: The hook distinguishes between dynamic and static configs by checking for the presence of the instructions property. If instructions is present, it is treated as a dynamic config.
  • Disabled State: Passing null, undefined, or a config with available: "disabled" will remove any previously registered configuration and produce no suggestions.
  • isLoading Normalization: For static suggestions, the isLoading field defaults to false if not explicitly provided.
