  14. Max Iterations (number, optional)

    • Label: Max Iterations

    • Description: Maximum number of iterations for the agent

​
Outputs

  • output: The result of the agent’s execution, including:

    • Content: The main response text

    • Used Tools: List of tools used during execution

    • Source Documents: Any relevant source documents

    • Artifacts: Additional data or files generated

​
Functionality

  1. Tool Execution: Can use various tools to accomplish tasks.

  2. State Management: Updates and maintains state across interactions.

  3. Approval Workflow: Optional approval process before tool execution.

  4. Dynamic Prompting: Uses system and human prompts with variable substitution.

  5. Multi-modal Support: Can process and generate responses with image content.

  6. Iteration Control: Limits the number of execution cycles.

  7. Flexible Configuration: Supports both UI-based and code-based configurations.

​
Use Cases

  • Complex multi-step conversations

  • Research and information gathering tasks

  • Decision-making processes requiring multiple tools

  • Workflows needing human oversight (with approval feature)

  • Dynamic state-based interactions in chatbots or virtual assistants

​
Notes

  • Requires proper setup of predecessor nodes and tools.

  • Careful configuration of prompts and state management is crucial for effective operation.

  • Can be computationally intensive, especially with multiple tools and iterations.
