Example Applications

This section shows you practical examples that demonstrate how to use the Standards Agent Kit in real-world scenarios. All example code is available in the standards-agent-kit/examples/ directory.

LangChain Agent Demo​

A complete example showing how to build an interactive agent with all available tools.

Source Code:
examples/langchain-demo.ts

What You'll Learn:

  • Setting up a complete LangChain agent with all HCS-10 tools
  • Configuring conversation memory and prompt templates
  • Handling both outgoing and incoming connections
  • Building an interactive chat interface for agent testing

Key Components:

  • Full setup with all tools: RegisterAgentTool, FindRegistrationsTool, InitiateConnectionTool, etc.
  • Background connection monitoring with ConnectionTool
  • Properly configured agent executor with memory and system prompts
  • Interactive chat loop for testing the agent's capabilities

Running The Demo:

# 1. Make sure your .env file is set up with credentials
# 2. Build the project
npm run build

# 3. Start the demo
npm run langchain-demo

Command-Line Interface Demo​

A menu-driven application that lets you interact with HCS-10 functionality directly, without using LangChain.

Source Code:
examples/cli-demo.ts

What You'll Learn:

  • Direct usage of the HCS10Client methods
  • How to manage agent registration manually
  • Explicit connection monitoring and management
  • Manual message sending and checking

Key Features:

  • Interactive menu system for selecting operations
  • Direct client method calls showing the underlying API
  • Manual state tracking with OpenConvaiState
  • Connection topic management
  • Message sending and receiving without LangChain

Running The Demo:

# 1. Make sure your .env file is set up with credentials
# 2. Build the project
npm run build

# 3. Start the demo
npm run cli-demo

Utility Functions​

Helper code used by both demos for common operations.

Source Code:
examples/utils.ts

What's Included:

  • Environment variable loading and validation
  • .env file update functions used by RegisterAgentTool
  • HBAR balance checking utilities
  • Common helper functions used across examples

Note: This file isn't meant to be run directly, but contains reusable code that supports the demo applications.
