Overview
The main idea behind the npm create hedera-agent CLI tool is to scaffold Next.js applications that come pre-configured with the Hedera AI Agent Kit and WalletConnect integration. This means you can kickstart your Hedera-based AI agent projects with a single command. Think of it as your personal assistant for setting up the initial project structure, so you can focus on the fun part: building amazing AI agents.
Problem Statement
Let's face it, setting up a new project can be a real drag. There are so many things to configure, and if you're not careful, you can easily get lost in the details. The current process for bootstrapping Hedera AI agent applications involves a lot of manual configuration, which can be time-consuming and error-prone. Hereās a breakdown of the challenges:
Next.js Setup with Proper Runtime Configurations
Setting up Next.js might seem straightforward, but getting the runtime configurations right for a Hedera-based application can be tricky. You need to ensure that the application is properly configured to interact with the Hedera network, which involves setting up the correct environment variables and dependencies. This initial setup can take a significant amount of time, especially if you're new to Next.js or Hedera.
Hedera Agent Kit Integration
Integrating the Hedera Agent Kit manually involves installing the necessary packages, configuring the kit, and ensuring that it works seamlessly with your application. This process requires a good understanding of the kit's architecture and how it interacts with the Hedera network. For developers who are just starting out, this can be a steep learning curve.
WalletConnect Wallet Integration
WalletConnect is crucial for enabling users to securely sign transactions in your application. However, integrating WalletConnect involves setting up the necessary dependencies, configuring the WalletConnect client, and handling the connection and signing processes. This can be a complex task, especially when dealing with different wallet providers and ensuring a smooth user experience.
Multiple AI Model Provider Support
Many AI agent applications need to support multiple AI model providers, such as OpenAI, Google AI, and others. Configuring your application to work with different providers involves setting up the necessary APIs, handling authentication, and managing the different request and response formats. This adds another layer of complexity to the setup process.
Environment Variable Management
Properly managing environment variables is essential for security and flexibility. You need to ensure that sensitive information, such as API keys and account credentials, is stored securely and that your application can easily switch between different environments (e.g., development, staging, production). Manually managing environment variables can be cumbersome and error-prone.
TypeScript and Modern Tooling Setup
Using TypeScript and modern tooling can greatly improve the development experience, but setting everything up from scratch can be a challenge. You need to configure TypeScript, set up linting and formatting tools, and ensure that everything works well together. This can take a significant amount of time and effort, especially if you're not familiar with the latest best practices.
Goals
The npm create hedera-agent CLI tool aims to address these challenges by providing a streamlined way to bootstrap Hedera AI agent applications. Let's look at the specific goals it's designed to achieve.
G1: Interactive CLI that Prompts for Configuration and Generates Ready-to-Use .env Files
The first goal is to create an interactive CLI that guides developers through the configuration process. This CLI should prompt users for the necessary information, such as project name, AI model provider, and Hedera network details. Based on the user's input, the CLI should generate ready-to-use .env files with the appropriate environment variables. This interactive approach makes it easy for developers to set up their projects correctly, even if they're not familiar with all the details.
The interactive nature of the CLI is crucial because it simplifies the initial setup phase. Instead of manually creating and configuring files, developers are guided through a series of prompts that ensure all necessary configurations are in place. The CLI should handle the complexities of setting up environment variables, making the process more accessible to developers of all skill levels. By generating ready-to-use .env files, the CLI ensures that the application can run smoothly right from the start.
This goal also extends to providing clear and concise prompts that are easy to understand. The CLI should offer helpful descriptions and examples, making the configuration process intuitive. Additionally, the CLI should validate user input to prevent common errors and ensure that the generated .env files are correctly formatted. This attention to detail significantly reduces the chances of misconfiguration and streamlines the development workflow.
G2: Generated Next.js App Boots Successfully with Functional Chat Interface
A key goal is to ensure that the generated Next.js application boots successfully and includes a functional chat interface. This means that after running the CLI, developers should be able to start their application without encountering errors and immediately begin testing the chat functionality. The chat interface should be pre-configured to interact with the Hedera network and the chosen AI model provider.
Having a functional chat interface out of the box is a significant advantage because it allows developers to quickly see their AI agent in action. This immediate feedback is invaluable for iterating on the design and functionality of the agent. The CLI should handle the complexities of setting up the chat interface, including integrating the necessary UI components and connecting them to the backend services. This reduces the initial setup time and allows developers to focus on building the core logic of their AI agent.
The successful booting of the Next.js application is also a critical aspect of this goal. The CLI should ensure that all necessary dependencies are installed, and the application is configured correctly to run in different environments. This includes setting up the appropriate build scripts and ensuring that the application can be deployed easily. By addressing these technical details, the CLI provides a solid foundation for building robust and scalable Hedera-based AI agent applications.
G3: Human-in-the-Loop Mode Integrates WalletConnect for Transaction Signing
For applications that require human approval for certain actions, the CLI should support a human-in-the-loop mode that integrates WalletConnect. This allows users to review and sign transactions before they are submitted to the Hedera network. The CLI should handle the complexities of setting up WalletConnect, including connecting to different wallet providers and handling the transaction signing process.
Integrating WalletConnect for transaction signing is essential for applications that prioritize security and user control. The CLI should make it easy to set up WalletConnect by providing the necessary configurations and handling the integration with the chat interface. This includes implementing the UI components for connecting to a wallet and displaying transaction details. By handling these details, the CLI simplifies the process of building secure and user-friendly applications.
The human-in-the-loop mode is particularly important for sensitive transactions that require user authorization. The CLI should ensure that the transaction signing process is smooth and intuitive, guiding users through the steps needed to review and approve transactions. This involves displaying clear and concise information about the transaction and providing a secure mechanism for signing. By focusing on the user experience, the CLI helps developers build applications that are both secure and easy to use.
G4: Autonomous Mode Executes Transactions Directly Using Operator Credentials
In some cases, applications may need to execute transactions autonomously, without requiring human approval. For these scenarios, the CLI should support an autonomous mode that uses operator credentials to sign transactions directly. The CLI should provide secure mechanisms for storing and managing operator credentials, ensuring that they are protected from unauthorized access.
The autonomous mode is crucial for applications that need to perform tasks automatically, such as scheduled transactions or automated responses. The CLI should handle the complexities of setting up operator credentials, including securely storing them and using them to sign transactions. This involves implementing secure storage mechanisms and ensuring that the credentials are used only when necessary. By handling these security considerations, the CLI helps developers build applications that are both efficient and secure.
The CLI should also provide clear guidance on how to configure and use the autonomous mode, including best practices for managing operator credentials. This ensures that developers can use the autonomous mode safely and effectively. By focusing on security and usability, the CLI helps developers build applications that can operate autonomously while maintaining a high level of security.
