[Feature]: Implement New Agent within Existing Framework

[wiseaidev]

This issue serves as a guide for integrating a new agent into our framework. The initial step involves defining a struct that encapsulates your agent's functionality, incorporating a field of type AgentGPT, which implements the Agent trait.

The next step is to expand the agent's capabilities by introducing any necessary API clients. Following this, you'll implement methods within the defined struct that leverage your API Client type effectively. Have a look at the existing agents for inspirations (e.g. ArchitectGPT):
