Agent Class

[Unshure]

Description:

Create the main Agent class that integrates model providers, tools, and stubbed agent loop processing. Implement both streaming and non-streaming interfaces for agent interaction.

Work Required:

• Implement Agent class constructor that takes model_provider, messages, tools, and system_prompt
• Add ToolRegistry integration to Agent class for managing loaded tools
• Register tools passed during initialization into the Agent's ToolRegistry
• Create AgentResult interface with stop_reason and latest message
• Implement async invoke method that returns AgentResult using the agentic loop
• Implement async stream method that returns stream of events from agent loop with final AgentResult
• Add messages as editable class attribute for conversation state management
• Add proper error handling and propagation from agentic loop
• Create unit tests for both invoke and stream methods
• Create integration test that tests complete Agent workflow with real model provider and tools
• Consider async initialization

Exit Criteria:

A working Agent class that supports both streaming and non-streaming interfaces, properly integrates with agentic loop for model and tool coordination, manages conversation state, and passes both unit and integration tests.
