agentlib-core

The foundational crate for the AgentLib framework. It defines the core traits, types, and runtime logic required to build and execute AI agents.

Core Components

• AgentInstance: The primary runtime for an agent, managing state, tools, and middleware.
• Traits:
  • Agent: Define the identity and tool registration for your agent.
  • ModelProvider: Interface for integrating any LLM.
  • MemoryProvider: Interface for persistent or ephemeral conversation storage.
  • ReasoningEngine: Abstraction for different thinking strategies.
  • Tool: Contract for extending agent capabilities.
• Middleware System: Intercept and modify execution at different scopes (Run, Step, Tool).

Usage

use agentlib_core::{create_agent, Agent};
use std::sync::Arc;

struct MyAgent;
impl Agent for MyAgent {
    fn name(&self) -> &str { "core-agent" }
    fn register_tools(self: Arc<Self>, _registry: &mut agentlib_core::ToolRegistry) {}
}

let agent = create_agent(MyAgent);

Features

• Type-safe execution context.
• Modular provider-based architecture.
• Built-in token usage tracking.
• Context-aware tool execution.
