 Rusty, Efficient, and Agentic LLM Client Library
 
-`llm-worker-rs` is a Rust library designed for building robust and efficient LLM applications. It unifies interactions with multiple LLM providers (Anthropic, Gemini, OpenAI, Ollama) under a single abstraction, with type-safe state management, efficient context caching, and a powerful event-driven architecture.
+`llm-worker` is a Rust library for building autonomous LLM-powered systems. Define tools, register hooks, and let the Worker handle the agentic loop — tool calls are executed automatically until the task completes.
+
+## Features
+
+- Autonomous Execution: The `Worker` manages the full request-response-tool cycle. You provide tools and input; it loops until done.
+- Multi-Provider Support: Unified interface for Anthropic, Gemini, OpenAI, and Ollama.
+- Tool System: Define tools as async functions. The Worker automatically parses LLM tool calls, executes them in parallel, and feeds results back.
+- Hook System: Intercept execution flow with `before_tool_call`, `after_tool_call`, and `on_turn_end` hooks for validation, logging, or self-correction.
+- Event-Driven Streaming: Subscribe to real-time events (text deltas, tool calls, usage) for responsive UIs.
+- Cache-Aware State Management: Type-state pattern (`Mutable` → `Locked`) ensures KV cache efficiency by protecting the conversation prefix.
+
+## Quick Start
+
+```rust
+use llm_worker::{Worker, Message};
+
+// Create a Worker with your LLM client
+let mut worker = Worker::new(client)
+    .system_prompt("You are a helpful assistant.");
+
+// Register tools (optional)
+worker.register_tool(SearchTool::new());
+worker.register_tool(CalculatorTool::new());
+
+// Run — the Worker handles tool calls automatically
+let history = worker.run("What is 2+2?").await?;
+```
