+
+## 📦 Installation
+
+```bash

+pip install agentscope-runtime
+
+# Install Claude Agent SDK (when available)
+pip install anthropic-agent-sdk
+
+# Set API key
+export ANTHROPIC_API_KEY=your_api_key_here
+```
+
+## 🎯 Quick Examples
+
+### Example 1: Basic Agent with Memory
+
+```python
+from agentscope_runtime.engine import AgentApp
+from agentscope_runtime.adapters.claude import (
+    ClaudeAgentMemoryAdapter,
+    ClaudeAgentStateAdapter,
+    ClaudeAgentMemory,
+    ClaudeAgentState,
+)
+
+agent_app = AgentApp(app_name="ClaudeAgent")
+
+@agent_app.init
+async def init_func(self):
+    self.memory = ClaudeAgentMemory()
+    self.state = ClaudeAgentState()
+
+@agent_app.query(framework="claude")
+async def query_func(self, msgs, request, **kwargs):
+    # Create adapters
+    memory = ClaudeAgentMemoryAdapter(
+        user_id=request.user_id,
+        session_id=request.session_id,
+        memory=self.memory,
+    )
+
+    state = ClaudeAgentStateAdapter(
+        user_id=request.user_id,
+        session_id=request.session_id,
+        state_storage=self.state,
+    )
+
+    # Your Claude SDK integration here
+    # ...
+
+if __name__ == "__main__":
+    agent_app.run(host="127.0.0.1", port=8090)
+```
+
+### Example 2: Agent with Tools
+
+```python
+from agentscope_runtime.tools.base import Tool
+from agentscope_runtime.adapters.claude.tool import (
+    create_claude_mcp_server_config,
+    get_allowed_tool_names,
+)
+from pydantic import BaseModel, Field
+
+# Define custom tool
+class CalculatorInput(BaseModel):
+    operation: str = Field(..., description="Operation: add, subtract, etc.")
+    a: float = Field(..., description="First number")
+    b: float = Field(..., description="Second number")
+
+class CalculatorOutput(BaseModel):
+    result: float = Field(..., description="Result")
+
+class CalculatorTool(Tool[CalculatorInput, CalculatorOutput]):
+    name = "calculator"
+    description = "Perform arithmetic operations"
+
+    async def _arun(self, args: CalculatorInput, **kwargs):
+        ops = {"add": lambda a, b: a + b, "subtract": lambda a, b: a - b}
+        result = ops[args.operation](args.a, args.b)
+        return CalculatorOutput(result=result)
+
+# Create MCP server config
+calculator = CalculatorTool()
+mcp_config = create_claude_mcp_server_config(
+    [calculator],
+    server_name="my-tools",
+    server_version="1.0.0",
+)
+
+# Get allowed tool names
+allowed_tools = get_allowed_tool_names("my-tools", [calculator])
+# Returns: ["mcp__my-tools__calculator"]
+
+# Use with Claude SDK:
+# from claude_agent_sdk import create_sdk_mcp_server, ClaudeAgentOptions
+#
+# tool_callables = [t["callable"] for t in mcp_config["tools"]]
+# mcp_server = create_sdk_mcp_server(
+#     name=mcp_config["server_name"],
+#     version=mcp_config["server_version"],
+#     tools=tool_callables,
+# )
+#
+# options = ClaudeAgentOptions(
+#     mcp_servers={"my-tools": mcp_server},
+#     allowed_tools=allowed_tools,
+# )
+```
+
+## 🧪 Running the Demos
+
+### Basic Demo (Without Tools)
+
+```bash
+python examples/integrations/claude/claude_agent_sdk_demo.py
+```
+
+Access at: `http://127.0.0.1:8090`
+
+Endpoints:
+- `POST /agent/query` - Send query to agent
+- `GET /api/memory/{user_id}/{session_id}` - Get conversation history
+- `GET /api/state/{user_id}/{session_id}` - Get session state
+
+### Tools Demo (With Calculator & Weather)
+
+```bash
+python examples/integrations/claude/claude_with_tools_demo.py
+```
+
+Access at: `http://127.0.0.1:8091`
+
+Additional endpoints:
+- `GET /api/tools` - List available tools
+- `GET /api/tools/{tool_name}` - Get tool info
+- `POST /api/tools/{tool_name}/execute` - Execute tool directly
+
+Test tool execution:
+```bash
+curl -X POST http://127.0.0.1:8091/api/tools/calculator/execute \
+  -H "Content-Type: application/json" \
+  -d '{"operation": "add", "a": 5, "b": 3}'
+```
+
+## 📚 Core Concepts
+
+### 1. Message Conversion
+
+Automatically converts between Claude SDK and Runtime formats:
+
+```python
+from agentscope_runtime.adapters.claude import (
+    claude_msg_to_message,
+    message_to_claude_msg,
+)
+
+# Claude → Runtime
+runtime_msgs = claude_msg_to_message(claude_message)
+
+# Runtime → Claude
+claude_msg = message_to_claude_msg(runtime_message)
+```
+
+### 2. Memory Management
+
+Store and retrieve conversation history:
+
+```python
+memory = ClaudeAgentMemoryAdapter(
+    user_id="user123",
+    session_id="sess456",
+)
+
+# Add message
+memory.add_message({"type": "user", "message": {...}})
+
+# Get history
+history = memory.get_history()
+
+# Clear session
+memory.clear()
+```
+
+### 3. State Persistence
+
+Save and restore agent state:
+
+```python
+state = ClaudeAgentStateAdapter(
+    user_id="user123",
+    session_id="sess456",
+)
+
+# Save state
+await state.save_state({
+    "claude_session_id": "sess_abc",
+    "context": "...",
+})
+
+# Load state
+saved = await state.load_state()
+```
+
+### 4. Tool Integration
+
+Convert Runtime tools to Claude SDK format:
+
+```python
+from agentscope_runtime.adapters.claude.tool import claude_tool_adapter
+
+# Single tool
+adapter = claude_tool_adapter(my_tool)
+metadata = adapter.get_tool_metadata()
+tool_func = adapter.get_callable()
+
+# Multiple tools
+from agentscope_runtime.adapters.claude.tool import create_claude_toolkit
+
+adapters = create_claude_toolkit([tool1, tool2, tool3])
+```
+
+## 🔍 Message Type Mapping
+
+| Claude SDK | Runtime | Description |
+|------------|---------|-------------|
+| `text` block | `MessageType.MESSAGE` | Regular text |
+| `tool_use` block | `MessageType.PLUGIN_CALL` | Tool invocation |
+| `tool_result` block | `MessageType.PLUGIN_CALL_OUTPUT` | Tool result |
+
+## 🧪 Testing
+
+```bash
+# Run all adapter tests
+pytest tests/test_claude_agent_adapter.py -v
+
+# Run tool adapter tests
+pytest tests/test_claude_tool_adapter.py -v
+```

+## 🆘 Common Issues
+
+### 1. Claude SDK Not Installed
+
+```
+ModuleNotFoundError: No module named 'claude_agent_sdk'
+```
+
+**Solution**: The demos work in simulation mode without Claude SDK. To use actual Claude SDK:
+```bash
+pip install anthropic-agent-sdk
+export ANTHROPIC_API_KEY=your_key
+```
+
+### 2. Pydantic Import Error
+
+```
+ModuleNotFoundError: No module named 'pydantic'
+```
+
+**Solution**:
+```bash
+pip install pydantic
+```
+
+### 3. Memory/State Not Persisting
+
+**Issue**: Data lost between restarts
+
+**Solution**: The default implementations use in-memory storage. For persistence, extend the adapters to use external storage (Redis, database, etc.)
+
+## 💡 Tips
+
+1. **Session Management**: Use unique `session_id` for each conversation thread
+
+2. **Tool Names**: Claude SDK requires format `mcp__{server}__{tool_name}`. Use `get_allowed_tool_names()` helper
+
+3. **Error Handling**: Tool callables automatically catch errors and return proper format
+
+4. **Schema Generation**: Schemas are auto-generated from Pydantic models - use `Field(description=...)` for better tool descriptions
