+## Agent Types Matrix
+
+| Agent Type | Purpose | Tools | Memory |
+|------------|---------|-------|---------|
+| Research | Information gathering | Web, Files, Memory | Long-term |
+| Planning | Task breakdown | Memory, Expert | Short-term |
+| Implementation | Code generation | Files, Git, Expert | Context-based |
+| Math | Mathematical computation | Calculator, Symbolic | Task-specific |
+
+## Communication Protocol
+
+```mermaid
+sequenceDiagram
+    participant C as Client
+    participant A as Agent
+    participant T as Tools
+    participant M as Memory
+
+    C->>A: Submit Task
+    A->>M: Load Context
+    loop Task Execution
+        A->>T: Use Tool
+        T-->>A: Tool Result
+        A->>M: Update Memory
+    end
+    A-->>C: Return Result
+```
+
+## State Management
+
+### Memory Types
+```python
+class MemoryItem:
+    priority: float
+    timestamp: datetime
+    content: str
+    metadata: Dict[str, Any]
+
+class WorkingMemory:
+    short_term: List[MemoryItem]
+    long_term: List[MemoryItem]
+    context: Dict[str, Any]
+```
+
+## Extension Architecture
+
+### Plugin System
+```python
+class AgentPlugin:
+    """Base class for agent plugins"""
+    def initialize(self, agent: BaseAgent) -> None:
+        pass
+    
+    def pre_execute(self, context: Dict[str, Any]) -> None:
+        pass
+    
+    def post_execute(self, result: Any) -> Any:
+        pass
+```
+
+## Error Handling
+
+### Pattern Implementation
+```python
+class AgentError(Exception):
+    """Base class for agent errors"""
+    def __init__(self, message: str, context: Dict[str, Any]):
+        self.context = context
+        super().__init__(message)
+
+async def run_agent_with_retry(
+    agent: BaseAgent,
+    task: str,
+    max_retries: int = 3
+) -> Result:
+    for attempt in range(max_retries):
+        try:
+            return await agent.execute(task)
+        except AgentError as e:
+            if attempt == max_retries - 1:
+                raise
+            await agent.recover(e)
+```
+
+## Implementation Examples
+
+### Creating Custom Agent
+```python
+class CustomAgent(BaseAgent):
+    def setup_tools(self) -> None:
+        self.tools = [
+            CalculatorTool(),
+            MemoryTool(),
+            FileSystemTool()
+        ]
+    
+    async def execute(self, task: str) -> Result:
+        plan = await self.create_plan(task)
+        return await self.execute_plan(plan)
+```
+
+### Memory Integration
+```python
+class MemoryAwareAgent(BaseAgent):
+    async def process_with_memory(
+        self,
+        task: str,
+        context: Optional[Dict] = None
+    ) -> Result:
+        relevant = self.memory.search(task)
+        enhanced_context = {
+            **context,
+            "memory": relevant
+        }
+        return await self.process(task, enhanced_context)
+```

+## Overview
+This document details the specifications and usage of our RESTful API endpoints.
+
+## Authentication
+
+### API Key Authentication
+Include your API key in all requests via the Authorization header:
+```bash
+Authorization: Bearer YOUR_API_KEY
+```
+
+### OAuth 2.0 Endpoints
+
+#### Authorization Request
+```
+GET /oauth/authorize
+```
+Parameters:
+- client_id (required)
+- redirect_uri (required)
+- scope (optional)
+- state (recommended)
+
+#### Token Exchange
+```
+POST /oauth/token
+```
+Parameters:
+- grant_type (required)
+- code (required)
+- client_id (required)
+- client_secret (required)
+- redirect_uri (required)
+
+## Request/Response Standards
+
+### Headers
+Required request headers:
+```
+Content-Type: application/json
+Authorization: Bearer YOUR_API_KEY
+Accept: application/json
+```
+
+### Response Format
+All responses follow this structure:
+```json
+{
+  "status": "success|error",
+  "data": {
+    // Response payload
+  },
+  "meta": {
+    "page": 1,
+    "perPage": 25,
+    "total": 100
+  }
+}
+```
+
+## Rate Limits
+
+### Default Limits
+- 1000 requests per minute per API key
+- 10000 requests per hour per API key
+
+### Headers
+Rate limit information is returned in headers:
+```
+X-RateLimit-Limit: 1000
+X-RateLimit-Remaining: 999
+X-RateLimit-Reset: 1640995200

+API_KEY = 'your_api_key'
+headers = {
+    'Authorization': f'Bearer {API_KEY}',
+    'Content-Type': 'application/json'
+}
+
+# List users
+response = requests.get(
+    'https://api.example.com/v1/users',
+    headers=headers
+)
+
+# Create user
+user_data = {
+    'email': '[email protected]',
+    'name': 'John Doe',
+    'role': 'user'
+}
+response = requests.post(
+    'https://api.example.com/v1/users',
+    headers=headers,
+    json=user_data
+)
+```
+
+### Pagination
+```python
+def fetch_all_users():
+    users = []
+    page = 1

+            'https://api.example.com/v1/users',
+            params={'page': page},
+            headers=headers
+        )
+        data = response.json()
+        
+        if not data['data']:
+            break
+            
+        users.extend(data['data'])
+        page += 1
+    
+    return users
+```
+
+### Error Handling
+```python
+try:
+    response = requests.post(
+        'https://api.example.com/v1/users',
+        headers=headers,
+        json=user_data
+    )
+    response.raise_for_status()
+    user = response.json()['data']
+    
+except requests.exceptions.HTTPError as e:
+    if e.response.status_code == 429:
+        # Handle rate limiting
+        retry_after = int(e.response.headers.get('Retry-After', 60))
+        time.sleep(retry_after)
+    else:
+        # Handle other errors
