 ### 9. Identity Propagation & Context
 
-- Enforce User Context Propagation: 
-        Require agents to pass the user's original authentication token (e.g., JWT) to any backend tool or API.
-- Validate at the Source: 
-        Ensure backend services validate the user's identity and permissions, preventing the agent from acting as a privileged "super-user".
-- Maintain Audit Trails: 
-        Log all agent actions with the associated user identity to ensure non-repudiation and clear accountability.

 - Telling the database: This request is coming from User, only show him his own data.

-Implementation: Passing User Identity to AI Tools (Python/FastAPI)
 ```Python
 from fastapi import Header, HTTPException
+
 async def secure_ai_tool(data: dict, authorization: str = Header(None)):
     """
     Ensures the AI Agent acts as a passthrough for the user's identity.
     """
     # 1. Extract and validate the HUMAN user's identity from the bearer token
-    user = verify_jwt(authorization) 
+    user = verify_jwt(authorization)
     if not user:
         raise HTTPException(status_code=401, detail="Valid user context required")
     # 2. Perform the action using the specific human user's permissions
     return await db.execute_action(user_id=user.id, **data)
 ```

 ## Do's and Don'ts
-
 **Do:**
 
 - Apply least privilege to all agent tools and permissions.
