+# Implement Tool Management for Dynamic Agents
+
+I will implement a system to manage "Tools" (Function Calls) and associate them with Dynamic Agents, allowing the frontend to easily configure which tools an agent can use.
+
+## 1. Database Schema Expansion
+I will create two new tables in PostgreSQL:
+*   `tools`: Stores reusable tool definitions (templates).
+    *   `tool_id`: `SERIAL PRIMARY KEY`
+    *   `name`: `VARCHAR` (Unique, e.g., "get_weather")
+    *   `description`: `TEXT` (For LLM understanding)
+    *   `parameters`: `JSONB` (JSON Schema for arguments)
+    *   `created_at`: `TIMESTAMP`
+*   `agent_tools`: Maps agents to tools (Many-to-Many).
+    *   `agent_card_id`: `INTEGER` (FK)
+    *   `tool_id`: `INTEGER` (FK)
+    *   `config`: `JSONB` (Optional, for agent-specific tool config if needed)
+
+## 2. API Implementation (`main.py`)
+
+### Pydantic Models
+*   `ToolCreate`: Validation for creating new tool definitions.
+*   `ToolResponse`: API response format.
+*   `AgentToolAssignment`: For linking tools to agents.
+
+### New Endpoints
+*   **Tool Management (CRUD)**:
+    *   `POST /tools/`: Create a new tool definition.
+    *   `GET /tools/`: List all available tools.
+    *   `PUT /tools/{tool_id}`: Update a tool.
+    *   `DELETE /tools/{tool_id}`: Delete a tool.
+*   **Agent Tool Association**:
+    *   `POST /agent/{card_id}/tools`: Assign a list of tools to an agent.
+    *   `GET /agent/{card_id}/tools`: Get all tools assigned to an agent.
+    *   `DELETE /agent/{card_id}/tools/{tool_id}`: Remove a tool from an agent.
+
+### Update Existing Logic
+*   **Modify `GET /dynamic_agent/{card_id}`**:
+    *   Update the query to automatically fetch and include the list of associated tools in the agent details response. This ensures the frontend gets everything in one call.
+
+## 3. Verification
+*   Create a "Weather Query" tool definition.
+*   Assign it to a Dynamic Agent.
+*   Verify the agent details endpoint returns the tool info correctly.
