+### Registering with an Agent
+
+> **Important:** Defining a tool class in `agents/tools.py` does **not** make it available to an agent automatically. You must explicitly import the tool and add an instance of it to the agent's `tools` list in `agents/<name>/agent.py`.
+
+```python
+# agents/<name>/agent.py
+
+from cogsol.agents import BaseAgent, genconfigs
+from cogsol.prompts import Prompts
+from ..tools import WeatherTool, OrderLookupTool  # Import your tool classes
+
+
+class SupportAgent(BaseAgent):
+    system_prompt = Prompts.load("support.md")
+    generation_config = genconfigs.QA()
+
+    # Each tool must be explicitly listed here as an instance
+    tools = [
+        WeatherTool(),
+        OrderLookupTool(),
+    ]
+```
+
+After updating `agent.py`, regenerate and apply migrations so the agent configuration is synced:
+
+```bash
+python manage.py makemigrations agents
+python manage.py migrate agents

 ## Adding Tools
 
+> **Note:** Adding a tool to your project is a two-step process:
+> 1. **Define** the tool class in `agents/tools.py` (or `agents/searches.py` for retrieval tools).
+> 2. **Register** it in the agent by importing it and adding an instance to the `tools` list in `agents/<name>/agent.py`.
+>
+> Simply defining the tool class is not enough — the agent will not use it until it is explicitly listed in `agent.py`.
+
 ### Step 1: Create a Custom Tool
 
 Edit `agents/tools.py` to add a useful tool. New projects include a commented example block; uncomment it or replace it with your own tool classes.
