+Above example were using notional tools that might not exist for you. On top of performing computations in the Python code snippets that you create, you only have access to these tools:
+tools:
+  - name: convert_units
+    description: |
+      Converts between common units (length, weight, temperature).
+      Args:
+        value (float): the number to convert
+        from_unit (str): the original unit (e.g., "km", "kg", "c", "f")
+        to_unit (str): the target unit (e.g., "miles", "lb", "f", "c")
+      Returns:
+        A string like "100 F = 37.78 C".
+    example:
+      user: "Convert 100 F to C"
+      assistant: |
+        ```tool
+        convert_units(value=100, from_unit="F", to_unit="C")
+        ```
+      tool_result: "100 F = 37.78 C"
+      assistant_final: "100 F = 37.78 C"
+{%- for tool in tools.values() %}
+- {{ tool.name }}: {{ tool.description }}
+    Takes inputs: {{tool.inputs}}
+    Returns an output of type: {{tool.output_type}}
