"""
define a generic tool class, any tool can be used by the agent.
A tool can be used by deepseek like so:
```<tool name>
<code or query to execute>
```
For example:
```python
print("Hello world")
```
This is then executed by the tool with its own class implementation of execute().
A tool is not just for code tool but also API, internet, etc..
For example a flight API tool could be used like so:
```flight_search
HU787
```
