Create your tools
Now let's do actual coding, tools are the reason why y made this package, are custom code triggers by the chain and let the LLM model do the RAG base on that function output,
create a Class that extend from Garissman\LaraChain\Structures\Classes\FunctionContract,
like Garissman\LaraChain\Functions\ExampleTool
The Description is the most important part of the function, it tells the LLM when to trigger the tool call and start asking for parameter
The properties are the parameter of your tool, it tells the LLM what are the parameter, also has a description as well, very important.
TODO
- make Function command and use RAG for the description.
- make Agent command and use RAG for the context.
- Knowledge Table.
- Tests, nothing new!!!
