Haven't gotten to all of them, but this: - Updates some of the tools notebooks to actually instantiate a tool (many just show a 'utility' rather than a tool. More changes to come in separate PR) - Move the `Tool` and decorator definitions to `langchain/tools/base.py` (but still export from `langchain.agents`) - Add scene explain to the load_tools() function - Add unit tests for public apis for the langchain.tools and langchain.agents modules
