I can work on this.

@ighoshsubho, thanks again! I'd love to hear what your vision is for how tools could be integrated with Lumos. To be transparent, I haven't actually used the tools before, so I don't necessarily have a goal or vision yet. This issue was originally just a reminder for me to do some research 😄

Anyways, I'm open to hearing from you! There are constraints, considerations, and questions that I'm interested in. For example:

• How are tools invoked?
• How are tools configured?
• How do the tools work offline?
• Are the tools free ($)?
• How do users "build and bring their own tools" outside of LangChainJS's tools?
• How do users share their tools with others?
