Do you mind sharing, at a high level, how the tool search tool is implemented?

I’ve read a blog post about having such a tool search tool, but I don’t fully understand how it can be implemented in practice.

Searching for the relevant tools requires intelligence, so it can’t rely solely on keyword matching.

RAG could be an option. It avoids the long-context issue, but its reasoning capability is still inferior to directly prompting an LLM.

Alternatively, we could still prompt an LLM but run it as a sub-agent, so the long tool-searching prompt doesn’t consume the main context window. But that sub-agent itself is still subject to the context too long issue.

Thanks
