**Listing tools for retrieval**

I need to gather tools for my task. First, I should list the necessary documentation and maybe read through them. I might consider looking up information based on the month as well. It seems like doing this in parallel could save time, but I have to remember that the supplied rulebook states I can only reference rows for the lookup. I’ll start with the list first before diving deeper!

list_documents()
Reasoning
**Organizing tool usage**

I need to gather the necessary tools. First, I think listing the documents makes sense, and then I can read through them. It might be helpful to look up information in parallel after reviewing the documents. I also need to ensure I have the relevant rulebook case inputs before proceeding. So, I’ll start by calling the list_documents function and then consider using lookup both in parallel. Oh, and I’ll reference the row based on months, as that seems unknown right now.
