Add a SQL agent for interacting with SQL Databases and JSON Agent for interacting with large JSON blobs (#1150)
This PR adds * `ZeroShotAgent.as_sql_agent`, which returns an agent for interacting with a sql database. This builds off of `SQLDatabaseChain`. The main advantages are 1) answering general questions about the db, 2) access to a tool for double checking queries, and 3) recovering from errors * `ZeroShotAgent.as_json_agent` which returns an agent for interacting with json blobs. * Several examples in notebooks --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>searx-doc

Your goal is to return a final answer by interacting with the JSON.

|
||||
Only use the below tools. Only use the information returned by the below tools to construct your final answer.
|
||||
Do not make up any information that is not contained in the JSON.
|
||||
Your input to the tools should be in the form of `data["key"][0]` where `data` is the JSON blob you are interacting with, and the syntax used is Python.
|
||||
You should only use keys that you know for a fact exist. You must validate that a key exists by seeing it previously when calling `json_spec_list_keys`.
|
||||
If you have not seen a key in one of those responses, you cannot use it.
|
||||
You should only add one key at a time to the path. You cannot add multiple keys at once.
|
||||
If you encounter a "KeyError", go back to the previous key, look at the available keys, and try again.
|
||||
|
||||
If the question does not seem to be related to the JSON, just return "I don't know" as the answer.
|
||||
Always begin your interaction with the `json_spec_list_keys` tool with input "data" to see what keys exist in the JSON.
|
||||
|
||||
Note that sometimes the value at a given path is large. In this case, you will get an error "Value is a large dictionary, should explore its keys directly".
|
||||
In this case, you should ALWAYS follow up by using the `json_spec_list_keys` tool to see what keys exist at that path.

Do not simply refer the user to the JSON or a section of the JSON, as this is not a valid answer. Keep digging until you find the answer and explicitly return it.
