### Problem

When configuring different agents or databases, it might not be clear if things are setup correctly or not or if further troubleshooting is needed. e.g. you're trying to use the Macro agent with a Snowflake database: does a `.env` file exist? is the `MACRO_API_KEY` configured? is it valid? are the snowflake variables configured? do they connect to the database? do they have the necessary permissions?

### Solution

Have some method to determine if things are in a good-to-go state, similar to the function that [`dbt debug`](https://docs.getdbt.com/reference/commands/debug) performs.
