I use Tidewave which is a package for my Elixir app, and it allows the LLM to get access to some internals of my app. For example, Tidewave exposes tools to inspect the database schema, internal hex documentation for packages, introspection to see what functions are available on a module, etc.

While I’m not “vibe” coding, it is nice to be able to ask human language questions and have the LLM query the database to answer questions. Or while working on a feature, I can ask it to delete all the test records I created, etc. I can do that in a repl myself, but it’s sometimes a nice shortcut.

Note, this only runs in dev, so it’s not querying my production database or anything.

Basically, they can be a way to expose additional data or tools to the LLM.
