# lib/ai_client/middleware.rb

# TODO: As concurrently designed the middleware must
#       be set before an instance of AiClient is created.
#       Any `use` commands for middleware made after
#       the instance is created will not be available
#       to that instance.
#       Change this so that middleware can be added
#       and removed from an existing client.
