Overview

LLM::Transformer is the superclass for message transformers in llm.rb.

A transformer is bound to a context and rewrites a single message before it is sent to the provider. Each subclass implements a different transformation: it takes a message in #call and returns a message. Null is a no-op (the default).

A transformer may mutate the message in place or return a new one. Either way, the returned message is what gets sent.
