[🔗](https://github.com/georgeguimaraes/arcana/blob/main/lib/arcana/pipeline/rewriter/llm.ex#L1)

LLM-based query rewriter.

Uses the configured LLM to transform conversational input into clear
search queries. This is the default rewriter used by `Pipeline.rewrite/2`.

## Usage

    # With Arcana.Pipeline (uses ctx.llm automatically)
    ctx
    |> Pipeline.rewrite()
    |> Pipeline.search()
    |> Pipeline.answer()

    # Directly
    {:ok, rewritten} = Arcana.Pipeline.Rewriter.LLM.rewrite(
      "Hey, can you tell me about Elixir?",
      llm: &my_llm/1
    )
