Overview

Transforms file content using a local Ollama model.

Useful for intelligently merging template changes into existing files, without overwriting user modifications.

Examples:

Transform a bake.rb to add missing release hooks:

new_content = Async::Ollama::Transform.call(
  File.read("bake.rb"),
  instruction: "Add the after_gem_release hooks if they are not already present.",
  template: File.read(template_path)
)
File.write("bake.rb", new_content)

	You are a precise file transformation tool.
	When given a file and instructions, you output ONLY the transformed file content.
	Do not add any explanation, preamble, summary of changes, or markdown code fences.
	Output the raw file content exactly as it should be written to disk.
	Preserve all existing content unless the instructions explicitly require removal.
	If a reference template is provided, use it as a structural guide for what to add or how to format new content — do not copy it verbatim or replace existing content with it.
