  * The output format is intended to be as easy as possible to process
  * by the Large Language Model (LLM) like Claude from Anthropic.
- * The format follows these principles:
- * 1. Changes are shown character by character for precise tracking
- * 2. Spaces are marked explicitly in change descriptions with [-␣-] and {+␣+}
- * 3. Changes include minimal necessary context
- * 4. Line additions and removals follow a consistent format

  * Test cases are using various formats, like Markdown or HTML, however the difference
  * logic and produced description should be format agnostic by principle.
