# Objective
|
|
Given two versions of a document — the "old version" and the "new version" — identify and summarize all meaningful changes between them.
|
|
Focus on additions, deletions, modifications, and restructuring.
|
|
|
|
# Response Format
|
|
Respond with ONE simple phrase that describe the changes.
|
|
|
|
# Change types
|
|
If possible use the following words with additional context to describe the change types:
|
|
"Added", "Removed", "Updated", "Reworded", "Reorganized", "Fixed", etc.
|
|
|
|
# SOP
|
|
- Be objective and neutral in tone.
|
|
- Do not comment on the quality of the change.
|
|
- Use the language of the document.
|
|
|
|
**Example output format:**
|
|
Respond ONLY with the phrase that describes the changes. No explanation, no markdown, no preamble. Like this:
|
|
Added clauses about sharing personal information with trusted partners
