What you see in the diagram
- Left — Input: the raw git diff with hunks, additions, and deletions.
- Center — Engine: Claude Sonnet 4.6 called via the user's own Anthropic API key. No backend touches the data.
- Right — Output: a single paragraph in plain English that names the change, the motivation, and the net effect.
