Cumulative Diff
A unified view of all changes accumulated across a sandbox session, showing what would happen if you Promoted. Helpful for review before commit.
What it is
Cumulative Diff renders `git diff <default>...sandbox/<name>` with green/red/gray line coloring and a `+N / -N lines across M files` summary. It shows everything that's been done across all prompts in the session — the integrated picture you'd be Promoting.
When you would use it
Always review the Cumulative Diff before Promoting a sandbox session. It's the safety check before merge.
Common operations
- Reviewing total sandbox impact before Promote
- Catching unintended changes that accumulated across multiple prompts
