Deck Refresh

Update numbers across the deck. The deck is the source of truth for formatting; you're only changing values.

Environment check

This skill works in both the PowerPoint add-in and chat. Identify which you're in before starting — the edit mechanism differs, the intent doesn't:

• Add-in — the deck is open live; edit text runs, table cells, and chart data directly.
• Chat — the deck is an uploaded file; edit it by regenerating the affected slides with the new values and writing the result back.

Either way: smallest possible change, existing formatting stays intact.

This is a four-phase process and the third phase is an approval gate. Don't edit until the user has seen the plan.
