Deck Refresh

Swaps numbers across a presentation without breaking the formatting or rebuilding slides. You give it a mapping (revenue $485M to $512M, EBITDA $120M to $135M), it finds every instance across text boxes, tables, chart data, and footnotes, then shows you a full change plan before touching anything. The approval gate matters because it flags derived numbers like growth rates that might now be stale. Works in both the PowerPoint add-in and chat. Treats the deck as the source of truth for style, so if your deck writes $485MM and you say $485M, it keeps the MM convention. Built for quarterly refreshes and comp rolls where the structure is right but the numbers moved.

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.

Phase 1 — Get the data

Use ask_user_question to find out how the new numbers are arriving:
