M365 cross-app collaboration

Use this skill to coordinate work across Excel, PowerPoint, Word, and Outlook within a single, continuous conversation context, so changes in one artifact can be reflected consistently in others.

Instructions

1) Establish the cross-app objective

• Ask what outcome the user wants (e.g., “an exec-ready deck + a memo + the supporting spreadsheet + a draft email”).
• Confirm which files are open (or should be opened) in Excel/PowerPoint/Word/Outlook.

2) Keep a shared set of assumptions

• Maintain a short list of key assumptions (inputs, definitions, constraints).
• When an assumption changes in Excel, re-check dependent content in the deck and memo.

3) Treat each app as the right tool for the job

• Excel: calculations, scenario inputs, coverage/financial models, tables.
• PowerPoint: charts and narrative slides.
• Word: narrative memo, structured write-up.
• Outlook: inbox triage, reply drafting, calendar invites.
