The analyst corpus
A strong session usually includes the latest workbook, last month’s board or leadership deck, a metrics dictionary or data dictionary snippet, and any email/PDF context that explains anomalies. Once loaded, you can ask for variance stories, cohort explanations, or a one-page exec brief that points back to the files.
High-ROI prompts for weekly rhythms
- “Explain WoW and MoM moves in sheet Forecast vs Actual; list top 5 drivers.”
- “Draft a stakeholder update in plain language; keep numbers only if present in the workbook.”
- “Build a checklist of open questions before the metrics review.”
- “Reconcile the deck claims against the CSV export; flag mismatches.”
Sandbox analysis when formulas are not enough
Oxygen chat includes spreadsheet tooling and sandbox workflows for heavier cuts — joins, reshapes, and exploratory scripts — without forcing every question through a fragile formula chain. Use it when the ask is “slice this three ways and summarize,” not when you need a audited production pipeline.
From ad-hoc chat to reusable agents
Once a weekly brief format works, promote it to a Studio agent with a fixed outline: headline metrics, drivers, risks, asks. Drop in the new export each Monday. That is how AI becomes operational instead of theatrical.
