Business Outcome

A research report whose style actually matches the decision it's meant to support, instead of a one-size-fits-all output.

Workflow Overview

Pick whichever of these AI tools you have — they're alternatives, not a sequence.

Word

Copilot

Claude

Copilot works differently from the others: with a paid Microsoft 365 Copilot license it's built right into the app above, no copy-pasting needed. Without a license, use it the same way as ChatGPT or Claude — in its own chat window.

Step 1: Know what kind of report you actually needWord

Name the actual audience and what's riding on it before opening the Researcher agent — a Slack-update-style internal note tolerates more rough edges than something going in front of the board, and that distinction is what step 2's mode choice should be based on, not habit.

Step 2: Match the mode to the needCopilotClaude

Auto lets the system decide; Claude mode favors more nuanced writing; Critique has GPT's draft refined by Claude; Model Council has GPT and Claude's outputs judged by a third model for the highest-stakes reports.

Prompt idea:

Research the regulatory risk of expanding into the EU market. Use Model Council mode given this is going to the board — I want the most reconciled, highest-confidence version of the answer.

Step 3: Compare the report against what the mode promisesWord

If you picked Model Council for a high-stakes decision, check that the report actually reflects reconciled reasoning, not just longer output.

Step 4: Default to Auto unless you have a specific reason not toCopilot

Auto is the right choice most of the time — reach for a specific mode only when the stakes or nuance genuinely warrant it.

Check the work

Confirm the chosen mode was actually worth the extra time/cost for this specific report's stakes.
Spot-check a claim or two regardless of which mode was used — no mode eliminates the need to verify.
For board-level reports, have someone with subject expertise review before it's presented.

Expected Outcome

A research report generated in the reasoning mode best suited to the task — nuanced prose, adversarially refined, or multi-model reconciled.

AI is the right call here

This workflow isn't really asking whether to use AI — it's about calibrating how much AI rigor a report's stakes actually warrant, which is exactly the kind of judgment step 4 says to apply rather than defaulting to the heaviest mode every time.
