You have a question about your market and no good way to answer it that does not eat two days. This turns the question into a structured brief with sources you can open, in about an hour, and it tells you plainly where the evidence is thin instead of filling the gap with confident noise.
Use a model with web access for this one. Write your real question into the first line, in the words you would use talking to a colleague, then run it. Expect to go one round of follow-ups before the brief is worth keeping.
You are producing a market brief for me. My question is: [write your actual question here, as specifically as you can] Work in this order and show me each step. First, restate my question as the three sub-questions that actually have to be answered. If my question is too vague to answer well, tell me so and give me the sharper version before continuing. Then answer each sub-question. For every claim you make, give the source and the date. If a number is older than two years, say so next to it. If you cannot source a claim, write "unsourced" beside it rather than dropping it or dressing it up. Then give me a section called "What I could not establish", listing what is genuinely unknown or contested, and what it would take to find out. Finish with the three things I should do differently based on this, and the one thing that would change your answer if it turned out to be false. Do not smooth over gaps. A short brief with honest holes is more useful to me than a complete-looking one I cannot trust.
The brief is the input to something else: a deck, a positioning call, a decision about where to spend next quarter. Hand the finished brief to the deck workflow and the slides assemble from evidence rather than from memory.
