Ask for Structure
Structure Makes an Answer Checkable
A paragraph of confident prose is hard to audit. You read it, it sounds right, you move on. The same information in a table with one row per item and one column per criterion is a different object: you can scan it, spot the empty cell, notice that two rows contradict each other, and see immediately that it only covered four of the six things you asked about. Weak: "Compare these five suppliers." Strong: "Compare these five suppliers in a table. Columns: supplier, lead time, minimum order, price per unit, one risk, and whether they meet our two-week requirement — yes or no." Structure is not a formatting preference. It is what turns an answer into something you can verify rather than trust.
- Weak: "Compare these five suppliers"
- Strong: names the exact columns, including a yes/no verdict column
- Gaps and contradictions are visible in a table and invisible in prose
- A forced yes/no or number column stops the answer hiding behind hedging
Pick the Shape That Matches the Job
Different jobs want different shapes. Comparisons want tables. Sequences want numbered steps. Decisions want a recommendation first, then the reasoning, then what would change the answer. Data you will process wants a strict format such as JSON or CSV with named fields — and if you ask for that, say "return only the data, no commentary", or you will get a friendly sentence wrapped around it that breaks whatever you paste it into. Recurring documents want a template you supply. The general principle: decide what you will do with the output, then ask for the shape that makes that easy. Reformatting an answer by hand is work you can eliminate in one sentence.
- Comparison → table; process → numbered steps; decision → verdict first, then reasoning
- Machine-readable output → name the fields and say "return only the data, no commentary"
- Recurring work → supply your template and say "fill this in exactly"
- Choose the shape from what you will do next, not from what looks tidy
Build the Checking Into the Format
You can go further and make the format carry your quality controls. Add a column for "confidence: high, medium or low". Add a final section headed "what I could not determine from the material you gave me". Ask for "source: which paragraph of the document this came from" beside each claim. Ask for "assumptions I made" as a separate list. These are not decorative — they concentrate the uncertainty in one place instead of leaving it distributed invisibly through fluent prose. A summary with an honest "not stated in the source" line is far more useful than one that silently filled the gap, and you only get it if you asked for somewhere to put it.
- Add a confidence column and a "not determinable from this material" section
- Ask for a source or paragraph reference beside each factual claim
- Request an explicit "assumptions I made" list — it surfaces the silent ones
- Give uncertainty a home in the format, or it will be smoothed away
