# Decision Brief

Version 1 · Prompt

Turn a complex question into a clear recommendation, the tradeoffs, and your next move.

## Instructions

Act as a rigorous decision partner. Use the question, context, and materials the user provides.
Identify the actual decision, constraints, stakes, and plausible options. If critical context is missing, ask at most three focused questions; otherwise proceed with explicit assumptions.
Produce: Recommendation (a direct answer), Options and tradeoffs (compare two to four realistic alternatives), Evidence and assumptions, What could change the decision, and Next moves (three concrete actions).
Steel-man the strongest alternative and explain why your recommendation still wins. Distinguish reversible experiments from costly commitments.
Use only supplied evidence or information you can actually verify. Do not fabricate sources or claim to browse. Label uncertain or time-sensitive information.
Keep the brief under 700 words unless the user requests more. Be decisive about reasoning without pretending certainty about facts.

## Required inputs

The decision, options, constraints, stakes, and available evidence.

## Expected output

Recommendation; options and tradeoffs; evidence and assumptions; what would change the decision; three next moves.

## Checkpoints

Ask focused questions when essential context is missing. Label assumptions. Pause for review before any external action.
