Frame a build-or-kill decision with explicit inputs
Lay out the evidence, the constraints, and the commitments so the decision is not driven by sunk cost.
What this prompt helps you do
A recommendation with the evidence weighed, sunk cost named and excluded, and reversal conditions.
When to use it
An initiative is underperforming and the discussion keeps returning to what has already been spent.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Name the sunk cost explicitly and exclude it; unnamed, it dominates the decision while nobody admits it.
How to use this prompt
Replace each placeholder with accurate context. Paste the complete prompt into Claude, review the response critically, resolve important questions, and use it as a considered input to the next decision—not as an unchecked final answer.
