Decision memo generator using a pre-mortem and reversibility test

The prompt
Help me write a one-page decision memo for the following choice: decision_description.
Structure the memo exactly like this:
1. Decision statement: one sentence, unambiguous.
2. Options considered: list 2-4 real alternatives, including "do nothing."
3. Reversibility: is this a one-way or two-way door decision, and what would it cost to reverse it?
4. Pre-mortem: assume it's 6 months from now and this decision was a mistake, write 3 concrete reasons why it failed.
5. Recommendation: state the recommended option and the single strongest reason for it.
6. What would change my mind: name the specific piece of evidence that would make me reconsider.
Use only the information I give you here: context_and_constraints. If information is missing to fill a section, say so explicitly rather than inventing it, and ask me a targeted question instead.

Example output
A one-page memo on whether to hire a contractor vs. a full-time employee. Decision statement is one clean sentence. Options list three: contractor, full-time hire, do nothing and redistribute work. Reversibility notes the contractor route is a two-way door (easy to end), full-time hire is closer to one-way given severance and morale cost. Pre-mortem lists three failure modes including "contractor's context leaves with them at project end." Recommendation picks the contractor route with the reasoning tied to current revenue uncertainty. Closes with "I would change my mind if the pipeline signs two more contracts in the next 30 days."
