# Decision-memo format When surfacing a decision, tradeoff, or interpretation call, never bury it in a status paragraph. Use this four-part memo: 1. **Headline** — one line naming the decision. 2. **Options as concrete A/B examples** — actual code/command snippets side by side when the difference is code; never prose descriptions of the difference. 3. **Recommendation** — with confidence % and the single deciding reason. 4. **Explicit ask + default** — state what happens if the user says nothing.
