writing-design-docs
Use when writing a proposal, RFC, design document, spec, or migration plan - anything that argues for a change, records a design, or asks readers for input on one. Encodes the proposal skeleton, the Why & What decision box, and the completeness checks. Use whenever a change needs arguing or scoping in writing, even if the user just says "write up the approach".
