Requirement

[UDS] Write user stories and requirements that satisfy the INVEST criteria. Use when: turning a feature idea into a user story, defining testable acceptance criteria, checking a backlog item for quality. Not for: full specification documents with design and delta operations — use /sdd; deciding whether the idea is right at all — use /brainstorm. Keywords: requirement, user story, INVEST, acceptance criteria, backlog refinement, 需求, 使用者故事, 驗收條件.
