What is software-design-doc?
Draft, review, and update Software Design Descriptions using an IEEE 1016-2009-inspired structure with explicit architecture/views/elements formalization and output structure validation. Use this whenever a user asks to write an SDD, assess SDD quality/completeness, align design docs to IEEE 1016 concepts, map PRD requirements to design, produce architecture/interface/data design sections, generate a gap report with remediation actions, perform SDD review-only gap analysis, or update an SDD after architecture changes.
