Design specs before building

Define requirements, design, and task breakdown pre-implementation

Multi-module architecture-heavy changes requiring explicit design before coding.

• · product request scope

• · requirements.md (EARS)
• · design.md (architecture)
• · tasks.md (checklist)

Change scope medium-to-large or acceptance criteria unclear

Skipping user confirmation, vague acceptance criteria, jumping to code

• · EARS-style acceptance criteria
• · User confirmation gates
• · Requirement→design→task traceability
