Purpose: Validate specification completeness and quality before proceeding to planning
Created: 2026-07-31
Feature: spec.md

Content Quality

• No implementation details (languages, frameworks, APIs)
• Focused on user value and business needs
• Written for non-technical stakeholders
• All mandatory sections completed

Requirement Completeness

• No [NEEDS CLARIFICATION] markers remain
• Requirements are testable and unambiguous
• Success criteria are measurable
• Success criteria are technology-agnostic (no implementation details)
• All acceptance scenarios are defined
• Edge cases are identified
• Scope is clearly bounded
• Dependencies and assumptions identified

Feature Readiness

• All functional requirements have clear acceptance criteria
• User scenarios cover primary flows
• Feature meets measurable outcomes defined in Success Criteria
• No implementation details leak into specification

Notes

• Items marked incomplete require spec updates before /speckit-clarify or /speckit-plan
• All items pass on first validation pass; no [NEEDS CLARIFICATION] markers were needed because the feature request already specified concrete timing (day 0/3/6/7), status names, and exact email copy.
