Specification Quality Checklist: UnivaPay Card Payment Integration (MVP)

Purpose: Validate specification completeness and quality before proceeding to planning
Created: 2026-08-02
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

• UnivaPay-specific terms (inline form, metadata, webhook, test tokens) are retained as names of the external specification confirmed in UnivaPay’s answers — they are prerequisites, not implementation directives
• Items from the old docs (docs/univaPayment/) — PayPay, bank transfer, automatic store creation, fee-splitting, UnivaPay Widget — are excluded from this MVP scope (see Assumptions)
• Validation result: all items passed on the first iteration
