# Specification Quality Checklist: Undo/Redo

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-03-26
**Feature**: [spec.md](../spec.md)

## Content Quality

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

## Requirement Completeness

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

## Feature Readiness

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

## Notes

- All items pass. The spec references "memento pattern" and "localStorage" — these are architectural intent from the issue itself, not implementation leakage. The spec describes *what* (snapshot-based history, persisted to local storage) not *how* (no code structure, no framework APIs).
- The "Assumptions" section documents the localStorage sizing assumption and the dependency on #15 being resolved.
