# Specification Quality Checklist: Sum Block Quadrant Configuration

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-01-14
**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

## Validation Results

**Status**: ✅ PASSED - All validation items complete

### Content Quality Assessment
- Specification focuses on WHAT (quadrant-based configuration) and WHY (simplify interaction, remove text editing)
- No technology-specific details (TypeScript, React, SVG implementation details avoided)
- Written in plain language suitable for product managers and designers
- All mandatory sections (User Scenarios, Requirements, Success Criteria) are complete

### Requirement Completeness Assessment
- No [NEEDS CLARIFICATION] markers present
- All 10 functional requirements are specific and testable
- Success criteria include measurable outcomes (100% click accuracy, identical functional results, first-attempt success)
- Success criteria avoid implementation details (focus on user-observable behavior)
- Acceptance scenarios defined for both P1 and P2 user stories (8 scenarios total)
- Edge cases identified: rapid double-clicks, boundary clicks, minimum dimensions, connection cleanup
- Scope clearly bounded: Sum block configuration only, removal of properties panel
- Dependencies implicit (existing block resizing, port regeneration, connection cleanup features)

### Feature Readiness Assessment
- Each functional requirement maps to acceptance scenarios in user stories
- User scenarios cover core functionality (P1) and scaling behavior (P2)
- Success criteria measurable: 100% click accuracy, identical results, first-attempt success
- No leakage of implementation details (no mention of React, event handlers, coordinate math, etc.)

## Notes

All validation items pass. Specification is ready to proceed to `/speckit.plan`.

Key strengths:
- Clear prioritization (P1 for core functionality, P2 for scaling)
- Comprehensive edge case coverage
- Well-defined geometric constraints (oval boundary, quadrant detection)
- Backward compatibility consideration (identical to current text-based editing)
