# Specification Quality Checklist: Editable Block Labels in Parameter Panel

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-01-16
**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 Notes

### Content Quality Review
- ✅ Spec focuses on WHAT users need (editable label field) and WHY (accessibility, panel-based workflows)
- ✅ No mention of React, TypeScript, Python implementation patterns, or component names
- ✅ Written in plain language suitable for product managers and stakeholders
- ✅ All mandatory sections present: User Scenarios, Requirements, Success Criteria

### Requirement Completeness Review
- ✅ Zero [NEEDS CLARIFICATION] markers - all requirements are fully specified
- ✅ Every functional requirement is testable (e.g., FR-003: "MUST update block's label" can be verified via Python object inspection)
- ✅ Success criteria include specific metrics (50ms persistence, 100ms canvas update, 100% block type coverage)
- ✅ Success criteria avoid implementation details (no mention of "traitlet sync", "React state", or "component props")
- ✅ All 3 user stories have detailed acceptance scenarios (4-5 scenarios each)
- ✅ Edge cases cover boundary conditions (empty labels, long names, concurrent edits, special characters, panel closure)
- ✅ Scope is bounded to Parameter panel label editing (excludes double-click canvas editing, excludes Sum blocks)
- ✅ Dependencies implicit but clear (requires existing traitlet sync, Parameter panel infrastructure, Block label attribute)

### Feature Readiness Review
- ✅ FR-001 through FR-011 map directly to acceptance scenarios in US1, US2, US3
- ✅ US1 (Replace Type Display) + US2 (Edit Label) + US3 (Independence from Visibility) cover complete user journey
- ✅ Each user story is independently testable and delivers value standalone
- ✅ SC-001 through SC-005 align with functional requirements and provide measurable validation
- ✅ No implementation leakage detected (e.g., no mention of "onUpdate callback", "useState hook", or "widget.py")

### Priority Rationalization
- US1 (P1): Foundation - must exist before editing can occur
- US2 (P1): Core value - actual editing functionality
- US3 (P2): Data integrity - ensures consistency but depends on US1/US2 working first

## Result

**Status**: ✅ PASSED - Specification is ready for planning phase

All checklist items validated successfully. The specification is complete, unambiguous, testable, and ready for `/speckit.plan`.
