# Specification Quality Checklist: TOON Format Integration

**Purpose**: Validate specification completeness and quality before proceeding to planning  
**Created**: 2026-02-23  
**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 (4 open questions documented in separate section)
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (describe outcomes, not implementations)
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified (7 edge cases documented)
- [x] Scope is clearly bounded (out-of-scope section included)
- [x] Dependencies and assumptions identified (6 assumptions, 2 dependency groups)

## Feature Readiness

- [x] All functional requirements have clear acceptance criteria (21 FRs with acceptance scenarios)
- [x] User scenarios cover primary flows (5 user stories, prioritized P1-P4)
- [x] Feature meets measurable outcomes defined in Success Criteria (10 success criteria)
- [x] No implementation details leak into specification

## Additional Validation

- [x] User stories are independently testable (each story has "Independent Test" section)
- [x] User stories are prioritized (P1-P4 priorities assigned with rationale)
- [x] Observability requirements are comprehensive (FR-014 through FR-018)
- [x] Fallback strategy is documented (FR-010 through FR-013)
- [x] Risk analysis is thorough (5 risks with mitigation and contingency)
- [x] Open questions are clearly stated (4 questions with suggested approaches)

## Notes

✅ **All validation items pass**

This specification is ready for technical planning (`/speckit.plan`). Key strengths:

1. **Comprehensive observability**: FR-014 through FR-018 ensure we can measure token savings
2. **Graceful degradation**: FR-010 through FR-013 ensure TOON failures don't break requests
3. **Prioritized stories**: P1 (tool results) delivers 80% of value; P4 (MCP output) is nice-to-have
4. **Clear risks and mitigations**: Beta library risk addressed with vendoring option
5. **Technology-agnostic success criteria**: All SC items describe measurable user/system outcomes

No clarifications needed from user. Proceed directly to planning phase.
