# Specification Quality Checklist: Model Catalog, Presets & Fallback

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-03-20
**Feature**: [spec.md](../spec.md)

## Content Quality

- [x] No implementation details
- [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
- [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

## Cost Calculation & Capability Introspection (I21, I22)

- [x] US4–US5 acceptance scenarios are testable and unambiguous
- [x] FR-010 through FR-014 are measurable
- [x] SC-006 through SC-009 are technology-agnostic success criteria
- [x] Edge cases for cost calculation (unknown model, missing pricing, provider-specific costs) identified
- [x] Graceful degradation specified (zero cost for unknowns)
- [x] Backward compatibility maintained (Option fields, existing ModelCapabilities reused)

## Notes

- All items pass. Spec is ready for `/speckit.clarify` or `/speckit.plan`.
- I21 (Cost Calculation) and I22 (Capability Introspection) added 2026-03-31: US4–US5, FR-010–FR-014, SC-006–SC-009, tasks T031–T044.
