# Specification Quality Checklist: Python Library with Universal LLM Support

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2025-12-19
**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

### Content Quality Check
- **No implementation details**: PASS - Specification focuses on capabilities and user outcomes without mentioning specific technologies (Python, LiteLLM, Pydantic are mentioned only in context of what the library does, not how)
- **User value focus**: PASS - Each user story explains why the capability matters to developers
- **Stakeholder readability**: PASS - Written in plain language describing what users can do
- **Mandatory sections**: PASS - All required sections present and populated

### Requirement Completeness Check
- **No clarification markers**: PASS - All requirements are fully specified with reasonable defaults documented in Assumptions section
- **Testable requirements**: PASS - Each FR uses "MUST" with specific, verifiable capabilities
- **Measurable success criteria**: PASS - All SC items have quantifiable metrics (5 minutes, 10 providers, 100%, 95%, etc.)
- **Technology-agnostic criteria**: PASS - Success criteria describe outcomes, not implementations
- **Acceptance scenarios**: PASS - 8 user stories with 25+ Given/When/Then scenarios
- **Edge cases**: PASS - 5 edge cases identified with expected behaviors
- **Scope bounded**: PASS - "Out of Scope" section clearly defines exclusions
- **Assumptions documented**: PASS - 6 assumptions clearly stated

### Feature Readiness Check
- **Acceptance criteria coverage**: PASS - All 14 functional requirements trace to user story acceptance scenarios
- **Primary flow coverage**: PASS - 8 user stories covering all workflow phases and interfaces
- **Success criteria alignment**: PASS - Each success criterion maps to testable outcomes
- **No implementation leaks**: PASS - Requirements describe what, not how

## Notes

- Specification is complete and ready for `/speckit.clarify` or `/speckit.plan`
- All validation items pass - no updates required
- 8 prioritized user stories (3 P1, 3 P2, 2 P3) provide clear implementation ordering
- 14 functional requirements with clear MUST statements
- 10 measurable success criteria with quantifiable targets
