# Specification Quality Checklist: Fiber Middleware Integration with Configuration Management

**Purpose**: Validate specification completeness and quality before proceeding to planning  
**Created**: 2025-11-10  
**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 Assessment

✅ **PASS**: The specification focuses on user value and business outcomes without implementation details. While technical components (Viper, Zap, Redis) are mentioned in the functional requirements, they describe **what capabilities** the system must provide (configuration management, structured logging, token validation) rather than **how to implement** them. The Technical Requirements section appropriately references the project constitution's technology choices.

✅ **PASS**: The specification is written from a business/operations perspective with user stories framed around administrator needs, API consumer expectations, and system reliability outcomes.

✅ **PASS**: All mandatory sections (User Scenarios, Requirements, Success Criteria) are completed with detailed content.

### Requirement Completeness Assessment

✅ **PASS**: No [NEEDS CLARIFICATION] markers present. All requirements are concrete and specific.

✅ **PASS**: All functional requirements are testable with clear expected behaviors (e.g., "detect changes within 5 seconds", "return HTTP 401 with specific error format").

✅ **PASS**: Success criteria include specific measurable metrics:
- Time-based: "within 5 seconds", "within 50ms", "within 100ms"
- Percentage-based: "100% consistency", "100% of HTTP requests"  
- Behavior-based: "automatically rotate when reaching configured size limits"

✅ **PASS**: Success criteria are technology-agnostic, focusing on user/system outcomes (e.g., "System administrators can modify configuration and see it applied" rather than "Viper watches config files").

✅ **PASS**: All user stories include detailed acceptance scenarios in Given-When-Then format.

✅ **PASS**: Edge cases section covers 7 different failure/boundary scenarios with expected behaviors.

✅ **PASS**: Scope is clearly bounded through prioritized user stories (P1, P2, P3) and explicitly states rate limiting is "implemented but disabled by default".

✅ **PASS**: Dependencies identified through Technical Requirements section referencing constitution standards, and implicit dependencies on Redis for token validation.

### Feature Readiness Assessment

✅ **PASS**: Each of the 22 functional requirements maps to acceptance scenarios in user stories and success criteria.

✅ **PASS**: Seven prioritized user stories cover the complete feature set from foundational (configuration, logging) to security (authentication) to optional (rate limiting).

✅ **PASS**: Ten success criteria provide measurable validation for all major functional areas.

✅ **PASS**: Technical Requirements section appropriately references existing project standards rather than introducing new implementation details.

## Overall Assessment

**STATUS**: ✅ **READY FOR PLANNING**

All checklist items pass validation. The specification is complete, testable, and ready for the `/speckit.plan` phase.

## Notes

- The specification successfully balances business requirements with project constitution compliance
- User stories are well-prioritized with clear independent test criteria
- Edge cases demonstrate thorough consideration of failure scenarios
- Success criteria provide clear acceptance thresholds without prescribing implementation approaches
