# Specification Quality Checklist: Adapter Shared Infrastructure

**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

## Caching Strategy, Proxy Streaming, Raw Payload (I6, N3, N4)

- [x] US5–US7 acceptance scenarios are testable and unambiguous
- [x] FR-009 through FR-013 are measurable
- [x] SC-005 through SC-007 are technology-agnostic success criteria
- [x] Edge cases for new features (unsupported adapter caching, slow callback, proxy auth) identified
- [x] CacheStrategy defined in core (provider-agnostic), translated by adapters
- [x] OnRawPayload panic isolation specified (catch_unwind)
- [x] ProxyStreamFn reuses AdapterBase for auth

## Notes

- All items pass. Spec is ready for `/speckit.clarify` or `/speckit.plan`.
- I6 (Caching), N3 (Proxy), N4 (Raw Payload) added 2026-03-31: US5–US7, FR-009–FR-013, SC-005–SC-007, tasks T041–T063.
