# Specification Quality Checklist: Agent Struct & Public API

**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 (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

## Dynamic Model Swap & Wait for Idle (I20, N15)

- [x] US6–US7 acceptance scenarios are testable and unambiguous
- [x] FR-015 through FR-020 are measurable
- [x] SC-010 through SC-012 are technology-agnostic success criteria
- [x] Edge cases for new features (mid-run swap, subscriber wait, same-model swap) identified
- [x] Backward compatibility maintained (`set_model()` unchanged, `set_model_with_stream()` is additive)
- [x] Both features already implemented — tasks verify and extend existing behavior

## Notes

- All items pass. Spec is ready for `/speckit.clarify` or `/speckit.plan`.
- I20 (Dynamic model swap) and N15 (Wait for idle) added 2026-03-31: US6–US7, FR-015–FR-020, SC-010–SC-012, tasks T079–T093.
