Spec Writing

使用范围与安全规则

本 Skill 只用于“业务需求说明与验收标准写作”场景，围绕用户当前提供或明确授权处理的材料完成任务。功能目标：Execute this skill should be used when the user asks about "writing 当用户需要处理相关业务场景时使用。

• 默认先在回复中交付分析、方案、草稿、代码建议或检查清单，不主动读取任务范围外的文件、账号和数据。
• 信息不足时先标记缺口并向用户确认，不用猜测内容填补事实、数字、姓名、结论或权限。
• 需要联网检索或调用接口时，先说明访问目标、拟发送的数据和用途并取得用户明确同意；只访问用户指定或公开合法来源，不绕过登录、付费墙、验证码、访问控制或平台限制。
• 不要求用户在对话里粘贴密码、Cookie、Token、API Key 或私钥；凭据仅用于用户指定的对应官方服务，不回显、不记录、不写入交付物，也不转发到无关地址。

Overview

Spec Writing provides guidance on authoring effective specs.md files that drive the Sprint plugin's autonomous development workflow. A well-written specification determines the quality of agent output by clearly defining goals, scope boundaries, and testing requirements.

Prerequisites

• Sprint plugin installed (/plugin install sprint)
• Project onboarding completed via /sprint:setup (creates project-goals.md and project-map.md)
• Sprint directory created via /sprint:new (generates .claude/sprint/[N]/specs.md)
• Understanding of the sprint phase lifecycle (see the sprint-workflow skill)

Instructions

1. Open the generated specs.md file at .claude/sprint/[N]/specs.md and define a concise goal statement at the top. State what the sprint delivers in one sentence (e.g., "Add user authentication with email/password login").
2. Define explicit scope boundaries using In Scope and Out of Scope sections. List specific features, endpoints, or components in each. Agents only implement what appears in scope; ambiguity leads to drift.
3. Add the Testing section to control which testing agents run and how. Configure three settings as documented in ${CLAUDE_SKILL_DIR}/references/testing-configuration.md:
   - QA: required | optional | skip -- Controls API and unit test execution
   - UI Testing: required | optional | skip -- Controls browser-based E2E tests
   - UI Testing Mode: automated | manual -- Auto-run or user-driven testing
4. Set QA to required for new API endpoints, business logic changes, and data validation rules. Set QA to skip for frontend-only changes, documentation updates, or configuration changes.
5. Set UI Testing to required for user-facing features, form submissions, and navigation flows. Choose automated mode for regression testing and standard CRUD flows; choose manual mode for complex interactions, visual verification, or exploratory testing.
6. Keep specifications minimal but precise. The architect expands high-level specs into detailed implementation files (backend-specs.md, frontend-specs.md, api-contract.md). Over-specifying implementation details in specs.md constrains the architect unnecessarily.
7. For iterative sprints, review status.md from the previous iteration. Remove completed items from specs and add any new requirements or bug fixes discovered during testing.

Output

• A complete specs.md file with goal, scope (in/out), and testing configuration
• Clear scope boundaries that prevent agent drift during implementation
• Testing configuration that selects appropriate QA and UI testing agents
• Iteratively refined specs where completed work is removed and remaining work is focused

Error Handling

Examples

Minimal but effective spec:

# Sprint 1: User Authentication

## Goal
Add user authentication with email/password login

## Scope
### In Scope
- Registration endpoint (POST /auth/register)
- Login endpoint (POST /auth/login)
- JWT token generation and validation
- Password hashing with bcrypt

### Out of Scope
- OAuth providers (Google, GitHub)
- Password reset flow
- Email verification

## Testing
- QA: required
- UI Testing: required
- UI Testing Mode: automated

Frontend-only sprint (no QA needed):

# Sprint 3: Dashboard Redesign

## Goal
Redesign the admin dashboard with responsive layout

## Scope
### In Scope
- Responsive grid layout for dashboard widgets
- Dark mode toggle
- Mobile navigation drawer

### Out of Scope
- New API endpoints
- Database changes
- Authentication changes

## Testing
- QA: skip
- UI Testing: required
- UI Testing Mode: manual
