brainstorm-prompt-optimizer

脑暴提示词优化器

将原始想法转化为优化后的提示词，以便用于脑暴工作流（/specs.brainstorm）。

此技能会梳理想法，使其传入 /specs.brainstorm 后，能够产出更完善的功能规格说明，遵循 EARS 语法、正确的验收标准分类，并包含完整的非目标／否定性需求部分。

适用场景

• 用户想在运行 /specs.brainstorm 前优化一个想法
• 用户说“为脑暴准备这个想法”“增强脑暴提示词”
• 用户提出一个简单想法，希望将其整理成更适合脑暴的形式
• 用户询问“把这个准备成脑暴提示词”
• 用户说“imposta per brainstorm”“prepara idea per brainstorm”

不适用场景

• 用户想优化代码或性能（使用相应技能）
• 用户想进行通用提示词工程（使用 prompt-engineering 技能）
• 用户想分析现有提示词
• 用户要求直接执行某项任务
• 用户想修复 Bug 或修改现有行为 → 转交给 specs.change-spec

工作原理

仅输出优化后的提示词——不要提供分析、报告或建议。

此工作流会将原始想法转化为结构化提示词，使其用于 /specs.brainstorm 时能够产出更完善的功能规格说明。

工作流

阶段 1：识别项目上下文

检查项目文件以了解环境：

• CLAUDE.md → 项目约定
• docs/specs/architecture.md → 现有架构约束
• docs/specs/ontology.md → 现有领域术语

技术栈检测：

• package.json → Node.js/TypeScript/React
• pom.xml / build.gradle → Java/Spring Boot
• requirements.txt / pyproject.toml → Python

阶段 2：分析想法

解析原始想法，识别：

1. 核心操作：需要构建／创建什么（例如，“添加身份验证”“创建搜索功能”）
2. 目标领域：系统中的哪些部分会受到影响
3. 隐含范围：哪些内容自然包含在内，哪些不包含
4. 用户视角：谁会从此功能中受益
5. 业务价值：此功能为何重要

阶段 3：确定范围大小

估算复杂度，帮助 /specs.brainstorm：

• 小型：单个用户故事、1-3 个实体、简单流程 → 3-8 个任务
• 中型：2-4 个用户故事、4-8 个实体 → 8-15 个任务
• 大型：5 个以上用户故事、9 个以上实体 → 可能需要拆分（提醒用户）

阶段 4：构建优化后的提示词

构建结构化提示词，包含以下组件（与 /specs.brainstorm 模板一致）：

# [Core Action] — [Target Domain]

## Problem Statement
[What problem does this solve? Who has it?]

## Core Feature
[What should the system do? Focus on behavior, not implementation]

## Target Users
[Who will use this? What's their goal?]

## User Flows
1. [Primary flow from user perspective]
2. [Alternative flows if applicable]

## Data Requirements
- [What data the feature needs to work with]
- [Any data relationships]

## Success Criteria
- [IMP] [Testable criterion that requires code/implementation]

## EARS Syntax Reference

Use EARS (Easy Approach to Requirements Syntax) for requirements:

| Form | Pattern | Example |
|------|---------|---------|
| **Event-driven** | `WHEN <event> THEN the system SHALL <action>` | `WHEN the user clicks "Submit" THEN the system SHALL validate the form data` |
| **State-driven** | `WHEN <system state> THEN the system SHALL <action>` | `WHEN the session expires THEN the system SHALL clear user data` |
| **Generic** | `The system SHALL <action>` | `The system SHALL encrypt all stored passwords with bcrypt` |
| **Feature** | `IF <feature> THEN the system SHALL <action>` | `IF multi-factor auth is enabled THEN the system SHALL require second factor` |
| **Negative** | `IF <unwanted condition> THEN the system SHALL NOT <action>` | `IF SQL input detected THEN the system SHALL reject with 400` |

Mandatory keywords: **SHALL**, **WILL**, **MAY**
Forbidden words: "robust", "intuitive", "fast", "scalable", "efficient", "user-friendly"

---

## Acceptance Criteria Taxonomy

Every success criterion MUST be tagged:

| Tag | Meaning | Generates Tasks? |
|-----|---------|------------------|
| `[IMP]` | Requires new code, configuration, or explicit behavior | **YES** |
| `[SEF]` | Natural automatic consequence of an `[IMP]` criterion | NO (verify in e2e) |
| `[EXT]` | Verified by external tools or user observation | NO (e2e checkpoint) |

**60% Rule**: At least 60% of criteria should be `[IMP]`.

示例

示例 1：简单想法 → 优化后

输入：

Add user authentication

输出：

# Add User Authentication — Authentication Layer

## Problem Statement
Users cannot securely access the system. They need a way to prove their identity and access their personalized content.

## Core Feature
The system SHALL provide email/password authentication that allows users to:
- Register with a valid email address and secure password
- Log in with registered credentials
- Maintain an authenticated session across requests
- Log out to terminate their session

## Target Users
- **Primary**: End users who need to access personalized features
- **Secondary**: Administrators who manage user accounts

## User Flows
1. **Registration**: User enters email → receives confirmation → sets password → account created
2. **Login**: User enters credentials → validated → session established → redirected to dashboard
3. **Logout**: User clicks logout → session terminated → redirected to login page

## Data Requirements
- User entity: email, hashed_password, created_at, updated_at
- Session entity: user_id, token, expiration

## Success Criteria
- [IMP] Users can register with email/password
- [IMP] Users can log in with valid credentials
- [IMP] Invalid credentials show generic error message
- [IMP] Users can log out
- [IMP] Session persists across page navigation
- [IMP] Expired sessions require re-login

## Non-Goals

示例 2：模糊想法 → 结构化

输入：

Better search for products

输出：

# Improve Product Search — Product Discovery

## Problem Statement
Users cannot find products they are looking for using the current search. Results are not relevant, don't match user intent, and sorting is not useful.

## Core Feature
The system SHALL provide enhanced product search that allows users to:
- Search products by name, description, and category
- Receive results ranked by relevance to search terms
- Filter results by category, price range, and availability
- Sort results by relevance, price, or newest

## Target Users
- **Primary**: Shoppers looking for specific products
- **Secondary**: Browsers exploring product catalog

## User Flows
1. **Direct Search**: User enters search terms → results displayed → user selects product
2. **Filtered Search**: User enters terms → applies filters → refined results → user selects product
3. **Empty Results**: User enters terms → no results → suggestion displayed

## Search Behavior
- Minimum 2 characters to trigger search
- Partial word matching for product names
- Search across: product name, description, category name, tags
- Results limited to 50 per page with pagination

## Filtering Options
- Category: single or multiple selection
- Price range: min/max with validation
- Availability: in-stock only toggle

## Sorting Options
- Relevance (default): based on search term match score
- Price: low-to-high or high-to-low
- Newest: by creation date descending

## Success Criteria
- [IMP] Search returns products matching the query terms
- [IMP] Search supports partial word matching
- [IMP] Category filter limits results to selected category
- [IMP] Price range filter shows products within min/max bounds
- [IMP] Results can be sorted by relevance, price, or date
- [IMP] Pagination allows navigation through large result sets
- [IMP] Empty search shows appropriate message with suggestions

## Non-Goals
- **Autocomplete**: Not included in this specification

输入：

Implement Redis caching for API responses

输出：

# Implement API Response Caching — Performance Optimization

## Problem Statement
The API is slow for frequently requested data. Repeated requests for the same resources consume unnecessary server resources and increase response times for users.

## Core Feature
The system SHALL cache frequently accessed API responses to reduce response times and server load:
- Cache GET requests for defined intervals
- Return cached responses when data hasn't changed
- Invalidate cache when underlying data changes
- Provide cache statistics for monitoring

## Target Users
- **Primary**: API consumers (frontend applications, mobile apps)
- **Secondary**: System administrators monitoring performance

## Cache Behavior
- Cache key based on request URL and parameters
- Default TTL: 5 minutes (configurable per endpoint)
- Cache stores: response body, status code, headers
- Cache miss: fetch from source, store, return

## Invalidation Rules
- Cache invalidated when source data is modified via POST/PUT/PATCH/DELETE
- Manual invalidation available via admin endpoint
- Bulk invalidation by cache key pattern

## Success Criteria
- [IMP] Cached requests return within 50ms
- [IMP] Cache hit rate visible in metrics
- [IMP] Manual cache invalidation works
- [IMP] Automatic invalidation on data changes
- [IMP] Cache can be disabled per request via header
- [SEF] Cache reduces database load for repeated requests
- [EXT] Response time improvement measurable via APM

## Non-Goals
- **Distributed Cache**: Single Redis instance only
- **Cache Warming**: Not included
- **Cache Partitioning**: Not included
- **Multi-Tenant Isolation**: Not included in this specification

## Negative Requirements
- REQ-NR001: The system SHALL NOT cache responses containing user-specific data
- REQ-NR002: The system SHALL NOT serve stale cache beyond configured TTL
- REQ-NR003: The system SHALL NOT expose cache internals in API responses
- REQ-NR004: IF cache connection fails THEN the system SHALL fall back to direct database access without error
