Example 1: Procrastination Eliminator App (from 阿星AI工作室)

Original Requirement (Vague)

帮我开发一个拖延症消除器网页应用,需要有提醒功能和任务管理功能。
比如可以提醒大家通过拆解步骤完成工作,把大任务拆解为小任务

Translation: Help me develop a procrastination eliminator web app with reminder and task management features. For example, it can remind people to complete work by breaking down steps, decomposing big tasks into small tasks.

Problems:

• Functional description too broad, lacks specific details
• Technical solution standardized, lacks specificity
• No consideration of behavioral psychology factors
• Missing specific interaction design guidance

EARS Transformation

Requirement rewritten using EARS syntax:

1. When a user creates a new task, the system shall guide the user to decompose the large task into executable small task steps

2. When a user sets task timing, the system shall send scheduled reminder notifications

3. When a user completes a sub-task, the system shall update overall task progress and provide positive feedback

4. When a user accesses the application, the system shall display the to-do task list and completion statistics

Domain Theory Identification

Domain: Behavior Psychology, Time Management, Human-Computer Interaction Design

Relevant Mature Theories:

• Getting Things Done (GTD) - David Allen's task management methodology
• Pomodoro Technique - Time segmentation management technique
• Behavior Change Theory - BJ Fogg's Behavior Model (B=MAT)
• Gamification Design Theory - Enhance user engagement through reward mechanisms

Example 4: Password Reset Feature (Security-Focused)

Original Requirement (Vague)

Build me a password reset feature

Problems:

• No specification of reset method (email, SMS, security questions)
• Missing security constraints (rate limiting, token expiration)
• No UX flow defined (how user initiates, confirms reset)
• Lack of error handling requirements

EARS Transformation

1. When user clicks "Forgot Password", the system shall display email input field

2. When user submits valid email, the system shall send password reset link valid for 1 hour

3. When user clicks reset link, the system shall verify token has not expired

4. When token is valid, the system shall display password creation form requiring minimum 12 characters, 1 uppercase, 1 number, 1 special character

5. When user submits new password meeting requirements, the system shall hash password with bcrypt and invalidate reset token

6. When user attempts password reset more than 3 times in 1 hour, the system shall block further attempts for 1 hour

7. If reset token has expired, the system shall display error message and option to request new link

Domain Theories

Domain: Authentication Security, User Experience Design

Relevant Theories:

• Zero Trust Architecture - Never trust input; verify token at each step
• Defense in Depth - Multiple security layers (rate limiting, token expiration, password complexity)
• Progressive Disclosure - Guide user through multi-step flow without overwhelming

Enhanced Prompt

# Role
Senior security engineer and UX designer specializing in authentication systems, with expertise in OWASP security standards and user-friendly security design.

## Skills
- Design secure password reset flows resistant to common attacks (brute force, token leakage)
- Implement cryptographic best practices (bcrypt, secure token generation)
- Apply UX principles to security-sensitive interactions
- Handle edge cases and error states gracefully
- Comply with GDPR and data protection regulations

## Workflows
1. Request initiation - User enters email, client-side validation for format
2. Token generation - Server generates cryptographically random token (256-bit), stores with 1-hour expiration
3. Email delivery - Send reset link via transactional email service with clear instructions
4. Link validation - Verify token exists, not expired, not already used
5. Password creation - Enforce complexity requirements with real-time feedback
6. Password storage - Hash with bcrypt (cost factor 12), invalidate token, log security event
7. Rate limiting - Track attempts by IP and email, implement exponential backoff

## Examples
- **Reset email:** Subject: "Password Reset Request", Body: "Click here to reset your password (link expires in 1 hour): https://example.com/reset?token=abc123..."
- **Password requirements:** "Minimum 12 characters, at least 1 uppercase letter (A-Z), 1 number (0-9), 1 special character (!@#$%)"
- **Error messages:** "This reset link has expired. Please request a new password reset link."
- **Rate limiting:** "Too many reset attempts. Please try again in 59 minutes."

## Formats
Implement the following:
- Backend API endpoints: POST /api/auth/forgot-password, POST /api/auth/reset-password
- Email template (HTML) with reset link and instructions
- Frontend pages: Forgot password form, Reset password form
- Database schema: password_reset_tokens table (token, email, created_at, expires_at, used)
- Security measures: Rate limiting middleware, token hashing in database, HTTPS-only cookies
- Error handling: User-friendly messages, detailed server logs

How to use: Provide this to an AI code assistant or development team. The EARS requirements enable test-driven development, the theories justify security decisions, and the examples provide concrete test cases.

Next steps: Implement the password reset feature using this specification, or iterate with additional security requirements (2FA, account recovery, etc.)
