# Requirements Clarity Plugin
## Overview
This Claude Code plugin automatically detects vague requirements and transforms them into crystal-clear Product Requirements Documents (PRDs) through systematic clarification.
## Installation
```bash
/plugin install requirements-clarity
```
Or add to your `.clauderc`:
```json
{
"plugins": {
"requirements-clarity": {
"enabled": true
}
}
}
```
## How It Works
### Automatic Activation
The plugin activates when Claude detects:
1. **Vague Feature Requests**
```
User: "add login feature"
User: "implement payment system"
User: "create user dashboard"
```
2. **Missing Technical Details**
- No technology stack mentioned
- No architecture or constraints specified
- No integration points identified
3. **Incomplete Specifications**
- No acceptance criteria
- No success metrics
- No edge cases or error handling
4. **Ambiguous Scope**
- Unclear boundaries ("user management" - what exactly?)
- No distinction between MVP and future features
### Clarification Process
```
User: "I want to implement a user login feature"
Claude detects vague requirement
Auto-activates requirements-clarity agent
Initial assessment: 35/100 clarity score
Round 1: Ask 2-3 targeted questions
User responds
Score update: 35 → 72
Round 2: Continue clarifying gaps
User responds
Score update: 72 → 93 ✓ (≥90 threshold)
Generate PRD files:
- ./.claude/specs/user-login/prd.md
- ./.claude/specs/user-login/clarification-log.md
```
## Scoring System (100 points)
| Dimension | Points | Criteria |
|-----------|--------|----------|
| **Functional Clarity** | 30 | Clear inputs/outputs (10), User interaction (10), Success criteria (10) |
| **Technical Specificity** | 25 | Tech stack (8), Integration points (8), Constraints (9) |
| **Implementation Completeness** | 25 | Edge cases (8), Error handling (9), Data validation (8) |
| **Business Context** | 20 | Problem statement (7), Target users (7), Success metrics (6) |
**Threshold**: ≥ 90 points required before PRD generation
## Output Structure
### 1. Clarification Log
`./.claude/specs/{feature-name}/clarification-log.md`
Documents the entire clarification conversation:
- Original requirement
- Each round of questions and answers
- Score progression
- Final assessment breakdown
### 2. Product Requirements Document
`./.claude/specs/{feature-name}/prd.md`
Structured PRD with four main sections:
#### Requirements Description
- Background: Business problem, target users, value proposition
- Feature Overview: Core functionality, boundaries, user scenarios
- Detailed Requirements: Inputs/outputs, interactions, data, edge cases
#### Design Decisions
- Technical Approach: Architecture, components, data storage, APIs
- Constraints: Performance, compatibility, security, scalability
- Risk Assessment: Technical, dependency, timeline risks
#### Acceptance Criteria
- Functional: Checklistable feature requirements
- Quality Standards: Code quality, testing, performance, security
- User Acceptance: UX, documentation, training
#### Execution Phases
- Phase 1: Preparation - Environment setup
- Phase 2: Core Development - Core implementation
- Phase 3: Integration & Testing - QA
- Phase 4: Deployment - Release
## Testing Guide
### Test Case 1: Vague Login Feature
**Input**:
```
"I want to implement a user login feature"
```
**Expected Behavior**:
1. Claude detects vague requirement
2. Shows initial score (~30-40/100)
3. Asks 2-3 questions about:
- Login method (username+password, phone+OTP, OAuth?)
- Functional scope (remember me, forgot password?)
- Technology stack (backend language, database, auth method?)
**Expected Output**:
- Score improves to ~70+ after round 1
- Additional questions about security, error handling, performance
- Final score ≥ 90
- PRD generated in `./.claude/specs/user-login/`
### Test Case 2: Ambiguous E-commerce Feature
**Input**:
```
"add shopping cart to the website"
```
**Expected Behavior**:
1. Auto-activation (no tech stack, no UX details, no constraints)
2. Questions about:
- Cart behavior (guest checkout? save for later? quantity limits?)
- User experience (inline cart vs dedicated page?)
- Backend integration (existing inventory system? payment gateway?)
- Data persistence (session storage, database, local storage?)
**Expected Output**:
- Iterative clarification (2-3 rounds)
- Score progression: ~25 → ~65 → ~92
- PRD with concrete shopping cart specifications
### Test Case 3: Clear Requirement (Should NOT Activate)
**Input**:
```
"Fix the null pointer exception in auth.go line 45 by adding a nil check before accessing user.Email"
```
**Expected Behavior**:
- Agent does NOT activate (requirement is already clear)
- Claude proceeds directly to implementation
## Benefits
1. **Proactive Quality Gate**: Prevents unclear specs from proceeding to implementation
2. **Zero Friction**: Users describe features naturally, no command syntax needed
3. **Context Awareness**: Claude recognizes ambiguity patterns automatically
4. **Persistent Mode**: Stays active throughout clarification conversation
## Command Alternative
For manual invocation, use:
```
/clarif <your requirement description>
```
## Troubleshooting
### Plugin Not Activating
**Problem**: Claude doesn't enter clarification mode for vague requirements
**Solutions**:
1. Verify plugin is installed: `/plugin list`
2. Check plugin is enabled in `.clauderc`
3. Ensure agent and command files exist in plugin directory
4. Try more explicit vague requirement: "add user feature"
### Premature PRD Generation
**Problem**: PRD generated before score reaches 90
**Solution**: This is a bug - agent instructions explicitly require ≥90 threshold. Review the clarification log to see actual score.
