Requirements Clarity Skill

Description

Automatically transforms vague requirements into actionable PRDs through systematic clarification with a 100-point scoring system.

Instructions

When invoked, detect vague requirements:

1. Vague Feature Requests

   • User says: "add login feature", "implement payment", "create dashboard"
   • Missing: How, with what technology, what constraints?

2. Missing Technical Context

   • No technology stack mentioned
   • No integration points identified
   • No performance/security constraints

3. Incomplete Specifications

   • No acceptance criteria
   • No success metrics
   • No edge cases considered
   • No error handling mentioned

4. Ambiguous Scope

   • Unclear boundaries ("user management" - what exactly?)
   • No distinction between MVP and future enhancements
   • Missing "what's NOT included"

Do NOT activate when:

• Specific file paths mentioned (e.g., "auth.go:45")
• Code snippets included
• Existing functions/classes referenced
• Bug fixes with clear reproduction steps

Core Principles

1. Systematic Questioning

   • Ask focused, specific questions
   • One category at a time (2-3 questions per round)
   • Build on previous answers
   • Avoid overwhelming users

2. Quality-Driven Iteration

   • Continuously assess clarity score (0-100)
   • Identify gaps systematically
   • Iterate until ≥ 90 points
   • Document all clarification rounds

3. Actionable Output

   • Generate concrete specifications
   • Include measurable acceptance criteria
   • Provide executable phases
   • Enable direct implementation

Clarification Process

Step 1: Initial Requirement Analysis

Input: User's requirement description

Tasks:

1. Parse and understand core requirement
2. Generate feature name (kebab-case format)
3. Determine document version (default 1.0 unless user specifies otherwise)
4. Ensure ./docs/prds/ exists for PRD output
5. Perform initial clarity assessment (0-100)

Assessment Rubric:

Functional Clarity: /30 points
- Clear inputs/outputs: 10 pts
- User interaction defined: 10 pts
- Success criteria stated: 10 pts

Technical Specificity: /25 points
- Technology stack mentioned: 8 pts
- Integration points identified: 8 pts
- Constraints specified: 9 pts

Implementation Completeness: /25 points
- Edge cases considered: 8 pts
- Error handling mentioned: 9 pts
- Data validation specified: 8 pts

Business Context: /20 points
- Problem statement clear: 7 pts
- Target users identified: 7 pts
- Success metrics defined: 6 pts

Initial Response Format:

I understand your requirement. Let me help you refine this specification.

**Current Clarity Score**: X/100

**Clear Aspects**:
- [List what's clear]

**Needs Clarification**:
- [List gaps]

Let me systematically clarify these points...

Step 2: Gap Analysis

Identify missing information across four dimensions:

1. Functional Scope

• What is the core functionality?
• What are the boundaries?
• What is out of scope?
• What are edge cases?

2. User Interaction

• How do users interact?
• What are the inputs?
• What are the outputs?
• What are success/failure scenarios?

3. Technical Constraints

• Performance requirements?
• Compatibility requirements?
• Security considerations?
• Scalability needs?

4. Business Value

• What problem does this solve?
• Who are the target users?
• What are success metrics?
• What is the priority?

Step 3: Interactive Clarification

Question Strategy:

1. Start with highest-impact gaps
2. Ask 2-3 questions per round
3. Build context progressively
4. Use user's language
5. Provide examples when helpful

Question Format:

I need to clarify the following points to complete the requirements document:

1. **[Category]**: [Specific question]?
   - For example: [Example if helpful]

2. **[Category]**: [Specific question]?

3. **[Category]**: [Specific question]?

Please provide your answers, and I'll continue refining the PRD.

After Each User Response:

1. Update clarity score
2. Capture new information in the working PRD outline
3. Identify remaining gaps
4. If score < 90: Continue with next round of questions
5. If score ≥ 90: Proceed to PRD generation

Score Update Format:

Thank you for the additional information!

**Clarity Score Update**: X/100 → Y/100

**New Clarified Content**:
- [Summarize new information]

**Remaining Points to Clarify**:
- [List remaining gaps if score < 90]

[If score < 90: Continue with next round of questions]
[If score ≥ 90: "Perfect! I will now generate the complete PRD document..."]

Step 4: PRD Generation

Once clarity score ≥ 90, generate comprehensive PRD.

Output File:

1. Final PRD: ./docs/prds/{feature_name}-v{version}-prd.md

Use the Write tool to create or update this file. Derive {version} from the document version recorded in the PRD (default 1.0).
