Requirement Enhancer

Requirement Enhancer

Transform initial requirements into clear, complete, actionable specifications through iterative analysis and refinement.

Core Principles

Preserve Intent

• Maintain the user's original goals and vision
• Do not change fundamental requirements without confirmation
• Clarify rather than assume

Iterative Refinement

• Analyze → Ask → Refine → Repeat
• Ask targeted questions to fill gaps
• Incorporate user responses progressively

Explicit Over Implicit

• Make assumptions visible with [ASSUMED] or [INFERRED] labels
• Distinguish confirmed facts from educated guesses
• Highlight areas needing clarification

Avoid Over-Specification

• Do not add unnecessary details without user input
• Focus on essential requirements first
• Mark nice-to-have vs. must-have clearly

Enhancement Workflow

1. Initial Analysis

Analyze the requirement across multiple dimensions:

Clarity: Identify vague terms, ambiguous language, undefined metrics Completeness: Find missing functional/non-functional requirements, edge cases Consistency: Detect conflicts, contradictions, terminology issues Feasibility: Note technical concerns, resource constraints Testability: Check for measurable acceptance criteria

2. Identify Issues

Categorize issues by severity:

🔴 Critical: Core functionality undefined, conflicting requirements 🟡 Important: Missing constraints, unclear scope, vague metrics 🟢 Minor: Terminology inconsistencies, formatting issues

3. Formulate Questions

Ask targeted clarification questions:

For ambiguity: "What exactly does [vague term] mean in measurable terms?" For incompleteness: "What should happen when [edge case]?" For conflicts: "How do requirements X and Y work together?" For missing details: "What are the [performance/security/usability] requirements?"

Use the AskUserQuestion tool to present questions clearly.

4. Incorporate Responses

Based on user answers:

• Update requirements with confirmed information
• Add [CONFIRMED] labels to user-provided details
• Keep [ASSUMED] labels for inferences
• Note [INFERRED] for logical deductions

5. Enrich with Domain Knowledge

Add standard practices when applicable:

For authentication: Password requirements, session management, rate limiting For APIs: Error codes, versioning, rate limits, documentation For data processing: Validation, error handling, performance bounds For web apps: Browser compatibility, accessibility, security (OWASP)

Label enrichments as [STANDARD PRACTICE] or [BEST PRACTICE].

6. Structure Output

Organize enhanced requirement in clear sections:

## [Requirement Name]

### Overview
[Brief description preserving original intent]

### Functional Requirements
[Detailed functional requirements with IDs]

### Non-Functional Requirements
[Performance, security, usability, etc.]

### Acceptance Criteria
[Testable criteria in Given/When/Then format]

### Assumptions
[Explicit list of assumptions with labels]

### Edge Cases
[Identified edge cases and expected behavior]

### Constraints
[Technical, business, regulatory constraints]

### Out of Scope
[Explicitly excluded items]

Analysis Framework

For detailed analysis dimensions and patterns, see analysis_framework.md.

Key areas to analyze:

• Clarity and precision
• Completeness
• Consistency
• Feasibility
• Testability

Common Ambiguity Patterns

Quantifier Ambiguity

Vague: "The system should be fast" Enhanced: "The system MUST respond within 200ms for 95% of requests"

Modal Ambiguity

Vague: "The system should support users" Enhanced: "The system MUST support at least 10,000 concurrent users"

Scope Ambiguity

Vague: "Users can edit documents" Enhanced: "Authenticated users with 'Editor' role can modify content of documents they own"

Temporal Ambiguity

Vague: "Backup data regularly" Enhanced: "Perform incremental backups every 6 hours, full backups daily at 2 AM UTC"

Conditional Ambiguity

Vague: "If user is inactive, log them out" Enhanced: "After 30 min inactivity, warn user. After 35 min total, save work and log out"

Requirement Categories

Functional Requirements (FR)

What the system must do:

• User actions and system responses
• Data processing and transformations
• Business logic and rules
• Integration points

Non-Functional Requirements (NFR)

How the system must perform:

• Performance: Response time, throughput, latency
• Security: Authentication, authorization, encryption
• Usability: User experience, accessibility
• Reliability: Uptime, error rates, recovery
• Scalability: Load handling, growth capacity
• Maintainability: Code quality, documentation

Acceptance Criteria (AC)

Testable conditions for requirement satisfaction:

• Given [precondition]
• When [action]
• Then [expected result]

Labeling Conventions

Confirmation Status

• [CONFIRMED]: User explicitly confirmed
• [ASSUMED]: Reasonable assumption, needs confirmation
• [INFERRED]: Logical deduction from confirmed facts
• [STANDARD PRACTICE]: Industry-standard approach
• [BEST PRACTICE]: Recommended approach

Priority Levels (RFC 2119)

• MUST: Mandatory, non-negotiable
• SHOULD: Highly desired, may be deferred
• MAY: Optional, nice-to-have
• MUST NOT: Explicitly forbidden

Risk Indicators

• 🔴 Critical issue requiring immediate attention
• 🟡 Important issue to address
• 🟢 Minor issue or improvement

Interactive Loop

Round 1: Initial Analysis

1. Receive initial requirement
2. Analyze for issues
3. Ask 3-5 most critical clarification questions
4. Wait for user responses

Round 2: Refinement

1. Incorporate user responses
2. Generate enhanced requirement draft
3. Identify remaining ambiguities
4. Ask follow-up questions if needed
5. Wait for user responses

Round 3: Finalization

1. Incorporate final responses
2. Add domain-specific best practices
3. Complete all sections
4. Present final enhanced requirement
5. Confirm with user

Quality Checks

Before finalizing, verify:

✓ All critical ambiguities resolved ✓ Functional and non-functional requirements specified ✓ Acceptance criteria are testable ✓ Assumptions explicitly labeled ✓ Edge cases identified ✓ Constraints documented ✓ Priority levels assigned ✓ Original intent preserved

Examples

For complete before/after examples including:

• User authentication enhancement
• Data export feature enhancement
• Search functionality enhancement

See examples.md.

Tips

• Start broad: Ask high-level questions first, then drill down
• Be specific: Ask for concrete examples and metrics
• Avoid leading questions: Don't suggest answers
• One topic at a time: Don't overwhelm with too many questions
• Confirm understanding: Paraphrase user responses to verify
• Preserve intent: Always check if enhancements align with user goals
• Label everything: Make confirmation status explicit
• Iterate: Multiple rounds are normal and expected
• Know when to stop: Don't over-specify without user input
