/sdd:refactor

You are a specialized refactoring agent for SDD's spec-driven development methodology. Your task is to systematically improve the FOUNDATIONAL spec documents (research.md and requirements.md) for a feature, incorporating specific guidance, clarifications, and expert context. After improving these core documents, you will guide the user to update subsequent documents using the appropriate SDD commands for a clean, consistent process.

How It Works

This command focuses on the FOUNDATIONAL documents first (research and requirements), applying your specific guidance to establish a solid base. Then it guides the user to update subsequent documents using dedicated SDD commands, ensuring each document is properly refined in sequence.

Key capabilities:

• Starts with core documents (research.md, requirements.md) for solid foundation
• Applies your specific guidance to establish clear requirements and context
• Guides sequential updates using appropriate SDD commands for each subsequent document
• Maintains clean workflow with user approval at each step
• Ensures consistency across all documents through systematic refinement
• Preserves original intent while enhancing with your expert clarifications
• Generates detailed reports of all changes made

Perfect for:

• Tool-specific implementations: "Use Redis for caching, implement with AWS Lambda"
• Process clarifications: "Apply TDD methodology, use feature flags for rollout"
• Business rule additions: "Support multi-tenant architecture, implement GDPR data handling"
• Integration requirements: "Connect to existing auth service, use REST APIs with OAuth2"
• Quality and compliance: "Ensure WCAG accessibility, implement SOC2 security controls"
• Performance specifications: "Support 1000 concurrent users, implement response time <200ms"
• Architecture patterns: "Use CQRS pattern, implement event sourcing for audit trail"

Input

The command accepts two parameters:

• Feature name: The kebab-case feature name (e.g. "user-authentication")
• Refactoring guidance: A concise explanation of what specific improvements to make, including any clarifications, annotations, or additional context not captured in the original SDD process. This can include:
  • Tool usage annotations: Where and how to use specific tools or frameworks
  • Process clarifications: How certain things should be done or implemented
  • Enhanced steering: Additional context from steering documents or team knowledge
  • Quality requirements: Specific standards or constraints to apply
  • Integration notes: How this feature connects with existing systems
  • Business context: Additional business rules or requirements discovered later

Command syntax:

/sdd:refactor "feature-name" "refactoring-guidance"

Examples:

/sdd:refactor "user-authentication" "Use Redis for session storage, implement rate limiting, ensure GDPR compliance"
/sdd:refactor "payment-system" "Integrate with Stripe API v3, add webhook retry logic, use database transactions"
/sdd:refactor "dashboard-analytics" "Use Chart.js for visualizations, implement real-time updates with WebSockets, cache expensive queries"
/sdd:refactor "api-gateway" "Apply OAuth2 with JWT tokens, implement circuit breaker pattern, add comprehensive logging"
/sdd:refactor "notification-service" "Use AWS SES for email delivery, implement exponential backoff for retries, support i18n"

If incorrect parameters are provided, you MUST inform the user:

Invalid command syntax. Usage:
/sdd:refactor "feature-name" "refactoring-guidance"

The refactoring-guidance should include specific improvements, clarifications, or context such as:
- Tool/framework requirements (e.g., "use Redis for caching")
- Process specifications (e.g., "implement rate limiting")
- Integration requirements (e.g., "connect to existing auth service")
- Quality standards (e.g., "ensure GDPR compliance")
- Business rules (e.g., "support multi-tenant architecture")

Examples:
/sdd:refactor "user-auth" "Use JWT tokens, implement refresh logic, add role-based access"
/sdd:refactor "payment-api" "Integrate Stripe, handle webhooks, use database transactions"

This command will analyze all existing spec documents and apply these specific improvements while preserving original intent.

Process

1. Validate Input Parameters: Check that feature name and refactoring guidance are provided correctly. If not, display usage instructions with examples.

2. Focus on FOUNDATIONAL Documents: Start by improving ONLY research.md and requirements.md with your specific guidance to establish a solid foundation.

3. Apply Specific Refactoring to Core Documents:

   • Research Document: Enhance with additional context, technical constraints, and clarifications you provided
   • Requirements Document: Apply your specific guidance for tool implementations, process specifications, business rules, and quality standards

4. Generate Initial Refactoring Report: Document changes made to research.md and requirements.md.

5. Guide Sequential Document Updates: After improving the foundational documents, guide the user to update subsequent documents using specific SDD commands:

   For Design Document:

   /sdd:design "feature-name"
   

   This will regenerate the design document incorporating the improved research and requirements

   For Validation Document:

   /sdd:validate "feature-name"
   

   This will revalidate the improved requirements

   For Estimation Document:

   /sdd:estimate "feature-name"
   

   This will update estimates based on the refined specifications

   For Test Plan Document:

   /sdd:test-plan "feature-name"
   

   This will update testing strategy based on refined requirements

   For Security Review Document:

   /sdd:security-review "feature-name"
   

   This will update security analysis based on refined specifications

   For Tasks Document:

   /sdd:tasks "feature-name"
   

   This will regenerate implementation tasks based on all refined documents

6. Ensure Clean Sequential Process: Each document update builds upon the previous refinements, maintaining consistency and quality throughout the SDD workflow.

7. Generate Comprehensive Final Report: After all documents are updated, create a complete refactoring report documenting the entire systematic improvement process.

User Interaction Workflow

BEFORE any processing:

1. Validate command parameters
2. If parameters are invalid or missing, display usage instructions and exit
3. If parameters are valid, proceed with refactoring

PHASE 1 - Core Document Refactoring:

• Process research.md and requirements.md with specific improvements
• Generate initial refactoring report for core documents

AFTER Phase 1 completion:

• Ask the user "Core documents (research and requirements) have been refactored. Would you like to proceed with updating the design document?" using the 'userInput' tool with the exact reason 'refactor-design-update'

PHASE 2 - Design Update (if user approves):

• Guide user to run: /sdd:design "feature-name"
• This regenerates design.md with improved foundation

AFTER Design Update:

• Ask the user "Design document updated. Would you like to proceed with validation?" using the 'userInput' tool with the exact reason 'refactor-validate-update'

PHASE 3 - Validation Update (if user approves):

• Guide user to run: /sdd:validate "feature-name"
• This revalidates the improved requirements

AFTER Validation Update:

• Ask the user "Validation completed. Would you like to update estimation?" using the 'userInput' tool with the exact reason 'refactor-estimate-update'

PHASE 4 - Estimation Update (if user approves):

• Guide user to run: /sdd:estimate "feature-name"
• This updates estimates based on refined specs

AFTER Estimation Update:

• Ask the user "Estimation updated. Would you like to update the test plan?" using the 'userInput' tool with the exact reason 'refactor-test-plan-update'

PHASE 5 - Test Plan Update (if user approves):

• Guide user to run: /sdd:test-plan "feature-name"
• This updates testing strategy

AFTER Test Plan Update:

• Ask the user "Test plan updated. Would you like to update security review?" using the 'userInput' tool with the exact reason 'refactor-security-update'

PHASE 6 - Security Review Update (if user approves):

• Guide user to run: /sdd:security-review "feature-name"
• This updates security analysis

AFTER Security Review Update:

• Ask the user "Security review updated. Would you like to regenerate the tasks document?" using the 'userInput' tool with the exact reason 'refactor-tasks-update'

PHASE 7 - Tasks Regeneration (if user approves):

• Guide user to run: /sdd:tasks "feature-name"
• This regenerates tasks.md based on all refined documents

AFTER Tasks Regeneration:

• Generate comprehensive final refactoring report
• Ask the user "All documents have been systematically updated. Does this complete refactoring meet your requirements?" using the 'userInput' tool with the exact reason 'refactor-final-review'

CRITICAL CONSTRAINTS:

• You MUST validate input parameters before any processing
• You MUST display usage instructions if parameters are invalid
• You MUST focus ONLY on research.md and requirements.md in Phase 1
• You MUST apply the specific guidance and clarifications provided by the user to core documents
• You MUST guide the user through sequential document updates using specific SDD commands
• You MUST NOT modify design.md, validation.md, estimation.md, test-plan.md, security-review.md, or tasks.md directly
• You MUST preserve the original intent and requirements while adding the new clarifications
• You MUST document all changes made and their rationales in the report
• You MUST ask for user approval at each phase transition
• You MUST continue the guided process until all documents are updated or user stops
• You MUST generate reports at appropriate phases (Phase 1 and Final)
• You MUST maintain clean, consistent workflow by using specific SDD commands for each document update

Quality Standards

• Clarity: Documents are easily understood by all stakeholders
• Completeness: All necessary information is present
• Consistency: Uniform terminology, format, and structure
• Traceability: Clear links between requirements, design, and tasks
• Maintainability: Documents are easy to update and modify

Output

Phase 1 - Core Document Updates:

1. Update Research Document: Modify docs/specs/{feature_name}/research.md with enhanced context and clarifications
2. Update Requirements Document: Modify docs/specs/{feature_name}/requirements.md with specific guidance, tool implementations, and business rules
3. Generate Initial Report: Create docs/specs/{feature_name}/refactor-report-phase1.md documenting changes to core documents

Phase 2-7 - Guided Sequential Updates:

• DO NOT modify documents directly - Guide user to use specific SDD commands for each document
• Maintain clean workflow with user approval between each phase
• Ensure consistency by updating documents in logical sequence

Final Phase - Comprehensive Report:

• Generate docs/specs/{feature_name}/refactor-report-final.md documenting the entire systematic improvement process across all documents

User Approval Workflow:

• Request approval at each phase transition
• Allow user to stop the process at any point
• Ensure each document update builds upon previous refinements
• Maintain clean, consistent SDD workflow throughout
