Requirements

Overview

Structured command to help create a requirements document by guiding through requirements discovery, practical scoping, and generating a single, consolidated requirements document with clear, practical language.

Create a requirements document following the established feature development process. First, read the feature development guide at @~/.local/share/dotfiles/ai/guides/feature-development-process.md and the vision document at @vision.md to understand the feature scope and documentation approach.

Note: If the project has a local copy of the guide at @project/guides/feature-development-process.md, you may reference that instead for project-specific modifications.

IMPORTANT: Start by creating a TODO list to track the 3 phases of requirements creation. Mark the first phase as "in_progress" and others as "pending".

Requirements Document Structure

Single Consolidated Document (requirements.md) includes:

User Stories & Business Needs:

• User stories structured by role
• Business capabilities and user workflows
• Core system capabilities the system must provide

Business Data & Rules:

• Business entities and data requirements (entities, relationships, business-level attributes and constraints)
• Business logic and rules that govern system behavior
• User experience requirements

Quality Attributes & Constraints:

• Performance, security, reliability, and scalability requirements
• Compliance and privacy controls
• Technical constraints and limitations

Integration & Success:

• Integration touchpoints with existing systems
• Development and testing approaches
• Success criteria and acceptance criteria
• Constraints and assumptions

Requirement Identification Format

All requirements must use systematic ID prefixes for easy cross-referencing in specs, plans, and discussions.

Format Examples:

**US-1.1.1**: As a staff member, I want to view custom field data...

**REQ-2.1.1**: The system must render form controls dynamically based on...

**SC-1**: Staff can view custom field values on detail pages.

Numbering Rules:

• Numbers follow document section hierarchy (section 2.1 → REQ-2.1.x)
• User stories in section 1.1 use US-1.1.1, US-1.1.2, etc.
• Requirements in section 3.2 use REQ-3.2.1, REQ-3.2.2, etc.
• Success criteria use simple sequential numbers (SC-1 through SC-N)

Existing System Patterns to Consider

When gathering requirements, check if existing system capabilities apply:

• Search: Full-text search capabilities
• File Attachments: Document/file upload and management
• Audit Trail: Change tracking and history
• Multi-tenancy: Data isolation per organization/tenant
• Permissions: Role-based access control
• Tagging: Classification and categorization systems
• Custom Fields: Extensible data fields

Ask early: "Which of these existing capabilities might apply to this feature?"

Process: Work Through These 3 Phases Sequentially

Phase 1: Requirements Discovery

Ask focused questions to gather ALL requirements (don't categorize yet):

• What specific capabilities does the system need to provide?
• What business entities does it need to manage (main concepts, relationships, business-level attributes)?
• What data does it need to store and what are the business constraints?
• What business rules need to be enforced?
• What are the different audiences (staff, members, public, admins)?
• How do requirements differ across these audiences?
• What should each audience be able to see and do?
• How do users interact with the system?
• What happens when there's no data? (Empty states for staff vs members)
• How is the data presented? (Feed-style, table, cards, etc.)
• What makes this feature usable for all technical skill levels?
• What are the security and permission requirements?
• What performance expectations exist?
• What integrations are needed with existing systems?
• What compliance or privacy requirements apply?

ONE QUESTION AT A TIME - Wait for answers before proceeding.

Phase 2: Practical Focus & Future Planning

For each discovered requirement, ask:

• Is this immediately practical for the current scope?
• Should this go in current requirements or future.md for later phases?
• Can we state this in clear, simple language?
• Is this appropriately scoped for the current phase?
• Is this testable and measurable?

Create future.md for requirements that are:

• Great ideas but beyond current scope
• Complex features requiring Phase 2/3 implementation
• Ideas worth preserving for future consideration
• Advanced features that build on the initial foundation

Keep in current requirements only what is:

• Immediately practical and achievable
• Essential for core functionality
• Written in clear, simple language

Phase 3: Document Generation

• Apply ID prefixes to all user stories (US-), requirements (REQ-), and success criteria (SC-) following the Requirement Identification Format above
• Create a single consolidated requirements.md document with the following structure:

1. User Stories & Business Needs - structured by role with clear business capabilities 2. Core System Capabilities - what the system must provide to users 3. Business Data Requirements - entities, relationships, business-level attributes 4. Business Rules & Logic - rules and constraints that govern behavior 5. User Experience Requirements - how the system should feel and behave 6. Quality Attributes & Constraints - performance, security, reliability, scalability 7. Integration Touchpoints - connections with existing systems 8. Development & Testing Approach - how the system will be built and validated 9. Success Criteria - clear acceptance criteria and definition of success 10. Constraints & Assumptions - scope boundaries and foundational assumptions

• Create future.md for deferred requirements (organized by user stories and technical phases)
• Update or create discussion-summary.md:

- Check if discussion-summary.md exists in the feature directory - If exists: Add a "Requirements Phase" section with: - Technical discussions and research from requirements phase - "Resolved Questions from Vision" subsection (table showing what was open and how resolved) - Update Key Decisions Log with new decisions (continuing numbering from vision) - Update Technical Context with newly referenced files - If not exists: Create it with full structure including Vision Phase placeholder

• Include table of contents with proper links in all documents
• Include systematic section numbering (1.1, 1.2, 2.1, 2.2, etc.) for precise cross-referencing
• Cross-reference the vision document for business context
• Use clear, practical language throughout
• Follow the exact structure from our feature development process
• When documenting key architectural decisions (separate page vs modal, feed vs table, etc.), capture the rationale (linkability, performance, UX, etc.)

Guidelines

• Ask ONE question at a time and wait for response
• Update your TODO list as you complete each phase
• Keep language clear and conversational, not corporate-speak
• Focus on immediately useful requirements, avoid over-engineering
• Organize requirements in logical, readable structure that serves the whole team
• Reference vision document and feature development process
• Stay practical and focus on readable, actionable documents
• Stay at Requirements Level: Focus on WHAT and WHY, not HOW

- Good: "System must track whether event is draft or published" - Avoid: "Use boolean flag for is_draft field" - Good: "Events belong to one organization" - Avoid: "Include organization_id foreign key" - Save technical implementation details (data types, table structures, field names) for the specification phase

• Expect Iteration: Requirements often get refined as users think through implications. This is normal and healthy. Be ready to update requirements based on new insights.
• When requirements change significantly (optional→required, add→remove features), update ALL related sections consistently

Getting Started Process

1. Create your 3-phase TODO list immediately
2. Ask user: "What feature directory are you working in? Please provide the full path (e.g., project/features/FT033-feature-name)"
3. Ask user: "Please tag your vision document with @vision.md so I can understand the feature scope"
4. Validate the directory exists and confirm where you'll create the requirements document
5. Review the vision document to understand feature context
6. Begin Phase 1 with the first requirements discovery question
7. Keep questions focused and wait for answers before proceeding to next questions
