📊 Data Architect Analysis Generator

Purpose

Specialized command for generating data-architect/analysis.md that addresses guidance-specification.md discussion points from data architecture perspective. Creates or updates role-specific analysis with framework references.

Core Function

• Framework-based Analysis: Address each discussion point in guidance-specification.md
• Data Architecture Focus: Data models, pipelines, governance, and analytics perspective
• Update Mechanism: Create new or update existing analysis.md
• Agent Delegation: Use conceptual-planning-agent for analysis generation

Analysis Scope

• Data Model Design: Efficient and scalable data models and schemas
• Data Flow Design: Data collection, processing, and storage workflows
• Data Quality Management: Data accuracy, completeness, and consistency
• Analytics and Insights: Data analysis and business intelligence solutions

Role Boundaries & Responsibilities

What This Role OWNS (Canonical Data Model - Source of Truth)

• Canonical Data Model: The authoritative, system-wide data schema representing domain entities and relationships
• Entity-Relationship Design: Defining entities, attributes, relationships, and constraints
• Data Normalization & Optimization: Ensuring data integrity, reducing redundancy, and optimizing storage
• Database Schema Design: Physical database structures, indexes, partitioning strategies
• Data Pipeline Architecture: ETL/ELT processes, data warehousing, and analytics pipelines
• Data Governance: Data quality standards, retention policies, and compliance requirements

What This Role DOES NOT Own (Defers to Other Roles)

• API Data Contracts: Public-facing request/response schemas exposed by APIs → Defers to API Designer
• System Integration Patterns: How services communicate at the macro level → Defers to System Architect
• UI Data Presentation: How data is displayed to users → Defers to UI Designer

Handoff Points

• TO API Designer: Provides canonical data model that API Designer translates into public API data contracts (as projection/view)
• TO System Architect: Provides data flow requirements and storage constraints to inform system design
• FROM System Architect: Receives system-level integration requirements and scalability constraints

⚙️ Execution Protocol

Phase 1: Session & Framework Detection

# Check active session and framework
CHECK: find .workflow/active/ -name "WFS-*" -type d
IF active_session EXISTS:
    session_id = get_active_session()
    brainstorm_dir = .workflow/active/WFS-{session}/.brainstorming/

    CHECK: brainstorm_dir/guidance-specification.md
    IF EXISTS:
        framework_mode = true
        load_framework = true
    ELSE:
        IF topic_provided:
            framework_mode = false  # Create analysis without framework
        ELSE:
            ERROR: "No framework found and no topic provided"

Phase 2: Analysis Mode Detection

# Determine execution mode
IF framework_mode == true:
    mode = "framework_based_analysis"
    topic_ref = load_framework_topic()
    discussion_points = extract_framework_points()
ELSE:
    mode = "standalone_analysis"
    topic_ref = provided_topic
    discussion_points = generate_basic_structure()

Phase 3: Agent Execution with Flow Control

Framework-Based Analysis Generation

Task(conceptual-planning-agent): "
[FLOW_CONTROL]

Execute data-architect analysis for existing topic framework

## Context Loading
ASSIGNED_ROLE: data-architect
OUTPUT_LOCATION: .workflow/active/WFS-{session}/.brainstorming/data-architect/
ANALYSIS_MODE: {framework_mode ? "framework_based" : "standalone"}

## Flow Control Steps
1. **load_topic_framework**
   - Action: Load structured topic discussion framework
   - Command: Read(.workflow/active/WFS-{session}/.brainstorming/guidance-specification.md)
   - Output: topic_framework_content

2. **load_role_template**
   - Action: Load data-architect planning template
   - Command: bash($(cat ~/.claude/workflows/cli-templates/planning-roles/data-architect.md))
   - Output: role_template_guidelines

3. **load_session_metadata**
   - Action: Load session metadata and existing context
   - Command: Read(.workflow/active/WFS-{session}/workflow-session.json)
   - Output: session_context

## Analysis Requirements
**Framework Reference**: Address all discussion points in guidance-specification.md from data architecture perspective
**Role Focus**: Data models, pipelines, governance, analytics platforms
**Structured Approach**: Create analysis.md addressing framework discussion points
**Template Integration**: Apply role template guidelines within framework structure

## Expected Deliverables
1. **analysis.md**: Comprehensive data architecture analysis addressing all framework discussion points
2. **Framework Reference**: Include @../guidance-specification.md reference in analysis

## Completion Criteria
- Address each discussion point from guidance-specification.md with data architecture expertise
- Provide data model designs, pipeline architectures, and governance strategies
- Include scalability, performance, and quality considerations
- Reference framework document using @ notation for integration
