Documentation Portfolio Skill

🔴 AI FIRST Quality Principle

Apply the AI FIRST principle: never accept first-pass quality. Minimum 2 iterations. Read all output, improve every section. No shortcuts.

Purpose

Defines the complete set of architecture documentation required for all Hack23 projects, ensuring comprehensive documentation supporting both current operations and future planning.

Required Documentation Files

Current State Documentation

• MINDMAP.md — System conceptual relationships
• SWOT.md — Strategic analysis and positioning

Future State Planning

• FUTURE_ARCHITECTURE.md — Architectural evolution roadmap
• FUTURE_DATA_MODEL.md — Enhanced data architecture plans
• FUTURE_FLOWCHART.md — Improved process workflows
• FUTURE_STATEDIAGRAM.md — Advanced state management

Documentation Standards

MUST

• Write in Markdown format
• Use Mermaid for all diagrams

MUST NOT

• Include sensitive information (secrets, credentials)
• Create stale documentation (update or delete)
• Duplicate information across documents (link instead)
• Use proprietary diagram formats (use Mermaid)
