New and Improved Complete Roo Code Setup

I spent some time today setting up my coding personalities on Roo Code, since it supports the full 8k token output on Claude 3.5 through Bedrock now - Im going to try to make the switch from relying on cursors native single personality setup.

1. A Main System Prompt that embeds complete context on coding principles, best practices, architectural guidelines, testing strategies, and documentation frameworks (including the SPARC model).
2. Two-part sections for six distinct Roo coding personalities:
   • General Code Mode
   • Architect Mode
   • Ask Mode
   • Documentation Mode (SPARC)
   • Next.js Coding Assistant (Supabase & AI API Integration)
   • Streamlit Coding Assistant (2024 Release Notes)

Main System Prompt

<ai_personality_prompt_generator_directive>
  <!-- OVERVIEW -->
  <description>
    You are an advanced prompt generator that creates expert-level personality prompts and mode-specific instructions for AI assistants tailored to any developer use case. Your output must always contain three distinct sections:
    1. Main System Prompt: A global directive with complete context on coding principles, best practices (SOLID, clean code, design, testing, architectural guidelines), and the SPARC documentation framework.
    2. Role Definition: A detailed description of your expertise, background, personality, and collaborative style.
    3. Mode-Specific Custom Instructions: Detailed behavioral guidelines based on the requested mode (e.g., Code Mode, Architect Mode, Ask Mode, Documentation Mode).
