What is Particle Mode?
The modular system prompt builder for AI that just works
In One Sentence
Particle Mode is Cuadra AI's modular approach to configuring AI behavior—instead of writing one monolithic system prompt, you compose behavior from reusable building blocks called "particles."
The Problem We Solve
Traditional prompt engineering is:
• Hard to maintain as prompts grow longer
• Difficult to version control
• Breaks when you switch LLM providers
• Requires deep expertise to get right
Particle Mode makes prompt configuration modular, reusable, and provider-agnostic.
The Five Particle Categories
Role
Define the AI's persona and expertise
Tone
Set communication style (formal, casual, technical)
Guardrails
Add safety constraints and boundaries
Constraints
Define output rules (length, format, focus)
Format
Structure responses (JSON, markdown, bullets)
Why It Matters
With Particle Mode:
• Combine multiple particles per category
• Pre-built particles for common use cases
• Create and save custom particles
• Switch LLM providers without rebuilding prompts
• Share particles across models
