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
