 ## Constraints, Output format & Safety guards
 
 The cursor rules in this repository follow [The Three-Node Quality Framework for AI Prompts](./docs/articles/prompt-quality-framework.md), which ensures both comprehensive responses and safe execution. This framework consists of three distinct pillars: **constraints**, **output-format** and **safeguards**. Each node operates at different phases of the AI interaction timeline, creating a defense-in-depth strategy.
