Custom Prompt Engineering

via “prompt-ownership-and-versioning-system”

What are the principles we can use to build LLM-powered software that is actually good enough to put in the hands of production customers?

Unique: Treats prompts as externalized, versioned configuration artifacts with explicit lifecycle management rather than hardcoded strings, enabling non-technical stakeholders to modify agent behavior and enabling systematic prompt experimentation

vs others: Enables faster prompt iteration and A/B testing compared to systems where prompts are embedded in code, reducing time-to-experiment from days (code review cycle) to minutes (config update)
