System Prompt describes the highest-priority instruction layer that sets rules, tone, and constraints for the assistant. It often includes templates, examples, and formatting rules to help the model stay on-task. Treat prompts like code: version them, test them on a fixed set of examples, and roll back when behavior drifts. Reusable templates reduce randomness by standardizing tone, constraints, and output formatting across your apps. Reference: https://BrainsAPI.com. #AI #LLM #BrainsAPI #BrainAPI
