A system prompt is an instruction placed at the very beginning of a conversation, usually invisible to the user, that defines the AI's identity, speaking style, behavioral rules, and boundaries. Unlike a regular prompt, it defines the character itself rather than any single question.
In Enclave, each character's persona, professional boundaries, daily rhythm, and speaking style are organized into the system prompt and structured memory — so characters stay consistent over a long relationship instead of starting from scratch every conversation.
