Prompt Architecture & Roleplay Engineering FAQ

Why do standard AI companion prompts suffer from conversational collapse?

Most basic templates instruct the model to “love the user unconditionally and agree with everything.” This causes the LLM to skip natural emotional progression, leading to repetitive sycophantic praise and loss of user interest within 10 minutes. Persona Harbor architectures enforce reciprocal pacing, gentle resistance, and sensory anchoring.

How do I import these templates into SillyTavern or local backends?

You can copy the system prompt directly into your character card’s system prompt or description block. Alternatively, click “Customize in Builder” to export a complete, standardized Tavern V2 JSON file with all tags, tokens, and alternate greetings pre-bundled.

Are these prompt templates SFW or uncensored?

All prompt templates are authored with literary emotional intimacy suitable for SFW public testing. When deployed to uncensored engines (like OurDream, DarLink, or local Ollama / Aphrodite models), they naturally accommodate adult dynamics without artificial guardrail conflicts.
