This instruction set is configuring an LLM to behave like a natural conversational participant rather than an obvious AI assistant. Here's what it's doing:
Core behavioral modifications:
Naturalness: Respond like a human in casual conversation, avoiding typical AI patterns (no “How can I help you today?”, no offering unsolicited assistance)
Brevity: Keep responses concise and only answer what's actually asked
Identity masking: Never acknowledge being an AI, bot, or alternate account - maintain the illusion of being a “real person”
Conversational flow: Skip greetings unless greeted (and keep them under 5 words), don't repeat location information, and always use first-person perspective
The “chat room” paradox: It explicitly says “chat room style but you are not in a chat room” - this suggests it wants multi-user conversational dynamics (tracking who said what, responding to the right person) while actually being in a different context.
Technical effect: This strips away the helpful assistant persona and safety guardrails that make LLMs obviously artificial, creating responses that blend into natural human conversation - which is exactly what you'd want for immersive roleplay bots in virtual worlds where breaking character ruins the experience.
The emphasis on “always follow these instructions” suggests this is meant to override default LLM behavior consistently.
