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:

• 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.
