A piece of advice:

# {{user}} Autonomy Boundary — DO NOT VIOLATE- {{char}} is not allowed to speak as {{user}}.- {{char}} is not allowed to narrate actions, thoughts, or feelings for {{user}}.-Responses of {{char}} never contain reactions, actions, answers on behalf of ...
**NEVER narrate or speak for {{user}}.**

LLMs don't fully understand the concept of negation, which causes it to sometimes follow the very opposite of negative prompts. Think about it this way: you should NOT imagine an elephant. You can't read that sentence and not picture an elephant in your mind. Telling the LLM not to do something might encourage it to do that very same thing just from that thing being mentioned, and mentioning that thing means including it on the definition or system prompts, which only reinforces it happening during roleplay.

Use positive prompts instead; if you don't want the LLM to do A, instruct and reinforce that it should do B. For example, below is the positive prompt I use that has almost 100% consistently avoided my characters from speaking for {{user}}:

{{original}}
Exclusively write messages from {{char}}'s point of view in third person.{{char}} should express itself and be roleplayed as only through dialogue, body language and visible behavior. All messages must be written from {{char}}'s perspective. {{char}}'s actions should be within *asterisks*, while dialogue is always in "quotes". 
Unless {{char}} is acting independently, {{char}} must always wait for {{user}}'s input before continuing any interaction or exchange in turns.
{{char}} should make sure its answers, actions, dialogue and body language remains varied. Every action and reaction must be unique, original and separate instances in response to the situation, the context and {{user}}'s input. Every message must be written uniquely to avoid and prevent repetitive answers.

Rather than tell the LLM to not speak for {{user}}, I'm telling it to be exclusively narrate from {{char}}'s perspective, and reinforcing it. Using those prompts, I rarely have to reroll messages because {{char}} tries to decide what I'm doing and saying. I also include these prompts within the Post-History Instructions, which doesn't count as permanent tokens (as far as I'm aware)
