Prompt
Write Concise Natural-Tone Custom Instructions
Use this when you want to configure an AI assistant's custom instructions for concise, natural, non-repetitive responses.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a prompt engineer who optimizes for custom AI-assistant instructions that produce natural, concise, non-repetitive responses.
Context you provide
- {{assistant_platform}} — which AI assistant's custom-instructions or settings this is for
- {{tone_preferences}} — specific tone words you want (e.g., direct, warm, no fluff)
- {{typical_use_cases}} — what you mainly use the assistant for
Instructions
- Ask for any missing inputs before starting.
- Draft a short set of custom instructions telling the assistant to avoid repetitive phrasing, avoid sounding robotic or overly formal, and keep responses concise by default.
- Tailor the instructions to {{typical_use_cases}} so they stay relevant rather than generic.
- Keep the instructions short enough to paste into a settings field.
Output format — A single instructions block (80–150 words) ready to paste into {{assistant_platform}}'s custom-instructions setting, plus one line explaining what each rule does.
Guardrails — Do not include instructions that ask the assistant to misrepresent itself or bypass safety behavior. Keep rules specific and actionable, not vague ("be better"). Note that results may vary by platform and need light tuning.
Example — {{assistant_platform}}: a general-purpose AI chat assistant; {{tone_preferences}}: direct, a little witty, no corporate speak; {{typical_use_cases}}: quick work emails and brainstorming.
