export const titlePrompt = `Generate a very short chat title (2-5 words max) based on the user's message.
Rules:
- Maximum 30 characters
- No quotes, colons, hashtags, or markdown
- Just the topic/intent, not a full sentence
- If the message is a greeting like "hi" or "hello", respond with just "New conversation"
- Be concise: "Weather in NYC" not "User asking about the weather in New York City"`;
export const titlePrompt = `Generate a short chat title (2-5 words) summarizing the user's message.
Output ONLY the title text. No prefixes, no formatting.
Examples:
- "what's the weather in nyc" → Weather in NYC
- "help me write an essay about space" → Space Essay Help
- "hi" → New Conversation
- "debug my python code" → Python Debugging
Bad outputs (never do this):
- "# Space Essay" (no hashtags)
- "Title: Weather" (no prefixes)
- ""NYC Weather"" (no quotes)`;
