Hey @devsargam, regarding issue: #176 about AI responses coming in long, unbroken paragraphs. I made a couple of changes:

1. Added a defaultSystemPrompt.ts file:

export const defaultSystemPrompt = `
Always respond in **markdown format** with:
- A clear title (## Heading)
- Subheadings (###) for logical sections
- Bullet points or numbered lists when appropriate
- Use code blocks (\`\`\`) for any code
- Keep content structured, readable, and well-formatted
`;

2. Updated ai.ts to pass this prompt to createCompletion:

await createCompletion(
  [...existingMessages, { role: Role.User, content: data.message }],
  data.model,
  (chunk: string) => {
    message += chunk;
    res.write(`data: ${JSON.stringify({ content: chunk })}\n\n`);
  },
  defaultSystemPrompt
);

This should make all responses more structured and easier to read.

Unfortunately, I haven’t tested this yet because it requires OpenRouter API keys. I can open a PR for these changes so they can be reviewed and tested when API access is available.

@adityapai05 you should not use system prompts usually in chat only use it for worst edge cases

[devsargam]

mainly becuase it gets added to the context window and tokens are consumed, which increases the cost
