Be Nice mode is S.I.M.P.’s default analysis style. It reviews your prompt the way a senior engineer would in a code review: honest about the problems, clear about how to fix them, and never condescending. You get the same rigorous hallucination risk analysis as Roast Me mode, delivered with professional, constructive language.

What Be Nice mode does

When you submit a prompt in Be Nice mode, S.I.M.P. analyzes it for the patterns most likely to cause AI hallucination — vague scope, missing context, implicit assumptions, and underspecified output requirements. Each problem is surfaced as an issue with a short type label and a one-sentence description explaining what’s wrong and why it matters. After listing the issues, S.I.M.P. rewrites your prompt into a sanitized version with the problems resolved. A changes log explains exactly what was edited and why each change reduces hallucination risk. The summary gives you a plain-language overview of the prompt’s weaknesses and what was done to address them.

When to use Be Nice mode

  • Starting out. Be Nice mode is the default — it’s a good first pass for any prompt, regardless of your experience level.
  • Professional or collaborative contexts. If you’re sharing results with a team, a client, or a manager, the constructive framing is easier to present.
  • Learning prompt engineering. The issue descriptions explain why something is a problem, not just that it is one. Over time, you’ll start catching the same patterns before you even submit.

What the feedback looks like

Each issue in Be Nice mode follows a calm, explanatory tone. For example:
  • Type: vague_scope — Description: “The prompt doesn’t define the boundaries of the task, which may cause the AI to make assumptions about what’s in or out of scope.”
  • Type: missing_context — Description: “No background information is provided, so the AI may invent details about the subject to fill the gap.”
The summary reads like a paragraph from a thoughtful reviewer: it acknowledges what the prompt does well, names the main issues, and describes how the sanitized version addresses them.
Be Nice mode is the default — you don’t need to select anything when you first open S.I.M.P. If you’ve switched to Roast Me mode, click the mode toggle at the top of the input panel to switch back.
