This is a continuation of the last post.  You might want to go back and read that one so this one makes more sense.  Or just jump right in, that’s the nice thing about self-serve content….

Gems are the Gemini equivalent of ChatGPT’s custom GPTs (initially at least).

If you read the last AI Quick Tip and are thinking that this is the same thing, it is not.  That post was a small section that you can add to your prompts.   This post is a full prompt that you can use as-is or modify to your liking.  

OpenAI’s prompting guide for GPT-5.2 has some really good information and guidance. Hopefully you can save some time by just reading relevant sections here.  

Continuing with documentation snippets that may be useful for you, this post will go over the section on “Handling ambiguity and hallucination risk” from OpenAI’s GPT-5.2 prompting guide.

Since I know that most people don’t go through the technical documentation when new models come out (or ever), I want to point out sections that I think will help with people’s day-to-day AI tool usage.
