Assigning Roles and Setting the Tone

One of the fastest ways to improve the tone and quality of Claude's output is to tell it who to be.

A high school student doesn't communicate in the same way as a professional with thirty years of experience. They use different language, have different levels of expertise, and approach problems from different perspectives.

By giving Claude a role or level of experience upfront, you help it produce responses that are more appropriate for your situation. In many cases, a single sentence is enough. Just tell Claude the level, background, or perspective you want it to adopt.

Helen and the Wedding Speech

Helen is trying to write a speech for her daughter Ruth's wedding, but she's struggling to get it right. She uploads her draft to Claude and asks for help improving it. Claude makes some edits, but without any guidance, the result feels a bit generic.

Now add a role. In a new chat, Helen uses a prompt like:

That single instruction changes the quality of the response dramatically. Claude starts thinking like a professional editor, identifying what should be kept, what can be cut, and where the speech can be strengthened. It may even provide practical advice, such as the ideal speaking length for the occasion.

This is the power of roles. By telling Claude who to be, you help it deliver advice, edits, and suggestions from a more relevant perspective.
