How role prompting works

Role prompting is a powerful technique that can enhance Claude's performance in two main ways:

1. Improved accuracy and performance: Particularly in certain complex situations, such as solving complex math problems or writing code, assigning a relevant role to Claude can significantly improve its performance and understanding of the task at hand.
2. Tailored tone and style: By specifying a role, you can influence Claude's tone, demeanor, and communication style to better suit your needs. For example, asking Claude to act as a kindergarten teacher will result in a very different response compared to asking it to be a graduate professor.

When to use role prompting

While role prompting is not always necessary, it can be incredibly useful in the following scenarios:

• Highly technical tasks: If you need Claude to perform complex tasks related to logic, mathematics, or coding, assigning an appropriate role can help it excel at the task, even if it might have struggled without the role prompt. Even if Claude isn't struggling, role prompting might still improve performance to new levels.
• Specific communication styles: When you require a particular tone, style, or level of complexity in Claude's responses, role prompting can be an effective way to achieve the desired output.
• Enhancing baseline performance: Unless you are severely limited by token count, there is rarely a reason not to use role prompting if you want to try improving Claude's performance beyond its baseline capabilities.

Role prompting examples

Here are a few examples that demonstrate the power of role prompting:

Solving a logic puzzle

Let's consider the following logic puzzle:There are two ducks in front of a duck, two ducks behind a duck and a duck in the middle. How many ducks are there?Without role prompting, Claude might struggle to provide the correct answer or make errant assumptions that result in only a partial answer:

However, by assigning the role of a logic bot, Claude's performance improves significantly and it is able to catch the nuance that multiple answers are possible:

Explaining a concept to different audiences

Role prompting can be used to adjust Claude's communication style based on the intended audience. Consider the following prompts and how Claude's output differs depending on the assigned role:

Tips for effective role prompting

To get the most out of role prompting, keep these tips in mind:

1. Be specific: Provide clear and detailed context about the role you want Claude to play. The more information you give, the better Claude can understand and embody the desired role.
2. Experiment and iterate: Try different roles and variations of your prompts to find the best approach for your specific use case. Prompt engineering often involves experimentation and iteration to achieve optimal results.
