AI Coding Assistant

Discover best prompts for AI coding assistant to automate tasks and improve coding efficiency

Struggling to Get Your AI Coding Assistant to Deliver

If you're searching for the best prompts for your AI coding assistant, chances are you're trying to automate some of your coding tasks, but your current approach isn't yielding the desired results. You might be spending too much time debugging, or the assistant's suggestions are not quite what you need. This is often because the prompts you're using are too vague or don't provide enough context for the AI to understand what you're trying to achieve.

Finding the Right Pattern

To get the most out of your AI coding assistant, you need to craft prompts that are specific, well-structured, and tailored to the task at hand. One pattern that works well is combining the /trim code, which helps to eliminate unnecessary information, with the SENTINEL code, which ensures the AI stays focused on the key aspects of the problem. By stacking these codes, you can create a prompt that is both concise and effective.

For example, let's say you're trying to get your AI assistant to generate a function that calculates the average of a list of numbers. A poorly crafted prompt might look like this:

Write a function to calculate the average of a list of numbers

Response:

def calculate_average(numbers):
    return sum(numbers) / len(numbers)

This response is not bad, but it's not quite what you were looking for. You wanted the function to handle edge cases, such as an empty list.

Using the /trim and SENTINEL codes, you can rephrase the prompt like this:

/trim Calculate the average of a list of numbers. Handle edge cases. SENTINEL: numbers, average, list

Response:

def calculate_average(numbers):
    if len(numbers) == 0:
        return None
    return sum(numbers) / len(numbers)

As you can see, the revised prompt yields a more comprehensive and robust response.

Common Pitfalls

Many people try using codes like /skeptic or /punch to get their AI assistant to provide more critical or creative responses. However, these codes are not always the best fit for coding tasks. /skeptic can lead to overly negative responses, while /punch can result in suggestions that are too radical or untested.

For instance, using the /skeptic code might look like this:

/skeptic Write a function to calculate the average of a list of numbers

Response:

I'm not sure this is the best approach. Have you considered using a library function instead?

While this response is not entirely unhelpful, it's not what you were looking for. Similarly, using the /punch code might yield a response that is too unconventional or untested:

/punch Write a function to calculate the average of a list of numbers

Response:

def calculate_average(numbers):
    return numbers.reduce(lambda x, y: x + y) / len(numbers)

This response uses an unusual approach that may not be compatible with all programming languages or environments.

Knowing When to Hold Back

It's essential to remember that AI coding assistants are not a replacement for human judgment and expertise. There are times when you should not rely solely on these tools, such as when working on critical or high-stakes projects. In these cases, it's crucial to review and test the code thoroughly, rather than relying on automated suggestions.

Additionally, AI coding assistants may not always be able to understand the nuances of human communication or the specific requirements of a project. In these situations, it's better to use the assistant as a starting point or for generating ideas, rather than relying on it to produce production-ready code.
