Try it! ;) </p> <h2> Demo </h2> <p><a href="https://github.com/herol3oy/austen-cli/" rel="noopener noreferrer">https://github.com/herol3oy/austen-cli/</a></p> <p> <iframe src="https://www.youtube.com/embed/lUPhWGDNlTw"> </iframe> </p> <h2> My Experience with GitHub Copilot CLI </h2> <p>My experience with GitHub Copilot CLI was quite straightforward. As soon as I ran Copilot CLI, I jumped into <code>/plan</code> mode and started planning my CLI app. After a few iterations, I had a complete list of tasks and asked it to implement them. When the first version of the app was built, I was really surprised.</p> <p>It was impressive how Copilot reasoned through the problem, asked for my permission before running commands, and moved forward step by step. I learned a lot from debugging throughout the entire process.</p> <p>At some point, I wondered if there were best practices for using Copilot CLI, so I searched it and I was right:</p> <p><a href="https://docs.github.com/en/enterprise-cloud@latest/copilot/how-tos/copilot-cli/cli-best-practices" rel="noopener noreferrer">https://docs.github.com/en/enterprise-cloud@latest/copilot/how-tos/copilot-cli/cli-best-practices</a></p> <p>Thanks to the article, I found I can create a <code>.github/copilot-instructions.md</code>. So I did that with some simple but important instructions which I need the Copilot to always consider them.</p> <p>Anyway, I kept getting new ideas, and with just one or two prompts I was building new features. I eventually went a bit too far and added a killer feature to the app. To make sure it worked well, I planned it carefully and explained it clearly to Copilot. With a single prompt, we built it. I nailed it!</p> <p>Now the app generates a unique URL for each diagram and lets users share it with friends. That is just remarkable! </p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fw3oibn4ai0zew5wfuk1u.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fw3oibn4ai0zew5wfuk1u.png" alt="austen cli shareable link"></a></p> devchallenge githubchallenge cli githubcopilot
