Customize GitHub Copilot CLI Status Line

Over the past few months, I have switched most of my development workflows to GitHub Copilot CLI. Whether I'm exploring a codebase, writing code, debugging, or even building a new application, I find myself in GitHub Copilot CLI most of the time. It's fast, it keeps me in the flow, and the agentic capabilities make it incredibly productive.

Many users have asked me how to track context usage in the CLI ?

First of all, you can always use the /context and /usage commands to get a snapshot of your current context window usage.

Nevertheless, you can also have a live status line that shows your token consumption and context usage percentage in real time, without needing to type any command, you just need to use the experimental statusLine.command feature to run a custom script to generate the status line content.

Experimental Feature

As of 1st of May 2026, statusLine.command is an experimental feature and is subject to change. The payload format, configuration keys, and behavior described here may evolve in future releases. I'll do my best to keep this post updated, but always check the official docs for the latest.

This post walks you through setting it up from scratch. I also document the full JSON payload that Copilot sends to your script — I captured it directly from a live session to build the reference table below.

I’ve also published two demonstrations on my YouTube channel:

I was at DevFest Nantes 2025, another great edition! Thank you to all the organizers, volunteers, sponsors, speakers and attendees for making it happen.

I had many great discussions about GitHub, DevSecOps, and especially GitHub Copilot and AI for developers in general.

AI for Developers Is Becoming Mainstream​

Many people are now using GitHub Copilot or its competitors. This is great to see — it means AI-assisted coding is now becoming mainstream.

If you are not using AI tools yet, I strongly encourage you to give them a try. They can really help you be more productive, write better code -yes!-, learn faster, and like for mebe happy to code more "stuff".

Nevertheless, I also noticed a lot of confusion and misconceptions about what AI can (and cannot) really do for developers.

Stop Using GenAI for Development Like It’s 2022!​

We’re in 2025, and Copilot is more than 4 years old now!
If you are still using it the same way you did 2 or 3 years ago, you’re missing out!

I often say:

“If you’re using Copilot the same way you were 3–4 months ago, you’re already behind.”

Too many developers still use Copilot only as:

  • a smart autocomplete, or
  • an embedded ChatGPT inside their IDE.

That’s fine for small tasks, but today, with context engineering & spec-driven development, you can do much more.

GitHub Copilot: How I use it, and Why I love it

Since its launch, GitHub Copilot has been a hot topic in the developer community. Some people love it, some people hate it, and some people are just curious about it. I am part of the first group, and I have been using it for more than a year now. I will not go into the details of how Copilot works, but I will share with you my experience with it, and how it has changed my life as a developer.

Copilot will help developers differently depending on the way they work and the phase of the project they are in. I will try to cover as many use cases as possible, but I will not be able to cover all of them. Here are the main uses cases I have for Copilot

  • Write code faster
  • Create new features much faster
  • Learn new things in context
