VSCode–Finetune your AI instructions with /init

If you're using GitHub Copilot in Visual Studio Code, there's a powerful new feature that can save you time and make your AI-powered development workflow more efficient: the /init command. This slash command provides a quick way to set up custom instructions for your workspace or adapt your existing instructions to the specific project context, helping you establish consistent coding practices and AI responses across your projects.

What is the /init command?

The /init command is a chat slash command in VSCode that helps you quickly prime your workspace with custom instructions for GitHub Copilot. When you type /init in the chat input box, it automatically generates a .github/copilot-instructions.md file tailored to your workspace.

Think of it as a quick-start wizard for setting up AI guidelines that will influence how Copilot generates code and handles development tasks throughout your project.

How to use the /init command?

Using the /init command is straightforward:

  1. Open the Chat view in VSCode (you can use the GitHub Copilot icon in the Activity Bar)
  2. In the chat input box, type /init
  3. Press Enter

That's it! VSCode will start analyzing your workspace and automatically generate a .github/copilot-instructions.md file with custom instructions that match your coding practices and project structure.


After the file is generated, you should:

  1. Review the generated instructions carefully
  2. Make any necessary edits to align with your specific needs
  3. Commit the file to your version control system to share with your team

The generation is done using a init.prompt.md file that you can customize further if you want. No magic here!

As mentioned in the intro, this also works when you already have a .github/copilot-instructions.md file in place. In that case the /init command will review the existing settings and adapt them where necessary.

Nice!

    Podman– Command execution failed with exit code 125

    After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

    Cache stampede: when our cache turned against us

    While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...
