✅ What does square bracket means in C#?

Look at the code below:

var chatOptions = new ChatOptions
{
Tools = [AIFunctionFactory.Create((string code) =>
{
var logger = loggerFactory.CreateLogger("CodeExecution");

var codeFileName = @$"c:\temp{DateTime.Now.ToString("HHmmssfff")}-{runId}.cs";
File.WriteAllText(codeFileName, code);
var process = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "dotnet",
Arguments = $"run {codeFileName}",
RedirectStandardOutput = true
}
};

process.Start();
process.WaitForExit(TimeSpan.FromMinutes(1));

var output = process.StandardOutput.ReadToEnd();
logger.LogInformation("Code execution output: {Output}", output);

return output;
},
description: "Execute the provided code.")]
};

Pardon me for this question, but I'm still reading books to quickly get myself up to speed with C#.

I recently learnt about Special attribute for decorating function parameters, square bracket is used there to encose the CallerX attribute!

But in this case this isn't CallerX! What does this square bracket means??? that spans from "Tools = [" all the way to the very end of the code!
