How to escape json schema defaultSnippets snippet syntax

[RedCMD]

I've been making a schema for my extension and wanted to add some "defaultSnippets"
which worked fine until I tried to include the literal characters $1
it comes out as a tabstop as expected
but when I went to escape it, I got unexpected results and wasn't able to find an escaping solution

minimal schema:

{
	"$schema": "http://json-schema.org/draft-07/schema#",
	"title": "defaultSnippets",
	"type": "object",
	"properties": {
		"vscode bug": {
			"defaultSnippets": [
				{
					"label": "vscode bug",
					"body": [
						"$1",
						"\\$2",
						"\\\\$3",
						"$\\4",
						"$\\\\5",
						"\\$\\6"
					]
				}
			]
		}
	}
}

minimal json file with schema active:

trigger intellisense code completions with ctrl+space:

unexpected escaping:

userdefinedsnippets#_grammar states I can just escape the $ with a backslash, but it doesn't work

Maybe @aeschli can help here

The problem is that the item is stringified, so all \ become \\.

The solution is to use bodyText. There the string is taken as-is (not strigified)

{
	"$schema": "http://json-schema.org/draft-07/schema#",
	"title": "defaultSnippets",
	"type": "object",
	"properties": {
		"vscode bug": {
			"defaultSnippets": [
				{
					"label": "vscode bug",
					"bodyText": "[ \"\\$1\" ]"

				}
			]
		}
	}
}

the problem with bodyText is that it doesn't auto format the resulting snippet when inserted

however body correctly formats the snippet based on the user's indent settings etc

One more trick (my memory comes back):
In body, start your string literal with ^. Again, that string literal will not be stringified but inserted as is

{
	"$schema": "http://json-schema.org/draft-07/schema#",
	"title": "defaultSnippets",
	"type": "object",
	"properties": {
		"vscode bug": {
			"defaultSnippets": [
				{
					"label": "vscode bug",
					"body": [
						"^\"\\$1\""
					]
				}
			]
		}
	}
}

Thank you
that works well for json values
however it doesn't work for json keys

"body": {
	"^\\$1": "^\"\\$1\"",
	"$schema": "https://raw.githubusercontent.com/RedCMD/TmLanguage-Syntax-Highlighter/main/vscode.tmLanguage.schema.json",
	"^\\$schema": "https://raw.githubusercontent.com/RedCMD/TmLanguage-Syntax-Highlighter/main/vscode.tmLanguage.schema.json",
	"$${_///}schema": "https://raw.githubusercontent.com/RedCMD/TmLanguage-Syntax-Highlighter/main/vscode.tmLanguage.schema.json"
}
