Unable to format Agent, Skill, Prompt and Instruction files

[WoLfulus]

The Deno VSCode extension is unable to format AI related files, for example:

When trying to use Deno to auto format *.instructions.md, *.agent.md , SKILL.md files, VSCode won't allow it.

.vscode/settings.json

  // Good

  "[markdown]": { 
    "editor.defaultFormatter": "denoland.vscode-deno"
  },

  // VSCode complains

  "[skill]": {
    "editor.defaultFormatter": "denoland.vscode-deno"
  },
  "[prompt]": {
    "editor.defaultFormatter": "denoland.vscode-deno"
  },
  "[chatagent]": {
    "editor.defaultFormatter": "denoland.vscode-deno"
  },
  "[instructions]": {
    "editor.defaultFormatter": "denoland.vscode-deno"
  },
