Hmm, I don't see fix.message being used anywhere. That's where the title of the fix is.

[fannheyward]

@lithammer yes, the fix.message didn't use

    "message": "`sys` imported but unused",
    "fix": {
      "message": "Remove unused import: `sys`",

The output.message is used.

VSCode + Ruff:

coc-pyright with ruff:

Will improve this.

There're two things:

1. diagnostic message, shows in floating/virtualText, warning the code error, this should use output.message
2. codeAction message, or codeAction title, this should use msg.message for better human reading

For the first one, if we use output.message:

This is not good for diagnostic reporting.
