Ask HN: Metadata emotionally frames communication, but how do you convey it?

The "solution" that has begun to rain down is AI-assisted writing, but how else is this solved?

HN user @nybblesio began a comment with:

<sarcasm heavy="true" comedy-intended="true" do-not-hate-me="true" smiley="true">

...which is effective, efficient, and itself humorous.

► Does anyone know of a writer's resource guide as a way to avoid #feelsAngry problem of quickly written information coming across as terse or irritable?

I know the most popular solution to "socialize" writing tone is supposedly emoticon choice, but in practice emoticon volume has become overused to mean do-not-hate-me="true";smiley="true"; etc.

Hashtags are common as well #dontHateMeBro but can't writing convey metadata without requiring great writing skill?

It seems there should be more than simply the sandwich technique, starting and ending with "something nice" and conveying purely analytical or anything seeming difficult in the middle.

I've trained actors for decades, and more and more they are framing directions from the producer as something like "character tags". (After a detailed description from a director, an actor said recently "Got it. Hashtag selfInterested.")

What are effective ways to "tag" writing as intending kindness?
