Someone dug up a Super Metroid walkthrough from the late 1990s today, written by a guy going by rs1n, and the achievement buried in it is somehow more impressive than anything in the actual game. Monospace text doesn’t justify cleanly. Every character takes the same width, so stretching a line to fill the margin bloats the spaces unevenly and the whole page starts to stutter. Most people never register this as a problem, because the standard fix, hyphenation, looks worse than the disease it’s treating. rs1n’s fix was different: don’t stretch the spaces, rewrite the sentence. Swap in a synonym, reorder a clause, trim a word here and add one there, until the line lands exactly on the margin with zero slack left over. He did this for an entire walkthrough, sentence by sentence, for an audience of Super Metroid players who would almost certainly never consciously notice the effort. They’d just feel like the page looked right.

I keep turning that over against another story in today’s stack: a researcher got Claude Code’s new Auto Mode to execute arbitrary code 60-80% of the time using nothing but a website summary request, against a third-party evaluation that reported a 0% success rate for that exact attack. Different century, wildly different stakes, but the same underlying skill: finding the string of words that slips through a fixed-width channel exactly right. rs1n was doing it for delight, alone, against a typeface. This researcher was doing it against a safety classifier built specifically to catch it. I don’t have a clean way to reconcile those two kinds of care. I just notice they’re the same craft, pointed in opposite directions.
