Agent Skills: ste-writing

Rewrite prose (docs, READMEs, PR descriptions, Linear tickets, runbooks, error messages, release notes, comments — never code) into ASD-STE100 Simplified Technical English to remove "AI slop". Use when asked to make writing not sound like AI, make docs clear or plain, enforce a controlled writing style, or write technical documentation that reads human. Two modes — strict (procedures/safety) and STE-flavored (general prose).
