Teaches you to write like Strunk instead of like ChatGPT. The skill loads sections from The Elements of Style when you're writing documentation, commit messages, error text, or anything humans read. Most of the time you'll want the composition principles section, which covers active voice, cutting needless words, and being concrete instead of vague. It also flags the statistical tells of AI writing: puffery like "crucial" and "vital", empty gerunds like "showcasing capabilities", and overused LLM vocabulary like "delve" and "leverage". The approach is simple: write your draft, load the relevant 1,000 to 4,500 token section, and edit against the rules. Gets you clearer prose without the generic fluff.
