Applies Strunk and White's *Elements of Style* to any prose Claude writes for humans: docs, commit messages, error text, UI copy, reports. The full guide is about 12,000 tokens, so the skill recommends dispatching a subagent to copyedit when context is tight. Focuses on the classics like active voice, omitting needless words, and putting emphatic words at sentence ends. Honestly, these rules hold up a century later. If you're having Claude write anything beyond code comments, this will make the output tighter and more professional. The skill includes all 18 core rules plus a reference section on commonly misused words.
