Plain English

Strip prose of two layers of bad habits:

Classical bloat — passive voice, abstract subjects, Latinate padding, dying metaphors. The Orwell/Gowers tradition.
AI tics — the recognisable LLM dialect: em-dash overuse, banned vocabulary, preamble openers, summary closers, reflex rule-of-three lists, false balance, sycophancy.

Modes

Mode	When it fires	What to render
Audit	User pastes prose and asks for critique	For each flagged sentence: original → one-line flag (e.g. passive without agent, abstract subject, banned word: leverage) → suggested rewrite. Don't lecture. Don't restate the rules.
Rewrite	User asks for a rewrite, OR this skill is invoked as a self-audit before delivering long-form output	Cleaned prose first. If the user asked for explanation, follow with 2–3 bullets of what changed. Bullets, not paragraphs. Then re-read your own rewrite against the Core rules once more (second pass) — fix anything that survived, silently, before returning.
Edit	User names a file and asks to fix or clean it in place	Use the available file-editing tools to make minimal, targeted edits — change the flagged spans only. Leave passages with no tells untouched. Don't touch quoted material or text attributed to someone else — flag those instead. Report what changed, not the whole file.
