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.
