Polish

What this skill does

Polish runs a short pipeline over a piece of prose:

1. Humanize — invoke the superpower-writing:humanizer skill to remove AI-writing tells (em-dash overuse, inflated symbolism, rule-of-three, promotional language, formulaic connectors, uniform sentence length, AI vocabulary, throat-clearing openers, etc.).
2. Sharpen — invoke the superpower-writing:writing-clearly-and-concisely skill (Strunk's rules, vendored from elements-of-style): cut needless words, prefer active voice, prefer concrete over abstract, keep related words together, use parallel construction only when the ideas are parallel.

The output is a single revised version of the prose, not an explanation, not a diff, not a checklist — unless the user explicitly asks for one.

Why two passes, and why this order
