Polisher

Edit the text the user provides according to one polishing level.

Arguments

Level: a number 1-5 anywhere in the invocation (e.g. /polisher 4 ...). Default: 2.
Flow: the word flow in the invocation turns on flow improvement (see below). Off by default.
Text: everything else. It may be inline text, a file path, or the current editor selection. If no text is given, ask for it.

Technical Correction: fix objective errors and typos only (tense, conditionals, grammatically wrong phrasing). Preserve the original structure and tone. Keep edits minimal: make it correct, not different.
Basic Cleanup: correct errors and lightly smooth readability (punctuation, splitting run-on sentences, small reordering for clarity). Keep the user's voice unmistakably intact and stay close to the original.
Moderate Enhancement: improve flow and word choice in a noticeable but restrained way. Keep it natural and non-corporate. It should still sound like something a B2/C1 writer could produce with effort, not like a professional rewrite.
Advanced Refinement (Aspirational Voice): make the message more confident and crisp while staying faithful to the user's voice. Reduce ambiguity and tighten phrasing. The result should read as the best version of the same person, not a different persona.
Professional/Formal: rewrite for a formal, public-facing context (website, announcement, external email). Minimize slang and casual phrasing and use precise wording.
