copy-editing
An AI agent skill from coreyhaines31/marketingskills, scored 67 out of 100 by code.

What the author says it does
When the user wants to edit, tighten, proofread, or refresh existing copy, or asks whether to keep, cut, or change a line in it, without rewriting from scratch. Every edit removes AI tells: 'it's not X, it's Y' reveals, 'no X, no Y, no Z' lists, and sentences that trail into extra comma clauses. A request to fix one line gets a point edit to that line only. For new copy, see copywriting.
