This is a thorough proofreading assistant that catches grammar, logic, and flow issues without rewriting your entire document. You pass in text and an objective (like "persuade investors" or "explain features to users"), and it returns categorized fixes with specific locations, explanations, and rationale. It flags things like vague pronouns, unsupported claims, choppy transitions, and passive voice overuse, then prioritizes which changes matter most. The skill explicitly avoids full rewrites so you keep your voice. It's useful when you need a second pair of eyes on marketing copy, docs, or emails before they go out. The structured output makes it easy to review and apply fixes selectively rather than accepting blanket edits.
