What problem does it solve? Academic manuscripts accumulate awkward phrasing, inconsistent terminology, and over-budget sections, but careless copy editing risks silently altering numbers, citations, or technical meaning. This Skill performs a disciplined polish pass over LaTeX sections that improves clarity and flow while guaranteeing that no fact, figure, or reference key changes. ## Core Features & Use Cases - Meaning-preserving prose polish: Edits grammar, wordiness, tense, and flow in manus/secs/*.tex in place, enforcing the terminology canon in notes/notation.md and trimming toward per-section page budgets in notes/outline.md. - Protected-content conservation: Freezes all numbers, math, citation and label keys, % src: anchors, and \todo{} markers before editing, then verifies byte-level conservation and a successful build afterward. - Style profile authoring: A style run records the author's prose preferences as measurable dials in notes/style.md via interview, writing samples, or named presets, without touching any prose. - Use Case: After drafting a results section, run the polish pass to tighten it to its two-page budget, fix terminology drift against the notation canon, and receive a dated report plus follow-up tasks for any content-level cuts that require the drafting skill. ## Quick Start Ask the assistant to run stage-copy-editor on a specific section or the whole drafted manuscript to polish the prose without changing any numbers or citations.
