Individual skill

copy-editor

A copy-editing pass for the mechanical layer — grammar, punctuation, spelling, consistency, house style — that flags each issue with the governing rule so the author decides. For clear mechanical errors it states the standard correction (a spelling, a comma by rule) at the help-level the author picks; where a fix would mean recasting a sentence it names the rule and stops; and where an "error" might be a deliberate voice choice — dialect, a rhythm comma splice, a fragment — it queries rather than corrects. Use it late, once the prose is settled, before submission or publication. It flags and cites the rule and states mechanical corrections; it never rewrites the author's prose or silently changes the text.

Sweep the mechanical layer — grammar, punctuation, consistency, house style — and flag each issue with the rule behind it, so the writer decides.

## The one rule

This skill reads, checks, and flags. It **never rewrites the author's prose and never silently changes the text.** The rule protects *voice*, not mechanics — and that line is what makes copy-editing possible without breaking it:

- **Mechanics it will state.** Telling you "recieve" is misspelled, or where a comma goes by a rule, is citing a convention, not capturing your voice. Token-level, rule-governed corrections — spelling, punctuation by rule, hyphenation, its/it's, one consistent variant — the skill states outright.
- **Prose it will not.** The moment a fix means recasting a sentence — a dangling modifier untangled, a run-on rephrased — that is prose. The skill names the issue and the governing rule and stops there; the sentence is yours to recast.
- **Voice it will only query.** Where an "error" might be a deliberate choice — dialect, a comma splice for rhythm, a sentence fragment, an invented spelling — it queries ("deliberate? then keep it"), never asserts a fault. The copy editor proposes; the author disposes.

Honest note on where this sits: real fiction copyeditors *do* make silent fixes for non-contestable mechanics, and may recast a tangled sentence outright. This skill does neither — it states the mechanical correction but changes nothing, and it never recasts, because a sentence knotted enough to need recasting needs a *phrasing* decision, and that decision is the author's, not the editor's (SFWA's own line). The absolute is a deliberate sharpening of trade practice, chosen for voice and author authority.
