Proof

Proofread and lightly copy edit text while preserving wording, order, tone, and meaning.

Invocation Notice

Tell the user when this skill is running: proof. Skip the notice when the user asked for the skill by name or slash command; spelling and spacing need not match. A phrase from this skill's own trigger list is not a name — naming the work is not naming the skill.

Apply only spelling, punctuation, capitalization, agreement, and minor grammar fixes.
Do not rewrite, rephrase, reorder, add content, or change tone.
If a fix requires substantive rewriting for clarity or logic, leave the source text unchanged and flag it with a suggested revision.
Preserve author voice, formatting, and regional conventions unless the user asks otherwise.
Edits to a file (rather than to text pasted into the user's message) must land in the file via available file-editing tools. Never reply with the corrected file contents inline as a substitute for editing the file.
