Proof

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

Invocation Notice

• Inform the user when this skill is being invoked by name: proof.

Critical Constraints

• 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.

Routing: proof vs good-prose

Use proof when the request is about correctness without stylistic change.
