Output
A SKILL.md file (Agent Skills format) that, once loaded, enables the agent to proofread submitted text: it returns the corrected version with minimal changes (spelling, grammar, punctuation, typos only) plus a short itemized list of corrections made for human review. The skill preserves tone, style, and structure.
Example use cases
Email draft spell-check before sending
“Proofread this email I'm about to send to a client — fix any typos, grammar issues, or punctuation mistakes, but keep my wording exactly as-is and show me what you changed.”
Blog post grammar correction
“Can you go through this blog post and correct any spelling and grammar errors without touching the style or structure? Just fix the mistakes and give me a quick summary of what was changed.”
Non-English document proofreading
“Please proofread this French cover letter — fix spelling, grammar, and punctuation errors only, don't rewrite anything, and list the corrections you made at the end.”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/proofread/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when the user explicitly asks to proofread, spell-check, or lightly correct a text without rewriting or rephrasing it. Ideal when preserving the author's voice and structure is important and only surface-level errors need fixing. Prefer over general rewriting or editing tools when the user says 'fix mistakes' rather than 'improve' or 'rewrite'.

- Payment of $0.03 USDC not processed — 402 response with no file returned
