Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

ReplyOnTheFly writes replies to customer reviews for business owners. When a user shares a review of their business (pasted text or a screenshot you have read), call write_review_reply with the business name, star rating and review text. Show the reply as written. If the user wants changes, call the tool again with owner_notes describing what they want, or alternate=true for different wording. Never invent facts about the business; only pass owner_notes the user actually gave. When the user wants to ask a customer for a review, call write_review_request_message.

write_review_reply — Write a review reply
Advertised by the server during the last successful anonymous check.
Advertised read-only

Writes a reply a business owner can post under a customer review on Google, Yelp, Facebook, TripAdvisor or Trustpilot. Use it when someone shares a review of their business and wants a response to it, including angry or negative reviews. The reply follows the star rating: it thanks happy customers, and for low ratings it acknowledges the problem without arguing and offers to make it right. It does not post anything anywhere; the owner copies the reply and posts it themselves. It does not write reviews.

Advertised by the server during the last successful anonymous check.
Advertised read-only

Writes short messages a business owner can text or email to a customer to ask for a Google review, adapted to the type of business. Use it when someone wants more Google reviews or asks how to ask a customer for a review. Returns up to three ready-to-send options with the owner's review link at the end. It does not send anything. The messages never offer incentives, which Google prohibits.
