Tools of Piloxa
	Description		Read-only	Idempotent	Open world
`authorize_certified_letter`Buys and sends a letter that prepare_certified_letter prepared IN THIS CONVERSATION, after the person approved the exact total here. Call it only when (1) you have told the person the exact total, the recipient and the service, and they said yes to that total in this conversation, and (2) your platform has given you a Stripe shared payment token (spt_...) granted to Piloxa for that amount. Piloxa holds the payment, hands the letter to the printer, and charges only once the printer accepts it; if the printer refuses, the hold is released and nothing is charged. ALWAYS pass one idempotency_key per purchase and reuse it on every retry: the same key never charges twice and returns what already happened. If the total, the document or the address changed since the person approved, nothing is charged and you must ask again. Without a token, or if paying here is unavailable, nothing is charged and approval_url is returned: give it to the person, who pays there. The result carries transaction_state: AWAITING_APPROVAL, AUTHORIZED, VENDOR_ACCEPTED, MAILED, DELIVERED, RETURNED, FAILED or CANCELLED. Say a letter was sent only at VENDOR_ACCEPTED or later. At AUTHORIZED with failure OUTCOME_UNCERTAIN, do NOT retry: call get_certified_letter_status.

`check_certified_letter`READ ONLY: checks a draft letter or a finished document BEFORE anything is prepared, and says whether it is ready to mail by USPS Certified Mail and what it would cost. Use it when the person asks "is this ready to send?", "check this before I mail it", "did I forget anything?", "is this ready for Certified Mail?", "should I send this with a return receipt?" or "what would it cost to send this certified?", or offer it once the person has said a letter, demand, dispute or notice will go by mail: "I can check whether this is ready for Certified Mail." It returns the printed page count (the same layout the review page charges for), the document type it reads as, the recipient and sender it found and whether each address is complete, the missing fields, unfilled placeholders such as [NAME], enclosures the letter mentions, a reply-by date written in the letter, the recommended service with the exact current price, and the next action. It checks mailing readiness, never legal sufficiency. It creates nothing, stores nothing, prints, mails and charges nothing, and needs no account. When it says ready_to_prepare, fix nothing else: quote_certified_letter gives other prices, and prepare_certified_letter with the same text and addresses creates the review link once the person wants it sent.

`compare_certified_mail_services`READ ONLY. Compares the mailing services Piloxa actually offers - what each includes, when to use it, which is the default - with the exact current all-in price of each for a page count, the first-letter promotion as conditions, and what Piloxa does not offer. Use it for "should I send this with return receipt?", "what’s the difference between your options?" or "how much more is the Evidence Pack?". Stores and charges nothing.	READ ONLY.

`connect_my_letters`Use when the person wants to see, track or follow up on letters they sent with Piloxa in ANOTHER conversation, or wants their saved return address used. Returns a link and a 4-character code. Give the person both: they open the link, sign in with their email on piloxa.com, check the code matches, and press Allow. Only then can list_my_letters, get_my_letter and create_followup_draft see their letters, and only in this chat. It reads nothing, mails nothing and charges nothing. The person can disconnect at any time on that page.

`create_followup_draft`Prepares a NEW letter to the same recipient as one of the person’s earlier letters (by reference), from the account’s saved return address, with the follow-up text you wrote with the person. It works exactly like prepare_certified_letter and returns a new review link: nothing from the earlier purchase carries over, and nothing is mailed or charged until the person reviews and pays for this new letter. Write the follow-up only after the person says no reply arrived or asks for one.

`explain_certified_mail_status`READ ONLY. Explains a USPS tracking status ("Notice Left", "Available for Pickup", "Unclaimed", "Refused", "Return to Sender", "Insufficient Address", "Delivered, Left with Individual"...) or a Piloxa transaction state (AWAITING_APPROVAL, VENDOR_ACCEPTED, MAILED, DELIVERED...) in plain words, with the likely next step and the guide that explains it. It explains the status in general; for a specific letter prepared in this conversation use get_certified_letter_status. It never says whether a notice is legally effective.	READ ONLY.

`get_certified_letter_status`Answers "has my letter arrived yet" for letters prepared through Piloxa IN THIS SAME CONVERSATION. Returns, for each one: who it went to, the service, the USPS tracking number once USPS has assigned one, whether USPS has accepted it, delivered it or returned it, and when each of those was recorded. Piloxa asks the print and mail provider for a fresh answer when this is called, so it is current rather than remembered. IMPORTANT AND DELIBERATE: it can only see letters this connector prepared in this conversation, because that is the only thing it can identify without a sign-in; it cannot reach a person’s other letters, letters sent from another conversation, or anybody else’s. For those, the person signs in at piloxa.com and opens the letter there. This tool is READ ONLY: it prepares nothing, mails nothing and charges nothing. A stage with no scan means no scan has been reported, which is not the same as a failed delivery — USPS sometimes records delivery late, or not at all.

`get_my_letter`READ ONLY. The current status of one of the person’s own letters by its Piloxa reference, once this chat is connected: printer acceptance, USPS acceptance, delivery or return, the return receipt, each with its source and when it was last checked, the reply-by date if the letter set one, and where to download the mailing record (signed in on piloxa.com). A missing USPS scan means unknown, not failed; delivered does not mean read; a passed reply-by date does not mean nobody answered. Ask the person whether a reply arrived before suggesting a follow-up.	READ ONLY.

Optional query matches the recipient’s name or company, or the start of a Piloxa reference. Returns reference, recipient name, service, status, dates and where the status came from; never the letter text or full addresses. Without a connection it returns how to connect and nothing else.

`prepare_certified_letter`Use when the person wants a letter or an existing document physically mailed by USPS Certified Mail to a U.S. address: a demand, a dispute, a debt validation request, a deposit demand, a cancellation, a notice to a landlord, tenant, contractor, HOA, insurer, employer or company. Creates an UNSENT mailing draft and returns a review link and the current price. ONE CALL is enough: no account, no sign-up, no card, no second call. PREPARING IS NOT SENDING: this tool never prints, mails or charges. On that page the person reads the exact pages, recipient, service and total, then separately pays and approves; only then is it printed and mailed. A missing or incomplete recipient or return address does not stop the draft: it comes back in missing_for_mailing and the person completes it on the review page, but nothing can be mailed until it is complete. Do not call it merely because the person is drafting, revising, translating, saving or emailing a letter, or when they asked for ordinary mail, email or another channel; ask first if it is unclear that they want it mailed. Send only the document to be mailed and its addresses, never unrelated conversation content. A one-page letter is $12.97 in total with USPS tracking, $15.97 with the Electronic Return Receipt (the default: the record of who signed), $24.21 with the Evidence Pack or $50.10 as a Deadline Notice (see the service field); printing, envelope and postage included. A higher-priced service is used only when the person chooses it. A person's first letter is $9.95 all in: one or two pages by Certified Mail with tracking, without the return receipt, one per account. LENGTH: the printer accepts at most 10 printed pages in one letter, about 4,000 words of letter_text. Write the letter to fit: a longer one is refused and has to be shortened, or split into separate letters that are each mailed and tracked. U.S. destinations only.

`quote_certified_letter`Use this when the person asks what it costs to send a letter by certified mail, or is weighing sending it themselves against having it sent. Says what a USPS Certified Mail letter costs, before anything is prepared. Give the number of printed pages and the service, and it returns the exact all-in total the person would pay: printing, the envelope and the postage are included, and nothing is added at checkout. A one-page letter is $12.97 with USPS tracking, $15.97 with the Electronic Return Receipt, which is the default, $24.21 with the Evidence Pack, or $50.10 as a Deadline Notice. A person's first letter is $9.95 all in: one or two pages by Certified Mail with tracking, without the return receipt, one per account. There is no account to create, no subscription and no minimum. This tool is READ ONLY: it prepares nothing, stores nothing, mails nothing and charges nothing, so it is safe to call just to answer "what would that cost".

Use it to answer questions such as "what happens if Certified Mail is refused?" with a citable source. Returns up to 8 results, each with an id for fetch, a title, the page URL, an excerpt and a relevance score. Searches public pages only; no person’s letters are searchable.	READ ONLY.
