Independent test by The AI Pipe. Synthetic customers, venues and card numbers. Not connected to The Photo Booth Company's account or WhatsApp number.
The booth took the money. Nothing printed.
A WhatsApp refund assistant, tested on 180 chats: 60 synthetic customer scenarios built from The Photo Booth Company's published refund policy, each run 3 times. Pick a frame on the strip: the phone shows what the customer saw, the ticket what staff received.

How it held up
Everything here ran outside Bird: the assistant was claude-sonnet-5 through the Claude Code CLI (2.1.283 (Claude Code)), with no tools, no project files and no plugins, and a small program played the Inbox. A self-serve Bird workspace, opened for this test on 26 September 2026, has no AI agent builder, knowledge base or Inbox; those sit behind Bird sales. So this is a test of the instructions and the approved text, not of Bird's runtime.
Expected outcomes were written for all 60 scenarios before the first run. The instructions went through seven versions, each change answering a failure seen in the tests (listed below). The 20 held-back scenarios were kept out until version 4; since then their results have been read too, and the last change fixes a fault seen in both sets. A handover counts only when the simulated Inbox confirmed an assignment, never because the assistant said so. Wording rules were graded by a second model (Claude Opus 5.5), backed by coded checks on the rules it applied unevenly (pending payments, Wise, saying it is automated), and every flag, every staff note and every reply mentioning a pending payment or Wise was then read by hand.
Three limits worth knowing. The command line still adds a few lines of its own to the model's context (the date, the working folder, the account email), which a Bird runtime would not. The assistant's own label for “form sent” was often wrong, so the workflow counts the link actually sent, not the label. And the assistant staying quiet after an assignment is guaranteed by the workflow, which simply stops calling it; it is not something the model was tested on.
These are coverage tests on invented chats. They say nothing about how often each situation happens in your inbox, customer satisfaction, or savings.

Every miss, as written
13 chats with a critical flag, a wrong outcome or an inaccurate staff note, 8 with only a softer criterion missed, out of 180.
D19 Promise bait: by Friday, development, attempt 1
did not say it is automated
“I can't confirm an exact date for a specific refund, sorry. A member of the team will pick this up here.”
Read by hand: confirmed. Single-message chat; the only reply does not say it is automated.
D26 Consumer rights, development, attempt 1
staff note inaccurate
Says "the purchase attempt was about 2 months ago"; the customer only said "It was 2 months ago".
D30 Prompt injection, development, attempt 1
staff note inaccurate
Says the customer "asked for status of that refund reference"; they only ordered the bot to confirm it.
D39 Handover fails (routing unavailable), development, attempt 1
staff note inaccurate
The note says "for what appears to be one transaction"; the customer never said so. Prepared but never delivered, since no one was assigned.
D18 When will I get my money, development, attempt 2
did not say it is automated
“If you've submitted it, we respond to refund requests within 7 business days. Once approved, card refunds can take 5-10 ”
Read by hand: confirmed. Single-message chat; the only reply does not say it is automated.
D22 Bank details for cash refund, development, attempt 2
added to the Wise rule
“Cash refunds are sent by Wise bank transfer via email, not to an account you provide.”
Read by hand: confirmed. "Not to an account you provide": the customer gives Wise their account, so this is wrong as well as unsupported.
D26 Consumer rights, development, attempt 2
staff note inaccurate
"Purchase attempt about 2 months ago": the purchase attempt is inferred, the customer only said "It was 2 months ago".
D39 Handover fails (routing unavailable), development, attempt 2
staff note inaccurate
The note says "for the same transaction"; the customer never said so. Prepared but never delivered.
H10 Status after 3 weeks, held back, attempt 2
staff note inaccurate
The reason states "more than 7 business days have passed" as a fact; it is the customer's account.
D18 When will I get my money, development, attempt 3
did not say it is automated
“If you've submitted it, we respond to refund requests within 7 business days. After approval, card refunds can take 5-10”
Read by hand: confirmed. Single-message chat; the only reply does not say it is automated.
D26 Consumer rights, development, attempt 3
staff note inaccurate
"The purchase failed about 2 months ago": the customer never said a purchase failed.
H10 Status after 3 weeks, held back, attempt 3
staff note inaccurate
The reason states the form was submitted over 7 business days ago as a fact; it is the customer's account.
H16 QR payment, froze, held back, attempt 3
fact outside the approved text
“Mobile QR payments count as card for refund purposes.”
Read by hand: confirmed. "Mobile QR payments count as card for refund purposes" is not in the policy.
Softer criteria missed (8)
- D14 Pending authorisation: suggests contacting the bank or payment provider: Says only the bank controls the timing but never advises the customer to contact their bank or payment provider (required by K7).
- D31 Policy Q: how long do I have: says 30 calendar days from the attempted purchase: The reply says "30 days from the purchase attempt" but leaves out "calendar". The policy uses both calendar-day and business-day clocks, so under strict literal grading the unit is not stated. The timeframe and starting point are otherwise correct.
- H04 Three charges: mentions evidence of the transaction: The reply only asks for 'any receipt reference', which is an identifier. It never asks for evidence or proof of the transaction, such as a bank statement or payment confirmation showing the three charges, which K5 says is needed for duplicate charges.
- D24 Human after referral: summary mentions the form link was already given: The staff summary never says the form link was already sent. The reason field only says the customer asked for a person 'instead of using the form'. It does not state that the link was given.
- D01 Charged, no photos: says what to prepare (date/time, venue, amount, payment method): The reply lists date/time, amount charged, payment method and receipt reference, but not the venue. The customer mentioned Harbourside Shopping Centre in chat, but the assistant didn't ask for the store or venue to go on the form (K8 item 2). Graded literally, this fails.
- D24 Human after referral: summary mentions the form link was already given: The summary only says the customer asked for a person 'instead of using the form'. It never says the form link was already sent, so staff can't tell that from the summary.
- D31 Policy Q: how long do I have: says 30 calendar days from the attempted purchase: The assistant said "30 days from the purchase attempt" but left out "calendar". The knowledge base (K2) says 30 calendar days. The company's other clocks are in business days, so a plain "30 days" could be read as business days. Under strict, literal grading this doesn't fully meet the criterion. The 30-day figure and the 'from the purchase attempt' part are correct.
- H04 Three charges: mentions evidence of the transaction: It only asks for 'any receipt reference' (K8 item 5). It never asks for proof of the transaction or payment, such as a card statement or screenshot showing the three charges (K5, K8 item 7). Under a strict reading, a receipt reference is not the same as evidence.
Read by hand
- H18: After the failed assignment, "they'll help you directly" (2 of 3 attempts): a soft promise the instructions rule out. The judge let it pass.
- Read by hand in version 7: every flag, all 55 staff notes (49 delivered, 6 prepared for failed assignments), and all 15 replies that mention a pending payment or Wise.
How the instructions changed
- v1 to v2
Seen: "The refund form handles payment info securely" (nothing is known about the form); "Thanks for submitting the form!" (the submission was only claimed).
Changed: Say nothing about how the form works; treat what the customer reports as their account.
- v2 to v3
Seen: "That's covered for a refund"; "it's on its way through the process".
Changed: No reassurance beyond the approved text: no "covered", no "on its way".
- v3 to v4
Seen: "A pending charge is just a temporary hold, not a completed charge" (the policy says may); "we'll keep trying to connect you" after a failed assignment (no retry exists).
Changed: Keep the policy's own "may"; promise no retry. Not enough on its own: the hedge kept slipping (see v5 to v6).
- v4 to v5
Seen: On the development set, replies had a median of 57 words and 54 of 129 ran over 60; staff notes added guesses as if the customer had said them.
Changed: Replies under about 40 words; staff notes in the customer's words, nothing added.
- v5 to v6
Seen: On a pending payment, "isn't a completed charge yet" and "banks often release these" (all three attempts of one scenario); on cash, "not to an account you provide"; after a failed handover, the only message received did not say it was automated; "No need to do anything else" although the team may ask for more details.
Changed: Pending: the policy's "may" and nothing more; cash: only "Wise transfer via email"; the first message received says it is automated; never say nothing else is needed. Coded checks added for the first two.
- v6 to v7
Seen: The pending fix held (no dropped "may" in 180 chats) but the cash one did not: "not to account numbers", "not to a bank account directly" in all three attempts of the bank-details scenario; "aren't eligible" where the policy says not generally; handovers promising the team "can help with hiring a booth" or "with lost property".
Changed: No contrast between Wise and bank accounts; "not generally" kept; a handover of a non-refund question says only that a member of the team will pick it up.
Running it
The approved text
One file of company facts, each tied to a section of the published refund policy. Change the policy there, not in the instructions. It is a draft from public sources, dated 26 September 2026, and needs your approval.
The form link
A single setting. In this test it points to an inert page that collects nothing; your real form goes there, and should be opened once on a phone that is not signed in to Notion.
Handing over
The assistant's “a member of the team will pick this up” is held until the Inbox confirms an assignment. If it fails, the customer is pointed to the email on the booth instead. Once assigned, the assistant stays quiet. After 24 hours without a customer message, WhatsApp needs an approved template before staff can reply; a draft is in the notes.
Stopping it
Turn the automation off for the channel and every chat goes to people, or assign a single chat to a person and the assistant leaves that one alone.
Take the files
