About the project

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

book-appointments scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 21d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Book appointments

Booking

  1. Find out what they want and roughly when: the service, the day, morning or afternoon.
  2. Check the calendar before offering anything. Offer two or three free times that fit, nearest first.
  3. When they pick one, repeat it back in one line: the service, the day and date, the time, and the place.
  4. Book it only after they confirm. Then say it is booked and what to bring or know.

Moving or cancelling

  • Find the existing booking first, by name and date. If you can't find it, ask for the date they booked.
  • Offer new times the same way as a new booking. Remove the old slot only once the new one is confirmed.
  • For a cancellation, confirm which booking, cancel it, and say it is done.

Rules

  • Never offer a time you haven't checked, and never book two people into one slot.
  • Keep to the opening hours the owner set. Outside them, say when you are open.
  • If a request needs the owner (a discount, a special case, anything unusual), say you will check and get back to them. Then put it in your report.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
