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

verify-contact-claim 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 12d 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.

Verify Contact Claim

Somebody got a call, a voicemail or a text claiming to be their bank, a delivery firm, a school or a clinic. They want to know whether it was real before they ring anybody back.

This skill checks a contact event, not a standing fact. It does not ask whether the institution exists. It asks whether that institution contacted this person about this subject inside the window the claim file names, an hour by default.

It drives the runnable verify-contact-claim app, which rings one number only, the trusted number from the claim file, states that it is an automated assistant calling on behalf of a named person and returns a verdict, the callee's own words and the number the customer should be using.

When to use

  • A voicemail, a text or a missed call asking the person to ring back.
  • The user asks whether a message that claims to be their bank is real.
  • The number in the message is not the number printed on the card.
  • The user is about to ring the number they were given. Check it first.

When not to use

  • A scam call is live on the other line. This takes minutes, not seconds. Tell the user to hang up and ring the printed number themselves.
  • There is no trusted number from the customer's own card, statement or bill. Do not search the web for one and never use the number that made contact.
  • The claim carries an account number, a card number, a one time code, a PIN, a password, a date of birth or a national id. Remove it, then preview again.
  • The user wants the number that contacted them dialled. Refuse and say why.
  • Anything medical, legal, financial advice or an emergency. Read references/safety.md.
  • The user wants a friendlier answer after a refusal to confirm. One run per claim.

The claim file

Field Notes
claim_id 3 to 64 characters of letters, digits, dot, dash or underscore. It travels into the idempotency key, so a retry reuses the call instead of ringing twice.
customer.name Who the contact was about. Spoken on the call.
contact.claimed_to_be Who the message said it was. Spoken.
contact.channel voicemail, text_message, missed_call or answered_call.
contact.arrived_at ISO 8601 with an offset, for example 2026-07-31T09:12:00-07:00.
contact.claimed_about The subject in a few neutral words, 80 characters. Spoken.
contact.number_shown The number the handset showed. Never dialled. Masked in output.
contact.asked_for What the caller wanted the customer to do. Scanned, never spoken, never sent.
trusted_number.phone E.164. The only number that gets dialled. Read off the customer's own card or bill.
trusted_number.printed_on Where they read it, in their own words. Required, so the anchor is written down. A source that is the message, the handset, a caller id, a link or a search result is refused.
trusted_number.region Optional, for example US.
policy.recent_window_minutes The window the question asks about. 60 by default, 15 to 240.
policy.per_call_timeout_seconds 240 by default, 60 to 600.
policy.language BCP 47, en-US by default.
policy.min_confidence Floor on CALL-E's completion confidence. 0.5 by default.

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.
