no-show-shield

no-show-shield is a skill for Claude Code, Codex from CALLE-AI/awesome-phone-call-agents. It costs 67 tokens per session (693 once invoked), scanned A, original, MIT.

A batch appointment-confirmation workflow that calls every booking for a chosen day and records confirmed, reschedule-requested, or cancelled outcomes. It writes results to a calendar file and highlights cases that still need a person; preview and mock modes are available before real calls.

In plain words
What is it for?
Use it for a day's bookings at businesses such as trades services, mobile clinics, or salons when customers have authorised disclosed confirmation calls.
Why use it?
Operators otherwise have to make many confirmation calls and manually find the exceptions. Structured results make changes and unresolved bookings easier to review, while a call budget and preview help control live runs.

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

no-show-shield 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

No-Show Shield

Use this skill when a solo operator — a trades business, a mobile clinic, a single-chair salon — has explicit authority to place disclosed confirmation calls to the customers already booked into a given day, and wants the answers back as data rather than as voicemail they still have to action.

It differs from appointment-confirm in scope rather than intent: that skill confirms one appointment and deliberately leaves the diary alone. This one walks a whole day's book, applies each outcome to a calendar file, and reports only the exceptions. Use appointment-confirm when reviewing one result. This external implementation is an experimental batch reference: evaluate with mock/preview and fictional calendar data. Optional live evaluation is a supervised, operator-controlled handset demonstration, not an unattended customer campaign.

What it does

  1. Sync — loads a day's bookings from a JSON calendar file.
  2. Preview — prints who would be called, with no calls placed. Always available, and the default way to check a run before it happens.
  3. Run — places one CALL-E call per pending booking, with a result_schema of confirmed / reschedule_requested / cancelled / no_answer / unknown, plus a free-text reschedule preference.
  4. Write-back — applies each structured outcome to the calendar file, preserving the customer's stated preference verbatim.
  5. Summary — prints totals and a Needs you: line naming only the bookings a human must now handle.

When not to use it

  • Cold outreach, sales, or any call the recipient has not already transacted into. This skill confirms existing bookings only.
  • Medical, legal, or financial advice of any kind. The agent states the service name and time and nothing more; it does not discuss treatment, diagnosis, obligations, or money.
  • Emergencies or time-critical safety matters. It has no escalation path and must not be relied on where a missed call has consequences.
  • Debt collection, or any context where a recipient may feel pressured.

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.
