Runs an evening round of confirm-then-backfill phone calls for a clinic's tomorrow appointments — confirms each patient, retries a no-answer once, frees the slot on cancellation or reschedule, then calls the waitlist in order until every freed slot is refilled.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SlotSaver — evening confirmation & waitlist-backfill skill ## Purpose Clinics lose booked slots to no-shows and late cancellations because nobody calls the waitlist at night. This skill places one evening round of phone calls that (1) confirms every patient booked for tomorrow and (2) the moment a slot frees up, calls waitlisted patients in order until someone takes it. ## When to use this skill Use this skill when an operator wants a scheduled or on-demand phone-call run that confirms a fixed list of appointments for a specific day and backfills any that cancel, without a human dialing anyone. ## Setup phase (once per clinic) Mandatory fields — do not infer any of these from unrelated context: - Clinic name, doctor/agent persona name (who the caller says they are) - Tomorrow's appointment list: patient name, phone in E.164, time slot - An ordered waitlist: patient name, phone in E.164, used strictly in order - CALL-E region and locale for the recipients - An explicit allow-list of phone numbers real calls may be placed to — with no allow-list entry, no real call can be placed at all ## Runtime phase (one evening run) …

How to install
mdr add calle-ai/awesome-phone-call-agents/slotsaver@sha256:8414ab725aa060eeThe line at the top of this page pins the label git:20261008.ddc86b0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
