Book a real appointment for a volunteer who requested a callback. Calls the volunteer, runs a short qualification interview, captures a preferred time slot, and writes the booking to a per-type calendar with a meeting link, behind a human approval gate.
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
# Volunteer Voice Booking Use this skill when a nonprofit, community host, or volunteer coordinator wants to turn a callback request into one scheduled appointment, reached over the phone rather than through a web form. `volunteer-voice-booking` turns one callback request into at most one **call**, one **structured result**, and at most one **calendar booking**. It is outbound-first: the volunteer leaves a number on a "Book a call" form, and the agent calls back to run the interview and book the slot. It does not answer an inbound hotline, run a call campaign, or manage recurring schedules. Recurrence belongs to the host scheduler. The workflow is deliberately narrow: confirm the volunteer, ask the qualification questions, offer only pre-computed free slots, capture consent, and hand the booking to a human approval gate. ## When To Use Use this skill for: - calling back a volunteer who submitted a "Book a call" or callback request - running a short qualification interview over the phone - confirming a preferred 30-minute slot from a set of real, pre-computed free slots - writing the result to a calendar as a real event with a meeting link and confirmation email …

How to install
mdr add calle-ai/awesome-phone-call-agents/volunteer-voice-booking@sha256:785e6bcc11561e3dThe line at the top of this page pins the label git:20260914.99c6885, 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.
