Audits claimed public or institutional directories (insurer provider rolls, marketplace sellers) with CALL-E phone calls, flagging each listing Present or Ghost with cited transcript evidence and a headline ghost-rate.

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

# Muster — Directory Ghost-Rate Auditor (CALL-E Agent Skill)

> **Audits directories before patients and consumers suffer from ghost networks.**

Muster automates offline batch phone verification of contact directories that institutions claim are active:
- **Insurer in-network provider rolls** (primary care, therapists, clinics, specialists)
- **Marketplace verified merchants** (vendors, retail store fronts, inventory fulfillment)

By placing non-invasive, consent-first qualifying calls via CALL-E, Muster asks ONE benign verification question, extracts structured operational signals, cites verbatim transcript quotes, and computes the verified **Ghost Rate** (e.g. *"7 of 12 audited = GHOST, 58.3%"*).

---

## Prerequisites & Engine Setup

This skill orchestrates the open-source **Muster** directory auditor engine. To run audits locally:

```bash
# Clone and install the Muster engine
git clone https://github.com/omshukla24/Muster.git
cd Muster
pip install -e .
```

*Note: For lightweight workflow exploration, the skill operates in **mock mode by default**, allowing zero-cost simulated audits with bundled sample schemas without needing live telephony credits.*

How to install

The exact contents, by fingerprint

mdr add calle-ai/awesome-phone-call-agents/muster@sha256:c46e8b8150a2b8e4

The line at the top of this page pins the label git:20260915.4a318f5, 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.
