call-synthetic-counterparty-detector SKILL.md skillA
call-synthetic-counterparty-detector from calle-ai/awesome-phone-call-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add calle-ai/awesome-phone-call-agents/call-synthetic-counterparty-detector@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Offline experimental pattern checks on supplied call metadata and text, returning advisory synthetic-voice hints without certifying identity or switching live protocols.
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
# Synthetic Counterparty Detector
The `call-synthetic-counterparty-detector` skill computes a heuristic score from supplied metadata and text. It does not extract audio features, implement PDSM, authenticate identity, or switch protocols. Its recommendation is an experimental hint for human review, not a calibrated probability or permission to bypass safeguards.
## Research Scope
The latency, duration and filler-word thresholds are demonstration choices, not a reproduced or validated deepfake model. See [research scope](references/research-papers.md).
## How it works
The detector ingests the call transcript and a metadata payload containing acoustic telemetry:
1. **Micro-latency variance**: Checks if the turn-taking latency is too consistent (variance < 500ms). Humans naturally vary their response times based on cognitive load.
2. **Zero-breath phrasing**: Checks if the caller spoke for an impossibly long duration (e.g. >15 seconds) without a biological pause (PDSM anomaly).
3. **Linguistic determinism**: Checks if the caller uses zero filler words ("um", "ah") over a long, complex sequence of speech.

How to install
mdr add calle-ai/awesome-phone-call-agents/call-synthetic-counterparty-detector@sha256:d4ad298074ccd87eThe line at the top of this page pins the label v1.0.0, 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.
