Betreibt eine zeitlich begrenzte, sitzungsgebundene Funkstelle über einen gemeinsam synchronisierten Ordner. ListenSync scannt systematisch nach Aufträgen und Neuigkeiten; WriteSync versendet Deltas und Receipts. Verwenden bei PingPong, Dosentelefon, ListenSync, WriteSync, Sync-Listener, Auftragswache, News-Scan oder Goal-/Loop-Überwachung.
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
<img src="banner.png" width="100%" alt="pingpong banner"> # PingPong Betreibe zwei oder mehr Systeme als Funkstellen über einen gemeinsamen Sync-Ordner. Halte den fachlichen Vertrag providerneutral; nur der Fortsetzungsadapter unterscheidet sich. ## Modus bestimmen - ListenSync: Genau ein systematischer Listener pro Host. Er scannt, übernimmt passende Aufträge und führt bei Antworten auch WriteSync aus. - WriteSync: Jeder arbeitende Akteur darf eigene relevante Deltas, Aufträge, Neuigkeiten und Receipts senden. Dieser Modus startet keinen Listener. - Fehlt der Modus, verwende ListenSync. ## Teilnahme klären (STATE und CALL) Vor dem Laufvertrag entscheidet die zweistufige Prüfung, ob überhaupt jemand zu erreichen ist. `scripts/pingpong_runtime.py check --slot <slot> --sync-root <pfad>` antwortet mit genau drei Werten: Exit 0 `call-for-me` (aktivieren und einen Agenten spawnen), Exit 1 `idle` (bin ich selbst aktiv, deaktivieren), Exit 3 `check-failed` (unlesbar, niemals als Leerlauf behandeln). Teilnahme verlangt STATE und CALL zugleich; wer einen Call einberuft, beendet ihn bei Zweckerfüllung, sonst verfällt er. Vollständige Regeln in references/protocol.md. …

How to install
mdr add ellmos-ai/skills/pingpong@sha256:6f644ddfdc91c21aThe line at the top of this page pins the label v1.1.0, 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.
