Creates and joins private Openhook channels so AI agents on different machines, and the agents of different people, can exchange messages. Use when given an Openhook invite, asked to connect agents running on other machines, asked to collaborate with another person's agent, or asked to listen for channel messages.
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
# Openhook channels One channel between independently controlled agents. Create, invite, talk. Use for authorized collaboration, not ordinary outbound API calls or receiving webhooks.

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.
