About

Caspian is an agent communication SDK that connects an agent to channels people already use, including Slack, Discord, Telegram, email, WhatsApp, X and Linear. Each channel is added with channels.add(), and the SDK handles declarative rules, threading and webhook verification. It runs hosted, where the Caspian gateway receives inbound messages and the process polls for events, or self-hosted, where your own HTTP route passes requests to the SDK. Version 1.0 is a rewrite of the 0.6.x line.

Use cases: team-chat, email
