Module: Xeno::Channels

Defined in:
lib/xeno/channels.rb,
lib/xeno/channels/slack.rb

Overview

The channel registry. A channel (a) normalizes platform input into user messages, (b) owns the session's continuation token, and (c) decides delivery of agent output. HTTP is built in; agent/channels/*.rb declare the rest via the DSL:

Xeno.channel :slack do
signing_secret Rails.application.credentials.dig(:slack, :signing_secret)
bot_token     Rails.application.credentials.dig(:slack, :bot_token)
end

Delivery is a failable nicety: the durable truth lives in the transcript and event rows, so a failed post logs and moves on.

A per-reply delta sink (post-then-edit streaming) when the session's channel opts in; nil otherwise. Failable nicety like all delivery.
