zeph-channels

Multi-channel I/O adapters (CLI, Telegram, Discord, Slack) for Zeph.

Overview

Implements I/O channel adapters that connect the agent to different frontends. Ships with a CLI channel, Telegram adapter with streaming support, and optional Discord and Slack adapters. The AnyChannel enum provides unified dispatch across all channel variants. All channels implement full feature parity for the Channel trait: streaming, attachments, and slash commands work identically regardless of the active frontend.

Key modules

Module	Description
`cli`	`CliChannel` — interactive terminal I/O with persistent input history (rustyline), prefix search, and `/image` command for vision input
`telegram`	Telegram adapter via teloxide with streaming; voice/audio message detection and file download; photo message support for vision input
`discord`	Discord adapter (optional feature)
`slack`	Slack adapter (optional feature); audio file detection and download with Bearer auth
`any`	`AnyChannel` — enum dispatch over all channels
`markdown`	Markdown rendering helpers

Re-exports: AnyChannel, CliChannel

[!NOTE] ChannelError is defined in zeph-core::channel and used directly by all channel adapters. zeph-channels does not re-export it.
