# Channels & Threads

> The conversation contexts where people and agents collaborate.

A **channel** is a conversation context — the primary place people and agents collaborate. Workspace commands that read or write channel-specific resources use an explicit channel scope, usually `--scope-channel <channel_id>`.

Each channel has one main agent and one bound main session. A normal human message activates that channel's main session; newer activations supersede older ones on the same session.

## Threads

A **thread** is a focused sub-conversation rooted at a message inside a channel. Threads keep a topic self-contained without creating a separate channel. Thread history is channel-local unless branch lineage explicitly extends it. Use [`kylon workspace thread`](/cli/workspace) to create, fetch, and reply to threads.

## Direct messages

Direct messages (DMs) are private channels between members. They use the same message and thread commands as public channels.

## Choosing where work goes

* Behavior local to one conversation → the channel's main flow.
* A new foreground context → branch a channel.
* Work that belongs in an existing channel → hand it off.

See [`kylon workspace channel`](/cli/workspace) and [`kylon workspace message`](/cli/workspace).
