Sessions is the built-in admin messenger: the conversation list on the left,
the thread and composer on the right. Here you read conversations from every
channel, reply by hand, and unpack how an agent reached its answer — which tools
it called, how much it spent, and what subagents did. The screen refreshes about
every 5 seconds (paused mid-stream).
List and thread
On the left: search, a channel filter, rows with the last message and time,
active-row highlight and a ⋯ menu (Rename / Delete).
On the right: the message feed — user turns on the right, agent on the left,
system / tool / subagent rows muted.
Chat and attachments
The composer at the bottom: text, a paperclip for attachments (files are
staged as pending chips and sent with the message) and “Send”. Sending streams
over SSE, and the reply is typed out as it is generated.
View toggles
The bar above the thread has toggles (remembered per device, off by default):
**Sessions** is the built-in admin messenger: the conversation list on the left,
the thread and composer on the right. Here you read conversations from every
channel, reply by hand, and unpack how an agent reached its answer — which tools
it called, how much it spent, and what subagents did. The screen refreshes about
**every 5 seconds** (paused mid-stream).
## List and thread
- On the left: **search**, a channel filter, rows with the last message and time,
active-row highlight and a ⋯ menu (Rename / Delete).
- On the right: the message feed — user turns on the right, agent on the left,
system / tool / subagent rows muted.
## Chat and attachments
The composer at the bottom: text, a **paperclip** for attachments (files are
staged as pending chips and sent with the message) and "Send". Sending streams
over SSE, and the reply is typed out as it is generated.
## View toggles
The bar above the thread has toggles (remembered per device, off by default):
- **"turns & cost"** — appends a turns table: model, tokens, cost, status.
- **"tools"** — reveals tool-call and subagent rows plus live tool progress.
## Subagents
Subagent runs are shown **nested** under the parent turn with their own statuses —
you can see how the main agent delegated steps.
## How to use it
- **+ New session** — a modal: workspace, agent (or none), channel, title and the
first message.
- **Rename** and **delete** — from the row menu; delete is a hard cascade.
- Attach files in a new or an existing conversation.
