The daemon owns the root agent in ``agent/`` in the data directory and
listens on the Unix socket ``onechat.sock`` there. In the client, each
line is a message to the agent, the line ``/stop`` interrupts the
-running turn, and Ctrl-D ends the client. The client shows the replies,
-the tool calls, and the first lines of each tool result as they happen.
-It also shows each message that the user sends from another client, with
-the client as a mark, such as ``[telegram] text``. The daemon is the
-only process that uses the token file while it runs, so ``onechat
-login`` and ``onechat probe`` refuse to start until it stops.

The agent runs commands with bash as the user in its working directory,
with no sandbox. It has the rights of the user, also on the token file.
+When the user asks for it, the agent starts subagents for long tasks.
+Each subagent has a name, such as ``GreenOtter``, and runs in the
+background while the agent answers other messages. It gets the view of
+the agent and its task, and it runs its tools as the agent does, in
+``agent/subagents/NAME/work``. A task in a repository gives the path of
+the repository. The steps of a subagent go to its own log in
+``agent/subagents/NAME``, not to the chat, and its final reply comes
+back to the agent as one message that starts with ``[NAME]``. The agent
+can send a subagent more messages: a running subagent reads them between
+its tool calls, and a finished one goes on from its log, and its reply
+comes back in the same way. When the user stops a subagent, the chat
+gets a note, and the report of the subagent is logged, but it starts no
+turn. Each model call of a subagent has the name in the ``agent`` field
+of ``agent/usage.jsonl``.
+
``agent/config.json`` holds the settings of the agent. The first start
writes it with the defaults and a random ID. Do not change the ID: the
prompt cache key comes from it.

The bot reads only the private chat of the owner and ignores all other
-updates. Each text message goes to the agent as a user message, and the
-line ``/stop`` interrupts the running turn. The bot sends the replies as
-plain text, in parts of at most 4096 characters, and each error as a
-short message. It shows the typing action while a turn runs. It does not
-send the tool calls. It sends each message that the user types in the
-terminal client, with the mark ``[terminal]``.

+the subagent NAME. The bot sends the replies in parts of at most 4096
+characters, with their Markdown as Telegram formats: bold, italic,
+strikethrough, code, code blocks, links, and headings as bold text. When
+Telegram refuses the formats of a part, the bot sends the part again as

``agent/telegram-offset.json`` holds the ID of the next update. The bot
moves it past an update only after the message is durable in the log, so
