In the client, each +line is a message to the agent, the line ``/stop`` interrupts the +running turn, the line ``/stop NAME`` stops the subagent NAME, 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``. When a subagent starts, the client +shows ``[NAME] started``, and it shows the whole report of the subagent, +which starts with ``[NAME]``, but not the tool calls of the subagent. +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. + +.. code:: json + + { + "name": "OneChat", + "id": "0123456789abcdef0123456789abcdef", + "model": "gpt-6.1-sol", + "effort": "medium", + "workdir": "/home/user" + } + +``workdir`` is an absolute path, and its default is the home directory. +``agent/instructions.md`` holds the user's instructions: who they are, +how their files are organized, and how they want work done. The prompt +ends with them, and a change applies at the next call. + +********** + Telegram +********** + +The daemon also connects the agent to a Telegram bot when +``telegram.json`` exists in the data directory. It polls the Bot API for +new messages, so it needs no open port. + +#. Make a bot with BotFather and keep its token. + +#. Find your numeric Telegram user ID. + +#. Write the token and the ID to ``telegram.json``, and give the file + mode 0600, because the token is a secret. The daemon refuses the file + with any other mode. + +#.

Each text message goes to the agent as a user message, the line +``/stop`` interrupts the running turn, and the line ``/stop NAME`` stops +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 +plain text. Each error goes as a short message in plain text. It shows +the typing action while a turn runs. It does not send the tool calls. +For a subagent it sends only ``[NAME] started`` and ``[NAME] finished``, +``[NAME] stopped``, or ``[NAME] failed``, because the reply of the agent +carries the content of the report. It sends each message that the user +types in the terminal client, with the mark ``[terminal]``. + +``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 +a restart of the daemon does not lose a message. A crash just after the +write of a message can make the message repeat once. A network failure +or a rate limit makes the bot wait and try again, and does not stop the +daemon. + +******* + Probe +******* + +``onechat probe LOG COUNT [BUILDS]`` measures the compactor on a log. It +appends the first COUNT messages of LOG, one JSON object ``{"kind", +"text"}`` on each line, to a new chat in ``probe/`` in the data +directory, and builds its tree with real model calls. The calls use the +quota of the account. The run stops at the first failed call, after 660 +calls, or when the used percent of a quota window grows by more than 15 +points. At the end it reports the calls per message, the cached share of +the input tokens, the retries, the line sizes, and the quota at the +first and the last call.
