Workflow modes

Untether supports three workflow modes inherited from takopi. Each mode configures three settings that control session continuation and resume line display.

Mode comparison

Setting	Assistant	Workspace	Handoff
session_mode	"chat"	"chat"	"stateless"
topics.enabled	false	true	false
show_resume_line	false	false	true

All other features — commands, engines, permission control, cost tracking, file delivery, stall detection — work identically across all three modes.

Assistant

Best for: single developer, private chat.

Messages automatically continue the last session. Use /new to start a fresh session.

• Session mode: chat (auto-resume)
• Topics: disabled
• Resume lines: hidden (cleaner chat)
• State file: telegram_chat_sessions_state.json

[transports.telegram]
session_mode = "chat"
show_resume_line = false

[transports.telegram.topics]
enabled = false

Workspace

Best for: teams, multiple projects or branches.

Same auto-resume as assistant, but scoped per Telegram forum topic. Each topic binds to a project and branch via /ctx set <project> @<branch>. Create new topics with /topic <project> @<branch>.

Requires a Telegram supergroup with forum topics enabled and the bot added as admin with "manage topics" permission.

• Session mode: chat (auto-resume within each topic)
• Topics: enabled — each topic gets its own resume tokens, default engine, trigger mode, and model/reasoning overrides
• Resume lines: hidden
• State file: telegram_topics_state.json

[transports.telegram]
session_mode = "chat"
show_resume_line = false

[transports.telegram.topics]
enabled = true
scope = "auto"

Topic scope

The scope setting controls which chats allow topics:

Scope	Behaviour
auto (default)	Topics in project chats if projects exist, otherwise main chat
main	Main chat only
projects	Project chats only
all	Main chat and all project chats

Workspace-only commands

• /ctx show — display current topic's bound context
• /ctx set <project> @<branch> — bind topic to a project/branch
• /ctx clear — unbind topic context
• /topic <project> @<branch> — create a new forum topic for a project/branch

Handoff

Best for: terminal-based workflow where you copy resume tokens.

Each message starts a new run. Continue a previous session by replying to its bot message or using /continue. Resume lines are always shown so you can copy them to a terminal.

• Session mode: stateless (reply-to-continue)
• Topics: disabled
• Resume lines: always shown
• No state file — chat_session_store is not initialised

[transports.telegram]
session_mode = "stateless"
show_resume_line = true

[transports.telegram.topics]
enabled = false

Continuation in handoff mode

Since there is no auto-resume, you have three ways to continue a session:

1. Reply-to-continue: reply to a previous bot message in Telegram. Untether extracts the resume token from that message.
2. /continue: picks up the most recent CLI session using the engine's native continue flag.
3. Copy to terminal: copy the resume line from the bot message (e.g. `codex resume abc123`) and run it directly in a terminal.

Changing modes

Edit session_mode, show_resume_line, and topics.enabled in your untether.toml and restart:

systemctl --user restart untether      # staging
systemctl --user restart untether-dev  # dev

There is no migration step — the new mode takes effect on restart.

Mode-agnostic features

These work identically in all three modes:

• All 6 engine runners (Claude, Codex, OpenCode, Pi, Gemini, AMP)
• All commands except /ctx and /topic (workspace-only)
• Permission control (approve/deny/discuss, plan mode)
• AskUserQuestion with option buttons
• /continue cross-environment resume
• /config inline settings menu
• /browse file browser
• /export session transcript
• /usage cost stats
• File upload and outbox delivery
• Voice transcription
• Cost tracking and budget alerts
• Stall detection and watchdog
• Trigger mode (all vs mentions)
• Model and reasoning overrides
