+summary: "Terminal UI (TUI): connect to the Gateway from any machine"
+read_when:
+  - You want a beginner-friendly walkthrough of the TUI
+  - You need the complete list of TUI features, commands, and shortcuts
+---
+# TUI (Terminal UI)
+
+## Quick start
+1) Start the Gateway.
+```bash
+clawdbot gateway
+```
+2) Open the TUI.
+```bash
+clawdbot tui
+```
+3) Type a message and press Enter.
+
+Remote Gateway:
+```bash
+clawdbot tui --url ws://<host>:<port> --token <gateway-token>
+```
+Use `--password` if your Gateway uses password auth.
+
+## What you see
+- Header: connection URL, current agent, current session.
+- Chat log: user messages, assistant replies, system notices, tool cards.
+- Status line: connection/run state (connecting, running, streaming, idle, error).
+- Footer: connection state + agent + session + model + think/verbose/reasoning + token counts + deliver.
+- Input: text editor with autocomplete.
+
+## Mental model: agents + sessions
+- Agents are unique slugs (e.g. `main`, `research`). The Gateway exposes the list.
+- Sessions belong to the current agent.
+- Session keys are stored as `agent:<agentId>:<sessionKey>`.
+  - If you type `/session main`, the TUI expands it to `agent:<currentAgent>:main`.
+  - If you type `/session agent:other:main`, you switch to that agent session explicitly.
+- Session scope:
+  - `per-sender` (default): each agent has many sessions.
+  - `global`: the TUI always uses the `global` session (the picker may be empty).
+- The current agent + session are always visible in the footer.
+
+## Sending + delivery
+- Messages are sent to the Gateway; delivery to providers is off by default.
+- Turn delivery on:
+  - `/deliver on`
+  - or the Settings panel
+  - or start with `clawdbot tui --deliver`
+
+## Pickers + overlays
+- Model picker: list available models and set the session override.
+- Agent picker: choose a different agent.
+- Session picker: shows only sessions for the current agent.
+- Settings: toggle deliver, tool output expansion, and thinking visibility.
+
+## Keyboard shortcuts
+- Enter: send message
+- Esc: abort active run
+- Ctrl+C: clear input (press twice to exit)
+- Ctrl+D: exit
+- Ctrl+L: model picker
+- Ctrl+G: agent picker
+- Ctrl+P: session picker
+- Ctrl+O: toggle tool output expansion
+- Ctrl+T: toggle thinking visibility (reloads history)
+
+## Slash commands
+Core:
+- `/help`
+- `/status`
+- `/agent <id>` (or `/agents`)
+- `/session <key>` (or `/sessions`)
+- `/model <provider/model>` (or `/models`)
+
+Session controls:
+- `/think <off|minimal|low|medium|high>`
+- `/verbose <on|off>`
+- `/reasoning <on|off|stream>`
+- `/elevated <on|off>` (alias: `/elev`)
+- `/activation <mention|always>`
+- `/deliver <on|off>`
+
+Session lifecycle:
+- `/new` or `/reset` (reset the session)
+- `/abort` (abort the active run)
+- `/settings`
+- `/exit`
+
+## Tool output
+- Tool calls show as cards with args + results.
+- Ctrl+O toggles between collapsed/expanded views.
+- While tools run, partial updates stream into the same card.
+
+## History + streaming
+- On connect, the TUI loads the latest history (default 200 messages).
+- Streaming responses update in place until finalized.
+- The TUI also listens to agent tool events for richer tool cards.
+
+## Connection details
+- The TUI registers with the Gateway as `mode: "tui"`.
+- Reconnects show a system message; event gaps are surfaced in the log.
+
+## Options
+- `--url <url>`: Gateway WebSocket URL (defaults to config or `ws://127.0.0.1:<port>`)
+- `--token <token>`: Gateway token (if required)
+- `--password <password>`: Gateway password (if required)
+- `--session <key>`: Session key (default: `main`, or `global` when scope is global)
+- `--deliver`: Deliver assistant replies to the provider (default off)
+- `--thinking <level>`: Override thinking level for sends
+- `--timeout-ms <ms>`: Agent timeout (default 30000)
+- `--history-limit <n>`: History entries to load (default 200)
+
+## Troubleshooting
+- `disconnected`: ensure the Gateway is running and your `--url/--token/--password` are correct.
+- No agents in picker: check `clawdbot agents list` and your routing config.
+- Empty session picker: you might be in global scope or have no sessions yet.
