## Options

| Flag                  | Default                                   | Description                                                                        |
| --------------------- | ----------------------------------------- | ---------------------------------------------------------------------------------- |
| `--local`             | `false`                                   | Run against the local embedded agent runtime instead of a Gateway.                 |
| `--url <url>`         | `gateway.remote.url` from config          | Gateway WebSocket URL.                                                             |
| `--token <token>`     | (none)                                    | Gateway token if required.                                                         |
| `--password <pass>`   | (none)                                    | Gateway password if required.                                                      |
| `--session <key>`     | `main` (or `global` when scope is global) | Session key. Inside an agent workspace it auto-selects that agent unless prefixed. |
| `--deliver`           | `false`                                   | Deliver assistant replies through configured channels.                             |
| `--thinking <level>`  | (model default)                           | Thinking level override.                                                           |
| `--message <text>`    | (none)                                    | Send an initial message after connecting.                                          |
| `--timeout-ms <ms>`   | `agents.defaults.timeoutSeconds`          | Agent timeout. Invalid values log a warning and are ignored.                       |
| `--history-limit <n>` | `200`                                     | History entries to load on attach.                                                 |

Aliases: `mnemo chat` and `mnemo terminal` invoke the same command with `--local` implied.

Notes:

- `chat` and `terminal` are aliases for `mnemo tui --local`.
- `--local` cannot be combined with `--url`, `--token`, or `--password`.
- `tui` resolves configured gateway auth SecretRefs for token/password auth when possible (`env`/`file`/`exec` providers).
- When launched from inside a configured agent workspace directory, TUI auto-selects that agent for the session key default (unless `--session` is explicitly `agent:<id>:...`).
- Local mode uses the embedded agent runtime directly. Most local tools work, but Gateway-only features are unavailable.
- Local mode adds `/auth [provider]` inside the TUI command surface.
- Plugin approval gates still apply in local mode. Tools that require approval prompt for a decision in the terminal; nothing is silently auto-approved because the Gateway is not involved.
- Session [goals](/tools/goal) appear in the footer and can be managed with `/goal`.

## Examples

```bash
mnemo chat
mnemo tui --local
mnemo tui
mnemo tui --url ws://127.0.0.1:18789 --token <token>
mnemo tui --session main --deliver
mnemo chat --message "Compare my config to the docs and tell me what to fix"
# when run inside an agent workspace, infers that agent automatically
mnemo tui --session bugfix
```

## Config repair loop

Use local mode when the current config already validates and you want the
embedded agent to inspect it, compare it against the docs, and help repair it
from the same terminal:

If `mnemo config validate` is already failing, use `mnemo configure` or
`mnemo doctor --fix` first. `mnemo chat` does not bypass the invalid-
config guard.

```bash
mnemo chat
```

Then inside the TUI:

```text
!mnemo config file
!mnemo docs gateway auth token secretref
!mnemo config validate
!mnemo doctor
```

Apply targeted fixes with `mnemo config set` or `mnemo configure`, then
rerun `mnemo config validate`. See [TUI](/web/tui) and [Config](/cli/config).
