`openclaw agent` runs a single agent turn from the command line without an
inbound chat message. Use it for scripted workflows, testing, and
programmatic delivery. Full flag and behavior reference:
[Agent CLI reference](/cli/agent).

For strict, ephemeral CI or coding automation that should own setup, cleanup,
output projection, and process status, use [`openclaw agent exec`](/cli/agent#agent-exec).

## Quick start

<Steps>
  <Step title="Run a simple agent turn">
    ```bash
    openclaw agent --agent main --message "What is the weather today?"
    ```

    Sends the message through the Gateway and prints the reply.

  </Step>

  <Step title="Send a multiline prompt from a file">
    ```bash
    openclaw agent --agent ops --message-file ./task.md
    ```

    Reads a valid UTF-8 file as the agent message body.

  </Step>

  <Step title="Target a specific agent or session">
    ```bash
    # Target a specific agent
    openclaw agent --agent ops --message "Summarize logs"

    # Target a phone number (derives session key)
    openclaw agent --to +15555550123 --message "Status update"

    # Reuse an existing session
    openclaw agent --session-id abc123 --message "Continue the task"

    # Target an exact session key
    openclaw agent --session-key agent:ops:incident-42 --message "Summarize status"
    ```

  </Step>

  <Step title="Deliver the reply to a channel">
    ```bash
    # Deliver to WhatsApp (default channel)
    openclaw agent --to +15555550123 --message "Report ready" --deliver

    # Deliver to Slack
    openclaw agent --agent ops --message "Generate report" \
      --deliver --reply-channel slack --reply-to "#reports"
    ```

  </Step>
</Steps>

| `--verbose <on\|full\|off>` | Persist verbose level for the session (`full` also logs tool output) |
| `--timeout <seconds>`       | Override agent timeout (default 600, or config value)                |
| `--json`                    | Output structured JSON                                               |

## Behavior

- By default, the CLI goes **through the Gateway**. Add `--local` to force the
  embedded runtime on the current machine.
- Pass exactly one of `--message` or `--message-file`. File messages preserve
  multiline content after removing an optional UTF-8 BOM. Files larger than
  4 MiB are rejected before dispatch.
- After transient handshake retries, a Gateway timeout or closed connection
  fails the command with a stderr hint; the CLI never silently reruns the turn
  embedded. The Gateway may still finish an accepted turn, so verify Gateway
  and session state before retrying or rerunning with `--local`.
- Session selection: `--to` derives the session key (group/channel targets
  preserve isolation; direct chats collapse to `main`). With `--agent`,
  `--channel`, and `--to` together, routing follows the channel's canonical
  recipient and `session.dmScope`. Stable outbound-only identities use a
  provider-owned session isolated from the agent's main session.
- `--session-key` selects an explicit key. Agent-prefixed keys must use
  `agent:<agent-id>:<session-key>`, and `--agent` must match that agent id when
  both are supplied. Bare non-sentinel keys are scoped to `--agent` when
  supplied; for example, `--agent ops --session-key incident-42` routes to
  `agent:ops:incident-42`. Without `--agent`, bare non-sentinel keys are scoped
  to the configured default agent. Literal `global` and `unknown` remain
  unscoped only when no `--agent` is supplied.
- `--reply-channel` and `--reply-account` affect delivery only.
- Thinking and verbose flags persist into the session store.
- Output: plain text by default, or `--json` for structured payload + metadata.
- With `--json --deliver`, the JSON includes delivery status for sent,
  suppressed, partial, and failed sends. See
  [JSON delivery status](/cli/agent#json-delivery-status).

## Examples

```bash
# Simple turn with JSON output
openclaw agent --to +15555550123 --message "Trace logs" --verbose on --json

# Turn with a model override
openclaw agent --agent ops --model openai/gpt-5.4 --message "Summarize logs"

# Turn with thinking level
openclaw agent --session-id 1234 --message "Summarize inbox" --thinking medium

# Multiline prompt from a file
openclaw agent --agent ops --message-file ./task.md

# Exact session key
openclaw agent --session-key agent:ops:incident-42 --message "Summarize status"

# Legacy key scoped to an agent
openclaw agent --agent ops --session-key incident-42 --message "Summarize status"

# Deliver to a different channel than the session
openclaw agent --agent ops --message "Alert" --deliver --reply-channel telegram --reply-to "@admin"
```
