## Silent replies

The exact silent token `NO_REPLY` / `no_reply` means “do not deliver a user-visible reply”.

The exact silent token `NO_REPLY` / `no_reply` means "do not deliver a user-visible reply".

When a turn also has pending tool media, such as generated TTS audio, OpenClaw

strips the silent text but still delivers the media attachment.

OpenClaw resolves that behavior by conversation type:

If no explicit order is configured, OpenClaw uses a round‑robin order:

If no explicit order is configured, OpenClaw uses a round-robin order:

- **Primary key:** profile type (**OAuth before API keys**).

- **Secondary key:** `usageStats.lastUsed` (oldest first, within each type).

### Why OAuth can "look lost"

If you have both an OAuth profile and an API key profile for the same provider, round‑robin can switch between them across messages unless pinned. To force a single profile:

If you have both an OAuth profile and an API key profile for the same provider, round-robin can switch between them across messages unless pinned. To force a single profile:

- Pin with `auth.order[provider] = ["provider:profileId"]`, or

- Use a per-session override via `/model …` with a profile override (when supported by your UI/chat surface).

## Troubleshooting

- If commands seem stuck, enable verbose logs and look for “queued for …ms” lines to confirm the queue is draining.

- If commands seem stuck, enable verbose logs and look for "queued for ...ms" lines to confirm the queue is draining.

- If you need queue depth, enable verbose logs and watch for queue timing lines.

- Codex app-server runs that accept a turn and then stop emitting progress are interrupted by the Codex adapter so the active session lane can release instead of waiting for the outer run timeout.

- When diagnostics are enabled, sessions that remain in `processing` past `diagnostics.stuckSessionWarnMs` with no observed reply, tool, status, block, or ACP progress are classified by current activity. Active work logs as `session.long_running`; active work with no recent progress logs as `session.stalled`; `session.stuck` is reserved for stale session bookkeeping with no active work, and only that path can release the affected session lane so queued work drains. Repeated `session.stuck` diagnostics back off while the session remains unchanged.

## Recommended setup (API key, any provider)

If you’re running a long-lived gateway, start with an API key for your chosen

For Anthropic specifically, API key auth is still the most predictable server

setup, but OpenClaw also supports reusing a local Claude CLI login.

## OpenAI-compatible endpoints

OpenClaw’s highest-leverage compatibility surface is now:

OpenClaw's highest-leverage compatibility surface is now:

- `GET /v1/models`

- `GET /v1/models/{id}`

## Config

- `tools.exec.notifyOnExit` (default: true): when true, backgrounded exec sessions enqueue a system event and request a heartbeat on exit.

- `tools.exec.approvalRunningNoticeMs` (default: 10000): emit a single “running” notice when an approval-gated exec runs longer than this (0 disables).

- `tools.exec.approvalRunningNoticeMs` (default: 10000): emit a single "running" notice when an approval-gated exec runs longer than this (0 disables).

- `tools.exec.timeoutSec` (default: 1800): default per-command exec timeout in seconds. Per-call `timeout` overrides it; per-call `timeout: 0` disables the exec process timeout.

- `tools.exec.host` (default: `auto`; resolves to `sandbox` when sandbox runtime is active, `gateway` otherwise)

- `tools.exec.security` (default: `deny` for sandbox, `full` for gateway + node when unset)

openclaw config set agents.list[0].tools.exec.node "node-id-or-name"
