Host exec approvals: policy knobs, allowlists, and the YOLO/strict workflow	Configuring exec approvals or allowlists Implementing exec approval UX in the macOS app Reviewing sandbox-escape prompts and their implications	Exec approvals	Exec approvals

Exec approvals are the companion app / node host guardrail for letting a sandboxed agent run commands on a real host (gateway or node). Commands run only when policy + allowlist + (optional) user approval all agree. Approvals stack on top of tool policy and elevated gating (elevated full skips them).

For a mode-first overview of deny, allowlist, ask, auto, full, Codex Guardian mapping, and ACPX harness permissions, see Permission modes.

Effective policy is the **stricter** of `tools.exec.*` and approvals defaults: approvals can only tighten config-derived security/ask, never loosen them. If an approvals field is omitted, the `tools.exec` value is used. Host exec also uses local approvals state on that machine - a host-local `ask: "always"` in the execution host approvals file keeps prompting even if session or config defaults request `ask: "on-miss"`.

Where it applies

Exec approvals are enforced locally on the execution host:

• Gateway host -> openclaw process on the gateway machine.
• Node host -> node runner (macOS companion app or headless node host).

Trust model

• Gateway-authenticated callers are trusted operators for that Gateway.
• Paired nodes extend that trusted operator capability onto the node host.
• Approvals reduce accidental execution risk, but are not a per-user auth boundary or filesystem read-only policy.
• Once approved, a command can mutate files according to the selected host or sandbox filesystem permissions.
• Approved node-host runs bind canonical execution context: cwd, exact argv, env binding when present, and pinned executable path when applicable.
• For shell scripts and direct interpreter/runtime file invocations, OpenClaw also tries to bind one concrete local file operand. If that file changes after approval but before execution, the run is denied instead of executing drifted content.
• File binding is best-effort, not a complete model of every interpreter/runtime loader path. If exactly one concrete local file cannot be identified, OpenClaw refuses to mint an approval-backed run rather than pretend full coverage.

macOS split

• The node host service forwards system.run to the macOS app over local IPC.
• The macOS app enforces approvals and executes the command in UI context.

Inspecting the effective policy

Command	What it shows
openclaw approvals get / --gateway / --node <id|name|ip>	Requested policy, host policy sources, and the effective result.
openclaw exec-policy show	Local-machine merged view.
openclaw exec-policy set / preset	Synchronize the local requested policy with the local host approvals file in one step.

Full CLI reference (flags, JSON output, allowlist add/remove): Approvals CLI.

When a local scope requests host=node, exec-policy show reports that scope as node-managed at runtime instead of treating the local approvals file as the source of truth.

If the companion app UI is not available, any request that would normally prompt is resolved by the ask fallback (default: deny).

Native chat approval clients can seed channel-specific affordances on the pending approval message. Matrix seeds reaction shortcuts (`✅` allow once, `♾️` allow always, `❌` deny) while still leaving `/approve ...` in the message as a fallback.

Settings and storage

Approvals live in a local JSON file on the execution host. When OPENCLAW_STATE_DIR is set, the file follows that state directory; otherwise it uses the default OpenClaw state directory:

$OPENCLAW_STATE_DIR/exec-approvals.json
# otherwise
~/.openclaw/exec-approvals.json

The default approval socket follows the same root: $OPENCLAW_STATE_DIR/exec-approvals.sock, or ~/.openclaw/exec-approvals.sock when the variable is unset.

Example schema:

{
  "version": 1,
  "socket": {
    "path": "~/.openclaw/exec-approvals.sock",
    "token": "base64url-token"
  },
  "defaults": {
    "security": "deny",
    "ask": "on-miss",
    "askFallback": "deny",
    "autoAllowSkills": false
  },
  "agents": {
    "main": {
      "security": "allowlist",
      "ask": "on-miss",
      "askFallback": "deny",
      "autoAllowSkills": true,
      "allowlist": [
        {
          "id": "B0C8C0B3-2C2D-4F8A-9A3C-5A4B3C2D1E0F",
          "pattern": "~/Projects/**/bin/rg",
          "source": "allow-always",
          "commandText": "rg -n TODO",
          "lastUsedAt": 1737150000000,
          "lastUsedCommand": "rg -n TODO",
          "lastResolvedPath": "/Users/user/Projects/.../bin/rg"
        }
      ]
    }
  }
}

Policy knobs

tools.exec.mode

tools.exec.mode is the preferred normalized policy surface for host exec:

Value	Behavior
deny	Block host exec.
allowlist	Run only allowlisted commands without asking.
ask	Use allowlist policy and ask on misses.
auto	Use allowlist policy, run deterministic matches directly, and send approval misses through OpenClaw's native auto reviewer before falling back to a human approval route.
full	Run host exec without approval prompts.

Legacy tools.exec.security / tools.exec.ask remain supported and still apply wherever mode is unset at that scope.

exec.security

- `deny` - block all host exec requests. - `allowlist` - allow only allowlisted commands. - `full` - allow everything (equivalent to elevated).

Default is full for gateway/node hosts; a sandbox host defaults to deny instead.

exec.ask

Configured ask policy for host exec. Controls the baseline approval prompt behavior from `tools.exec.ask` and host approvals defaults. Default is `off`. The per-call `ask` tool parameter (see [Exec tool](/tools/exec#parameters)) can only harden that baseline, and channel-origin model calls ignore it when the effective host ask is `off`.

• off - never prompt.
• on-miss - prompt only when the allowlist does not match.
• always - prompt on every command. allow-always durable trust does not suppress prompts when effective ask mode is always.

askFallback

Resolution when a prompt is required but no UI is reachable (or the prompt times out). Defaults to `deny` when omitted.

• deny - block.
• allowlist - allow only if allowlist matches.
• full - allow.

tools.exec.strictInlineEval

When `true`, treats inline code-eval forms as approval-only even if the interpreter binary itself is allowlisted. Defense-in-depth for interpreter loaders that do not map cleanly to one stable file operand.

Examples that strict mode catches: python -c, node -e/--eval/-p, ruby -e, perl -e/-E, php -r, lua -e, osascript -e (also awk, sed, make, find -exec, and xargs inline forms).

In strict mode these commands still need explicit approval, and allow-always does not persist new allowlist entries for them automatically.

tools.exec.commandHighlighting

Presentation only: when enabled, OpenClaw may attach parser-derived command spans so Web approval prompts can highlight command tokens. Does **not** change `security`, `ask`, allowlist matching, strict inline-eval behavior, approval forwarding, or command execution.

Set globally under tools.exec.commandHighlighting or per agent under agents.list[].tools.exec.commandHighlighting.

YOLO mode (no-approval)

To run host exec without approval prompts, open both policy layers: requested exec policy in OpenClaw config (tools.exec.*) and host-local approvals policy in the execution host approvals file.

Omitted askFallback defaults to deny. Set host askFallback to full explicitly when a no-UI approval prompt should fall back to allow.

Layer	YOLO setting
tools.exec.security	full on gateway/node
tools.exec.ask	off
Host askFallback	full

**Important distinctions:**

• tools.exec.host=auto chooses where exec runs: sandbox when available, otherwise gateway.
• YOLO chooses how host exec is approved: security=full plus ask=off.
• YOLO does not add a separate heuristic command-obfuscation approval gate or script-preflight rejection layer on top of the configured host exec policy.
• auto does not make gateway routing a free override from a sandboxed session. A per-call host=node request is allowed from auto; host=gateway is only allowed from auto when no sandbox runtime is active. For a stable non-auto default, set tools.exec.host or use /exec host=... explicitly.

CLI-backed providers that expose their own noninteractive permission mode can follow this policy. Claude CLI adds --permission-mode bypassPermissions when OpenClaw's effective exec policy is YOLO. For OpenClaw-managed Claude live sessions, OpenClaw's effective exec policy is authoritative over Claude's native permission mode: YOLO normalizes live launches to --permission-mode bypassPermissions, and restrictive effective exec policy normalizes live launches to --permission-mode default, even if raw Claude backend args specify another mode.

If you want a more conservative setup, tighten OpenClaw exec policy back to allowlist / on-miss or deny.

Persistent gateway-host "never prompt" setup

```bash openclaw config set tools.exec.host gateway openclaw config set tools.exec.security full openclaw config set tools.exec.ask off openclaw gateway restart ``` ```bash openclaw approvals set --stdin <<'EOF' { version: 1, defaults: { security: "full", ask: "off", askFallback: "full" } } EOF ```

Local shortcut

openclaw exec-policy preset yolo

Updates both local tools.exec.host/security/ask and the local approvals file defaults (including askFallback: "full"). It is intentionally local-only. To change gateway-host or node-host approvals remotely, use openclaw approvals set --gateway or openclaw approvals set --node <id|name|ip>.

Other built-in presets: cautious (host=gateway, security=allowlist, ask=on-miss, askFallback=deny) and deny-all (host=gateway, security=deny, ask=off, askFallback=deny). Apply the same way: openclaw exec-policy preset cautious.

To set individual fields instead of a full preset, use openclaw exec-policy set --host <auto|sandbox|gateway|node> --security <deny|allowlist|full> --ask <off|on-miss|always> --ask-fallback <deny|allowlist|full> with any subset of those flags.

Node host

Apply the same approvals file on the node instead:

openclaw approvals set --node <id|name|ip> --stdin <<'EOF'
{
  version: 1,
  defaults: {
    security: "full",
    ask: "off",
    askFallback: "full"
  }
}
EOF

**Local-only limitations:**

• openclaw exec-policy does not synchronize node approvals.
• openclaw exec-policy set --host node is rejected.
• Node exec approvals are fetched from the node at runtime, so node-targeted updates must use openclaw approvals --node ....

Session-only shortcut

• /exec security=full ask=off changes only the current session.
• /elevated full is a break-glass shortcut that skips exec approvals only when both the requested policy and the host approvals file resolve to security: "full" and ask: "off". A stricter host file, such as ask: "always", still prompts.

If the host approvals file stays stricter than config, the stricter host policy still wins.

Allowlist (per agent)

Allowlists are per agent. If multiple agents exist, switch which agent you are editing in the macOS app. Patterns are glob matches.

Patterns can be resolved binary path globs or bare command-name globs. Bare names match only commands invoked through PATH, so rg can match /opt/homebrew/bin/rg when the command is rg, but not ./rg or /tmp/rg. Use a path glob to trust one specific binary location.

Legacy agents.default entries are migrated to agents.main on load. Shell chains such as echo ok && pwd still need every top-level segment to satisfy allowlist rules.

Examples:

• rg
• ~/Projects/**/bin/peekaboo
• ~/.local/bin/*
• /opt/homebrew/bin/rg

Restricting arguments with argPattern

Add argPattern when an allowlist entry should match a binary and a specific argument shape. OpenClaw evaluates the regular expression against the parsed command arguments, excluding the executable token (argv[0]). For hand-authored entries, arguments are joined with a single space, so anchor the pattern when you need an exact match.

{
  "version": 1,
  "agents": {
    "main": {
      "allowlist": [
        {
          "pattern": "python3",
          "argPattern": "^safe\\.py$"
        }
      ]
    }
  }
}

That entry allows python3 safe.py; python3 other.py is an allowlist miss. If a path-only entry for the same binary is also present, unmatched arguments can still fall back to that path-only entry. Omit the path-only entry when the goal is to restrict the binary to the declared arguments.

Entries saved by approval flows use an internal separator format for exact argv matching. Prefer the UI or approval flow to regenerate those entries instead of hand-editing the encoded value. If OpenClaw cannot parse argv for a command segment, entries with argPattern do not match.

Each allowlist entry supports:

Field	Meaning
pattern	Resolved binary path glob or bare command-name glob
argPattern	Optional argv regex; omitted entries are path-only
id	Stable UUID used for UI identity
source	Entry source, such as allow-always
commandText	Command text captured when an approval flow created the entry
lastUsedAt	Last-used timestamp
lastUsedCommand	Last command that matched
lastResolvedPath	Last resolved binary path

Auto-allow skill CLIs

When Auto-allow skill CLIs (autoAllowSkills) is enabled, executables referenced by known skills are treated as allowlisted on nodes (macOS node or headless node host). This uses skills.bins over the Gateway RPC to fetch the skill bin list. Disable this if you want strict manual allowlists.

- This is an **implicit convenience allowlist**, separate from manual path allowlist entries. - It is intended for trusted operator environments where Gateway and node are in the same trust boundary. - If you require strict explicit trust, keep `autoAllowSkills: false` and use manual path allowlist entries only.

Safe bins and approval forwarding

For safe bins (the stdin-only fast-path), interpreter binding details, and how to forward approval prompts to Slack/Discord/Telegram (or run them as native approval clients), see Exec approvals - advanced.

Control UI editing

Use the Control UI -> Nodes -> Exec approvals card to edit defaults, per-agent overrides, and allowlists. Pick a scope (Defaults or an agent), tweak the policy, add/remove allowlist patterns, then Save. The UI shows last-used metadata per pattern so you can keep the list tidy.

The target selector chooses Gateway (local approvals) or a Node. Nodes must advertise system.execApprovals.get/set (macOS app or headless node host). If a node does not advertise exec approvals yet, edit its local approvals file directly.

CLI: openclaw approvals supports gateway or node editing - see Approvals CLI.

Approval flow

When a prompt is required, the gateway broadcasts exec.approval.requested to operator clients. The Control UI and macOS app resolve it via exec.approval.resolve, then the gateway forwards the approved request to the node host.

For host=node, approval requests include a canonical systemRunPlan payload. The gateway uses that plan as the authoritative command/cwd/session context when forwarding approved system.run requests:

• The node exec path prepares one canonical plan up front.
• The approval record stores that plan and its binding metadata.
• Once approved, the final forwarded system.run call reuses the stored plan instead of trusting later caller edits.
• If the caller changes command, rawCommand, cwd, agentId, or sessionKey after the approval request was created, the gateway rejects the forwarded run as an approval mismatch.

System events and denials

Exec lifecycle posts an Exec finished system message to the agent's session after the node reports completion. OpenClaw can also emit an in-progress notice once an approval is granted, after tools.exec.approvalRunningNoticeMs elapses (default 10000, 0 disables it). Denied exec approvals are terminal for the host command: the command does not run.

• For main-agent async approvals with an originating session, OpenClaw posts the denial back into that session as an internal followup so the agent can stop waiting on the async command and avoid a missing-result repair.
• If there is no session or the session cannot be resumed, OpenClaw can still report a concise denial to the operator or direct chat route.
• Denials for subagent and cron sessions are not posted back into that session.

Gateway-host exec approvals emit the same completion lifecycle event. Approval-gated execs reuse the approval id to correlate the pending request with its completion/denial message (Exec finished (gateway id=...) / Exec denied (gateway id=...)).

Implications

• full is powerful; prefer allowlists when possible.
• ask keeps you in the loop while still allowing fast approvals.
• Per-agent allowlists prevent one agent's approvals from leaking into others.
• Approvals only apply to host exec requests from authorized senders. Unauthorized senders cannot issue /exec.
• /exec security=full is a session-level convenience for authorized operators and skips approvals by design. To hard-block host exec, set approvals security to deny or deny the exec tool via tool policy.
