How to Set Up OpenClaw Group Messages

OpenClaw group behavior is about restraint. The group-messages docs focus on WhatsApp, but the underlying lesson is broader: an assistant in a shared space should wake up when invited, keep the thread separate from private DMs, and make it obvious who it is addressing. That is a much healthier model than letting every group message become agent fuel by default.

When this is the right move

Use group-message setup when the assistant needs to live in a shared chat but should stay mention-gated, scoped to a clear allowlist, and isolated from the owner's personal DM session. It is also the right approach when you want group-specific directives like verbose mode or trace mode without polluting your direct chat context.

The practical workflow

1. Decide whether the group should be mention-only or always-on, and start with mention mode unless you have a very strong reason not to.
2. Set the group policy and allowlist rules so the bot only wakes for the senders and groups you actually trust.
3. Add mention patterns for names or numbers only when the platform needs that extra help beyond canonical mentions.
4. Use the owner-only /activation command inside the group when you need to change behavior for that group without affecting others.
5. Test group-specific directives such as /verbose on or /trace on as standalone messages to confirm the session is truly group-scoped.

Grounded command or config pattern

The official docs show a WhatsApp example that captures the main pieces: mention gating, history limits, and mention patterns.

{
  channels: {
    whatsapp: {
      groups: {
        "*": { requireMention: true },
      },
    },
  },
  agents: {
    list: [
      {
        id: "main",
        groupChat: {
          historyLimit: 50,
          mentionPatterns: ["@?openclaw", "\+?15555550123"],
        },
      },
    ],
  },
}

/activation mention
/activation always

The docs also explain that group session keys stay separate from personal DMs, pending-only context gets injected as a recent-message block, and every group batch ends with a sender marker so the agent can address the right person.

Operator notes

Group policy, group allowlists, mention rules, and activation mode all work together. The docs say groupPolicy defaults to allowlist behavior on the WhatsApp path they describe, and that heartbeats are intentionally skipped for groups to avoid noisy broadcasts. That is a good default philosophy even if you later adopt similar patterns on other chat surfaces.

Rollout approach

For group messages, keep the first rollout narrow: one group, one owner, mention-only activation, and one visible test. Groups feel social, so mistakes feel public. It is much better to prove that the bot wakes only when asked than to apologize after it replies in the wrong place three times in a row.

Common mistake

The common mistake is treating the command or config key as the whole feature. The command starts the workflow, but the surrounding state is what keeps it reliable: config validation, auth, pairing, permissions, logs, and one small verification step. If those pieces are skipped, the next failure looks random even when OpenClaw is behaving exactly as configured.

Maintenance rhythm

Once this is working, write down the exact command, config path, or approval decision you used. Future you will not remember the tiny detail that made the setup safe. A short note in the workspace or runbook is cheaper than rediscovering the same behavior during an outage, especially after updates or host changes.

Safety checks

Do not turn on always mode just because mention handling is inconvenient. The docs still expect the agent to return the exact silent token when it has nothing meaningful to add, and that is a subtle behavior to trust too early in a noisy group. Start with mentions, explicit allowlists, and separate group sessions.

How to verify it worked

Send an @mention in the group and confirm the reply references the correct sender. Then send a group-specific directive such as /verbose on and make sure it affects only that group session. Finally, open your personal DM and confirm the state there is unchanged. If those checks pass, the isolation model is doing its job.

If you want the operator version with sharper checklists, safer defaults, and fewer “why is this broken?” afternoons, The OpenClaw Playbook is the shortcut I would hand to a serious OpenClaw owner.
