Building a Team of AI Agents with OpenClaw

Hex Hex · · 11 min read

Most people start with one AI agent. That's fine — one agent handling your Slack, your tasks, your coding is already a force multiplier. But at some point you hit a wall. One agent can't be everywhere at once, and one personality doesn't fit every context.

OpenClaw solves this with multi-agent routing: multiple fully isolated agents running inside a single gateway process, each with its own workspace, persona, channel accounts, and session history. From the outside they look like a coordinated team. Under the hood they're cleanly separated — no cross-talk unless you explicitly enable it.

This guide walks you through how to build that team — from the concepts to real config examples to spawning ACP coding sessions.

What "one agent" actually means

In OpenClaw, an agent is a fully scoped runtime with its own:

  • Workspace — the directory where its files live: SOUL.md, AGENTS.md, USER.md, memory files, and any workspace-level skills
  • State directory (agentDir) — auth profiles, model registry, per-agent config
  • Session store — chat history under ~/.openclaw/agents/<agentId>/sessions/

Each agent reads from its own ~/.openclaw/agents/<agentId>/agent/auth-profiles.json. Credentials are not shared automatically. If two agents need the same credentials, you copy the file explicitly.

The default setup is single-agent: one agent with id main, workspace at ~/.openclaw/workspace. When you add more agents, they sit alongside main — same process, separate brains.

Why you'd want multiple agents

A few patterns that push people toward multi-agent setups:

  • Different channels, different personalities. Your work agent on Telegram should feel different from your personal agent on WhatsApp. Different SOUL.md, different model, different tool access.
  • Different people, same server. Multiple people can share one OpenClaw host while keeping their AI data fully isolated — each person gets their own agent, their own session history, their own credentials.
  • Specialization. One fast Sonnet agent for quick replies, one Opus agent for deep work. Route by channel or by specific contacts.
  • Security isolation. A sandboxed agent for untrusted channels (family groups, public bots) alongside an unsandboxed agent for your personal use.

Adding a second agent

The quickest path is the wizard: 

openclaw agents add coding
openclaw agents add social

Each command creates a workspace with the standard bootstrap files, a dedicated agentDir, and a session store. Then verify: 

openclaw agents list --bindings

How routing works

Messages are routed to agents via bindings. A binding matches an inbound message by channel, account, and peer (DM or group id), then sends it to the specified agentId.

Bindings are deterministic — most-specific match wins:

  1. Exact peer match (specific DM or group id)
  2. Parent peer match (thread inheritance)
  3. Guild + roles (Discord role routing)
  4. Guild-level (Discord server)
  5. Team-level (Slack team)
  6. Account-level (specific account id for a channel)
  7. Channel-wide fallback (accountId: "*")
  8. Default agent (first in list, or marked default: true)

If multiple bindings match at the same specificity, the first one in config order wins. Multiple match fields in a single binding use AND semantics — all specified fields must match.

Example: fast agent on WhatsApp, deep-work agent on Telegram

A clean two-agent split by channel: 

{
  agents: {
    list: [
      {
        id: "chat",
        name: "Everyday",
        workspace: "~/.openclaw/workspace-chat",
        model: "anthropic/claude-sonnet-4-5",
      },
      {
        id: "opus",
        name: "Deep Work",
        workspace: "~/.openclaw/workspace-opus",
        model: "anthropic/claude-opus-4-6",
      },
    ],
  },
  bindings: [
    { agentId: "chat", match: { channel: "whatsapp" } },
    { agentId: "opus", match: { channel: "telegram" } },
  ],
}

Every WhatsApp message hits the Sonnet agent. Every Telegram message hits Opus. Each has its own workspace, so they get different SOUL.md files — different personalities, different operating instructions.

Example: routing one DM to a different agent

Keep WhatsApp on the fast agent, but route one specific contact to Opus: 

{
  bindings: [
    {
      agentId: "opus",
      match: {
        channel: "whatsapp",
        peer: { kind: "direct", id: "+15551234567" },
      },
    },
    { agentId: "chat", match: { channel: "whatsapp" } },
  ],
}

Peer bindings always win over channel-wide rules, so order them first in the config.

Example: multiple Discord bots, multiple agents

Each Discord bot account maps to a unique accountId. Bind each to a different agent: 

{
  agents: {
    list: [
      { id: "main", workspace: "~/.openclaw/workspace-main" },
      { id: "coding", workspace: "~/.openclaw/workspace-coding" },
    ],
  },
  bindings: [
    { agentId: "main", match: { channel: "discord", accountId: "default" } },
    { agentId: "coding", match: { channel: "discord", accountId: "coding" } },
  ],
  channels: {
    discord: {
      accounts: {
        default: {
          token: "DISCORD_BOT_TOKEN_MAIN",
          guilds: {
            "111111111111111111": {
              channels: { "222222222222222222": { allow: true, requireMention: false } },
            },
          },
        },
        coding: {
          token: "DISCORD_BOT_TOKEN_CODING",
          guilds: {
            "111111111111111111": {
              channels: { "333333333333333333": { allow: true, requireMention: false } },
            },
          },
        },
      },
    },
  },
}

Two bot tokens, two agent brains, one gateway. The coding agent can have its SOUL.md tuned for technical work while the main agent handles general conversation.

Per-agent sandbox and tool restrictions

You can lock down specific agents without affecting others. This is useful for untrusted contexts — a public-facing bot or a family group chat shouldn't have the same tool access as your personal agent: 

{
  agents: {
    list: [
      {
        id: "personal",
        workspace: "~/.openclaw/workspace-personal",
        sandbox: { mode: "off" },
        // No tool restrictions
      },
      {
        id: "family",
        workspace: "~/.openclaw/workspace-family",
        sandbox: {
          mode: "all",
          scope: "agent",
          docker: {
            setupCommand: "apt-get update && apt-get install -y git curl",
          },
        },
        tools: {
          allow: ["read", "sessions_list", "sessions_history"],
          deny: ["exec", "write", "edit", "browser"],
        },
      },
    ],
  },
}

The family agent runs in a Docker sandbox, can only read files and list sessions — no exec, no writes, no browser access. The personal agent runs unrestricted on the host.

ACP coding sessions: agents that write code

OpenClaw supports ACP (Agent Client Protocol) — a way to run external coding harnesses like Claude Code, Codex, Gemini CLI, and Pi through your agent. ACP sessions are a different tier from the regular sub-agent runtime.

The practical difference:

  • Sub-agents: OpenClaw-native delegated runs. Use for general task delegation.
  • ACP sessions: External harness runtimes (Codex, Claude Code, etc.). Use when you need a full coding agent with file access and shell execution.

Starting an ACP session from chat

/acp spawn codex --mode persistent --thread auto

This creates a persistent Codex session and binds it to the current thread. Follow-up messages in that thread route to Codex until you close or unfocus it.

Spawning an ACP session programmatically

From inside an agent turn (e.g., a cron job or another agent): 

{
  task: "Open the repo and fix the failing tests",
  runtime: "acp",
  agentId: "codex",
  thread: true,
  mode: "session"
}

Set runtime: "acp" explicitly — it defaults to "subagent" otherwise.

Supported harnesses

The acpx backend (installed separately) supports these harness aliases:

  • pi
  • claude (Claude Code)
  • codex (OpenAI Codex)
  • opencode
  • gemini (Gemini CLI)
  • kimi

Install the backend plugin first: 

openclaw plugins install acpx
openclaw config set plugins.entries.acpx.enabled true

Then verify with /acp doctor.

Permission modes for ACP sessions

ACP sessions are non-interactive — there's no TTY to approve prompts. Set permissionMode appropriately: 

openclaw config set plugins.entries.acpx.config.permissionMode approve-all
openclaw config set plugins.entries.acpx.config.nonInteractivePermissions fail

The default (approve-reads) blocks write operations in ACP sessions. For coding agents that need to write files, set approve-all. Restart the gateway after changing these.

Persistent ACP bindings for channels

You can bind a Discord channel or Telegram topic permanently to an ACP session in your config: 

{
  bindings: [
    {
      type: "acp",
      agentId: "codex",
      match: {
        channel: "discord",
        accountId: "default",
        peer: { kind: "channel", id: "222222222222222222" },
      },
      acp: { label: "codex-main", mode: "persistent" },
    },
  ],
  channels: {
    discord: {
      threadBindings: {
        enabled: true,
        spawnAcpSessions: true,
      },
    },
  },
}

Messages in that Discord channel route directly to the persistent Codex session. It's like having a dedicated coding channel that always knows the full context of what you're building.

Agent-to-agent messaging

By default, agents cannot message each other — this is intentional for isolation. To enable it explicitly: 

{
  tools: {
    agentToAgent: {
      enabled: true,
      allow: ["main", "coding"],
    },
  },
}

Only agents listed in allow can communicate. This lets you build orchestration patterns — your main agent spawning a coding agent to handle a task, then receiving the result — while keeping the blast radius controlled.

Putting it together: a real team setup

Here's a representative setup — a main personal agent, a coding agent via ACP, and a sandboxed family agent: 

{
  agents: {
    list: [
      {
        id: "main",
        default: true,
        workspace: "~/.openclaw/workspace",
        model: "anthropic/claude-opus-4-6",
      },
      {
        id: "coding",
        workspace: "~/.openclaw/workspace-coding",
        model: "anthropic/claude-sonnet-4-5",
        runtime: {
          type: "acp",
          acp: { agent: "codex", mode: "persistent", cwd: "/workspace/repos" },
        },
      },
      {
        id: "family",
        workspace: "~/.openclaw/workspace-family",
        sandbox: { mode: "all", scope: "agent" },
        tools: {
          deny: ["exec", "write", "edit", "browser"],
        },
      },
    ],
  },
  bindings: [
    { agentId: "main", match: { channel: "telegram" } },
    {
      agentId: "coding",
      match: {
        channel: "discord",
        peer: { kind: "channel", id: "333333333333333333" },
      },
    },
    {
      agentId: "family",
      match: {
        channel: "whatsapp",
        peer: { kind: "group", id: "120363999999999999@g.us" },
      },
    },
    { agentId: "main", match: { channel: "whatsapp" } },
  ],
  tools: {
    agentToAgent: {
      enabled: true,
      allow: ["main", "coding"],
    },
  },
}

Three brains. Three workspaces. One gateway. Restart with openclaw gateway restart and you're running a team.

One thing people get wrong

Auth profiles are per-agent. If you add a second agent and wonder why it can't access your Slack or GitHub — it's because credentials aren't shared. Copy ~/.openclaw/agents/main/agent/auth-profiles.json to the new agent's agentDir, or re-run the relevant auth setup for that agent explicitly.

Similarly: never share the same agentDir between two agents. It causes session and auth collisions that are annoying to debug.

Final thoughts

The jump from one agent to a team isn't that big — it's mostly config. What changes is the mental model. You stop thinking about "my AI agent" as a single thing and start thinking about it as a staffing problem: who handles what, with what access, on what channel.

Once you've been running two or three agents for a week, going back to one feels like losing a team member.
