# Configuration Reference

Core config reference for `~/.kaijibot/kaijibot.json`. For a task-oriented overview, see [Configuration](/gateway/configuration).

This page covers the main KaijiBot config surfaces and links out when a subsystem has its own deeper reference. It does **not** try to inline every channel/plugin-owned command catalog or every deep memory/QMD knob on one page.

Code truth:

- `kaijibot config schema` prints the live JSON Schema used for validation and Control UI, with bundled/plugin/channel metadata merged in when available
- `config.schema.lookup` returns one path-scoped schema node for drill-down tooling
- `pnpm config:docs:check` / `pnpm config:docs:gen` validate the config-doc baseline hash against the current schema surface

Dedicated deep references:

- [Memory configuration reference](/reference/memory-config) for `agents.defaults.memorySearch.*`, `memory.qmd.*`, `memory.citations`, and dreaming config under `plugins.entries.memory-core.config.dreaming`
- [Slash Commands](/tools/slash-commands) for the current built-in + bundled command catalog
- owning channel/plugin pages for channel-specific command surfaces

Config format is **JSON5** (comments + trailing commas allowed). All fields are optional — KaijiBot uses safe defaults when omitted.

---

## Channels

Each channel starts automatically when its config section exists (unless `enabled: false`).

### DM and group access

All channels support DM policies and group policies:

| DM policy           | Behavior                                                        |
| ------------------- | --------------------------------------------------------------- |
| `pairing` (default) | Unknown senders get a one-time pairing code; owner must approve |
| `allowlist`         | Only senders in `allowFrom` (or paired allow store)             |
| `open`              | Allow all inbound DMs (requires `allowFrom: ["*"]`)             |
| `disabled`          | Ignore all inbound DMs                                          |

| Group policy          | Behavior                                               |
| --------------------- | ------------------------------------------------------ |
| `allowlist` (default) | Only groups matching the configured allowlist          |
| `open`                | Bypass group allowlists (mention-gating still applies) |
| `disabled`            | Block all group/room messages                          |

<Note>
`channels.defaults.groupPolicy` sets the default when a provider's `groupPolicy` is unset.
Pairing codes expire after 1 hour. Pending DM pairing requests are capped at **3 per channel**.
If a provider block is missing entirely (`channels.<provider>` absent), runtime group policy falls back to `allowlist` (fail-closed) with a startup warning.
</Note>

### Channel model overrides

Use `channels.modelByChannel` to pin specific channel IDs to a model. Values accept `provider/model` or configured model aliases. The channel mapping applies when a session does not already have a model override (for example, set via `/model`).

```json5
{
  channels: {
    modelByChannel: {
      discord: {
        "123456789012345678": "anthropic/claude-opus-4-6",
      },
      slack: {
        C1234567890: "openai/gpt-4.1",
      },
      telegram: {
        "-1001234567890": "openai/gpt-4.1-mini",
        "-1001234567890:topic:99": "anthropic/claude-sonnet-4-6",
      },
    },
  },
}
```

### Channel defaults and heartbeat

Use `channels.defaults` for shared group-policy and heartbeat behavior across providers:

```json5
{
  channels: {
    defaults: {
      groupPolicy: "allowlist", // open | allowlist | disabled
      contextVisibility: "all", // all | allowlist | allowlist_quote
      heartbeat: {
        showOk: false,
        showAlerts: true,
        useIndicator: true,
      },
    },
  },
}
```

- `channels.defaults.groupPolicy`: fallback group policy when a provider-level `groupPolicy` is unset.
- `channels.defaults.contextVisibility`: default supplemental context visibility mode for all channels. Values: `all` (default, include all quoted/thread/history context), `allowlist` (only include context from allowlisted senders), `allowlist_quote` (same as allowlist but keep explicit quote/reply context). Per-channel override: `channels.<channel>.contextVisibility`.
- `channels.defaults.heartbeat.showOk`: include healthy channel statuses in heartbeat output.
- `channels.defaults.heartbeat.showAlerts`: include degraded/error statuses in heartbeat output.
- `channels.defaults.heartbeat.useIndicator`: render compact indicator-style heartbeat output.

### WhatsApp

WhatsApp runs through the gateway's web channel (Baileys Web). It starts automatically when a linked session exists.

```json5
{
  channels: {
    whatsapp: {
      dmPolicy: "pairing", // pairing | allowlist | open | disabled
      allowFrom: ["+15555550123", "+447700900123"],
      textChunkLimit: 4000,
      chunkMode: "length", // length | newline
      mediaMaxMb: 50,
      sendReadReceipts: true, // blue ticks (false in self-chat mode)
      groups: {
        "*": { requireMention: true },
      },
      groupPolicy: "allowlist",
      groupAllowFrom: ["+15551234567"],
    },
  },
  web: {
    enabled: true,
    heartbeatSeconds: 60,
    reconnect: {
      initialMs: 2000,
      maxMs: 120000,
      factor: 1.4,
      jitter: 0.2,
      maxAttempts: 0,
    },
  },
}
```

<Accordion title="Multi-account WhatsApp">

```json5
{
  channels: {
    whatsapp: {
      accounts: {
        default: {},
        personal: {},
        biz: {
          // authDir: "~/.kaijibot/credentials/whatsapp/biz",
        },
      },
    },
  },
}
```

- Outbound commands default to account `default` if present; otherwise the first configured account id (sorted).
- Optional `channels.whatsapp.defaultAccount` overrides that fallback default account selection when it matches a configured account id.
- Legacy single-account Baileys auth dir is migrated by `kaijibot doctor` into `whatsapp/default`.
- Per-account overrides: `channels.whatsapp.accounts.<id>.sendReadReceipts`, `channels.whatsapp.accounts.<id>.dmPolicy`, `channels.whatsapp.accounts.<id>.allowFrom`.

</Accordion>

### Telegram

```json5
{
  channels: {
    telegram: {
      enabled: true,
      botToken: "your-bot-token",
      dmPolicy: "pairing",
      allowFrom: ["tg:123456789"],
      groups: {
        "*": { requireMention: true },
        "-1001234567890": {
          allowFrom: ["@admin"],
          systemPrompt: "Keep answers brief.",
          topics: {
            "99": {
              requireMention: false,
              skills: ["search"],
              systemPrompt: "Stay on topic.",
            },
          },
        },
      },
      customCommands: [
        { command: "backup", description: "Git backup" },
        { command: "generate", description: "Create an image" },
      ],
      historyLimit: 50,
      replyToMode: "first", // off | first | all | batched
      linkPreview: true,
      streaming: "partial", // off | partial | block | progress (default: off; opt in explicitly to avoid preview-edit rate limits)
      actions: { reactions: true, sendMessage: true },
      reactionNotifications: "own", // off | own | all
      mediaMaxMb: 100,
      retry: {
        attempts: 3,
        minDelayMs: 400,
        maxDelayMs: 30000,
        jitter: 0.1,
      },
      network: {
        autoSelectFamily: true,
        dnsResultOrder: "ipv4first",
      },
      proxy: "socks5://localhost:9050",
      webhookUrl: "https://example.com/telegram-webhook",
      webhookSecret: "secret",
      webhookPath: "/telegram-webhook",
    },
  },
}
```

- Bot token: `channels.telegram.botToken` or `channels.telegram.tokenFile` (regular file only; symlinks rejected), with `TELEGRAM_BOT_TOKEN` as fallback for the default account.
- Optional `channels.telegram.defaultAccount` overrides default account selection when it matches a configured account id.
- In multi-account setups (2+ account ids), set an explicit default (`channels.telegram.defaultAccount` or `channels.telegram.accounts.default`) to avoid fallback routing; `kaijibot doctor` warns when this is missing or invalid.
- `configWrites: false` blocks Telegram-initiated config writes (supergroup ID migrations, `/config set|unset`).
- Top-level `bindings[]` entries with `type: "acp"` configure persistent ACP bindings for forum topics (use canonical `chatId:topic:topicId` in `match.peer.id`). Field semantics are shared in [ACP Agents](/tools/acp-agents#channel-specific-settings).
- Telegram stream previews use `sendMessage` + `editMessageText` (works in direct and group chats).
- Retry policy: see [Retry policy](/concepts/retry).

```

- Token: `channels.discord.token`, with `DISCORD_BOT_TOKEN` as fallback for the default account.
- Direct outbound calls that provide an explicit Discord `token` use that token for the call; account retry/policy settings still come from the selected account in the active runtime snapshot.
- Optional `channels.discord.defaultAccount` overrides default account selection when it matches a configured account id.
- Use `user:<id>` (DM) or `channel:<id>` (guild channel) for delivery targets; bare numeric IDs are rejected.
- Guild slugs are lowercase with spaces replaced by `-`; channel keys use the slugged name (no `#`). Prefer guild IDs.
- Bot-authored messages are ignored by default. `allowBots: true` enables them; use `allowBots: "mentions"` to only accept bot messages that mention the bot (own messages still filtered).
- `channels.discord.guilds.<id>.ignoreOtherMentions` (and channel overrides) drops messages that mention another user or role but not the bot (excluding @everyone/@here).
- `maxLinesPerMessage` (default 17) splits tall messages even when under 2000 chars.
- `channels.discord.threadBindings` controls Discord thread-bound routing:
  - `enabled`: Discord override for thread-bound session features (`/focus`, `/unfocus`, `/agents`, `/session idle`, `/session max-age`, and bound delivery/routing)
  - `idleHours`: Discord override for inactivity auto-unfocus in hours (`0` disables)
  - `maxAgeHours`: Discord override for hard max age in hours (`0` disables)
  - `spawnSubagentSessions`: opt-in switch for `sessions_spawn({ thread: true })` auto thread creation/binding
- Top-level `bindings[]` entries with `type: "acp"` configure persistent ACP bindings for channels and threads (use channel/thread id in `match.peer.id`). Field semantics are shared in [ACP Agents](/tools/acp-agents#channel-specific-settings).
- `channels.discord.ui.components.accentColor` sets the accent color for Discord components v2 containers.
- `channels.discord.voice` enables Discord voice channel conversations and optional auto-join + TTS overrides.
- `channels.discord.voice.daveEncryption` and `channels.discord.voice.decryptionFailureTolerance` pass through to `@discordjs/voice` DAVE options (`true` and `24` by default).
- KaijiBot additionally attempts voice receive recovery by leaving/rejoining a voice session after repeated decrypt failures.
- `channels.discord.streaming` is the canonical stream mode key. Legacy `streamMode` and boolean `streaming` values are auto-migrated.
- `channels.discord.autoPresence` maps runtime availability to bot presence (healthy => online, degraded => idle, exhausted => dnd) and allows optional status text overrides.
- `channels.discord.dangerouslyAllowNameMatching` re-enables mutable name/tag matching (break-glass compatibility mode).
- `channels.discord.execApprovals`: Discord-native exec approval delivery and approver authorization.
  - `enabled`: `true`, `false`, or `"auto"` (default). In auto mode, exec approvals activate when approvers can be resolved from `approvers` or `commands.ownerAllowFrom`.
  - `approvers`: Discord user IDs allowed to approve exec requests. Falls back to `commands.ownerAllowFrom` when omitted.
  - `agentFilter`: optional agent ID allowlist. Omit to forward approvals for all agents.
  - `sessionFilter`: optional session key patterns (substring or regex).
  - `target`: where to send approval prompts. `"dm"` (default) sends to approver DMs, `"channel"` sends to the originating channel, `"both"` sends to both. When target includes `"channel"`, buttons are only usable by resolved approvers.
  - `cleanupAfterResolve`: when `true`, deletes approval DMs after approval, denial, or timeout.

**Reaction notification modes:** `off` (none), `own` (bot's messages, default), `all` (all messages), `allowlist` (from `guilds.<id>.users` on all messages).

### Google Chat

```json5
{
  channels: {
    googlechat: {
      enabled: true,
      serviceAccountFile: "/path/to/service-account.json",
      audienceType: "app-url", // app-url | project-number
      audience: "https://gateway.example.com/googlechat",
      webhookPath: "/googlechat",
      botUser: "users/1234567890",
      dm: {
        enabled: true,
        policy: "pairing",
        allowFrom: ["users/1234567890"],
      },
      groupPolicy: "allowlist",
      groups: {
        "spaces/AAAA": { allow: true, requireMention: true },
      },
      actions: { reactions: true },
      typingIndicator: "message",
      mediaMaxMb: 20,
    },
  },
}
```

- Service account JSON: inline (`serviceAccount`) or file-based (`serviceAccountFile`).
- Service account SecretRef is also supported (`serviceAccountRef`).
- Env fallbacks: `GOOGLE_CHAT_SERVICE_ACCOUNT` or `GOOGLE_CHAT_SERVICE_ACCOUNT_FILE`.
- Use `spaces/<spaceId>` or `users/<userId>` for delivery targets.
- `channels.googlechat.dangerouslyAllowNameMatching` re-enables mutable email principal matching (break-glass compatibility mode).

### Slack

```json5
{
  channels: {
    slack: {
      enabled: true,
      botToken: "xoxb-...",
      appToken: "xapp-...",
      dmPolicy: "pairing",
      allowFrom: ["U123", "U456", "*"],
      dm: { enabled: true, groupEnabled: false, groupChannels: ["G123"] },
      channels: {
        C123: { allow: true, requireMention: true, allowBots: false },
        "#general": {
          allow: true,
          requireMention: true,
          allowBots: false,
          users: ["U123"],
          skills: ["docs"],
          systemPrompt: "Short answers only.",
        },
      },
      historyLimit: 50,
      allowBots: false,
      reactionNotifications: "own",
      reactionAllowlist: ["U123"],
      replyToMode: "off", // off | first | all | batched
      thread: {
        historyScope: "thread", // thread | channel
        inheritParent: false,
      },
      actions: {

        messages: true,
        pins: true,
        memberInfo: true,
        emojiList: true,
      },
      slashCommand: {
        enabled: true,
        name: "kaijibot",
        sessionPrefix: "slack:slash",
        ephemeral: true,
      },
      typingReaction: "hourglass_flowing_sand",
      textChunkLimit: 4000,
      chunkMode: "length",
      streaming: {
        mode: "partial", // off | partial | block | progress
        nativeTransport: true, // use Slack native streaming API when mode=partial
      },
      mediaMaxMb: 20,
      execApprovals: {
        enabled: "auto", // true | false | "auto"
        approvers: ["U123"],
        agentFilter: ["default"],
        sessionFilter: ["slack:"],
        target: "dm", // dm | channel | both
      },
    },
  },
}
```

- **Socket mode** requires both `botToken` and `appToken` (`SLACK_BOT_TOKEN` + `SLACK_APP_TOKEN` for default account env fallback).
- **HTTP mode** requires `botToken` plus `signingSecret` (at root or per-account).
- `botToken`, `appToken`, `signingSecret`, and `userToken` accept plaintext
  strings or SecretRef objects.
- Slack account snapshots expose per-credential source/status fields such as
  `botTokenSource`, `botTokenStatus`, `appTokenStatus`, and, in HTTP mode,
  `signingSecretStatus`. `configured_unavailable` means the account is
  configured through SecretRef but the current command/runtime path could not
  resolve the secret value.
- `configWrites: false` blocks Slack-initiated config writes.
- Optional `channels.slack.defaultAccount` overrides default account selection when it matches a configured account id.
- `channels.slack.streaming.mode` is the canonical Slack stream mode key. `channels.slack.streaming.nativeTransport` controls Slack's native streaming transport. Legacy `streamMode`, boolean `streaming`, and `nativeStreaming` values are auto-migrated.
- Use `user:<id>` (DM) or `channel:<id>` for delivery targets.

**Reaction notification modes:** `off`, `own` (default), `all`, `allowlist` (from `reactionAllowlist`).

**Thread session isolation:** `thread.historyScope` is per-thread (default) or shared across channel. `thread.inheritParent` copies parent channel transcript to new threads.

- Slack native streaming plus the Slack assistant-style "is typing..." thread status require a reply thread target. Top-level DMs stay off-thread by default, so they use `typingReaction` or normal delivery instead of the thread-style preview.
- `typingReaction` adds a temporary reaction to the inbound Slack message while a reply is running, then removes it on completion. Use a Slack emoji shortcode such as `"hourglass_flowing_sand"`.
- `channels.slack.execApprovals`: Slack-native exec approval delivery and approver authorization. Same schema as Discord: `enabled` (`true`/`false`/`"auto"`), `approvers` (Slack user IDs), `agentFilter`, `sessionFilter`, and `target` (`"dm"`, `"channel"`, or `"both"`).

| Action group | Default | Notes                  |
| ------------ | ------- | ---------------------- |
| reactions    | enabled | React + list reactions |
| messages     | enabled | Read/send/edit/delete  |
| pins         | enabled | Pin/unpin/list         |
| memberInfo   | enabled | Member info            |
| emojiList    | enabled | Custom emoji list      |

### Mattermost

Mattermost ships as a plugin: `kaijibot plugins install @kaijibot/mattermost`.

```json5
{
  channels: {
    mattermost: {
      enabled: true,
      botToken: "mm-token",
      baseUrl: "https://chat.example.com",
      dmPolicy: "pairing",
      chatmode: "oncall", // oncall | onmessage | onchar
      oncharPrefixes: [">", "!"],
      groups: {
        "*": { requireMention: true },
        "team-channel-id": { requireMention: false },
      },
      commands: {
        native: true, // opt-in
        nativeSkills: true,
        callbackPath: "/api/channels/mattermost/command",
        // Optional explicit URL for reverse-proxy/public deployments
        callbackUrl: "https://gateway.example.com/api/channels/mattermost/command",
      },
      textChunkLimit: 4000,
      chunkMode: "length",
    },
  },
}
```

Chat modes: `oncall` (respond on @-mention, default), `onmessage` (every message), `onchar` (messages starting with trigger prefix).

When Mattermost native commands are enabled:

- `commands.callbackPath` must be a path (for example `/api/channels/mattermost/command`), not a full URL.
- `commands.callbackUrl` must resolve to the KaijiBot gateway endpoint and be reachable from the Mattermost server.
- Native slash callbacks are authenticated with the per-command tokens returned
  by Mattermost during slash command registration. If registration fails or no
  commands are activated, KaijiBot rejects callbacks with
  `Unauthorized: invalid command token.`
- For private/tailnet/internal callback hosts, Mattermost may require
  `ServiceSettings.AllowedUntrustedInternalConnections` to include the callback host/domain.
  Use host/domain values, not full URLs.
- `channels.mattermost.configWrites`: allow or deny Mattermost-initiated config writes.
- `channels.mattermost.requireMention`: require `@mention` before replying in channels.
- `channels.mattermost.groups.<channelId>.requireMention`: per-channel mention-gating override (`"*"` for default).
- Optional `channels.mattermost.defaultAccount` overrides default account selection when it matches a configured account id.

### Signal

```json5
{
  channels: {
    signal: {
      enabled: true,
      account: "+15555550123", // optional account binding
      dmPolicy: "pairing",
      allowFrom: ["+15551234567", "uuid:123e4567-e89b-12d3-a456-426614174000"],
      configWrites: true,
      reactionNotifications: "own", // off | own | all | allowlist
      reactionAllowlist: ["+15551234567", "uuid:123e4567-e89b-12d3-a456-426614174000"],
      historyLimit: 50,
    },
  },
}
```

**Reaction notification modes:** `off`, `own` (default), `all`, `allowlist` (from `reactionAllowlist`).

- `channels.signal.account`: pin channel startup to a specific Signal account identity.
- `channels.signal.configWrites`: allow or deny Signal-initiated config writes.
- Optional `channels.signal.defaultAccount` overrides default account selection when it matches a configured account id.

### BlueBubbles

BlueBubbles is the recommended iMessage path (plugin-backed, configured under `channels.bluebubbles`).

```json5
{
  channels: {
    bluebubbles: {
      enabled: true,
      dmPolicy: "pairing",
      // serverUrl, password, webhookPath, group controls, and advanced actions:
      // see /channels/bluebubbles
    },
  },
}
```

- Core key paths covered here: `channels.bluebubbles`, `channels.bluebubbles.dmPolicy`.
- Optional `channels.bluebubbles.defaultAccount` overrides default account selection when it matches a configured account id.
- Top-level `bindings[]` entries with `type: "acp"` can bind BlueBubbles conversations to persistent ACP sessions. Use a BlueBubbles handle or target string (`chat_id:*`, `chat_guid:*`, `chat_identifier:*`) in `match.peer.id`. Shared field semantics: [ACP Agents](/tools/acp-agents#channel-specific-settings).
- Full BlueBubbles channel configuration is documented in [BlueBubbles](/channels/bluebubbles).

### iMessage

KaijiBot spawns `imsg rpc` (JSON-RPC over stdio). No daemon or port required.

```json5
{
  channels: {
    imessage: {
      enabled: true,
      cliPath: "imsg",
      dbPath: "~/Library/Messages/chat.db",
      remoteHost: "user@gateway-host",
      dmPolicy: "pairing",
      allowFrom: ["+15555550123", "user@example.com", "chat_id:123"],
      historyLimit: 50,
      includeAttachments: false,
      attachmentRoots: ["/Users/*/Library/Messages/Attachments"],
      remoteAttachmentRoots: ["/Users/*/Library/Messages/Attachments"],
      mediaMaxMb: 16,
      service: "auto",
      region: "US",
    },
  },
}
```

- Optional `channels.imessage.defaultAccount` overrides default account selection when it matches a configured account id.

- Requires Full Disk Access to the Messages DB.
- Prefer `chat_id:<id>` targets. Use `imsg chats --limit 20` to list chats.
- `cliPath` can point to an SSH wrapper; set `remoteHost` (`host` or `user@host`) for SCP attachment fetching.
- `attachmentRoots` and `remoteAttachmentRoots` restrict inbound attachment paths (default: `/Users/*/Library/Messages/Attachments`).
- SCP uses strict host-key checking, so ensure the relay host key already exists in `~/.ssh/known_hosts`.
- `channels.imessage.configWrites`: allow or deny iMessage-initiated config writes.
- Top-level `bindings[]` entries with `type: "acp"` can bind iMessage conversations to persistent ACP sessions. Use a normalized handle or explicit chat target (`chat_id:*`, `chat_guid:*`, `chat_identifier:*`) in `match.peer.id`. Shared field semantics: [ACP Agents](/tools/acp-agents#channel-specific-settings).

<Accordion title="iMessage SSH wrapper example">

```bash
#!/usr/bin/env bash
exec ssh -T gateway-host imsg "$@"
```

### Matrix

Matrix is extension-backed and configured under `channels.matrix`.

```json5
{
  channels: {
    matrix: {
      enabled: true,
      homeserver: "https://matrix.example.org",
      accessToken: "syt_bot_xxx",
      proxy: "http://127.0.0.1:7890",
      encryption: true,
      initialSyncLimit: 20,
      defaultAccount: "ops",
      accounts: {
        ops: {
          name: "Ops",
          userId: "@ops:example.org",
          accessToken: "syt_ops_xxx",
        },
        alerts: {
          userId: "@alerts:example.org",
          password: "secret",
          proxy: "http://127.0.0.1:7891",
        },
      },
    },
  },
}
```

- Token auth uses `accessToken`; password auth uses `userId` + `password`.
- `channels.matrix.proxy` routes Matrix HTTP traffic through an explicit HTTP(S) proxy. Named accounts can override it with `channels.matrix.accounts.<id>.proxy`.
- `channels.matrix.network.dangerouslyAllowPrivateNetwork` allows private/internal homeservers. `proxy` and this network opt-in are independent controls.
- `channels.matrix.defaultAccount` selects the preferred account in multi-account setups.
- `channels.matrix.autoJoin` defaults to `off`, so invited rooms and fresh DM-style invites are ignored until you set `autoJoin: "allowlist"` with `autoJoinAllowlist` or `autoJoin: "always"`.
- `channels.matrix.execApprovals`: Matrix-native exec approval delivery and approver authorization.
  - `enabled`: `true`, `false`, or `"auto"` (default). In auto mode, exec approvals activate when approvers can be resolved from `approvers` or `commands.ownerAllowFrom`.
  - `approvers`: Matrix user IDs (e.g. `@owner:example.org`) allowed to approve exec requests.
  - `agentFilter`: optional agent ID allowlist. Omit to forward approvals for all agents.
  - `sessionFilter`: optional session key patterns (substring or regex).
  - `target`: where to send approval prompts. `"dm"` (default), `"channel"` (originating room), or `"both"`.
  - Per-account overrides: `channels.matrix.accounts.<id>.execApprovals`.
- `channels.matrix.dm.sessionScope` controls how Matrix DMs group into sessions: `per-user` (default) shares by routed peer, while `per-room` isolates each DM room.
- Matrix status probes and live directory lookups use the same proxy policy as runtime traffic.
- Full Matrix configuration, targeting rules, and setup examples are documented in [Matrix](/channels/matrix).

### Microsoft Teams

Microsoft Teams is extension-backed and configured under `channels.msteams`.

```json5
{
  channels: {
    msteams: {
      enabled: true,
      configWrites: true,
      // appId, appPassword, tenantId, webhook, team/channel policies:
      // see /channels/msteams
    },
  },
}
```

- Core key paths covered here: `channels.msteams`, `channels.msteams.configWrites`.
- Full Teams config (credentials, webhook, DM/group policy, per-team/per-channel overrides) is documented in [Microsoft Teams](/channels/msteams).

### IRC

IRC is extension-backed and configured under `channels.irc`.

```json5
{
  channels: {
    irc: {
      enabled: true,
      dmPolicy: "pairing",
      configWrites: true,
      nickserv: {
        enabled: true,
        service: "NickServ",
        password: "${IRC_NICKSERV_PASSWORD}",
        register: false,
        registerEmail: "bot@example.com",
      },
    },
  },
}
```

- Core key paths covered here: `channels.irc`, `channels.irc.dmPolicy`, `channels.irc.configWrites`, `channels.irc.nickserv.*`.
- Optional `channels.irc.defaultAccount` overrides default account selection when it matches a configured account id.
- Full IRC channel configuration (host/port/TLS/channels/allowlists/mention gating) is documented in [IRC](/channels/irc).

### Multi-account (all channels)

Run multiple accounts per channel (each with its own `accountId`):

```json5
{
  channels: {
    telegram: {
      accounts: {
        default: {
          name: "Primary bot",
          botToken: "123456:ABC...",
        },
        alerts: {
          name: "Alerts bot",
          botToken: "987654:XYZ...",
        },
      },
    },
  },
}
```

- `default` is used when `accountId` is omitted (CLI + routing).
- Env tokens only apply to the **default** account.
- Base channel settings apply to all accounts unless overridden per account.
- Use `bindings[].match.accountId` to route each account to a different agent.
- If you add a non-default account via `kaijibot channels add` (or channel onboarding) while still on a single-account top-level channel config, KaijiBot promotes account-scoped top-level single-account values into the channel account map first so the original account keeps working. Most channels move them into `channels.<channel>.accounts.default`; Matrix can preserve an existing matching named/default target instead.
- Existing channel-only bindings (no `accountId`) keep matching the default account; account-scoped bindings remain optional.
- `kaijibot doctor --fix` also repairs mixed shapes by moving account-scoped top-level single-account values into the promoted account chosen for that channel. Most channels use `accounts.default`; Matrix can preserve an existing matching named/default target instead.

### Other extension channels

Many extension channels are configured as `channels.<id>` and documented in their dedicated channel pages (for example Feishu, Matrix, LINE, Nostr, Zalo, Nextcloud Talk, Synology Chat, and Twitch).
See the full channel index: [Channels](/channels).

### Group chat mention gating

Group messages default to **require mention** (metadata mention or safe regex patterns). Applies to WhatsApp, Telegram, Discord, Google Chat, and iMessage group chats.

**Mention types:**

- **Metadata mentions**: Native platform @-mentions. Ignored in WhatsApp self-chat mode.
- **Text patterns**: Safe regex patterns in `agents.list[].groupChat.mentionPatterns`. Invalid patterns and unsafe nested repetition are ignored.
- Mention gating is enforced only when detection is possible (native mentions or at least one pattern).

```json5
{
  messages: {
    groupChat: { historyLimit: 50 },
  },
  agents: {
    list: [{ id: "main", groupChat: { mentionPatterns: ["@kaijibot", "kaijibot"] } }],
  },
}
```

`messages.groupChat.historyLimit` sets the global default. Channels can override with `channels.<channel>.historyLimit` (or per-account). Set `0` to disable.

#### DM history limits

```json5
{
  channels: {
    telegram: {
      dmHistoryLimit: 30,
      dms: {
        "123456789": { historyLimit: 50 },
      },
    },
  },
}
```

Resolution: per-DM override → provider default → no limit (all retained).

Supported: `telegram`, `whatsapp`, `discord`, `slack`, `signal`, `imessage`, `msteams`.

#### Self-chat mode

Include your own number in `allowFrom` to enable self-chat mode (ignores native @-mentions, only responds to text patterns):

```json5
{
  channels: {
    whatsapp: {
      allowFrom: ["+15555550123"],
      groups: { "*": { requireMention: true } },
    },
  },
  agents: {
    list: [
      {
        id: "main",
        groupChat: { mentionPatterns: ["reisponde", "@kaijibot"] },
      },
    ],
  },
}
```

### Commands (chat command handling)

```json5
{
  commands: {
    native: "auto", // register native commands when supported
    nativeSkills: "auto", // register native skill commands when supported
    text: true, // parse /commands in chat messages
    bash: false, // allow ! (alias: /bash)
    bashForegroundMs: 2000,
    config: false, // allow /config
    mcp: false, // allow /mcp
    plugins: false, // allow /plugins
    debug: false, // allow /debug
    restart: true, // allow /restart + gateway restart tool
    ownerAllowFrom: ["discord:123456789012345678"],
    ownerDisplay: "raw", // raw | hash
    ownerDisplaySecret: "${OWNER_ID_HASH_SECRET}",
    allowFrom: {
      "*": ["user1"],
      discord: ["user:123"],
    },
    useAccessGroups: true,
  },
}
```

<Accordion title="Command details">

- This block configures command surfaces. For the current built-in + bundled command catalog, see [Slash Commands](/tools/slash-commands).
- This page is a **config-key reference**, not the full command catalog. Channel/plugin-owned commands such as QQ Bot `/bot-ping` `/bot-help` `/bot-logs`, LINE `/card`, device-pair `/pair`, memory `/dreaming`, phone-control `/phone`, and Talk `/voice` are documented in their channel/plugin pages plus [Slash Commands](/tools/slash-commands).
- Text commands must be **standalone** messages with leading `/`.
- `native: "auto"` turns on native commands for Discord/Telegram, leaves Slack off.
- `nativeSkills: "auto"` turns on native skill commands for Discord/Telegram, leaves Slack off.
- Override per channel: `channels.discord.commands.native` (bool or `"auto"`). `false` clears previously registered commands.
- Override native skill registration per channel with `channels.<provider>.commands.nativeSkills`.
- `channels.telegram.customCommands` adds extra Telegram bot menu entries.
- `bash: true` enables `! <cmd>` for host shell. Requires `tools.elevated.enabled` and sender in `tools.elevated.allowFrom.<channel>`.
- `config: true` enables `/config` (reads/writes `kaijibot.json`). For gateway `chat.send` clients, persistent `/config set|unset` writes also require `operator.admin`; read-only `/config show` stays available to normal write-scoped operator clients.
- `mcp: true` enables `/mcp` for KaijiBot-managed MCP server config under `mcp.servers`.
- `plugins: true` enables `/plugins` for plugin discovery, install, and enable/disable controls.
- `channels.<provider>.configWrites` gates config mutations per channel (default: true).
- For multi-account channels, `channels.<provider>.accounts.<id>.configWrites` also gates writes that target that account (for example `/allowlist --config --account <id>` or `/config set channels.<provider>.accounts.<id>...`).
- `restart: false` disables `/restart` and gateway restart tool actions. Default: `true`.
- `ownerAllowFrom` is the explicit owner allowlist for owner-only commands/tools. It is separate from `allowFrom`.
- `ownerDisplay: "hash"` hashes owner ids in the system prompt. Set `ownerDisplaySecret` to control hashing.
- `allowFrom` is per-provider. When set, it is the **only** authorization source (channel allowlists/pairing and `useAccessGroups` are ignored).
- `useAccessGroups: false` allows commands to bypass access-group policies when `allowFrom` is not set.

## Agent defaults

### `agents.defaults.workspace`

Default: `~/.kaijibot/workspace`.

```json5
{
  agents: { defaults: { workspace: "~/.kaijibot/workspace" } },
}
```

### `agents.defaults.repoRoot`

Optional repository root shown in the system prompt's Runtime line. If unset, KaijiBot auto-detects by walking upward from the workspace.

```json5
{
  agents: { defaults: { repoRoot: "~/Projects/kaijibot" } },
}
```

### `agents.defaults.skills`

Optional default skill allowlist for agents that do not set
`agents.list[].skills`.

```json5
{
  agents: {
    defaults: { skills: ["github", "weather"] },
    list: [
      { id: "writer" }, // inherits github, weather
      { id: "docs", skills: ["docs-search"] }, // replaces defaults
      { id: "locked-down", skills: [] }, // no skills
    ],
  },
}
```

- Omit `agents.defaults.skills` for unrestricted skills by default.
- Omit `agents.list[].skills` to inherit the defaults.
- Set `agents.list[].skills: []` for no skills.
- A non-empty `agents.list[].skills` list is the final set for that agent; it
  does not merge with defaults.

### `agents.defaults.skipBootstrap`

Disables automatic creation of workspace bootstrap files (`AGENTS.md`, `SOUL.md`, `TOOLS.md`, `IDENTITY.md`, `USER.md`, `HEARTBEAT.md`, `BOOTSTRAP.md`).

```json5
{
  agents: { defaults: { skipBootstrap: true } },
}
```

### `agents.defaults.contextInjection`

Controls when workspace bootstrap files are injected into the system prompt. Default: `"always"`.

- `"continuation-skip"`: safe continuation turns (after a completed assistant response) skip workspace bootstrap re-injection, reducing prompt size. Heartbeat runs and post-compaction retries still rebuild context.

```json5
{
  agents: { defaults: { contextInjection: "continuation-skip" } },
}
```

### `agents.defaults.bootstrapMaxChars`

Max characters per workspace bootstrap file before truncation. Default: `20000`.

```json5
{
  agents: { defaults: { bootstrapMaxChars: 20000 } },
}
```

### `agents.defaults.bootstrapTotalMaxChars`

Max total characters injected across all workspace bootstrap files. Default: `150000`.

```json5
{
  agents: { defaults: { bootstrapTotalMaxChars: 150000 } },
}
```

### `agents.defaults.bootstrapPromptTruncationWarning`

Controls agent-visible warning text when bootstrap context is truncated.
Default: `"once"`.

- `"off"`: never inject warning text into the system prompt.
- `"once"`: inject warning once per unique truncation signature (recommended).
- `"always"`: inject warning on every run when truncation exists.

```json5
{
  agents: { defaults: { bootstrapPromptTruncationWarning: "once" } }, // off | once | always
}
```

### `agents.defaults.imageMaxDimensionPx`

Max pixel size for the longest image side in transcript/tool image blocks before provider calls.
Default: `1200`.

Lower values usually reduce vision-token usage and request payload size for screenshot-heavy runs.
Higher values preserve more visual detail.

```json5
{
  agents: { defaults: { imageMaxDimensionPx: 1200 } },
}
```

### `agents.defaults.userTimezone`

Timezone for system prompt context (not message timestamps). Falls back to host timezone.

```json5
{
  agents: { defaults: { userTimezone: "America/Chicago" } },
}
```

### `agents.defaults.timeFormat`

Time format in system prompt. Default: `auto` (OS preference).

```json5
{
  agents: { defaults: { timeFormat: "auto" } }, // auto | 12 | 24
}
```

### `agents.defaults.model`

```json5
{
  agents: {
    defaults: {
      models: {
        "anthropic/claude-opus-4-6": { alias: "opus" },
        "minimax/MiniMax-M2.7": { alias: "minimax" },
      },
      model: {
        primary: "anthropic/claude-opus-4-6",
        fallbacks: ["minimax/MiniMax-M2.7"],
      },
      imageModel: {
        primary: "openrouter/qwen/qwen-2.5-vl-72b-instruct:free",
        fallbacks: ["openrouter/google/gemini-2.0-flash-vision:free"],
      },
      imageGenerationModel: {
        primary: "openai/gpt-image-1",
        fallbacks: ["google/gemini-3.1-flash-image-preview"],
      },
      videoGenerationModel: {
        primary: "qwen/wan2.6-t2v",
        fallbacks: ["qwen/wan2.6-i2v"],
      },
      pdfModel: {
        primary: "anthropic/claude-opus-4-6",
        fallbacks: ["openai/gpt-5.4-mini"],
      },
      params: { cacheRetention: "long" }, // global default provider params
      pdfMaxBytesMb: 10,
      pdfMaxPages: 20,
      thinkingDefault: "low",
      verboseDefault: "off",
      elevatedDefault: "on",
      timeoutSeconds: 600,
      mediaMaxMb: 5,
      contextTokens: 200000,
      maxConcurrent: 3,
    },
  },
}
```

- `model`: accepts either a string (`"provider/model"`) or an object (`{ primary, fallbacks }`).
  - String form sets only the primary model.
  - Object form sets primary plus ordered failover models.
- `imageModel`: accepts either a string (`"provider/model"`) or an object (`{ primary, fallbacks }`).
  - Used by the `image` tool path as its vision-model config.
  - Also used as fallback routing when the selected/default model cannot accept image input.
- `imageGenerationModel`: accepts either a string (`"provider/model"`) or an object (`{ primary, fallbacks }`).
  - Used by the shared image-generation capability and any future tool/plugin surface that generates images.
  - Typical values: `google/gemini-3.1-flash-image-preview` for native Gemini image generation, `fal/fal-ai/flux/dev` for fal, or `openai/gpt-image-1` for OpenAI Images.
  - If you select a provider/model directly, configure the matching provider auth/API key too (for example `GEMINI_API_KEY` or `GOOGLE_API_KEY` for `google/*`, `OPENAI_API_KEY` for `openai/*`, `FAL_KEY` for `fal/*`).
  - If omitted, `image_generate` can still infer an auth-backed provider default. It tries the current default provider first, then the remaining registered image-generation providers in provider-id order.
- `musicGenerationModel`: accepts either a string (`"provider/model"`) or an object (`{ primary, fallbacks }`).
  - Used by the shared music-generation capability and the built-in `music_generate` tool.
  - Typical values: `google/lyria-3-clip-preview`, `google/lyria-3-pro-preview`, or `minimax/music-2.5+`.
  - If omitted, `music_generate` can still infer an auth-backed provider default. It tries the current default provider first, then the remaining registered music-generation providers in provider-id order.
  - If you select a provider/model directly, configure the matching provider auth/API key too.
- `videoGenerationModel`: accepts either a string (`"provider/model"`) or an object (`{ primary, fallbacks }`).
  - Used by the shared video-generation capability and the built-in `video_generate` tool.
  - Typical values: `qwen/wan2.6-t2v`, `qwen/wan2.6-i2v`, `qwen/wan2.6-r2v`, `qwen/wan2.6-r2v-flash`, or `qwen/wan2.7-r2v`.
  - If omitted, `video_generate` can still infer an auth-backed provider default. It tries the current default provider first, then the remaining registered video-generation providers in provider-id order.
  - If you select a provider/model directly, configure the matching provider auth/API key too.
  - The bundled Qwen video-generation provider supports up to 1 output video, 1 input image, 4 input videos, 10 seconds duration, and provider-level `size`, `aspectRatio`, `resolution`, `audio`, and `watermark` options.
- `pdfModel`: accepts either a string (`"provider/model"`) or an object (`{ primary, fallbacks }`).
  - Used by the `pdf` tool for model routing.
  - If omitted, the PDF tool falls back to `imageModel`, then to the resolved session/default model.
- `pdfMaxBytesMb`: default PDF size limit for the `pdf` tool when `maxBytesMb` is not passed at call time.
- `pdfMaxPages`: default maximum pages considered by extraction fallback mode in the `pdf` tool.
- `verboseDefault`: default verbose level for agents. Values: `"off"`, `"on"`, `"full"`. Default: `"off"`.
- `elevatedDefault`: default elevated-output level for agents. Values: `"off"`, `"on"`, `"ask"`, `"full"`. Default: `"on"`.
- `model.primary`: format `provider/model` (e.g. `openai/gpt-5.4`). If you omit the provider, KaijiBot tries an alias first, then a unique configured-provider match for that exact model id, and only then falls back to the configured default provider (deprecated compatibility behavior, so prefer explicit `provider/model`). If that provider no longer exposes the configured default model, KaijiBot falls back to the first configured provider/model instead of surfacing a stale removed-provider default.
- `models`: the configured model catalog and allowlist for `/model`. Each entry can include `alias` (shortcut) and `params` (provider-specific, for example `temperature`, `maxTokens`, `cacheRetention`, `context1m`).
- `params`: global default provider parameters applied to all models. Set at `agents.defaults.params` (e.g. `{ cacheRetention: "long" }`).
- `params` merge precedence (config): `agents.defaults.params` (global base) is overridden by `agents.defaults.models["provider/model"].params` (per-model), then `agents.list[].params` (matching agent id) overrides by key. See [Prompt Caching](/reference/prompt-caching) for details.
- Config writers that mutate these fields (for example `/models set`, `/models set-image`, and fallback add/remove commands) save canonical object form and preserve existing fallback lists when possible.
- `maxConcurrent`: max parallel agent runs across sessions (each session still serialized). Default: 4.

**Built-in alias shorthands** (only apply when the model is in `agents.defaults.models`):

| Alias               | Model                                  |

Your configured aliases always win over defaults.

Z.AI GLM-4.x models automatically enable thinking mode unless you set `--thinking off` or define `agents.defaults.models["zai/<model>"].params.thinking` yourself.
Z.AI models enable `tool_stream` by default for tool call streaming. Set `agents.defaults.models["zai/<model>"].params.tool_stream` to `false` to disable it.
Anthropic Claude 4.6 models default to `adaptive` thinking when no explicit thinking level is set.

### `agents.defaults.cliBackends`

Optional CLI backends for text-only fallback runs (no tool calls). Useful as a backup when API providers fail.

```json5
{
  agents: {
    defaults: {
      cliBackends: {
        "codex-cli": {
          command: "/opt/homebrew/bin/codex",
        },
        "my-cli": {
          command: "my-cli",
          args: ["--json"],
          output: "json",
          modelArg: "--model",
          sessionArg: "--session",
          sessionMode: "existing",
          systemPromptArg: "--system",
          systemPromptWhen: "first",
          imageArg: "--image",
          imageMode: "repeat",
        },
      },
    },
  },
}
```

- CLI backends are text-first; tools are always disabled.
- Sessions supported when `sessionArg` is set.
- Image pass-through supported when `imageArg` accepts file paths.

### `agents.defaults.systemPromptOverride`

Replace the entire KaijiBot-assembled system prompt with a fixed string. Set at the default level (`agents.defaults.systemPromptOverride`) or per agent (`agents.list[].systemPromptOverride`). Per-agent values take precedence; an empty or whitespace-only value is ignored. Useful for controlled prompt experiments.

```json5
{
  agents: {
    defaults: {
      systemPromptOverride: "You are a helpful assistant.",
    },
  },
}
```

### `agents.defaults.heartbeat`

Periodic heartbeat runs.

```json5
{
  agents: {
    defaults: {
      heartbeat: {
        every: "30m", // 0m disables
        model: "openai/gpt-5.4-mini",
        includeReasoning: false,
        includeSystemPromptSection: true, // default: true; false omits the Heartbeat section from the system prompt
        lightContext: false, // default: false; true keeps only HEARTBEAT.md from workspace bootstrap files
        isolatedSession: false, // default: false; true runs each heartbeat in a fresh session (no conversation history)
        session: "main",
        to: "+15555550123",
        directPolicy: "allow", // allow (default) | block
        target: "none", // default: none | options: last | whatsapp | telegram | discord | ...
        prompt: "Read HEARTBEAT.md if it exists...",
        ackMaxChars: 300,
        suppressToolErrorWarnings: false,
      },
    },
  },
}
```

- `every`: duration string (ms/s/m/h). Default: `30m` (API-key auth) or `1h` (OAuth auth). Set to `0m` to disable.
- `includeSystemPromptSection`: when false, omits the Heartbeat section from the system prompt and skips `HEARTBEAT.md` injection into bootstrap context. Default: `true`.
- `suppressToolErrorWarnings`: when true, suppresses tool error warning payloads during heartbeat runs.
- `directPolicy`: direct/DM delivery policy. `allow` (default) permits direct-target delivery. `block` suppresses direct-target delivery and emits `reason=dm-blocked`.
- `lightContext`: when true, heartbeat runs use lightweight bootstrap context and keep only `HEARTBEAT.md` from workspace bootstrap files.
- `isolatedSession`: when true, each heartbeat runs in a fresh session with no prior conversation history. Same isolation pattern as cron `sessionTarget: "isolated"`. Reduces per-heartbeat token cost from ~100K to ~2-5K tokens.
- Per-agent: set `agents.list[].heartbeat`. When any agent defines `heartbeat`, **only those agents** run heartbeats.
- Heartbeats run full agent turns — shorter intervals burn more tokens.

### `agents.defaults.compaction`

```json5
{
  agents: {
    defaults: {
      compaction: {
        mode: "safeguard", // default | safeguard
        provider: "my-provider", // id of a registered compaction provider plugin (optional)
        timeoutSeconds: 900,
        reserveTokensFloor: 24000,
        identifierPolicy: "strict", // strict | off | custom
        identifierInstructions: "Preserve deployment IDs, ticket IDs, and host:port pairs exactly.", // used when identifierPolicy=custom
        postCompactionSections: ["Session Startup", "Red Lines"], // [] disables reinjection
        model: "openrouter/anthropic/claude-sonnet-4-6", // optional compaction-only model override
        notifyUser: true, // send a brief notice when compaction starts (default: false)
        memoryFlush: {
          enabled: true,
          softThresholdTokens: 6000,
          systemPrompt: "Session nearing compaction. Store durable memories now.",
          prompt: "Write any lasting notes to memory/YYYY-MM-DD.md; reply with the exact silent token NO_REPLY if nothing to store.",
        },
      },
    },
  },
}
```

- `mode`: `default` or `safeguard` (chunked summarization for long histories). See [Compaction](/concepts/compaction).
- `provider`: id of a registered compaction provider plugin. When set, the provider's `summarize()` is called instead of built-in LLM summarization. Falls back to built-in on failure. Setting a provider forces `mode: "safeguard"`. See [Compaction](/concepts/compaction).
- `timeoutSeconds`: maximum seconds allowed for a single compaction operation before KaijiBot aborts it. Default: `900`.
- `identifierPolicy`: `strict` (default), `off`, or `custom`. `strict` prepends built-in opaque identifier retention guidance during compaction summarization.
- `identifierInstructions`: optional custom identifier-preservation text used when `identifierPolicy=custom`.
- `postCompactionSections`: optional AGENTS.md H2/H3 section names to re-inject after compaction. Defaults to `["Session Startup", "Red Lines"]`; set `[]` to disable reinjection. When unset or explicitly set to that default pair, older `Every Session`/`Safety` headings are also accepted as a legacy fallback.
- `model`: optional `provider/model-id` override for compaction summarization only. Use this when the main session should keep one model but compaction summaries should run on another; when unset, compaction uses the session's primary model.
- `notifyUser`: when `true`, sends a brief notice to the user when compaction starts (for example, "Compacting context..."). Disabled by default to keep compaction silent.
- `memoryFlush`: silent agentic turn before auto-compaction to store durable memories. Skipped when workspace is read-only.

### `agents.defaults.contextPruning`

Prunes **old tool results** from in-memory context before sending to the LLM. Does **not** modify session history on disk.

```json5
{
  agents: {
    defaults: {
      contextPruning: {
        mode: "cache-ttl", // off | cache-ttl
        ttl: "1h", // duration (ms/s/m/h), default unit: minutes
        keepLastAssistants: 3,
        softTrimRatio: 0.3,
        hardClearRatio: 0.5,
        minPrunableToolChars: 50000,
        softTrim: { maxChars: 4000, headChars: 1500, tailChars: 1500 },
        hardClear: { enabled: true, placeholder: "[Old tool result content cleared]" },
        tools: { deny: ["browser", "canvas"] },
      },
    },
  },
}
```

<Accordion title="cache-ttl mode behavior">

- `mode: "cache-ttl"` enables pruning passes.
- `ttl` controls how often pruning can run again (after the last cache touch).
- Pruning soft-trims oversized tool results first, then hard-clears older tool results if needed.

**Soft-trim** keeps beginning + end and inserts `...` in the middle.

**Hard-clear** replaces the entire tool result with the placeholder.

Notes:

- Image blocks are never trimmed/cleared.
- Ratios are character-based (approximate), not exact token counts.
- If fewer than `keepLastAssistants` assistant messages exist, pruning is skipped.

</Accordion>

See [Session Pruning](/concepts/session-pruning) for behavior details.

### Block streaming

```json5
{
  agents: {
    defaults: {
      blockStreamingDefault: "off", // on | off
      blockStreamingBreak: "text_end", // text_end | message_end
      blockStreamingChunk: { minChars: 800, maxChars: 1200 },
      blockStreamingCoalesce: { idleMs: 1000 },
      humanDelay: { mode: "natural" }, // off | natural | custom (use minMs/maxMs)
    },
  },
}
```

- Non-Telegram channels require explicit `*.blockStreaming: true` to enable block replies.
- Channel overrides: `channels.<channel>.blockStreamingCoalesce` (and per-account variants). Signal/Slack/Discord/Google Chat default `minChars: 1500`.
- `humanDelay`: randomized pause between block replies. `natural` = 800–2500ms. Per-agent override: `agents.list[].humanDelay`.

See [Streaming](/concepts/streaming) for behavior + chunking details.

### Typing indicators

```json5
{
  agents: {
    defaults: {
      typingMode: "instant", // never | instant | thinking | message
      typingIntervalSeconds: 6,
    },
  },
}
```

- Defaults: `instant` for direct chats/mentions, `message` for unmentioned group chats.
- Per-session overrides: `session.typingMode`, `session.typingIntervalSeconds`.

See [Typing Indicators](/concepts/typing-indicators).

### `agents.defaults.sandbox`

Optional sandboxing for the embedded agent. See [Sandboxing](/gateway/sandboxing) for the full guide.

```json5
{
  agents: {
    defaults: {
      sandbox: {
        mode: "non-main", // off | non-main | all

<Accordion title="Sandbox details">

**Backend:**

- `docker`: local Docker runtime (default)
- `ssh`: generic SSH-backed remote runtime
- `openshell`: OpenShell runtime

When `backend: "openshell"` is selected, runtime-specific settings move to
`plugins.entries.openshell.config`.

**SSH backend config:**

- `target`: SSH target in `user@host[:port]` form
- `command`: SSH client command (default: `ssh`)
- `workspaceRoot`: absolute remote root used for per-scope workspaces
- `identityFile` / `certificateFile` / `knownHostsFile`: existing local files passed to OpenSSH
- `identityData` / `certificateData` / `knownHostsData`: inline contents or SecretRefs that KaijiBot materializes into temp files at runtime
- `strictHostKeyChecking` / `updateHostKeys`: OpenSSH host-key policy knobs

**SSH auth precedence:**

- `identityData` wins over `identityFile`
- `certificateData` wins over `certificateFile`
- `knownHostsData` wins over `knownHostsFile`
- SecretRef-backed `*Data` values are resolved from the active secrets runtime snapshot before the sandbox session starts

**SSH backend behavior:**

- seeds the remote workspace once after create or recreate
- then keeps the remote SSH workspace canonical
- routes `exec`, file tools, and media paths over SSH
- does not sync remote changes back to the host automatically
- does not support sandbox browser containers

**Workspace access:**

- `none`: per-scope sandbox workspace under `~/.kaijibot/sandboxes`
- `ro`: sandbox workspace at `/workspace`, agent workspace mounted read-only at `/agent`
- `rw`: agent workspace mounted read/write at `/workspace`

**Scope:**

- `session`: per-session container + workspace
- `agent`: one container + workspace per agent (default)
- `shared`: shared container and workspace (no cross-session isolation)

**OpenShell plugin config:**

```json5
{
  plugins: {
    entries: {
      openshell: {
        enabled: true,
        config: {
          mode: "mirror", // mirror | remote
          from: "kaijibot",
          remoteWorkspaceDir: "/sandbox",
          remoteAgentWorkspaceDir: "/agent",
          gateway: "lab", // optional
          gatewayEndpoint: "https://lab.example", // optional
          policy: "strict", // optional OpenShell policy id
          providers: ["openai"], // optional
          autoProviders: true,
          timeoutSeconds: 120,
        },
      },
    },
  },
}
```

**OpenShell mode:**

- `mirror`: seed remote from local before exec, sync back after exec; local workspace stays canonical
- `remote`: seed remote once when the sandbox is created, then keep the remote workspace canonical

In `remote` mode, host-local edits made outside KaijiBot are not synced into the sandbox automatically after the seed step.
Transport is SSH into the OpenShell sandbox, but the plugin owns sandbox lifecycle and optional mirror sync.

**`setupCommand`** runs once after container creation (via `sh -lc`). Needs network egress, writable root, root user.

**Containers default to `network: "none"`** — set to `"bridge"` (or a custom bridge network) if the agent needs outbound access.
`"host"` is blocked. `"container:<id>"` is blocked by default unless you explicitly set
`sandbox.docker.dangerouslyAllowContainerNamespaceJoin: true` (break-glass).

**Inbound attachments** are staged into `media/inbound/*` in the active workspace.

**`docker.binds`** mounts additional host directories; global and per-agent binds are merged.

**Sandboxed browser** (`sandbox.browser.enabled`): Chromium + CDP in a container. noVNC URL injected into system prompt. Does not require `browser.enabled` in `kaijibot.json`.
noVNC observer access uses VNC auth by default and KaijiBot emits a short-lived token URL (instead of exposing the password in the shared URL).

- `allowHostControl: false` (default) blocks sandboxed sessions from targeting the host browser.
- `network` defaults to `kaijibot-sandbox-browser` (dedicated bridge network). Set to `bridge` only when you explicitly want global bridge connectivity.
- `cdpSourceRange` optionally restricts CDP ingress at the container edge to a CIDR range (for example `172.21.0.1/32`).
- `sandbox.browser.binds` mounts additional host directories into the sandbox browser container only. When set (including `[]`), it replaces `docker.binds` for the browser container.
- Launch defaults are defined in `scripts/sandbox-browser-entrypoint.sh` and tuned for container hosts:
  - `--remote-debugging-address=127.0.0.1`
  - `--remote-debugging-port=<derived from KAIJIBOT_BROWSER_CDP_PORT>`
  - `--user-data-dir=${HOME}/.chrome`
  - `--no-first-run`
  - `--no-default-browser-check`
  - `--disable-3d-apis`
  - `--disable-gpu`
  - `--disable-software-rasterizer`
  - `--disable-dev-shm-usage`
  - `--disable-background-networking`
  - `--disable-features=TranslateUI`
  - `--disable-breakpad`
  - `--disable-crash-reporter`
  - `--renderer-process-limit=2`
  - `--no-zygote`
  - `--metrics-recording-only`
  - `--disable-extensions` (default enabled)
  - `--disable-3d-apis`, `--disable-software-rasterizer`, and `--disable-gpu` are
    enabled by default and can be disabled with
    `KAIJIBOT_BROWSER_DISABLE_GRAPHICS_FLAGS=0` if WebGL/3D usage requires it.
  - `KAIJIBOT_BROWSER_DISABLE_EXTENSIONS=0` re-enables extensions if your workflow
    depends on them.
  - `--renderer-process-limit=2` can be changed with
    `KAIJIBOT_BROWSER_RENDERER_PROCESS_LIMIT=<N>`; set `0` to use Chromium's
    default process limit.
  - plus `--no-sandbox` and `--disable-setuid-sandbox` when `noSandbox` is enabled.
  - Defaults are the container image baseline; use a custom browser image with a custom
    entrypoint to change container defaults.

</Accordion>

Browser sandboxing and `sandbox.docker.binds` are Docker-only.

Build images:

```bash
scripts/sandbox-setup.sh           # main sandbox image
scripts/sandbox-browser-setup.sh   # optional browser image
```

### `agents.list` (per-agent overrides)

```json5
{
  agents: {
    list: [
      {
        id: "main",
        default: true,
        name: "Main Agent",
        workspace: "~/.kaijibot/workspace",
        agentDir: "~/.kaijibot/agents/main/agent",
        model: "anthropic/claude-opus-4-6", // or { primary, fallbacks }
        thinkingDefault: "high", // per-agent thinking level override
        reasoningDefault: "on", // per-agent reasoning visibility override
        fastModeDefault: false, // per-agent fast mode override
        params: { cacheRetention: "none" }, // overrides matching defaults.models params by key
        skills: ["docs-search"], // replaces agents.defaults.skills when set
        identity: {
          name: "Samantha",
          theme: "helpful sloth",
          emoji: "🦥",
          avatar: "avatars/samantha.png",
        },
        groupChat: { mentionPatterns: ["@kaijibot"] },
        sandbox: { mode: "off" },
        runtime: {
          type: "acp",
          acp: {
            agent: "codex",
            backend: "acpx",
            mode: "persistent",
            cwd: "/workspace/kaijibot",
          },
        },
        subagents: { allowAgents: ["*"] },
        tools: {
          profile: "coding",
          allow: ["browser"],
          deny: ["canvas"],
          elevated: { enabled: true },
        },
      },
    ],
  },
}
```

- `id`: stable agent id (required).
- `default`: when multiple are set, first wins (warning logged). If none set, first list entry is default.
- `model`: string form overrides `primary` only; object form `{ primary, fallbacks }` overrides both (`[]` disables global fallbacks). Cron jobs that only override `primary` still inherit default fallbacks unless you set `fallbacks: []`.
- `params`: per-agent stream params merged over the selected model entry in `agents.defaults.models`. Use this for agent-specific overrides like `cacheRetention`, `temperature`, or `maxTokens` without duplicating the whole model catalog.
- `skills`: optional per-agent skill allowlist. If omitted, the agent inherits `agents.defaults.skills` when set; an explicit list replaces defaults instead of merging, and `[]` means no skills.
- `thinkingDefault`: optional per-agent default thinking level (`off | minimal | low | medium | high | xhigh | adaptive`). Overrides `agents.defaults.thinkingDefault` for this agent when no per-message or session override is set.
- `reasoningDefault`: optional per-agent default reasoning visibility (`on | off | stream`). Applies when no per-message or session reasoning override is set.
- `fastModeDefault`: optional per-agent default for fast mode (`true | false`). Applies when no per-message or session fast-mode override is set.
- `runtime`: optional per-agent runtime descriptor. Use `type: "acp"` with `runtime.acp` defaults (`agent`, `backend`, `mode`, `cwd`) when the agent should default to ACP harness sessions.
- `identity.avatar`: workspace-relative path, `http(s)` URL, or `data:` URI.
- `identity` derives defaults: `ackReaction` from `emoji`, `mentionPatterns` from `name`/`emoji`.
- `subagents.allowAgents`: allowlist of agent ids for `sessions_spawn` (`["*"]` = any; default: same agent only).
- Sandbox inheritance guard: if the requester session is sandboxed, `sessions_spawn` rejects targets that would run unsandboxed.
- `subagents.requireAgentId`: when true, block `sessions_spawn` calls that omit `agentId` (forces explicit profile selection; default: false).

## Multi-agent routing

Run multiple isolated agents inside one Gateway. See [Multi-Agent](/concepts/multi-agent).

```json5
{
  agents: {
    list: [
      { id: "home", default: true, workspace: "~/.kaijibot/workspace-home" },
      { id: "work", workspace: "~/.kaijibot/workspace-work" },
    ],
  },
  bindings: [
    { agentId: "home", match: { channel: "whatsapp", accountId: "personal" } },
    { agentId: "work", match: { channel: "whatsapp", accountId: "biz" } },
  ],
}
```

### Binding match fields

- `type` (optional): `route` for normal routing (missing type defaults to route), `acp` for persistent ACP conversation bindings.
- `match.channel` (required)
- `match.accountId` (optional; `*` = any account; omitted = default account)
- `match.peer` (optional; `{ kind: direct|group|channel, id }`)
- `match.guildId` / `match.teamId` (optional; channel-specific)
- `acp` (optional; only for `type: "acp"`): `{ mode, label, cwd, backend }`

**Deterministic match order:**

1. `match.peer`
2. `match.guildId`
3. `match.teamId`
4. `match.accountId` (exact, no peer/guild/team)
5. `match.accountId: "*"` (channel-wide)
6. Default agent

Within each tier, the first matching `bindings` entry wins.

For `type: "acp"` entries, KaijiBot resolves by exact conversation identity (`match.channel` + account + `match.peer.id`) and does not use the route binding tier order above.

}
```

<Accordion title="Session field details">

- **`scope`**: base session grouping strategy for group-chat contexts.
  - `per-sender` (default): each sender gets an isolated session within a channel context.
  - `global`: all participants in a channel context share a single session (use only when shared context is intended).
- **`dmScope`**: how DMs are grouped.
  - `main`: all DMs share the main session.
  - `per-peer`: isolate by sender id across channels.
  - `per-channel-peer`: isolate per channel + sender (recommended for multi-user inboxes).
  - `per-account-channel-peer`: isolate per account + channel + sender (recommended for multi-account).
- **`identityLinks`**: map canonical ids to provider-prefixed peers for cross-channel session sharing.
- **`reset`**: primary reset policy. `daily` resets at `atHour` local time; `idle` resets after `idleMinutes`. When both configured, whichever expires first wins.
- **`resetByType`**: per-type overrides (`direct`, `group`, `thread`). Legacy `dm` accepted as alias for `direct`.
- **`parentForkMaxTokens`**: max parent-session `totalTokens` allowed when creating a forked thread session (default `100000`).
  - If parent `totalTokens` is above this value, KaijiBot starts a fresh thread session instead of inheriting parent transcript history.
  - Set `0` to disable this guard and always allow parent forking.
- **`mainKey`**: legacy field. Runtime always uses `"main"` for the main direct-chat bucket.
- **`agentToAgent.maxPingPongTurns`**: maximum reply-back turns between agents during agent-to-agent exchanges (integer, range: `0`–`5`). `0` disables ping-pong chaining.
- **`sendPolicy`**: match by `channel`, `chatType` (`direct|group|channel`, with legacy `dm` alias), `keyPrefix`, or `rawKeyPrefix`. First deny wins.
- **`maintenance`**: session-store cleanup + retention controls.
  - `mode`: `warn` emits warnings only; `enforce` applies cleanup.
  - `pruneAfter`: age cutoff for stale entries (default `30d`).
  - `maxEntries`: maximum number of entries in `sessions.json` (default `500`).
  - `rotateBytes`: rotate `sessions.json` when it exceeds this size (default `10mb`).
  - `resetArchiveRetention`: retention for `*.reset.<timestamp>` transcript archives. Defaults to `pruneAfter`; set `false` to disable.
  - `maxDiskBytes`: optional sessions-directory disk budget. In `warn` mode it logs warnings; in `enforce` mode it removes oldest artifacts/sessions first.
  - `highWaterBytes`: optional target after budget cleanup. Defaults to `80%` of `maxDiskBytes`.
- **`threadBindings`**: global defaults for thread-bound session features.
  - `enabled`: master default switch (providers can override; Discord uses `channels.discord.threadBindings.enabled`)
  - `idleHours`: default inactivity auto-unfocus in hours (`0` disables; providers can override)
  - `maxAgeHours`: default hard max age in hours (`0` disables; providers can override)

## Messages

```json5
{
  messages: {
    responsePrefix: "🦞", // or "auto"
    ackReaction: "👀",
    ackReactionScope: "group-mentions", // group-mentions | group-all | direct | all
    removeAckAfterReply: false,
    queue: {
      mode: "collect", // steer | followup | collect | steer-backlog | steer+backlog | queue | interrupt
      debounceMs: 1000,
      cap: 20,
      drop: "summarize", // old | new | summarize
      byChannel: {
        whatsapp: "collect",
        telegram: "collect",
      },
    },
    inbound: {
      debounceMs: 2000, // 0 disables
      byChannel: {
        whatsapp: 5000,
        slack: 1500,
      },
    },
  },
}
```

### Response prefix

Per-channel/account overrides: `channels.<channel>.responsePrefix`, `channels.<channel>.accounts.<id>.responsePrefix`.

Resolution (most specific wins): account → channel → global. `""` disables and stops cascade. `"auto"` derives `[{identity.name}]`.

**Template variables:**

| Variable          | Description            | Example                     |
| ----------------- | ---------------------- | --------------------------- |
| `{model}`         | Short model name       | `claude-opus-4-6`           |
| `{modelFull}`     | Full model identifier  | `anthropic/claude-opus-4-6` |
| `{provider}`      | Provider name          | `anthropic`                 |
| `{thinkingLevel}` | Current thinking level | `high`, `low`, `off`        |
| `{identity.name}` | Agent identity name    | (same as `"auto"`)          |

Variables are case-insensitive. `{think}` is an alias for `{thinkingLevel}`.

### Ack reaction

- Defaults to active agent's `identity.emoji`, otherwise `"👀"`. Set `""` to disable.
- Per-channel overrides: `channels.<channel>.ackReaction`, `channels.<channel>.accounts.<id>.ackReaction`.
- Resolution order: account → channel → `messages.ackReaction` → identity fallback.
- Scope: `group-mentions` (default), `group-all`, `direct`, `all`.
- `removeAckAfterReply`: removes ack after reply on Slack, Discord, and Telegram.
- `messages.statusReactions.enabled`: enables lifecycle status reactions on Slack, Discord, and Telegram.
  On Slack and Discord, unset keeps status reactions enabled when ack reactions are active.
  On Telegram, set it explicitly to `true` to enable lifecycle status reactions.

### Inbound debounce

Batches rapid text-only messages from the same sender into a single agent turn. Media/attachments flush immediately. Control commands bypass debouncing.

### TTS (text-to-speech)

```json5
{
  messages: {
    tts: {
      auto: "always", // off | always | inbound | tagged
      mode: "final", // final | all
      provider: "elevenlabs",
      summaryModel: "openai/gpt-4.1-mini",
      modelOverrides: { enabled: true },
      maxTextLength: 4000,
      timeoutMs: 30000,
      prefsPath: "~/.kaijibot/settings/tts.json",
      elevenlabs: {
        apiKey: "elevenlabs_api_key",
        baseUrl: "https://api.elevenlabs.io",
        voiceId: "voice_id",
        modelId: "eleven_multilingual_v2",
        seed: 42,
        applyTextNormalization: "auto",
        languageCode: "en",
        voiceSettings: {
          stability: 0.5,
          similarityBoost: 0.75,
          style: 0.0,
          useSpeakerBoost: true,
          speed: 1.0,
        },
      },
      openai: {
        apiKey: "openai_api_key",
        baseUrl: "https://api.openai.com/v1",
        model: "gpt-4o-mini-tts",
        voice: "alloy",
      },
    },
  },
}
```

- `auto` controls the default auto-TTS mode: `off`, `always`, `inbound`, or `tagged`. `/tts on|off` can override local prefs, and `/tts status` shows the effective state.
- `summaryModel` overrides `agents.defaults.model.primary` for auto-summary.
- `modelOverrides` is enabled by default; `modelOverrides.allowProvider` defaults to `false` (opt-in).
- API keys fall back to `ELEVENLABS_API_KEY`/`XI_API_KEY` and `OPENAI_API_KEY`.
- `openai.baseUrl` overrides the OpenAI TTS endpoint. Resolution order is config, then `OPENAI_TTS_BASE_URL`, then `https://api.openai.com/v1`.
- When `openai.baseUrl` points to a non-OpenAI endpoint, KaijiBot treats it as an OpenAI-compatible TTS server and relaxes model/voice validation.

---

## Talk

Defaults for Talk mode (macOS/iOS/Android).

```json5
{
  talk: {
    provider: "elevenlabs",
    providers: {
      elevenlabs: {
        voiceId: "elevenlabs_voice_id",
        voiceAliases: {
          Clawd: "EXAVITQu4vr4xnSDxMaL",
          Roger: "CwhRBWXzGAHq8TQ4Fs17",
        },
        modelId: "eleven_v3",
        outputFormat: "mp3_44100_128",
        apiKey: "elevenlabs_api_key",
      },
    },
    silenceTimeoutMs: 1500,
    interruptOnSpeech: true,
  },
}
```

- `talk.provider` must match a key in `talk.providers` when multiple Talk providers are configured.
- Legacy flat Talk keys (`talk.voiceId`, `talk.voiceAliases`, `talk.modelId`, `talk.outputFormat`, `talk.apiKey`) are compatibility-only and are auto-migrated into `talk.providers.<provider>`.
- Voice IDs fall back to `ELEVENLABS_VOICE_ID` or `SAG_VOICE_ID`.
- `providers.*.apiKey` accepts plaintext strings or SecretRef objects.
- `ELEVENLABS_API_KEY` fallback applies only when no Talk API key is configured.
- `providers.*.voiceAliases` lets Talk directives use friendly names.
- `silenceTimeoutMs` controls how long Talk mode waits after user silence before it sends the transcript. Unset keeps the platform default pause window (`700 ms on macOS and Android, 900 ms on iOS`).

## Tools

### Tool profiles

`tools.profile` sets a base allowlist before `tools.allow`/`tools.deny`:

Local onboarding defaults new local configs to `tools.profile: "coding"` when unset (existing explicit profiles are preserved).

| Profile     | Includes                                                                                                                        |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------- |
| `minimal`   | `session_status` only                                                                                                           |
| `coding`    | `group:fs`, `group:runtime`, `group:web`, `group:sessions`, `group:memory`, `cron`, `image`, `image_generate`, `video_generate` |
| `messaging` | `group:messaging`, `sessions_list`, `sessions_history`, `sessions_send`, `session_status`                                       |
| `full`      | No restriction (same as unset)                                                                                                  |

### Tool groups

| Group              | Tools                                                                                                                   |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------- |
| `group:runtime`    | `exec`, `process`, `code_execution` (`bash` is accepted as an alias for `exec`)                                         |
| `group:fs`         | `read`, `write`, `edit`, `apply_patch`                                                                                  |
| `group:sessions`   | `sessions_list`, `sessions_history`, `sessions_send`, `sessions_spawn`, `sessions_yield`, `subagents`, `session_status` |
| `group:memory`     | `memory_search`, `memory_get`                                                                                           |
| `group:web`        | `web_search`, `x_search`, `web_fetch`                                                                                   |
| `group:ui`         | `browser`, `canvas`                                                                                                     |
| `group:automation` | `cron`, `gateway`                                                                                                       |
| `group:messaging`  | `message`                                                                                                               |
| `group:nodes`      | `nodes`                                                                                                                 |
| `group:agents`     | `agents_list`                                                                                                           |
| `group:media`      | `image`, `image_generate`, `video_generate`, `tts`                                                                      |
| `group:kaijibot`   | All built-in tools (excludes provider plugins)                                                                          |

### `tools.allow` / `tools.deny`

Global tool allow/deny policy (deny wins). Case-insensitive, supports `*` wildcards. Applied even when Docker sandbox is off.

```json5
{
  tools: { deny: ["browser", "canvas"] },
}
```

### `tools.byProvider`

Further restrict tools for specific providers or models. Order: base profile → provider profile → allow/deny.

```json5
{
  tools: {
    profile: "coding",
    byProvider: {
      "google-antigravity": { profile: "minimal" },
      "openai/gpt-5.4": { allow: ["group:fs", "sessions_list"] },
    },
  },
}
```

### `tools.elevated`

Controls elevated exec access outside the sandbox:

```json5
{
  tools: {
    elevated: {
      enabled: true,
      allowFrom: {
        whatsapp: ["+15555550123"],
        discord: ["1234567890123", "987654321098765432"],
      },
    },
  },
}
```

- Per-agent override (`agents.list[].tools.elevated`) can only further restrict.
- `/elevated on|off|ask|full` stores state per session; inline directives apply to single message.
- Elevated `exec` bypasses sandboxing and uses the configured escape path (`gateway` by default, or `node` when the exec target is `node`).

### `tools.exec`

```json5
{
  tools: {
    exec: {
      backgroundMs: 10000,
      timeoutSec: 1800,
      cleanupMs: 1800000,
      notifyOnExit: true,
      notifyOnExitEmptySuccess: false,
      applyPatch: {
        enabled: false,
        allowModels: ["gpt-5.4"],
      },
    },
  },
}
```

### `tools.loopDetection`

Tool-loop safety checks are **disabled by default**. Set `enabled: true` to activate detection.
Settings can be defined globally in `tools.loopDetection` and overridden per-agent at `agents.list[].tools.loopDetection`.

```json5
{
  tools: {
    loopDetection: {
      enabled: true,
      historySize: 30,
      warningThreshold: 10,
      criticalThreshold: 20,
      globalCircuitBreakerThreshold: 30,
      detectors: {
        genericRepeat: true,
        knownPollNoProgress: true,
        pingPong: true,
      },
    },
  },
}
```

- `historySize`: max tool-call history retained for loop analysis.
- `warningThreshold`: repeating no-progress pattern threshold for warnings.
- `criticalThreshold`: higher repeating threshold for blocking critical loops.
- `globalCircuitBreakerThreshold`: hard stop threshold for any no-progress run.
- `detectors.genericRepeat`: warn on repeated same-tool/same-args calls.
- `detectors.knownPollNoProgress`: warn/block on known poll tools (`process.poll`, `command_status`, etc.).
- `detectors.pingPong`: warn/block on alternating no-progress pair patterns.
- If `warningThreshold >= criticalThreshold` or `criticalThreshold >= globalCircuitBreakerThreshold`, validation fails.

### `tools.web`

```json5
{
  tools: {
    web: {
      search: {

### `tools.media`

Configures inbound media understanding (image/audio/video):

```json5
{
  tools: {
    media: {
      concurrency: 2,
      asyncCompletion: {
        directSend: false, // opt-in: send finished async music/video directly to the channel
      },
      audio: {
        enabled: true,
        maxBytes: 20971520,
        scope: {
          default: "deny",
          rules: [{ action: "allow", match: { chatType: "direct" } }],
        },
        models: [
          { provider: "openai", model: "gpt-4o-mini-transcribe" },
          { type: "cli", command: "whisper", args: ["--model", "base", "{{MediaPath}}"] },
        ],
      },
      video: {
        enabled: true,
        maxBytes: 52428800,
        models: [{ provider: "google", model: "gemini-3-flash-preview" }],
      },
    },
  },
}
```

<Accordion title="Media model entry fields">

**Provider entry** (`type: "provider"` or omitted):

- `provider`: API provider id (`openai`, `anthropic`, `google`/`gemini`, `groq`, etc.)
- `model`: model id override
- `profile` / `preferredProfile`: `auth-profiles.json` profile selection

**CLI entry** (`type: "cli"`):

- `command`: executable to run
- `args`: templated args (supports `{{MediaPath}}`, `{{Prompt}}`, `{{MaxChars}}`, etc.)

**Common fields:**

- `capabilities`: optional list (`image`, `audio`, `video`). Defaults: `openai`/`anthropic`/`minimax` → image, `google` → image+audio+video, `groq` → audio.
- `prompt`, `maxChars`, `maxBytes`, `timeoutSeconds`, `language`: per-entry overrides.
- Failures fall back to the next entry.

Provider auth follows standard order: `auth-profiles.json` → env vars → `models.providers.*.apiKey`.

**Async completion fields:**

- `asyncCompletion.directSend`: when `true`, completed async `music_generate`
  and `video_generate` tasks try direct channel delivery first. Default: `false`
  (legacy requester-session wake/model-delivery path).

</Accordion>

### `tools.agentToAgent`

```json5
{
  tools: {
    agentToAgent: {
      enabled: false,
      allow: ["home", "work"],
    },
  },
}
```

### `tools.sessions`

Controls which sessions can be targeted by the session tools (`sessions_list`, `sessions_history`, `sessions_send`).

Default: `tree` (current session + sessions spawned by it, such as subagents).

```json5
{
  tools: {
    sessions: {
      // "self" | "tree" | "agent" | "all"
      visibility: "tree",
    },
  },
}
```

Notes:

- `self`: only the current session key.
- `tree`: current session + sessions spawned by the current session (subagents).
- `agent`: any session belonging to the current agent id (can include other users if you run per-sender sessions under the same agent id).
- `all`: any session. Cross-agent targeting still requires `tools.agentToAgent`.
- Sandbox clamp: when the current session is sandboxed and `agents.defaults.sandbox.sessionToolsVisibility="spawned"`, visibility is forced to `tree` even if `tools.sessions.visibility="all"`.

### `tools.sessions_spawn`

Controls inline attachment support for `sessions_spawn`.

```json5
{
  tools: {
    sessions_spawn: {
      attachments: {
        enabled: false, // opt-in: set true to allow inline file attachments
        maxTotalBytes: 5242880, // 5 MB total across all files
        maxFiles: 50,
        maxFileBytes: 1048576, // 1 MB per file
        retainOnSessionKeep: false, // keep attachments when cleanup="keep"
      },
    },
  },
}
```

Notes:

- Attachments are only supported for `runtime: "subagent"`. ACP runtime rejects them.
- Files are materialized into the child workspace at `.kaijibot/attachments/<uuid>/` with a `.manifest.json`.
- Attachment content is automatically redacted from transcript persistence.
- Base64 inputs are validated with strict alphabet/padding checks and a pre-decode size guard.
- File permissions are `0700` for directories and `0600` for files.
- Cleanup follows the `cleanup` policy: `delete` always removes attachments; `keep` retains them only when `retainOnSessionKeep: true`.

### `tools.experimental`

Experimental built-in tool flags. Default off unless a runtime-specific auto-enable rule applies.

```json5
{
  tools: {
    experimental: {
      planTool: true, // enable experimental update_plan
    },
  },
}
```

Notes:

- `planTool`: enables the structured `update_plan` tool for non-trivial multi-step work tracking.
- Default: `false` for non-OpenAI providers. OpenAI and OpenAI Codex runs auto-enable it when unset; set `false` to disable that auto-enable.
- When enabled, the system prompt also adds usage guidance so the model only uses it for substantial work and keeps at most one step `in_progress`.

### `agents.defaults.subagents`

```json5
{
  agents: {
    defaults: {
      subagents: {
        allowAgents: ["research"],
        model: "minimax/MiniMax-M2.7",
        maxConcurrent: 8,
        runTimeoutSeconds: 900,
        archiveAfterMinutes: 60,
      },
    },
  },
}
```

- `model`: default model for spawned sub-agents. If omitted, sub-agents inherit the caller's model.
- `allowAgents`: default allowlist of target agent ids for `sessions_spawn` when the requester agent does not set its own `subagents.allowAgents` (`["*"]` = any; default: same agent only).
- `runTimeoutSeconds`: default timeout (seconds) for `sessions_spawn` when the tool call omits `runTimeoutSeconds`. `0` means no timeout.
- Per-subagent tool policy: `tools.subagents.tools.allow` / `tools.subagents.tools.deny`.

---

## Custom providers and base URLs

KaijiBot uses the built-in model catalog. Add custom providers via `models.providers` in config or `~/.kaijibot/agents/<agentId>/agent/models.json`.

```json5
{
  models: {
    mode: "merge", // merge (default) | replace
    providers: {
      "custom-proxy": {
        baseUrl: "http://localhost:4000/v1",
        apiKey: "LITELLM_KEY",
        api: "openai-completions", // openai-completions | openai-responses | anthropic-messages | google-generative-ai
        models: [
          {
            id: "llama-3.1-8b",
            name: "Llama 3.1 8B",
            reasoning: false,
            input: ["text"],
            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
            contextWindow: 128000,
            contextTokens: 96000,
            maxTokens: 32000,
          },
        ],
      },
    },
  },
}
```

- Use `authHeader: true` + `headers` for custom auth needs.
- Override agent config root with `KAIJIBOT_AGENT_DIR` (or `PI_CODING_AGENT_DIR`, a legacy environment variable alias).
- Merge precedence for matching provider IDs:
  - Non-empty agent `models.json` `baseUrl` values win.
  - Non-empty agent `apiKey` values win only when that provider is not SecretRef-managed in current config/auth-profile context.
  - SecretRef-managed provider `apiKey` values are refreshed from source markers (`ENV_VAR_NAME` for env refs, `secretref-managed` for file/exec refs) instead of persisting resolved secrets.
  - SecretRef-managed provider header values are refreshed from source markers (`secretref-env:ENV_VAR_NAME` for env refs, `secretref-managed` for file/exec refs).
  - Empty or missing agent `apiKey`/`baseUrl` fall back to `models.providers` in config.
  - Matching model `contextWindow`/`maxTokens` use the higher value between explicit config and implicit catalog values.
  - Matching model `contextTokens` preserves an explicit runtime cap when present; use it to limit effective context without changing native model metadata.
  - Use `models.mode: "replace"` when you want config to fully rewrite `models.json`.
  - Marker persistence is source-authoritative: markers are written from the active source config snapshot (pre-resolution), not from resolved runtime secret values.

### Provider field details

- `models.mode`: provider catalog behavior (`merge` or `replace`).
- `models.providers`: custom provider map keyed by provider id.
- `models.providers.*.api`: request adapter (`openai-completions`, `openai-responses`, `anthropic-messages`, `google-generative-ai`, etc).
- `models.providers.*.apiKey`: provider credential (prefer SecretRef/env substitution).
- `models.providers.*.auth`: auth strategy (`api-key`, `token`, `oauth`, `aws-sdk`).
- `models.providers.*.injectNumCtxForOpenAICompat`: for Ollama + `openai-completions`, inject `options.num_ctx` into requests (default: `true`).
- `models.providers.*.authHeader`: force credential transport in the `Authorization` header when required.
- `models.providers.*.baseUrl`: upstream API base URL.
- `models.providers.*.headers`: extra static headers for proxy/tenant routing.
- `models.providers.*.request`: transport overrides for model-provider HTTP requests.
  - `request.headers`: extra headers (merged with provider defaults). Values accept SecretRef.
  - `request.auth`: auth strategy override. Modes: `"provider-default"` (use provider's built-in auth), `"authorization-bearer"` (with `token`), `"header"` (with `headerName`, `value`, optional `prefix`).
  - `request.proxy`: HTTP proxy override. Modes: `"env-proxy"` (use `HTTP_PROXY`/`HTTPS_PROXY` env vars), `"explicit-proxy"` (with `url`). Both modes accept an optional `tls` sub-object.
  - `request.tls`: TLS override for direct connections. Fields: `ca`, `cert`, `key`, `passphrase` (all accept SecretRef), `serverName`, `insecureSkipVerify`.
- `models.providers.*.models`: explicit provider model catalog entries.
- `models.providers.*.models.*.contextWindow`: native model context window metadata.
- `models.providers.*.models.*.contextTokens`: optional runtime context cap. Use this when you want a smaller effective context budget than the model's native `contextWindow`.
- `models.providers.*.models.*.compat.supportsDeveloperRole`: optional compatibility hint. For `api: "openai-completions"` with a non-empty non-native `baseUrl` (host not `api.openai.com`), KaijiBot forces this to `false` at runtime. Empty/omitted `baseUrl` keeps default OpenAI behavior.
- `models.providers.*.models.*.compat.requiresStringContent`: optional compatibility hint for string-only OpenAI-compatible chat endpoints. When `true`, KaijiBot flattens pure text `messages[].content` arrays into plain strings before sending the request.
- `plugins.entries.amazon-bedrock.config.discovery`: Bedrock auto-discovery settings root.
- `plugins.entries.amazon-bedrock.config.discovery.enabled`: turn implicit discovery on/off.
- `plugins.entries.amazon-bedrock.config.discovery.region`: AWS region for discovery.
- `plugins.entries.amazon-bedrock.config.discovery.providerFilter`: optional provider-id filter for targeted discovery.
- `plugins.entries.amazon-bedrock.config.discovery.refreshInterval`: polling interval for discovery refresh.
- `plugins.entries.amazon-bedrock.config.discovery.defaultContextWindow`: fallback context window for discovered models.
- `plugins.entries.amazon-bedrock.config.discovery.defaultMaxTokens`: fallback max output tokens for discovered models.

Set `MINIMAX_API_KEY`. Shortcuts:
`kaijibot onboard --auth-choice minimax-global-api` or
`kaijibot onboard --auth-choice minimax-cn-api`.
The model catalog defaults to M2.7 only.
On the Anthropic-compatible streaming path, KaijiBot disables MiniMax thinking
by default unless you explicitly set `thinking` yourself. `/fast on` or
`params.fastMode: true` rewrites `MiniMax-M2.7` to
`MiniMax-M2.7-highspeed`.

## Skills

```json5
{
  skills: {
    allowBundled: ["gemini", "peekaboo"],
    load: {
      extraDirs: ["~/Projects/agent-scripts/skills"],
    },
    install: {
      preferBrew: true,
      nodeManager: "npm", // npm | pnpm | yarn | bun
    },
    entries: {
      "image-lab": {
        apiKey: { source: "env", provider: "default", id: "GEMINI_API_KEY" }, // or plaintext string
        env: { GEMINI_API_KEY: "GEMINI_KEY_HERE" },
      },
      peekaboo: { enabled: true },
      sag: { enabled: false },
    },
  },
}
```

- `allowBundled`: optional allowlist for bundled skills only (managed/workspace skills unaffected).
- `load.extraDirs`: extra shared skill roots (lowest precedence).
- `install.preferBrew`: when true, prefer Homebrew installers when `brew` is
  available before falling back to other installer kinds.
- `install.nodeManager`: node installer preference for `metadata.kaijibot.install`
  specs (`npm` | `pnpm` | `yarn` | `bun`).
- `entries.<skillKey>.enabled: false` disables a skill even if bundled/installed.
- `entries.<skillKey>.apiKey`: convenience for skills declaring a primary env var (plaintext string or SecretRef object).

---

## Plugins

```json5
{
  plugins: {
    enabled: true,
    allow: ["voice-call"],
    deny: [],
    load: {
      paths: ["~/Projects/oss/voice-call-extension"],
    },
    entries: {
      "voice-call": {
        enabled: true,
        hooks: {
          allowPromptInjection: false,
        },
        config: { provider: "twilio" },
      },
    },
  },
}
```

- Loaded from `~/.kaijibot/extensions`, `<workspace>/.kaijibot/extensions`, plus `plugins.load.paths`.
- Discovery accepts native KaijiBot plugins plus compatible Codex bundles and Claude bundles, including manifestless Claude default-layout bundles.
- **Config changes require a gateway restart.**
- `allow`: optional allowlist (only listed plugins load). `deny` wins.
- `plugins.entries.<id>.apiKey`: plugin-level API key convenience field (when supported by the plugin).
- `plugins.entries.<id>.env`: plugin-scoped env var map.
- `plugins.entries.<id>.hooks.allowPromptInjection`: when `false`, core blocks `before_prompt_build` and ignores prompt-mutating fields from legacy `before_agent_start`, while preserving legacy `modelOverride` and `providerOverride`. Applies to native plugin hooks and supported bundle-provided hook directories.
- `plugins.entries.<id>.subagent.allowModelOverride`: explicitly trust this plugin to request per-run `provider` and `model` overrides for background subagent runs.
- `plugins.entries.<id>.subagent.allowedModels`: optional allowlist of canonical `provider/model` targets for trusted subagent overrides. Use `"*"` only when you intentionally want to allow any model.
- `plugins.entries.<id>.config`: plugin-defined config object (validated by native KaijiBot plugin schema when available).
- `plugins.entries.firecrawl.config.webFetch`: Firecrawl web-fetch provider settings.
  - `apiKey`: Firecrawl API key (accepts SecretRef). Falls back to `plugins.entries.firecrawl.config.webSearch.apiKey`, legacy `tools.web.fetch.firecrawl.apiKey`, or `FIRECRAWL_API_KEY` env var.
  - `baseUrl`: Firecrawl API base URL (default: `https://api.firecrawl.dev`).
  - `onlyMainContent`: extract only the main content from pages (default: `true`).
  - `maxAgeMs`: maximum cache age in milliseconds (default: `172800000` / 2 days).
  - `timeoutSeconds`: scrape request timeout in seconds (default: `60`).
- `plugins.entries.xai.config.xSearch`: xAI X Search (Grok web search) settings.
  - `enabled`: enable the X Search provider.
  - `model`: Grok model to use for search (e.g. `"grok-4-1-fast"`).
- `plugins.entries.memory-core.config.dreaming`: memory dreaming (experimental) settings. See [Dreaming](/concepts/dreaming) for phases and thresholds.
  - `enabled`: master dreaming switch (default `false`).
  - `frequency`: cron cadence for each full dreaming sweep (`"0 3 * * *"` by default).
  - phase policy and thresholds are implementation details (not user-facing config keys).
- Full memory config lives in [Memory configuration reference](/reference/memory-config):
  - `agents.defaults.memorySearch.*`
  - `memory.backend`
  - `memory.citations`
  - `memory.qmd.*`
  - `plugins.entries.memory-core.config.dreaming`
- Enabled Claude bundle plugins can also contribute embedded Pi defaults from `settings.json`; KaijiBot applies those as sanitized agent settings, not as raw KaijiBot config patches.
- `plugins.slots.memory`: pick the active memory plugin id, or `"none"` to disable memory plugins.
- `plugins.slots.contextEngine`: pick the active context engine plugin id; defaults to `"legacy"` unless you install and select another engine.
- `plugins.installs`: CLI-managed install metadata used by `kaijibot plugins update`.
  - Includes `source`, `spec`, `sourcePath`, `installPath`, `version`, `resolvedName`, `resolvedVersion`, `resolvedSpec`, `integrity`, `shasum`, `resolvedAt`, `installedAt`.
  - Treat `plugins.installs.*` as managed state; prefer CLI commands over manual edits.

See [Plugins](/tools/plugin).

## Browser

```json5
{
  browser: {
    enabled: true,
    evaluateEnabled: true,
    defaultProfile: "user",
    ssrfPolicy: {
      dangerouslyAllowPrivateNetwork: true, // default trusted-network mode
      // allowPrivateNetwork: true, // legacy alias
      // hostnameAllowlist: ["*.example.com", "example.com"],
      // allowedHostnames: ["localhost"],
    },
    profiles: {
      kaijibot: { cdpPort: 18800, color: "#FF4500" },
      work: { cdpPort: 18801, color: "#0066CC" },
      user: { driver: "existing-session", attachOnly: true, color: "#00AA00" },
      brave: {
        driver: "existing-session",
        attachOnly: true,
        userDataDir: "~/Library/Application Support/BraveSoftware/Brave-Browser",
        color: "#FB542B",
      },
      remote: { cdpUrl: "http://10.0.0.42:9222", color: "#00AA00" },
    },
    color: "#FF4500",
    // headless: false,
    // noSandbox: false,
    // extraArgs: [],
    // executablePath: "/Applications/Brave Browser.app/Contents/MacOS/Brave Browser",
    // attachOnly: false,
  },
}
```

- `evaluateEnabled: false` disables `act:evaluate` and `wait --fn`.
- `ssrfPolicy.dangerouslyAllowPrivateNetwork` defaults to `true` when unset (trusted-network model).
- Set `ssrfPolicy.dangerouslyAllowPrivateNetwork: false` for strict public-only browser navigation.
- In strict mode, remote CDP profile endpoints (`profiles.*.cdpUrl`) are subject to the same private-network blocking during reachability/discovery checks.
- `ssrfPolicy.allowPrivateNetwork` remains supported as a legacy alias.
- In strict mode, use `ssrfPolicy.hostnameAllowlist` and `ssrfPolicy.allowedHostnames` for explicit exceptions.
- Remote profiles are attach-only (start/stop/reset disabled).
- `profiles.*.cdpUrl` accepts `http://`, `https://`, `ws://`, and `wss://`.
  Use HTTP(S) when you want KaijiBot to discover `/json/version`; use WS(S)
  when your provider gives you a direct DevTools WebSocket URL.
- `existing-session` profiles are host-only and use Chrome MCP instead of CDP.
- `existing-session` profiles can set `userDataDir` to target a specific
  Chromium-based browser profile such as Brave or Edge.
- `existing-session` profiles keep the current Chrome MCP route limits:
  snapshot/ref-driven actions instead of CSS-selector targeting, one-file upload
  hooks, no dialog timeout overrides, no `wait --load networkidle`, and no
  `responsebody`, PDF export, download interception, or batch actions.
- Local managed `kaijibot` profiles auto-assign `cdpPort` and `cdpUrl`; only
  set `cdpUrl` explicitly for remote CDP.
- Auto-detect order: default browser if Chromium-based → Chrome → Brave → Edge → Chromium → Chrome Canary.
- Control service: loopback only (port derived from `gateway.port`, default `18791`).
- `extraArgs` appends extra launch flags to local Chromium startup (for example
  `--disable-gpu`, window sizing, or debug flags).

---

## UI

```json5
{
  ui: {
    seamColor: "#FF4500",
    assistant: {
      name: "KaijiBot",
      avatar: "CB", // emoji, short text, image URL, or data URI
    },
  },
}
```

- `seamColor`: accent color for native app UI chrome (Talk Mode bubble tint, etc.).
- `assistant`: Control UI identity override. Falls back to active agent identity.

---

## Gateway

```json5
{
  gateway: {
    mode: "local", // local | remote
    port: 18789,
    bind: "loopback",
    auth: {
      mode: "token", // none | token | password | trusted-proxy
      token: "your-token",
      // password: "your-password", // or KAIJIBOT_GATEWAY_PASSWORD
      // trustedProxy: { userHeader: "x-forwarded-user" }, // for mode=trusted-proxy; see /gateway/trusted-proxy-auth
      allowTailscale: true,
      rateLimit: {
        maxAttempts: 10,
        windowMs: 60000,
        lockoutMs: 300000,
        exemptLoopback: true,
      },
    },
    tailscale: {
      mode: "off", // off | serve | funnel
      resetOnExit: false,
    },
    controlUi: {
      enabled: true,
      basePath: "/kaijibot",
      // root: "dist/control-ui",
      // allowedOrigins: ["https://control.example.com"], // required for non-loopback Control UI
      // dangerouslyAllowHostHeaderOriginFallback: false, // dangerous Host-header origin fallback mode
      // allowInsecureAuth: false,
      // dangerouslyDisableDeviceAuth: false,
    },
    remote: {
      url: "ws://gateway.tailnet:18789",
      transport: "ssh", // ssh | direct
      token: "your-token",
      // password: "your-password",
    },
    trustedProxies: ["10.0.0.1"],
    // Optional. Default false.
    allowRealIpFallback: false,
    tools: {
      // Additional /tools/invoke HTTP denies
      deny: ["browser"],
      // Remove tools from the default HTTP deny list
      allow: ["gateway"],
    },
    push: {
      apns: {
        relay: {
          baseUrl: "https://relay.example.com",
          timeoutMs: 10000,
        },
      },
    },
  },
}
```

<Accordion title="Gateway field details">

- `mode`: `local` (run gateway) or `remote` (connect to remote gateway). Gateway refuses to start unless `local`.
- `port`: single multiplexed port for WS + HTTP. Precedence: `--port` > `KAIJIBOT_GATEWAY_PORT` > `gateway.port` > `18789`.
- `bind`: `auto`, `loopback` (default), `lan` (`0.0.0.0`), `tailnet` (Tailscale IP only), or `custom`.
- **Legacy bind aliases**: use bind mode values in `gateway.bind` (`auto`, `loopback`, `lan`, `tailnet`, `custom`), not host aliases (`0.0.0.0`, `127.0.0.1`, `localhost`, `::`, `::1`).
- **Docker note**: the default `loopback` bind listens on `127.0.0.1` inside the container. With Docker bridge networking (`-p 18789:18789`), traffic arrives on `eth0`, so the gateway is unreachable. Use `--network host`, or set `bind: "lan"` (or `bind: "custom"` with `customBindHost: "0.0.0.0"`) to listen on all interfaces.
- **Auth**: required by default. Non-loopback binds require gateway auth. In practice that means a shared token/password or an identity-aware reverse proxy with `gateway.auth.mode: "trusted-proxy"`. Onboarding wizard generates a token by default.
- If both `gateway.auth.token` and `gateway.auth.password` are configured (including SecretRefs), set `gateway.auth.mode` explicitly to `token` or `password`. Startup and service install/repair flows fail when both are configured and mode is unset.
- `gateway.auth.mode: "none"`: explicit no-auth mode. Use only for trusted local loopback setups; this is intentionally not offered by onboarding prompts.
- `gateway.auth.mode: "trusted-proxy"`: delegate auth to an identity-aware reverse proxy and trust identity headers from `gateway.trustedProxies` (see [Trusted Proxy Auth](/gateway/trusted-proxy-auth)). This mode expects a **non-loopback** proxy source; same-host loopback reverse proxies do not satisfy trusted-proxy auth.
- `gateway.auth.allowTailscale`: when `true`, Tailscale Serve identity headers can satisfy Control UI/WebSocket auth (verified via `tailscale whois`). HTTP API endpoints do **not** use that Tailscale header auth; they follow the gateway's normal HTTP auth mode instead. This tokenless flow assumes the gateway host is trusted. Defaults to `true` when `tailscale.mode = "serve"`.
- `gateway.auth.rateLimit`: optional failed-auth limiter. Applies per client IP and per auth scope (shared-secret and device-token are tracked independently). Blocked attempts return `429` + `Retry-After`.
  - On the async Tailscale Serve Control UI path, failed attempts for the same `{scope, clientIp}` are serialized before the failure write. Concurrent bad attempts from the same client can therefore trip the limiter on the second request instead of both racing through as plain mismatches.
  - `gateway.auth.rateLimit.exemptLoopback` defaults to `true`; set `false` when you intentionally want localhost traffic rate-limited too (for test setups or strict proxy deployments).
- Browser-origin WS auth attempts are always throttled with loopback exemption disabled (defense-in-depth against browser-based localhost brute force).
- On loopback, those browser-origin lockouts are isolated per normalized `Origin`
  value, so repeated failures from one localhost origin do not automatically
  lock out a different origin.
- `tailscale.mode`: `serve` (tailnet only, loopback bind) or `funnel` (public, requires auth).
- `controlUi.allowedOrigins`: explicit browser-origin allowlist for Gateway WebSocket connects. Required when browser clients are expected from non-loopback origins.
- `controlUi.dangerouslyAllowHostHeaderOriginFallback`: dangerous mode that enables Host-header origin fallback for deployments that intentionally rely on Host-header origin policy.
- `remote.transport`: `ssh` (default) or `direct` (ws/wss). For `direct`, `remote.url` must be `ws://` or `wss://`.
- `KAIJIBOT_ALLOW_INSECURE_PRIVATE_WS=1`: client-side break-glass override that allows plaintext `ws://` to trusted private-network IPs; default remains loopback-only for plaintext.
- `gateway.remote.token` / `.password` are remote-client credential fields. They do not configure gateway auth by themselves.
- `gateway.push.apns.relay.baseUrl`: base HTTPS URL for the external APNs relay used by official/TestFlight iOS builds after they publish relay-backed registrations to the gateway. This URL must match the relay URL compiled into the iOS build.
- `gateway.push.apns.relay.timeoutMs`: gateway-to-relay send timeout in milliseconds. Defaults to `10000`.
- Relay-backed registrations are delegated to a specific gateway identity. The paired iOS app fetches `gateway.identity.get`, includes that identity in the relay registration, and forwards a registration-scoped send grant to the gateway. Another gateway cannot reuse that stored registration.
- `KAIJIBOT_APNS_RELAY_BASE_URL` / `KAIJIBOT_APNS_RELAY_TIMEOUT_MS`: temporary env overrides for the relay config above.
- `KAIJIBOT_APNS_RELAY_ALLOW_HTTP=true`: development-only escape hatch for loopback HTTP relay URLs. Production relay URLs should stay on HTTPS.
- `gateway.channelHealthCheckMinutes`: channel health-monitor interval in minutes. Set `0` to disable health-monitor restarts globally. Default: `5`.
- `gateway.channelStaleEventThresholdMinutes`: stale-socket threshold in minutes. Keep this greater than or equal to `gateway.channelHealthCheckMinutes`. Default: `30`.
- `gateway.channelMaxRestartsPerHour`: maximum health-monitor restarts per channel/account in a rolling hour. Default: `10`.
- `channels.<provider>.healthMonitor.enabled`: per-channel opt-out for health-monitor restarts while keeping the global monitor enabled.
- `channels.<provider>.accounts.<accountId>.healthMonitor.enabled`: per-account override for multi-account channels. When set, it takes precedence over the channel-level override.
- Local gateway call paths can use `gateway.remote.*` as fallback only when `gateway.auth.*` is unset.
- If `gateway.auth.token` / `gateway.auth.password` is explicitly configured via SecretRef and unresolved, resolution fails closed (no remote fallback masking).
- `trustedProxies`: reverse proxy IPs that terminate TLS or inject forwarded-client headers. Only list proxies you control. Loopback entries are still valid for same-host proxy/local-detection setups (for example Tailscale Serve or a local reverse proxy), but they do **not** make loopback requests eligible for `gateway.auth.mode: "trusted-proxy"`.
- `allowRealIpFallback`: when `true`, the gateway accepts `X-Real-IP` if `X-Forwarded-For` is missing. Default `false` for fail-closed behavior.
- `gateway.tools.deny`: extra tool names blocked for HTTP `POST /tools/invoke` (extends default deny list).
- `gateway.tools.allow`: remove tool names from the default HTTP deny list.

</Accordion>

### OpenAI-compatible endpoints

- Chat Completions: disabled by default. Enable with `gateway.http.endpoints.chatCompletions.enabled: true`.
- Responses API: `gateway.http.endpoints.responses.enabled`.
- Responses URL-input hardening:
  - `gateway.http.endpoints.responses.maxUrlParts`
  - `gateway.http.endpoints.responses.files.urlAllowlist`
  - `gateway.http.endpoints.responses.images.urlAllowlist`
    Empty allowlists are treated as unset; use `gateway.http.endpoints.responses.files.allowUrl=false`
    and/or `gateway.http.endpoints.responses.images.allowUrl=false` to disable URL fetching.
- Optional response hardening header:
  - `gateway.http.securityHeaders.strictTransportSecurity` (set only for HTTPS origins you control; see [Trusted Proxy Auth](/gateway/trusted-proxy-auth#tls-termination-and-hsts))

### Multi-instance isolation

Run multiple gateways on one host with unique ports and state dirs:

```bash
KAIJIBOT_CONFIG_PATH=~/.kaijibot/a.json \
KAIJIBOT_STATE_DIR=~/.kaijibot-a \
kaijibot gateway --port 19001
```

Convenience flags: `--dev` (uses `~/.kaijibot-dev` + port `19001`), `--profile <name>` (uses `~/.kaijibot-<name>`).

See [Multiple Gateways](/gateway/multiple-gateways).

### `gateway.tls`

```json5
{
  gateway: {
    tls: {
      enabled: false,
      autoGenerate: false,
      certPath: "/etc/kaijibot/tls/server.crt",
      keyPath: "/etc/kaijibot/tls/server.key",
      caPath: "/etc/kaijibot/tls/ca-bundle.crt",
    },
  },
}
```

- `enabled`: enables TLS termination at the gateway listener (HTTPS/WSS) (default: `false`).
- `autoGenerate`: auto-generates a local self-signed cert/key pair when explicit files are not configured; for local/dev use only.
- `certPath`: filesystem path to the TLS certificate file.
- `keyPath`: filesystem path to the TLS private key file; keep permission-restricted.
- `caPath`: optional CA bundle path for client verification or custom trust chains.

### `gateway.reload`

```json5
{
  gateway: {
    reload: {
      mode: "hybrid", // off | restart | hot | hybrid
      debounceMs: 500,
      deferralTimeoutMs: 300000,
    },
  },
}
```

- `mode`: controls how config edits are applied at runtime.
  - `"off"`: ignore live edits; changes require an explicit restart.
  - `"restart"`: always restart the gateway process on config change.
  - `"hot"`: apply changes in-process without restarting.
  - `"hybrid"` (default): try hot reload first; fall back to restart if required.
- `debounceMs`: debounce window in ms before config changes are applied (non-negative integer).
- `deferralTimeoutMs`: maximum time in ms to wait for in-flight operations before forcing a restart (default: `300000` = 5 minutes).

---

## Hooks

```json5
{
  hooks: {
    enabled: true,
    token: "shared-secret",
    path: "/hooks",
    maxBodyBytes: 262144,
    defaultSessionKey: "hook:ingress",
    allowRequestSessionKey: false,
    allowedSessionKeyPrefixes: ["hook:"],
    allowedAgentIds: ["hooks", "main"],
    presets: ["gmail"],
    transformsDir: "~/.kaijibot/hooks/transforms",
    mappings: [
      {
        match: { path: "gmail" },
        action: "agent",
        agentId: "hooks",
        wakeMode: "now",
        name: "Gmail",
        sessionKey: "hook:gmail:{{messages[0].id}}",
        messageTemplate: "From: {{messages[0].from}}\nSubject: {{messages[0].subject}}\n{{messages[0].snippet}}",
        deliver: true,
        channel: "last",
        model: "openai/gpt-5.4-mini",
      },
    ],
  },
}
```

Auth: `Authorization: Bearer <token>` or `x-kaijibot-token: <token>`.
Query-string hook tokens are rejected.

Validation and safety notes:

- `hooks.enabled=true` requires a non-empty `hooks.token`.
- `hooks.token` must be **distinct** from `gateway.auth.token`; reusing the Gateway token is rejected.
- `hooks.path` cannot be `/`; use a dedicated subpath such as `/hooks`.
- If `hooks.allowRequestSessionKey=true`, constrain `hooks.allowedSessionKeyPrefixes` (for example `["hook:"]`).

**Endpoints:**

- `POST /hooks/wake` → `{ text, mode?: "now"|"next-heartbeat" }`
- `POST /hooks/agent` → `{ message, name?, agentId?, sessionKey?, wakeMode?, deliver?, channel?, to?, model?, thinking?, timeoutSeconds? }`
  - `sessionKey` from request payload is accepted only when `hooks.allowRequestSessionKey=true` (default: `false`).
- `POST /hooks/<name>` → resolved via `hooks.mappings`

<Accordion title="Mapping details">

- `match.path` matches sub-path after `/hooks` (e.g. `/hooks/gmail` → `gmail`).
- `match.source` matches a payload field for generic paths.
- Templates like `{{messages[0].subject}}` read from the payload.
- `transform` can point to a JS/TS module returning a hook action.
  - `transform.module` must be a relative path and stays within `hooks.transformsDir` (absolute paths and traversal are rejected).
- `agentId` routes to a specific agent; unknown IDs fall back to default.
- `allowedAgentIds`: restricts explicit routing (`*` or omitted = allow all, `[]` = deny all).
- `defaultSessionKey`: optional fixed session key for hook agent runs without explicit `sessionKey`.
- `allowRequestSessionKey`: allow `/hooks/agent` callers to set `sessionKey` (default: `false`).
- `allowedSessionKeyPrefixes`: optional prefix allowlist for explicit `sessionKey` values (request + mapping), e.g. `["hook:"]`.
- `deliver: true` sends final reply to a channel; `channel` defaults to `last`.
- `model` overrides LLM for this hook run (must be allowed if model catalog is set).

</Accordion>

### Gmail integration

```json5
{
  hooks: {
    gmail: {
      account: "kaijibot@gmail.com",
      topic: "projects/<project-id>/topics/gog-gmail-watch",
      subscription: "gog-gmail-watch-push",
      pushToken: "shared-push-token",
      hookUrl: "http://127.0.0.1:18789/hooks/gmail",
      includeBody: true,
      maxBytes: 20000,
      renewEveryMinutes: 720,
      serve: { bind: "127.0.0.1", port: 8788, path: "/" },
      tailscale: { mode: "funnel", path: "/gmail-pubsub" },
      model: "openrouter/meta-llama/llama-3.3-70b-instruct:free",
      thinking: "off",
    },
  },
}
```

- Gateway auto-starts `gog gmail watch serve` on boot when configured. Set `KAIJIBOT_SKIP_GMAIL_WATCHER=1` to disable.
- Don't run a separate `gog gmail watch serve` alongside the Gateway.

---

## Canvas host

```json5
{
  canvasHost: {
    root: "~/.kaijibot/workspace/canvas",
    liveReload: true,
    // enabled: false, // or KAIJIBOT_SKIP_CANVAS_HOST=1
  },
}
```

- Serves agent-editable HTML/CSS/JS and A2UI over HTTP under the Gateway port:
  - `http://<gateway-host>:<gateway.port>/__kaijibot__/canvas/`
  - `http://<gateway-host>:<gateway.port>/__kaijibot__/a2ui/`
- Local-only: keep `gateway.bind: "loopback"` (default).
- Non-loopback binds: canvas routes require Gateway auth (token/password/trusted-proxy), same as other Gateway HTTP surfaces.
- Node WebViews typically don't send auth headers; after a node is paired and connected, the Gateway advertises node-scoped capability URLs for canvas/A2UI access.
- Capability URLs are bound to the active node WS session and expire quickly. IP-based fallback is not used.
- Injects live-reload client into served HTML.
- Auto-creates starter `index.html` when empty.
- Also serves A2UI at `/__kaijibot__/a2ui/`.
- Changes require a gateway restart.
- Disable live reload for large directories or `EMFILE` errors.

---

## Discovery

### mDNS (Bonjour)

```json5
{
  discovery: {
    mdns: {
      mode: "minimal", // minimal | full | off
    },
  },
}
```

- `minimal` (default): omit `cliPath` + `sshPort` from TXT records.
- `full`: include `cliPath` + `sshPort`.
- Hostname defaults to `kaijibot`. Override with `KAIJIBOT_MDNS_HOSTNAME`.

### Wide-area (DNS-SD)

```json5
{
  discovery: {
    wideArea: { enabled: true },
  },
}
```

Writes a unicast DNS-SD zone under `~/.kaijibot/dns/`. For cross-network discovery, pair with a DNS server (CoreDNS recommended) + Tailscale split DNS.

Setup: `kaijibot dns setup --apply`.

---

## Environment

### `env` (inline env vars)

```json5
{
  env: {
    OPENROUTER_API_KEY: "sk-or-...",
    vars: {
      GROQ_API_KEY: "gsk-...",
    },
    shellEnv: {
      enabled: true,
      timeoutMs: 15000,
    },
  },
}
```

- Inline env vars are only applied if the process env is missing the key.
- `.env` files: CWD `.env` + `~/.kaijibot/.env` (neither overrides existing vars).
- `shellEnv`: imports missing expected keys from your login shell profile.
- See [Environment](/help/environment) for full precedence.

### Env var substitution

Reference env vars in any config string with `${VAR_NAME}`:

```json5
{
  gateway: {
    auth: { token: "${KAIJIBOT_GATEWAY_TOKEN}" },
  },
}
```

- Only uppercase names matched: `[A-Z_][A-Z0-9_]*`.
- Missing/empty vars throw an error at config load.
- Escape with `$${VAR}` for a literal `${VAR}`.
- Works with `$include`.

---

## Secrets

Secret refs are additive: plaintext values still work.

### `SecretRef`

Use one object shape:

```json5
{ source: "env" | "file" | "exec", provider: "default", id: "..." }
```

Validation:

- `provider` pattern: `^[a-z][a-z0-9_-]{0,63}$`
- `source: "env"` id pattern: `^[A-Z][A-Z0-9_]{0,127}$`
- `source: "file"` id: absolute JSON pointer (for example `"/providers/openai/apiKey"`)
- `source: "exec"` id pattern: `^[A-Za-z0-9][A-Za-z0-9._:/-]{0,255}$`
- `source: "exec"` ids must not contain `.` or `..` slash-delimited path segments (for example `a/../b` is rejected)

### Supported credential surface

- Canonical matrix: [SecretRef Credential Surface](/reference/secretref-credential-surface)
- `secrets apply` targets supported `kaijibot.json` credential paths.
- `auth-profiles.json` refs are included in runtime resolution and audit coverage.

### Secret providers config

```json5
{
  secrets: {
    providers: {
      default: { source: "env" }, // optional explicit env provider
      filemain: {
        source: "file",
        path: "~/.kaijibot/secrets.json",
        mode: "json",
        timeoutMs: 5000,
      },
      vault: {
        source: "exec",
        command: "/usr/local/bin/kaijibot-vault-resolver",
        passEnv: ["PATH", "VAULT_ADDR"],
      },
    },
    defaults: {
      env: "default",
      file: "filemain",
      exec: "vault",
    },
  },
}
```

Notes:

- `file` provider supports `mode: "json"` and `mode: "singleValue"` (`id` must be `"value"` in singleValue mode).
- `exec` provider requires an absolute `command` path and uses protocol payloads on stdin/stdout.
- By default, symlink command paths are rejected. Set `allowSymlinkCommand: true` to allow symlink paths while validating the resolved target path.
- If `trustedDirs` is configured, the trusted-dir check applies to the resolved target path.
- `exec` child environment is minimal by default; pass required variables explicitly with `passEnv`.
- Secret refs are resolved at activation time into an in-memory snapshot, then request paths read the snapshot only.
- Active-surface filtering applies during activation: unresolved refs on enabled surfaces fail startup/reload, while inactive surfaces are skipped with diagnostics.

---

## Auth storage

```json5
{
  auth: {
    profiles: {
      "anthropic:default": { provider: "anthropic", mode: "api_key" },
      "anthropic:work": { provider: "anthropic", mode: "api_key" },
      "openai-codex:personal": { provider: "openai-codex", mode: "oauth" },
    },
    order: {
      anthropic: ["anthropic:default", "anthropic:work"],
      "openai-codex": ["openai-codex:personal"],
    },
  },
}
```

- Per-agent profiles are stored at `<agentDir>/auth-profiles.json`.
- `auth-profiles.json` supports value-level refs (`keyRef` for `api_key`, `tokenRef` for `token`) for static credential modes.
- OAuth-mode profiles (`auth.profiles.<id>.mode = "oauth"`) do not support SecretRef-backed auth-profile credentials.
- Static runtime credentials come from in-memory resolved snapshots; legacy static `auth.json` entries are scrubbed when discovered.
- Legacy OAuth imports from `~/.kaijibot/credentials/oauth.json`.
- See [OAuth](/concepts/oauth).
- Secrets runtime behavior and `audit/configure/apply` tooling: [Secrets Management](/gateway/secrets).

### `auth.cooldowns`

```json5
{
  auth: {
    cooldowns: {
      billingBackoffHours: 5,
      billingBackoffHoursByProvider: { anthropic: 3, openai: 8 },
      billingMaxHours: 24,
      authPermanentBackoffMinutes: 10,
      authPermanentMaxMinutes: 60,
      failureWindowHours: 24,
      overloadedProfileRotations: 1,
      overloadedBackoffMs: 0,
      rateLimitedProfileRotations: 1,
    },
  },
}
```

- `billingBackoffHours`: base backoff in hours when a profile fails due to true
  billing/insufficient-credit errors (default: `5`). Explicit billing text can
  still land here even on `401`/`403` responses, but provider-specific text
  matchers stay scoped to the provider that owns them (for example OpenRouter
  `Key limit exceeded`). Retryable HTTP `402` usage-window or
  organization/workspace spend-limit messages stay in the `rate_limit` path
  instead.
- `billingBackoffHoursByProvider`: optional per-provider overrides for billing backoff hours.
- `billingMaxHours`: cap in hours for billing backoff exponential growth (default: `24`).
- `authPermanentBackoffMinutes`: base backoff in minutes for high-confidence `auth_permanent` failures (default: `10`).
- `authPermanentMaxMinutes`: cap in minutes for `auth_permanent` backoff growth (default: `60`).
- `failureWindowHours`: rolling window in hours used for backoff counters (default: `24`).
- `overloadedProfileRotations`: maximum same-provider auth-profile rotations for overloaded errors before switching to model fallback (default: `1`). Provider-busy shapes such as `ModelNotReadyException` land here.
- `overloadedBackoffMs`: fixed delay before retrying an overloaded provider/profile rotation (default: `0`).
- `rateLimitedProfileRotations`: maximum same-provider auth-profile rotations for rate-limit errors before switching to model fallback (default: `1`). That rate-limit bucket includes provider-shaped text such as `Too many concurrent requests`, `ThrottlingException`, `concurrency limit reached`, `workers_ai ... quota limit exceeded`, and `resource exhausted`.

## Logging

```json5
{
  logging: {
    level: "info",
    file: "/tmp/kaijibot/kaijibot.log",

    checkOnStart: true,

    auto: {
      enabled: false,
      stableDelayHours: 6,
      stableJitterHours: 12,

## ACP

```json5
{
  acp: {
    enabled: false,
    dispatch: { enabled: true },
    backend: "acpx",
    defaultAgent: "main",
    allowedAgents: ["main", "ops"],
    maxConcurrentSessions: 10,

    stream: {
      coalesceIdleMs: 50,
      maxChunkChars: 1000,
      repeatSuppression: true,

    },
  },
}
```

- `enabled`: global ACP feature gate (default: `false`).

## CLI

```json5
{
  cli: {
    banner: {
      taglineMode: "off", // random | default | off
    },
  },
}
```

- `cli.banner.taglineMode` controls banner tagline style:
  - `"random"` (default): rotating funny/seasonal taglines.
  - `"default"`: fixed neutral tagline (`All your chats, one KaijiBot.`).
  - `"off"`: no tagline text (banner title/version still shown).
- To hide the entire banner (not just taglines), set env `KAIJIBOT_HIDE_BANNER=1`.

---

## Wizard

Metadata written by CLI guided setup flows (`onboard`, `configure`, `doctor`):

```json5
{
  wizard: {
    lastRunAt: "2026-01-01T00:00:00.000Z",
    lastRunVersion: "2026.1.4",
    lastRunCommit: "abc1234",
    lastRunCommand: "configure",
    lastRunMode: "local",
  },
}
```

---

## Identity

See `agents.list` identity fields under [Agent defaults](#agent-defaults).

---

## Bridge (legacy, removed)

Current builds no longer include the TCP bridge. Nodes connect over the Gateway WebSocket. `bridge.*` keys are no longer part of the config schema (validation fails until removed; `kaijibot doctor --fix` can strip unknown keys).

<Accordion title="Legacy bridge config (historical reference)">

```json
{
  "bridge": {
    "enabled": true,
    "port": 18790,
    "bind": "tailnet",
    "tls": {
      "enabled": true,
      "autoGenerate": true
    }
  }
}
```

</Accordion>

---

## Cron

```json5
{
  cron: {
    enabled: true,
    maxConcurrentRuns: 2,
    webhook: "https://example.invalid/legacy", // deprecated fallback for stored notify:true jobs
    webhookToken: "replace-with-dedicated-token", // optional bearer token for outbound webhook auth
    sessionRetention: "24h", // duration string or false
    runLog: {
      maxBytes: "2mb", // default 2_000_000 bytes
      keepLines: 2000, // default 2000
    },
  },
}
```

- `sessionRetention`: how long to keep completed isolated cron run sessions before pruning from `sessions.json`. Also controls cleanup of archived deleted cron transcripts. Default: `24h`; set `false` to disable.
- `runLog.maxBytes`: max size per run log file (`cron/runs/<jobId>.jsonl`) before pruning. Default: `2_000_000` bytes.
- `runLog.keepLines`: newest lines retained when run-log pruning is triggered. Default: `2000`.
- `webhookToken`: bearer token used for cron webhook POST delivery (`delivery.mode = "webhook"`), if omitted no auth header is sent.
- `webhook`: deprecated legacy fallback webhook URL (http/https) used only for stored jobs that still have `notify: true`.

### `cron.retry`

```json5
{
  cron: {
    retry: {
      maxAttempts: 3,
      backoffMs: [30000, 60000, 300000],
      retryOn: ["rate_limit", "overloaded", "network", "timeout", "server_error"],
    },
  },
}
```

- `maxAttempts`: maximum retries for one-shot jobs on transient errors (default: `3`; range: `0`–`10`).
- `backoffMs`: array of backoff delays in ms for each retry attempt (default: `[30000, 60000, 300000]`; 1–10 entries).
- `retryOn`: error types that trigger retries — `"rate_limit"`, `"overloaded"`, `"network"`, `"timeout"`, `"server_error"`. Omit to retry all transient types.

Applies only to one-shot cron jobs. Recurring jobs use separate failure handling.

### `cron.failureAlert`

```json5
{
  cron: {
    failureAlert: {
      enabled: false,
      after: 3,
      cooldownMs: 3600000,
      mode: "announce",
      accountId: "main",
    },
  },
}
```

- `enabled`: enable failure alerts for cron jobs (default: `false`).
- `after`: consecutive failures before an alert fires (positive integer, min: `1`).
- `cooldownMs`: minimum milliseconds between repeated alerts for the same job (non-negative integer).
- `mode`: delivery mode — `"announce"` sends via a channel message; `"webhook"` posts to the configured webhook.
- `accountId`: optional account or channel id to scope alert delivery.

### `cron.failureDestination`

```json5
{
  cron: {
    failureDestination: {
      mode: "announce",
      channel: "last",
      to: "channel:C1234567890",
      accountId: "main",
    },
  },
}
```

- Default destination for cron failure notifications across all jobs.
- `mode`: `"announce"` or `"webhook"`; defaults to `"announce"` when enough target data exists.
- `channel`: channel override for announce delivery. `"last"` reuses the last known delivery channel.
- `to`: explicit announce target or webhook URL. Required for webhook mode.
- `accountId`: optional account override for delivery.
- Per-job `delivery.failureDestination` overrides this global default.
- When neither global nor per-job failure destination is set, jobs that already deliver via `announce` fall back to that primary announce target on failure.
- `delivery.failureDestination` is only supported for `sessionTarget="isolated"` jobs unless the job's primary `delivery.mode` is `"webhook"`.

See [Cron Jobs](/automation/cron-jobs). Isolated cron executions are tracked as [background tasks](/automation/tasks).

## Config includes (`$include`)

Split config into multiple files:

```json5
// ~/.kaijibot/kaijibot.json
{
  gateway: { port: 18789 },
  agents: { $include: "./agents.json5" },
  broadcast: {
    $include: ["./clients/mueller.json5", "./clients/schmidt.json5"],
  },
}
```

**Merge behavior:**

- Single file: replaces the containing object.
- Array of files: deep-merged in order (later overrides earlier).
- Sibling keys: merged after includes (override included values).
- Nested includes: up to 10 levels deep.
- Paths: resolved relative to the including file, but must stay inside the top-level config directory (`dirname` of `kaijibot.json`). Absolute/`../` forms are allowed only when they still resolve inside that boundary.
- Errors: clear messages for missing files, parse errors, and circular includes.
