* security: add mDNS discovery config to reduce information disclosure
mDNS broadcasts can expose sensitive operational details like filesystem
paths (cliPath) and SSH availability (sshPort) to anyone on the local
network. This information aids reconnaissance and should be minimized
for gateways exposed beyond trusted networks.
Changes:
- Add discovery.mdns.enabled config option to disable mDNS entirely
- Add discovery.mdns.minimal option to omit cliPath/sshPort from TXT records
- Update security docs with operational security guidance
Minimal mode still broadcasts enough for device discovery (role, gatewayPort,
transport) while omitting details that help map the host environment.
Apps that need CLI path can fetch it via the authenticated WebSocket.
* fix: default mDNS discovery mode to minimal (#1882) (thanks @orlyjamie)

The previous check used includes("win") which incorrectly matched
"darwin" (macOS) because it contains "win". This caused cmd.exe to be
used on macOS instead of /bin/sh.
* fix(bluebubbles): prefer DM resolution + hide routing markers
* fix(bluebubbles): prevent message routing to group chats when targeting phone numbers
When sending a message to a phone number like +12622102921, the
resolveChatGuidForTarget function was finding and returning a GROUP
CHAT containing that phone number instead of a direct DM chat.
The bug was in the participantMatch fallback logic which matched ANY
chat containing the phone number as a participant, including groups.
This fix adds a check to ensure participantMatch only considers DM
chats (identified by ';-;' separator in the chat GUID). Group chats
(identified by ';+;' separator) are now explicitly excluded from
handle-based matching.
If a phone number only exists in a group chat (no direct DM exists),
the function now correctly returns null, which causes the send to
fail with a clear error rather than accidentally messaging a group.
Added test case to verify this behavior.
* feat(bluebubbles): auto-create new DM chats when sending to unknown phone numbers
When sending to a phone number that doesn't have an existing chat,
instead of failing with 'chatGuid not found', now automatically creates
a new chat using the /api/v1/chat/new endpoint.
- Added createNewChatWithMessage() helper function
- When resolveChatGuidForTarget returns null for a handle target,
uses the new chat endpoint with addresses array and message
- Includes helpful error message if Private API isn't enabled
- Only applies to handle targets (phone numbers), not group chats
* fix(bluebubbles): hide internal routing metadata in cross-context markers
When sending cross-context messages via BlueBubbles, the origin marker was
exposing internal chat_guid routing info like '[from bluebubbles:chat_guid:any;-;+19257864429]'.
This adds a formatTargetDisplay() function to the BlueBubbles plugin that:
- Extracts phone numbers from chat_guid formats (iMessage;-;+1234567890 -> +1234567890)
- Normalizes handles for clean display
- Avoids returning raw chat_guid formats containing internal routing metadata
Now cross-context markers show clean identifiers like '[from +19257864429]' instead
of exposing internal routing details to recipients.
* fix: prevent cross-context decoration on direct message tool sends
Two fixes:
1. Cross-context decoration (e.g., '[from +19257864429]' prefix) was being
added to ALL messages sent to a different target, even when the agent
was just composing a new message via the message tool. This decoration
should only be applied when forwarding/relaying messages between chats.
Fix: Added skipCrossContextDecoration flag to ChannelThreadingToolContext.
The message tool now sets this flag to true, so direct sends don't get
decorated. The buildCrossContextDecoration function checks this flag
and returns null when set.
2. Aborted requests were still completing because the abort signal wasn't
being passed through the message tool execution chain.
Fix: Added abortSignal propagation from message tool → runMessageAction →
executeSendAction → sendMessage → deliverOutboundPayloads. Added abort
checks at key points in the chain to fail fast when aborted.
Files changed:
- src/channels/plugins/types.core.ts: Added skipCrossContextDecoration field
- src/infra/outbound/outbound-policy.ts: Check skip flag before decorating
- src/agents/tools/message-tool.ts: Set skip flag, accept and pass abort signal
- src/infra/outbound/message-action-runner.ts: Pass abort signal through
- src/infra/outbound/outbound-send-service.ts: Check and pass abort signal
- src/infra/outbound/message.ts: Pass abort signal to delivery
* fix(bluebubbles): preserve friendly display names in formatTargetDisplay
* feat: add chunking mode for outbound messages
- Introduced `chunkMode` option in various account configurations to allow splitting messages by "length" or "newline".
- Updated message processing to handle chunking based on the selected mode.
- Added tests for new chunking functionality, ensuring correct behavior for both modes.
* feat: enhance chunking mode documentation and configuration
- Added `chunkMode` option to the BlueBubbles account configuration, allowing users to choose between "length" and "newline" for message chunking.
- Updated documentation to clarify the behavior of the `chunkMode` setting.
- Adjusted account merging logic to incorporate the new `chunkMode` configuration.
* refactor: simplify chunk mode handling for BlueBubbles
- Removed `chunkMode` configuration from various account schemas and types, centralizing chunk mode logic to BlueBubbles only.
- Updated `processMessage` to default to "newline" for BlueBubbles chunking.
- Adjusted tests to reflect changes in chunk mode handling for BlueBubbles, ensuring proper functionality.
* fix: update default chunk mode to 'length' for BlueBubbles
- Changed the default value of `chunkMode` from 'newline' to 'length' in the BlueBubbles configuration and related processing functions.
- Updated documentation to reflect the new default behavior for chunking messages.
- Adjusted tests to ensure the correct default value is returned for BlueBubbles chunk mode.
* feat(discord): add exec approval forwarding to DMs
Add support for forwarding exec approval requests to Discord DMs,
allowing users to approve/deny command execution via interactive buttons.
Features:
- New DiscordExecApprovalHandler that connects to gateway and listens
for exec.approval.requested/resolved events
- Sends DMs with embeds showing command details and 3 buttons:
Allow once, Always allow, Deny
- Configurable via channels.discord.execApprovals with:
- enabled: boolean
- approvers: Discord user IDs to notify
- agentFilter: only forward for specific agents
- sessionFilter: only forward for matching session patterns
- Updates message embed when approval is resolved or expires
Also fixes exec completion routing: when async exec completes after
approval, the heartbeat now uses a specialized prompt to ensure the
model relays the result to the user instead of responding HEARTBEAT_OK.

* fix: reduce log noise for node disconnect/late invoke errors
- Handle both 'node not connected' and 'node disconnected' errors at info level
- Return success with late:true for unknown invoke IDs instead of error
- Add 30-second throttle to skills change listener to prevent rapid-fire probes
- Add tests for isNodeUnavailableError and late invoke handling
* fix: clean up skills refresh timer and listener on shutdown
Store the return value from registerSkillsChangeListener() and call it
on gateway shutdown. Also clear any pending refresh timer. This follows
the same pattern used for agentUnsub and heartbeatUnsub.
* refactor: simplify KISS/YAGNI - inline checks, remove unit tests for internal utilities
* fix: reduce gateway log noise (#1607) (thanks @petter-b)

In containers, PIDs can be recycled quickly after restarts. When a container
restarts, a different process might get the same PID as the previous gateway,
causing the lock check to incorrectly think the old gateway is still running.
This fix adds isGatewayProcess() which verifies on Linux that the PID actually
belongs to a clawdbot gateway by checking /proc/PID/cmdline. If the cmdline
doesn't contain 'clawdbot' or 'gateway', we assume the lock is stale.
Fixes gateway boot-loop in Docker/Fly.io deployments.
* feat: skip heartbeat API calls when HEARTBEAT.md is effectively empty
- Added isHeartbeatContentEffectivelyEmpty() to detect files with only headers/comments
- Modified runHeartbeatOnce() to check HEARTBEAT.md content before polling the LLM
- Returns early with 'empty-heartbeat-file' reason when no actionable tasks exist
- Preserves existing behavior when file is missing (lets LLM decide)
- Added comprehensive test coverage for empty file detection
- Saves API calls/costs when heartbeat file has no meaningful content
* chore: update HEARTBEAT.md template to be effectively empty by default
Changed instruction text to comment format so new workspaces benefit from
heartbeat optimization immediately. Users still get clear guidance on usage.
* fix: only treat markdown headers (# followed by space) as comments, not #TODO etc
* refactor: simplify regex per code review suggestion
* docs: clarify heartbeat empty file behavior (#1535) (thanks @JustYannicc)

To avoid permission denied errors when modifying Tailscale configuration (serve/funnel),
we now attempt the command directly first. If it fails, we catch the error and retry
with `sudo -n`. This preserves existing behavior for users where it works, but
attempts to escalate privileges (non-interactively) if needed.
- Added `execWithSudoFallback` helper in `src/infra/tailscale.ts`.
- Updated `ensureFunnel`, `enableTailscaleServe`, `disableTailscaleServe`,
`enableTailscaleFunnel`, and `disableTailscaleFunnel` to use the fallback helper.
- Added tests in `src/infra/tailscale.test.ts` to verify fallback behavior.
To avoid permission denied errors when modifying Tailscale configuration (serve/funnel),
we now prepend `sudo -n` to these commands. This ensures that if the user has appropriate
sudo privileges (specifically passwordless for these commands or generally), the operation
succeeds. If sudo fails (e.g. requires password non-interactively), it will throw an error
which is caught and logged as a warning, preserving existing behavior but attempting to escalate privileges first.
- Updated `ensureFunnel` to use `sudo -n` for the enabling step.
- Updated `enableTailscaleServe`, `disableTailscaleServe`, `enableTailscaleFunnel`, `disableTailscaleFunnel` to use `sudo -n`.
