Add an off switch for agent messages (global, per agent, per workspace) - #16551
Conversation
agentMessages.enabled (cmux.json and Settings > Automation) turns agent messages off for all of cmux: sends fail with a clear error, nothing is stored, and queued messages move to a new terminal `failed` state instead of being delivered. cmux agent messages off|on|status [<target>] [--workspace] turns messages off for one surface (default: the caller's) or a whole workspace through a new agent.message.settings socket method. The command palette offers the same toggle for the focused terminal. All entrypoints share AgentMessageCenter.setReceivingEnabled; sends to an opted-out recipient fail naming the recipient, and its queued messages fail. Opt-outs are stored in the message journal, capped at 1,000 entries, and compacted with the messages. agent.message.settings is not on the remote relay allowlist.

Read isEnabled() once per locked operation.
failBlockedQueued currently performs one UserDefaults read per queued message while holding lock. Capture the setting once after acquiring the lock and pass it to blockLocked.
The current app closure does not re-enter AgentMessageStore, so a deadlock is not established for current callers. Do not read the setting before locking: that can use a stale value if the operation waits for lock.

Move backlog cleanup out of lazy store initialization.
AgentMessageCenter.store runs failBlockedQueued() before returning the static let. That method holds AgentMessageStore.lock while it scans the full message order and appends one failure record for each blocked queued message. ContentView.openAgentInbox() can access the store synchronously, so a large backlog can stall the UI. Create the store and run cleanup from an explicit startup lifecycle instead of performing this work on first access. Register the settings observer there as well.

Keep cold journal loading out of the command-palette snapshot path.
When this is the first agent-message access, commandPaletteContextSnapshot can call AgentMessageCenter.isReceivingDisabled, lazily construct AgentMessageCenter.store, and synchronously replay the journal with Data(contentsOf:). If this snapshot runs on the main actor, the first palette open can block on journal size.
Initialize the store before the interactive palette path, or move the cold journal load off the main actor.

Make --workspace without a target work outside a cmux surface.
The guard accepts scope == .workspace with only callerWorkspace set. The resolver also handles that case at Lines 120-122. In surface scope, a caller that has only workspace_id gets the missingSettingsTarget error. That outcome is correct.
In workspace scope with both IDs set, the resolver uses callerSurface and looks up the workspace with workspaceContainingPanel. Suppose the surface closed but CMUX_SURFACE_ID is still in the environment. The lookup returns nil, and the request returns not_found. The resolver does not fall back to callerWorkspace. The command then fails for a workspace that still exists.

Update the workspace-scope resolver so a stale callerSurface does not prevent
using callerWorkspace when the workspace still exists. Preserve
callerSurface-based lookup when it resolves a workspace, and keep surface scope
requiring a valid target.

Claim and the wake lease now check the off switches for each message under the same lock that delivers it, so a switch turned off between the old sweep and the claim fails the message instead of delivering it. The sweep skips messages on a live wake lease: the hook has already printed them, so the acknowledgement records them delivered. An expired lease leaves them to the next sweep. When the opt-out store is full, it drops an opt-out for a closed surface or workspace first, writes the drop to the journal so replay agrees, and logs it. The store is warmed off the main thread at launch. CLI help and docs explain workspace targets and the four message states. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Fix the String(format:) call that uses a localized format string without an %@ check.
String(localized:defaultValue:) takes a String.LocalizationValue. The format "Messages to %@ are off." is a plain literal in the default value. The catalog entry may reorder or omit %@ in a translation. String(format: format, label) then reads label as a C vararg. A String passed as CVarArg with %@ works in Foundation on macOS. The call can still crash if a translation uses a different specifier, such as %d. Interpolate label inside the localized string instead. This removes the runtime format step.

Remove the test hook from production source.
beforeDeliveryLockForTesting is a test-only member in a production Sources/ file. Its name matches the banned …ForTesting pattern. Production code never sets it, but claimQueued and deferredMessages call it on every delivery.
The property is also an unsynchronized var. Socket worker threads read it without holding lock, so a concurrent write is a data race.
The invariant under test is that the block decision happens under the same lock as the state transition. The isEnabled closure you inject can test this without a hook. In toggleBeforeClaimLockFails, make the closure return true on its first call and false afterwards. As an alternative, assert the behavior through blockLocked with @testable import.

…queued messages `cmux agent messages status` for a surface now also reports when its workspace has messages off, since such a surface receives nothing. The socket reply gains `workspace_receiving` for surface targets. A message can now only move to failed from queued, so one already shown to its agent can never be recorded as failed, including on replay.

Add translations for every supported locale.
Line 607545 adds cli.help.agentMessages with translations for only nine locales. The catalog also supports bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and `uk. The same gap affects other new agent-message labels, help text, and errors. Users of those locales will not see localized text for these strings. Add translations for every supported locale to each new entry.
As per coding guidelines, “additions include complete translations for all existing locale codes in the touched catalog.” As per path instructions, the full-internationalization rule requires complete translations for every supported locale.

Handle stale surface context in workspace scope.
When scope == "workspace" and callerSurface no longer resolves, the current branch returns not_found without trying callerWorkspace. The CLI forwards both inherited IDs, so this can reject a valid workspace request.
Do not add an unconditional workspace fallback. CMUX_WORKSPACE_ID can be stale after a surface moves. Use it only when its association with the caller is authoritative; otherwise require an explicit target or fail closed.

Lawrence asked to make sure agent communication can be disabled. This adds an off switch for
cmux agent messageat three levels.What changes
agentMessages.enabled(defaulttrue) in~/.config/cmux/cmux.jsonand Settings > Automation > Agent Messages. When it isfalse,cmux agent messagefails with "Agent messages are turned off (agentMessages.enabled is false).", nothing is stored, and every queued message moves to a newfailedstate with reasonmessages_disabled. Hooks stop receiving at once.cmux agent messages off|on|status [<target>], defaulting to the caller's surface. The target resolves the same way ascmux agent message, sooff <target>silences exactly the agent a send to it would reach. Sending to it fails with "Recipient surface:5 (title) has messages disabled." and nothing is queued. Messages already queued for it fail withrecipient_disabled. The command palette has "Turn Off/On Agent Messages for This Tab" for the focused terminal.cmux agent messages off --workspace [<target>]covers every surface in the workspace (workspace_disabled).agent.message.settings(read, or set withenabled).agent.message.sendreturns error codesmessages_disabled,recipient_disabledorworkspace_disabled.agent.message.list --state failedworks and the event bus publishesagent.message.failed. The Agent Inbox shows failed messages as "Not delivered" and a refused inbox reply shows the reason.docs/agent-messages.md,agentMessages.enabledindocs/configuration.md, schema, settings skill reference, CLI contract.Design choices
These are my choices; Lawrence owns the design and can change any of them.
AgentMessageStore.appendchecks the switch and opt-outs under its lock, so every entrypoint (socket send, Agent Inbox reply) is covered. CLI, socket and palette toggles all callAgentMessageCenter.setReceivingEnabled.claimand the wake lease check the switches for each message under the same lock that marks it delivered or puts it on a lease, and fail it there if it is blocked. A toggle that lands after a sweep but before the claim fails the message; tests turn the switch off at that point for both paths.pollsweeps before counting. The global switch is a UserDefaults read, so a toggle that lands after that read but in the same call still counts as after the delivery.delivered. If the lease expires unacknowledged, the next sweep or claim fails them.recipientrecords, so they survive restarts and compaction. Surface ids are stable across session restore only as far as panel ids are; an opt-out on a surface whose id changes is lost.agent.message.settingsis not on thecmux sshrelay allowlist. It changes local delivery for local objects and the remote flow does not need it. Deny is the default; a test asserts it.cmux config set agentMessages.enabled falseworks through the existing config command.AgentMessageStorepersistence moved toAgentMessageStore+Journal.swift(no behavior change) to stay inside the file length budget.CPU, memory and disk
UserDefaults.didChangeNotificationobserver reads one Bool and sweeps the store only on the on-to-off transition.Localization audit
New and changed strings: the settings card (title, on/off subtitles, note), the two command palette titles, "Not delivered", the three send errors, the CLI output lines and
cmux agent messages --help(including the paragraph on workspace targets without--workspace), the socket errors for scope, missing target and save failure, and the updatedcmux agent inbox --helpand state error (now listingfailed). Each has entries in en, de, fr, ar, es, zh-Hant, zh-Hans, ko and ja inResources/Localizable.xcstrings, and the card strings also in the CmuxSettingsUI catalog.

Adds an off switch for
cmux agent messageat three levels: globally via the newagentMessages.enabledsettings key (defaulttrue, also available under Settings > Automation), per agent, and per workspace. When a recipient's messages are off, sends fail with a clear reason, nothing is stored, and already-queued messages move to a new terminalfailedstate instead of being delivered.Behavior
agent.message.settingssocket method andcmux agent messages [on|off|status] [<target>] [--workspace]toggle messages for one surface (default: the caller's) or a whole workspace.agent.message.sendnow returnsmessages_disabled,recipient_disabled, orworkspace_disablederror codes; the Agent Inbox shows blocked messages as "Not delivered" with the reason.Design notes
failedstate is final; re-enabling messages does not resend refused messages, so senders learn about the refusal immediately.agent.message.settingsis not on thecmux sshrelay allowlist, so remote sessions cannot toggle messages.Written for commit 61a56c5. Summary will update on new commits.
