fix(relay-node): wake idle Cursor CLI sessions with Relay messages - #2121
A Relay message sent to an idle cursor-agent session (for example dog-pipe) was staged but never woke the session. It showed up only at the session's next tool call or prompt. Cursor editor chats were fixed earlier by a stop hook that waits after a completed turn, but CLI sessions still returned from that hook at once.
Change
The CLI stop hook waits. A Cursor CLI session's stop hook (cursor-hook --wait) now waits after a completed turn, like the editor's. It waits under the cursor-agent that holds the conversation's store.db (wait::Holder::Cli), and stops waiting once that process quits or switches to another conversation.
Follow-up turns are tracked. The CLI runs no beforeSubmitPrompt for a turn that a stop follow-up starts. Without a fix, the hook woke a session once and then never re-armed. A follow-up's stop (loop_count > 0) for a turn that is neither current nor earlier now names that turn current once the turn before it ended (wait::stop_seen, which the third commit below made one rule for the CLI and the editor).
No five-follow-up cap. The cap that was hard-coded for CLI sessions is gone, which matches the waiting entry's loop_limit: null.
Verification
Live testing used a real cursor-agent (2026.11.05-86047df) through the running Agent Relay Desktop core, with this branch's agent-relay-node cursor-hook entries added to ~/.cursor/hooks.json:
Three wakes in a row. A registered, idle CLI session was messaged three times in a row (KIWI, MANGO, LYCHEE). Each message was handed over 2 to 3 seconds after sending, and each reply came back over the relay. Before the follow-up fix, only the first wake worked.
A person types while the hook waits. The prompt runs at once, the old waiter retires, and a new one arms for the new turn.
Ctrl-C while the hook waits. The CLI exits in about 3 seconds, and the hook and its waiter file are cleaned up.
Headless mode.cursor-agent -p runs no hooks at all, so headless runs are never held open.
Tests.cargo test --locked passes for crates/relay-node (2,360 lib tests plus integration suites), and cargo fmt --check is clean. New unit tests cover a wake, a wake after a follow-up turn, a late older-turn stop, the agent quitting, and the agent switching conversation.
Known trade-off (same as the editor)
Cursor waits for every stop hook before it acts on any follow-up. While Agent Relay's hook is waiting, a followup_message returned by another user stop hook waits too, until a Relay message arrives or the wait ends after 59 minutes.
Second commit: Cursor editor chats reply and wake after Cursor-started turns
This was opened separately as #2122 and moved here because it touches the same turn tracking. It fixes three editor-side bugs.
Replies. Cloud's hosted MCP can't send as any Cursor chat, because Cursor's MCP calls don't say which chat they come from. A Cursor session that declared "mcp":"agent-relay-sessions" was still shown only that send tool, plus a line saying not to send any other way. relay_mcp_access now treats every Cursor session, editor and CLI, as socket-only. On macOS a Cursor editor conversation also gets the probe client (needs_probe_client), because Apple's curl hides CURSOR_CONVERSATION_ID and curl replies were refused as not_a_relay_session.
Editor turns Cursor starts itself. The editor runs no beforeSubmitPrompt for a turn it starts itself, such as the "background task finished" turn. So .turn kept naming the previous turn, and the waiting stop hook retired at once. Its stop now names that turn (wait::stop_seen, as revised in the third commit below), which corrects the note that "the editor names every turn as it starts".
A chat's first turn. A new chat couldn't put itself on the relay until Cursor wrote its transcript. editor_caller now claims a conversation for a tool that names it under a verified extension host. That was already possible by running cursor-hook from the same tool, and every other may_claim check still applies.
Evidence (editor conversation b72f559d):
.turn held two earlier turns after four turns. It would have held three if the 6:40 PM notification turn had run beforeSubmitPrompt.
A message sent while the chat was idle was only handed over at its next tool call.
Hosted send_relay_message failed with "cannot verify this chat's desktop identity", while agent-relay-probe send from the same chat delivered.
Validation on this branch:
cargo test for crates/relay-node passes: 2,363 lib tests plus all integration suites.
cargo check --locked --no-default-features --tests, scripts/check-open-source.sh and cargo fmt --check pass, and clippy reports nothing in the touched files.
Each new test fails when its fix is reverted. I re-ran this for the merged editor call site.
Residual risk. None from timing since the third commit, which removed the 2 s window.
Third commit: review fixes
This commit addresses the review threads on this PR and on #2122.
One clock-free rule for turns that run no beforeSubmitPrompt. Greptile found that a follow-up's late stop could replace a prompt submitted after it. CodeRabbit found that the editor's 2 s file-time window broke if the clock stepped back, and missed background turns that finished quickly. The fix:
followup_turn_seen and untracked_turn_seen are replaced by wait::stop_seen. Every proven stop marks its own turn as ended in <id>.turn.
A stop of a turn .turn doesn't know names that turn as current only once the current turn has ended, because Cursor starts a turn only after the previous one ended.
A prompt submitted in between hasn't ended, so it stays current.
Missing, unreadable or older .turn files still fail closed until the next prompt. .turn stays at version 1, and files without the flag read as not ended.
A second cursor-agent on the same conversation. Devin, Greptile and CodeRabbit all found that a waiting CLI hook kept claiming after another cursor-agent resumed its conversation. Before each claim, Waiting::shared now checks the same one-holder rule as hook_caller. If another holder exists, the hook ends Moved and the message stays pending.
Channel and Connect replies. Devin found that a Cursor editor chat on macOS was handed curl for channel replies, channel subscriptions and Relay Connect replies. These now use the probe, as its direct-message replies do.
Validation:
cargo test for crates/relay-node passes: 2,367 lib tests plus all integration suites.
The Cursor CLI's stop hook answered at once, so a cursor-agent idle at
its prompt kept a staged message until its next tool call or prompt.
It now waits after a completed turn like the editor's, under the
cursor-agent that holds the conversation, and stops once that process
quits or switches conversation. The CLI runs no beforeSubmitPrompt for
a stop follow-up's turn, so that turn's stop names it current, letting
the hook wait again after every wake. Cursor's five-follow-up cap no
longer applies to CLI sessions, matching the waiting entry's
loop_limit: null.

Cursor CLI stop hooks now share the waiting path used by editor sessions. Turn tracking and holder checks govern waiting. Eligible editor tools can establish conversation records before transcripts exist. Cursor CLI reply routing uses session sockets and probe-client handling.

Holder-aware waiting and turn tracking crates/relay-node/src/relay/cursor_cli/wait.rs, crates/relay-node/src/relay/cursor_cli/wait_tests.rs
The wait API accepts editor or CLI holders. Turn tracking records completed turns, and holder checks confirm continued ownership. Tests cover generation changes, unreadable turn files, and holder changes.

CLI stop hooks use the shared wait path for watched turns. Tests cover staged-message delivery, follow-up turns, late stops, agent exit, and conversation changes. Documentation and changelog entries describe the behavior.
Eligible editor tools can establish a conversation record before a transcript exists. Tests cover rejected claims and unreadable ancestor environments.

Merge Risk: Moderate · up to 84d94
Resolve stale-stop ordering before merging: an older hook can displace the current waiter and consume its message. Transient storage failures can also stop automatic wake-ups. Other stop hooks remain subject to the documented delay of up to 59 minutes.

The title "fix(relay-node): wake idle Cursor CLI sessions with Relay messages" matches the main change. The PR makes the Cursor CLI stop hook wait after a completed turn, so Relay messages wake idle sessions. It also tracks follow-up turns and removes the five-follow-up cap. The title omits the editor-side changes in the second commit, which is acceptable because the title does not need every detail.

Test the late stop while the CLI waiter is active.
Run the late gen-1 stop before sending m-2, then assert that gen-2 still answers. The current test joins gen-2 first, so it cannot detect cancellation of an active CLI waiter. The editor test covers the shared turn_seen exemption, but not the CLI-only followup_turn_seen path.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
followup_turn_seen treats an unknown generation as newer, although an older follow-up whose stop has not previously run is also unknown. It can therefore replace a newer user turn with an older generation. The eight-entry history also makes sufficiently old generations unknown again.
The late stop can retire gen-3's waiter and claim a Relay message for the older turn, defeating the documented protection against late stops.
This can occur when: A follow-up generation gen-2 runs without beforeSubmitPrompt; the person starts gen-3 before gen-2's delayed stop hook runs. That stop arrives with loop_count > 0.

Not changed: this is the known trade-off described in the PR description, and the editor wait has behaved the same way since it shipped. Cursor acts on a followup_message only after every stop hook returns, and a hook sees neither the other hooks' output nor any follow-up Cursor holds. So nothing in the payload or the waiter state shows that another hook produced one. Two Relay builds (--dev) keep separate entries and inboxes, so with direct delivery on in both, a wake from one waits until the other build's hook ends. Turning cursor_direct_delivery off in one build avoids that; coordinating waits across builds would be a separate change.
The reason will be displayed to describe this comment to others. Learn more.
@khaliqgant Thanks for the clarification. I was wrong to suggest that the payload or waiter state could identify another hook’s follow-up.
I understand that the delay is an accepted trade-off for this PR. Disabling cursor_direct_delivery in one build avoids the cross-build delay, though other stop hooks can still be delayed.
Would you like a follow-up issue for cross-build wait coordination?
…started turns
Replies: Cloud's hosted MCP refuses to send as any Cursor chat (Cursor's
MCP calls carry no native chat id, and Desktop's Cursor token makes the
call require one), yet a Cursor session that declared
"mcp":"agent-relay-sessions" was handed only the hosted send tool plus a
route line forbidding any other way. Cursor sessions are now always
socket-only, and a Cursor editor conversation on macOS gets the probe
client (Apple's curl hides CURSOR_CONVERSATION_ID, so curl replies were
refused as not_a_relay_session).
Wake: Cursor runs no beforeSubmitPrompt for a turn the editor starts
itself (the "background task finished" turn), so <id>.turn kept naming
the turn before and that turn's waiting stop hook retired at once,
leaving the idle chat unwakeable. A completed editor stop of a turn .turn
does not know now names it current (untracked_turn_seen), unless the
current turn was named less than 2s before the hook started (it may be
the newer turn) or .turn cannot be read. This sits beside this branch's
CLI follow-up rule (followup_turn_seen), whose "the editor names every
turn as it starts" note it corrects, and runs before the shared
Holder::Editor wait under --wait only.
First turn: a new editor conversation could not be claimed until Cursor
wrote its transcript, so "put yourself on the relay" failed in a chat's
first turn. A tool naming its conversation under a verified extension
host now claims it, as running `cursor-hook` from that tool already could.
Evidence: in conversation b72f559d the 6:40 PM notification turn wrote no
.turn entry (.turn held two earlier turns after four turns, where every
turn running beforeSubmitPrompt would have left three), and a message
sent while idle was only handed over at the next tool call; hosted
send_relay_message failed with "cannot verify this chat's desktop
identity" while `agent-relay-probe send` delivered.
Review: adversarial pass (trust boundary unchanged: tool env claims were
already possible via cursor-hook; naming only under a proven window caller
and the per-conversation lock; unreadable/missing/future-dated .turn fails
safe; the CLI and editor rules never both run, since one conversation has
one holder; residual race needs >2s hook start delay plus a new turn) and
contextual pass (keeps the CLI follow-up rule and Holder wait as they are;
no docs describe the old rules; changelog keeps both PRs' entries).
Validation on this branch: cargo test (relay-node, 2363 lib + all
integration tests), cargo check --locked --no-default-features --tests,
scripts/check-open-source.sh, cargo fmt --check, clippy clean on touched
files; each new assertion fails with its fix reverted, rechecked for the
merged editor call site.

…shared
Addresses review on #2121 and #2122.
Turn order (Greptile P1 on followup_turn_seen; CodeRabbit on the 2 s
mtime window, clock steps and fast background turns): a stop of a turn
<id>.turn does not know was taken as the newer turn by unknown id alone
(CLI) or by file times (editor). Both rules become one, stop_seen, with
no clock: every proven stop marks its turn ended in <id>.turn, and a stop
of an unknown turn names it current only once the current turn ended.
Cursor starts a turn only after the one before it ended, so that turn is
newer; a prompt submitted before the stop ran has not ended and is left
in place. Missing, unreadable or pre-upgrade .turn files still fail
closed until the next prompt.
Shared CLI conversations (Devin, Greptile, CodeRabbit): a waiting CLI
hook kept claiming after a second cursor-agent resumed the same
conversation. It now rechecks, as hook_caller does, that its agent is
the one holder before each claim, and ends Moved otherwise.
Channel and Connect replies (Devin on #2122): a Cursor editor chat on
macOS got curl for channel replies and subscriptions and Relay Connect
replies; they now use the probe like its direct-message replies.
Review: adversarial pass (naming only under a proven caller and the
per-conversation lock; a prompt between turn_seen and stop_seen is not
ended and is kept; a subagent's stop can no longer take a running
parent turn; the extra process scan runs only at claim time; .turn
stays version 1 and older files read as not ended) and contextual pass
(one rule for editor and CLI replaces two; docs, changelog and PR notes
updated; no stale references).
Validation: cargo test (relay-node, 2367 lib + all integration tests),
cargo check --locked --no-default-features --tests,
scripts/check-open-source.sh, cargo fmt --check, clippy clean on touched
code; nine mutations (each fix reverted) each fail their new test.

Review feedback from this PR and #2122 is addressed in 84d9454:
Fixed:
The CLI waiter now re-checks that its cursor-agent is the only holder before every claim.
Turn order now uses each turn's own stop instead of unknown turn ids or file times. This covers the late follow-up stop, the 2 s window, a clock step and fast background turns.
Cursor editor channel and Connect replies use the probe on macOS.
CodeRabbit nitpick:the_turn_a_cursor_cli_follow_up_starts_waits_for_the_next_message now runs the late stop while the newer turn's CLI waiter is active, then wakes that waiter.
Answered with reasons in their threads, unchanged: follow-ups from other stop hooks, the first-turn claim, and the failed .turn write.
Docstring-coverage check: not acted on. Every new or changed item here has a doc comment; the check counts by this crate's own conventions.
Validation: the full cargo test suite for relay-node (2,367 lib tests plus integration), the no-default-features check, the open-source check and fmt all pass. Reverting each fix makes its new test fail.

Add a channel-prompt test that exercises the macOS Cursor editor target rather
than passing the probe flag as a constant; verify the rendered reply command and
both join and unsubscribe commands use the expected editor-specific behavior,
while preserving the existing CLI assertions.
Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Adding CursorCli to the required-probe branch makes connect_reply_line return None when probe_session_command rejects a sender; it no longer falls back to the encoded curl command. The supplied tests show that a sender such as host's name is rejected by the probe, while the curl form encodes otherwise problematic sender text.
The Connect message has no reply hint, although a subsequent CLI turn could have used the curl reply command.
This can occur when: On macOS, a Cursor CLI target is classified as needing the probe while a Connect delivery names a sender the probe command rejects, such as host's name.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
The matching-stop branch discards a failed write_turn result and leaves the existing turn readable with ended: false. Unlike start_turn's failure path, this does not invalidate the state, so subsequent unnamed follow-up turns can remain permanently ineligible for promotion.
The follow-up stop returns without waiting or consuming staged messages, and automatic Relay wake-ups stop until another prompt establishes turn state.
This can occur when: Writing the ended state fails transiently, such as because the filesystem is full, while the previous turn file remains readable. The current stop subsequently delivers a message and Cursor starts a follow-up without beforeSubmitPrompt.

- Around line 2146-2151: Replace the direct `true` probe flag in the
`connect_reply_line` test with a macOS Connect delivery test that exercises
`poll_connects` probe detection for a Cursor target whose injector reports a
probe requirement. Assert that the injected hint uses `connect-send`, preserving
the real delivery path rather than supplying the probe result directly.

Prevent older stops from replacing newer waiters.
If an unrecorded CLI follow-up’s stop runs after a newer prompted turn begins waiting, stop_seen treats the older turn as current. The older hook retires the newer waiter and can claim its Relay message. Preserve turn ordering before allowing an unknown stop to take over.

Problem
A Relay message sent to an idle
cursor-agentsession (for exampledog-pipe) was staged but never woke the session. It showed up only at the session's next tool call or prompt. Cursor editor chats were fixed earlier by astophook that waits after a completed turn, but CLI sessions still returned from that hook at once.Change
stophook waits. A Cursor CLI session'sstophook (cursor-hook --wait) now waits after a completed turn, like the editor's. It waits under thecursor-agentthat holds the conversation'sstore.db(wait::Holder::Cli), and stops waiting once that process quits or switches to another conversation.beforeSubmitPromptfor a turn that astopfollow-up starts. Without a fix, the hook woke a session once and then never re-armed. A follow-up'sstop(loop_count > 0) for a turn that is neither current nor earlier now names that turn current once the turn before it ended (wait::stop_seen, which the third commit below made one rule for the CLI and the editor).loop_limit: null.Verification
Live testing used a real

New unit tests cover a wake, a wake after a follow-up turn, a late older-turnstop, the agent quitting, and the agent switching conversation.Known trade-off (same as the editor)
Cursor waits for every
stophook before it acts on any follow-up. While Agent Relay's hook is waiting, afollowup_messagereturned by another userstophook waits too, until a Relay message arrives or the wait ends after 59 minutes.Second commit: Cursor editor chats reply and wake after Cursor-started turns
This was opened separately as #2122 and moved here because it touches the same turn tracking. It fixes three editor-side bugs.
"mcp":"agent-relay-sessions"was still shown only that send tool, plus a line saying not to send any other way.relay_mcp_accessnow treats every Cursor session, editor and CLI, as socket-only. On macOS a Cursor editor conversation also gets the probe client (needs_probe_client), because Apple's curl hidesCURSOR_CONVERSATION_IDand curl replies were refused asnot_a_relay_session.beforeSubmitPromptfor a turn it starts itself, such as the "background task finished" turn. So.turnkept naming the previous turn, and the waitingstophook retired at once. Itsstopnow names that turn (wait::stop_seen, as revised in the third commit below), which corrects the note that "the editor names every turn as it starts".editor_callernow claims a conversation for a tool that names it under a verified extension host. That was already possible by runningcursor-hookfrom the same tool, and every othermay_claimcheck still applies.Evidence (editor conversation
