- Treat `UserAbortError` as a successful prompt cancellation - Make interrupted deploys exit with status 0 - Restore SIGINT listeners when the Clerk Bird game exits
- Exit interrupted operations via SIGINT with status 130 - Treat auth and timer waits as clean exits - Abort in-flight requests and flush interrupt telemetry
… as interrupted work
The wait/work split classified a timer as idle, but every sleep in the CLI is a step inside an operation. `clerk deploy status --wait` spends ~93s of a ~95s run asleep between polls, so Ctrl-C almost always landed in that window and exited 0 — which is exactly what that command's exit code means to a script: "the deploy is complete". In a non-TTY run, where clack is not there to absorb the interrupt, `clerk deploy status --wait && ./promote.sh` promoted a deploy the user had just interrupted, and it printed nothing on the way out. Narrow the clean exit to waiting on a human — browser sign-in and the $EDITOR round-trip — and rename the seam to `whileAwaitingUser` so the next poll loop does not reach for it. Everything else is work: requests, timers, poll intervals, the decorative shine, and the bookkeeping tail. Dropping `markCommandComplete` means Ctrl-C during the tail now exits 130 too. That is deliberate: a Ctrl-C is a Ctrl-C and the exit code says so. The cost is a ~2s window per successful command (1500ms update check plus ~450ms of animation) where interrupting halts a wrapping script even though the command itself finished. `deploy`'s resumable pause goes back to 130 for the same reason — a production instance exists but DNS or OAuth does not, so `clerk deploy && cutover` must stop either way. That removes the only zero-exit CliError, so the special cases it needed in `reportError` and `telemetryResultForError` go with it. Because `runProgram` returns early once an interrupt is latched, a thrown error's message never reaches the terminal on this path. `deploy` now prints its resume hint, and `deploy status` its partial report, as side effects from their own catch blocks. Also route `webhooks listen`'s drain through a shared `reportAndExitInterrupted`. It handles its own Ctrl-C so it can drain in-flight forwards, and it was exiting without telling telemetry anything — leaving the command most likely to actually receive a SIGINT as the one that never reported it.

This guard calls exitInterrupted without return, which is the exact pattern the new interrupts.md rule warns about ("Call it as return exitInterrupted(...) at call sites too"). Under a no-op process.exit stub, the same stub listen.test.ts installs, a second Ctrl-C falls through into beginInterrupt(), the raw-mode and cursor writes, and a second reportAndExitInterrupted, so telemetry flushes twice. The existing test only passes because its stub throws instead of no-op'ing.

The drain is a fire-and-forget void (async () => ...)() with no .catch. If anything in it rejects (the dynamic telemetry import inside reportAndExitInterrupted, or client?.stop() throwing), the rejection is unobserved and the process never reaches the signal-death exit this PR exists to guarantee. A .catch that falls back to exitInterrupted keeps the contract even on an unexpected error.

There was a problem hiding this comment.
AbortSignal.any([own, interruptSignal()]) registers an abort listener on the shared process-lifetime signal for every request that brings its own signal, and the listener is only released when the derived signal is garbage collected. webhooks/forward.ts passes AbortSignal.timeout(30_000) per delivery and deliveries run concurrently, so a burst can pile enough listeners on the shared signal to trip the default max-listeners warning. Raising the ceiling on the shared signal documents that it is intentionally observed by unbounded concurrent requests.
// in signals.ts
import { setMaxListeners } from "node:events";
let controller = new AbortController();
setMaxListeners(0, controller.signal);
export function _resetInterruptState(): void {
controller = new AbortController();
setMaxListeners(0, controller.signal);

There was a problem hiding this comment.
The comment says this emits "what the last completed poll established", but state here is the snapshot resolved before runWait started, and waitForDeployStatus never writes its polled status back into it. If DNS turned valid on the last poll before Ctrl-C, the report still shows the pre-wait pending status. Either thread the latest polled status out of the wait loop, or reword the comment to say the report reflects the pre-wait state.
let lastKnownStatus: DeployComponentStatus | undefined;
try {
outcome = await runWait(state, {
triggerCheck: !preflightTriggered,
onProgress: (status) => { lastKnownStatus = status; },
});
} catch (error) {
if (interruptedExitCode() === null) throw error;

? { ...state, snapshot: { ...state.snapshot, componentStatus: lastKnownStatus } }

emitReport(buildDeployStatusReport(partialState, null));

This exact ternary now appears verbatim in five files this PR edits (here, apps/create.ts, apps/list.ts, config/push.ts, users/list.ts). Since every call site was already open in the diff, a shared helper next to UserAbortError would keep the classification in one place.
// errors.ts
export function closeStatusForError(error: unknown): "paused" | "failed" {
return error instanceof UserAbortError ? "paused" : "failed";
}
// each call site
closeStatus = closeStatusForError(error);| // the moment an interrupt is latched — so nothing below would ever print. | ||

This catch calls isInsideGutter() three times and pausedOutro(pausedOperationNotice()) twice across three sequential ifs, which reads as three independent conditions when there are really two outcomes. Hoisting the gutter check and collapsing the duplicate paused call makes the branching visible.
} catch (error) {
const insideGutter = isInsideGutter();
if (interruptedExitCode() !== null) {
if (insideGutter) pausedOutro(pausedOperationNotice());
throw error;

if (error instanceof DeployPausedError) {

Summary
Ctrl-C now reports what the CLI was doing when it arrived. Interrupting anything in progress — an in-flight request, a poll interval or retry backoff, a project generator run by
clerk init, orclerk webhooks listenonce it has drained — exits 130, and the interrupted run is reported to telemetry instead of going unrecorded. Only waiting on a human is a clean exit: cancelling a prompt, abandoning browser sign-in, or quitting$EDITORall exit 0.The 130 is emitted by dying from the signal rather than calling
process.exit(130). Both make the shell print 130, but only a real signal death setsWIFSIGNALED, which is what a wrapping script inspects; withexit(130)a script keeps running after the user pressed Ctrl-C.A timer is deliberately not a human wait.
clerk deploy status --waitspends roughly 93 seconds of a 95-second run asleep between polls, so treating a sleep as idle meant Ctrl-C almost always exited 0 — which is exactly what that command's exit code means to a script, "the deploy is complete".clerk deployand its resumable pause report 130 for the same reason: a production instance exists but DNS or OAuth does not, soclerk deploy && ./cutover.shmust stop either way. BecauserunProgramhands rendering to the signal handler once an interrupt is latched, both commands now print their resume hint and partial status from their own catch blocks rather than through a thrown error's message.The bookkeeping tail is not a wait either. Interrupting the update check or the closing animation exits 130, which costs about two seconds per successful command where Ctrl-C halts a wrapping script even though the command itself finished. That is the intended trade: a Ctrl-C is a Ctrl-C, and the exit code says so.
