Function trackCommandFailure

packages/cli/src/telemetry/events.ts:345–354

(command: string, err: unknown)

// command failures are diagnosable. Enqueues synchronously — the process `exit`
// handler flushes it. Drop this into any command's failure path.
export function trackCommandFailure(command: string, err: unknown): void {
  const error = err instanceof Error ? err : new Error(String(err));
  trackCliError({
    error_name: error.name,
    error_message: error.message,

// Whisper being absent/uninstallable is an environment prerequisite gap, not a
// command crash — track it on its own low-severity metric instead of cli_error
