The new isInitialCall parameter lacks JSDoc documentation. Could we add documentation explaining its purpose?

Is this the right approach? The issue discussion indicates that the problem is subsequent calls timing out while waiting for initialization, not the initial call itself. This implementation removes the timeout for initial calls, but the actual bottleneck (git add during initialization) still has a hard-coded 5-second timeout in ShadowCheckpointService. Could we consider a more comprehensive solution?

await pWaitFor(() => {
console.log("[Task#getCheckpointService] waiting for service to initialize")
return !!task.checkpointService && !!task?.checkpointService?.isInitialized
}, waitOptions)
if (!task?.checkpointService) {
task.enableCheckpoints = false
return undefined

Good addition of the --ignore-errors flag! However, the 5-second timeout is a magic number. Consider defining it as a constant at the top of the file:

This would make it easier to adjust if needed.

})

This Promise.race() implementation could lead to incomplete staging. If the timeout wins, the staging operation continues in the background but we proceed with a potentially empty commit. This could miss important files. Consider:

  1. Cancelling the staging operation if timeout occurs
  2. Or waiting for staging to complete but with a longer, configurable timeout
  3. Or deferring staging until the first actual checkpoint (lazy staging)
