Function

progress

Send a bidirectional notifications/progress notification

Progress notifications inform the recipient about the status of long-running operations. They include:

  • token: Identifies which operation this progress is for
  • progress: Current progress value
  • total: Optional total value (for percentage calculation)
  • message: Optional human-readable status message

Progress notifications are advisory - recipients may ignore them without affecting operation correctness.
