Workflow agents report a lost reply when the response goes silent

When a workflow agent's response stream goes silent, Claude Code now reports a lost reply, retries, and gives a specific error if all tries fail

What

A workflow agent is a helper agent that Claude Code runs as one step of a workflow. When the stream carrying its reply goes silent and Claude Code gives up waiting, the agent now:

  • treats it as a stall and stops that attempt
  • reports reply lost - the response stream went silent and Claude Code gave up waiting for it instead of the generic message that it stalled with no progress
  • marks the result as a lost reply and retries
  • if every attempt loses its reply, fails with an error saying the agent lost its reply on all attempts, instead of the generic abandoned error

The point at which a stalled attempt is retried is also capped, rather than always being half the stall time.

Why

If you run workflows, a failure now tells you the reply was lost to a silent stream, and a stuck step is retried sooner.
