What

If connections through the agent proxy fail while a command runs, Claude Code now appends a summary of them to the output, grouped by host and failure kind, with a curl URL for the full detail. It only appears when a proxy status URL is configured.

Details

  • Also emits a telemetry event tengu_agent_proxy_failure_note carrying the failure count and the most recent kind.
