Under the hood
Workflow and task execution can now report when they're waiting on an API rate limit
What
Workflow and task execution now accept an onRateLimitWait callback, connected to sink.onRateLimitWait. A new telemetry event, workflow_rate_limit_wait, is also recorded.
Why
This lets Claude Code track and surface moments when a workflow or task is stalled waiting on a rate limit, rather than that wait going unreported.
