What

When Claude Code sends session events to Anthropic's session service, it now flags a rejection as too large in two cases. One is a 413 error. The other is a 400 error whose message shows the size was the problem. Before, a 400 was treated as a general error.

Why

Remote sessions can handle oversized events on their own terms instead of treating them as a general failure.

The writer flagged doubtWhat remote sessions do after an event is flagged as too large, and whether it is retried, is not clear.
