What
- Claude Code can now attach a "thread state" (how long since the last human message, and how many replies have happened since then) to queued messages in Projects threads, via a
stampThreadStateflag.- Cron-scheduled prompts that fire on a non-peer session now carry
stampThreadState: true, and athread_stateattachment can be pushed onto the message list during prompt processing. - Incoming user messages in genuine (non-overview) Projects threads get the same
stampThreadStateflag added when building the queued prompt. - Replies composed to artifact comment threads (for example via MCP) can also be stamped with thread state, gated behind a dedicated flag.
"thread_state"was added as a recognized category/content-block type alongside existing ones like"prefix_delta","deferred_tools_delta", and"diagnostics", with thestampThreadStateflag threaded through the relevant message-construction and result-merging functions.

Why
Tagging messages with thread state lets Claude Code, and anything consuming its output such as automated replies, know how stale or active a conversation thread is, which is useful context for deciding how to respond in scheduled or automated flows.
