 * `CLAUDE_ASYNC_AGENT_STALL_TIMEOUT_MS`: stall watchdog for subagents launched with `run_in_background`. Default `600000`. Resets on each stream event; on stall it aborts the subagent, marks the task failed, and surfaces the error to the parent with any partial result. Does not apply to synchronous subagents.
 * `CLAUDE_ENABLE_STREAM_WATCHDOG` with `CLAUDE_STREAM_IDLE_TIMEOUT_MS`: aborts the request when headers have arrived but the response body stops streaming. The watchdog is on by default for all providers; set `CLAUDE_ENABLE_STREAM_WATCHDOG=0` to disable it. `CLAUDE_STREAM_IDLE_TIMEOUT_MS` defaults to `300000` and is clamped to that minimum. After the abort, [Automatic retries](/docs/en/errors#automatic-retries) covers what Claude Code does, based on how far the response had progressed.

+`force` is a last-resort overwrite that discards a newer version another session published. On a conflict, the failed publish returns the newer content; Claude merges its changes onto that content, or re-reads the artifact, and publishes again. Pass `force` only when the user explicitly asks to discard that version.
 
 Pass `"list"` to enumerate the user's published artifacts; only `limit` and `scope` may accompany it. `scope` defaults to `"mine"`, which lists artifacts the user owns; `"shared"` lists artifacts other people shared with the user, and `"all"` lists both.

 Nothing is emitted at startup. Reset to an empty set whenever the session's CLI process starts or restarts and let the next membership change repopulate it.
 
+When you send a repeated `initialize` control request to a running session, such as with [`reinitialize()`](#query-object) after a transport gap, Claude Code follows the response with a snapshot of the current live set, even when it is empty. A reconnecting host therefore learns what is running without waiting for the next membership change. Before Agent SDK v0.3.239, Claude Code sent no snapshot after a repeated `initialize`.
