Unclear It is not clear whether these memory figures are sent every time or only in some modes.

What

Claude Code can run as an MCP server, so other programs can use its tools. The results of those tools now carry extra details:

  • Memory: daemon_rss_mib, daemon_anon_mib and daemon_peak_rss_mib, which measure how much memory Claude Code's background process uses.
  • Tuning: jit_policy, collection_timer_off and start_tuning.

The count of programs left running now includes sessions being followed.

The status report for that background process no longer includes the supervisor version or uptime, controlSock, serviceInstalled or configuredWorkers.

Why

Memory figures for the background process now come with tool results, while some fields that status checks may have relied on are gone.
