What

Claude Code's usage data (anonymous reports about how features are used) now includes these events:

  • cli_projects
  • cli_purge_project_dry_run
  • session_transcript_write
  • subagent_tool_resolution

Events about creating trusted cloud repositories now also record what they cover. When a control request fails, the failure can now carry an error code. A control request is an instruction a host app sends to Claude Code. The report Claude Code makes when a feature goes wrong can no longer cause an error of its own.

Why

The new event names hint at a projects command and a trial-run mode for purging a project.
