Unclear None of these event names are tied to any described user-facing feature yet.

What

Several new event identifiers were added to Claude Code's internal telemetry event list:

  • mermaid_render
  • query_tool_detach
  • bridge_cancel_queued_message
  • device_mcp_host_consent
  • ccr_dir_sync_attach
  • usage_limit_grace_wrapup_subagent
Why

These are just event names added to internal tracking, so no user-facing behavior is confirmed yet, but they hint at work in progress around rendering diagrams, detaching a query tool, canceling queued bridge messages, MCP host consent on devices, directory-sync attachment, and a grace period around usage limits involving subagents.
