These side requests now include a `traceparent` header when one is available. `traceparent` is a standard header that labels a request so that tracing tools can follow it across several services.\n\n**Why**\n\nThis lets tracing tools connect Claude Code's side requests to the rest of the work they belong to.\n\n- Area: Telemetry\n- Names: `traceparent`\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: org\n- Heads-up: no"}
