Claude Code now reads a new response header, `x-ccr-tool-container-stops-soon`, but only from hosts that are already winding down. A container that sends it is marked as stopping soon, and one that stops sending it is unmarked. Before, only the winding-down header was tracked.\n\n**Why**\n\nClaude Code gets advance warning that a tool container is about to stop.\n\n- Area: Cloud Sessions\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
