Under the hood
New internal schema describes how a self-hosted runner's session ended, with phase, exit code, and signal
What
Claude Code now has an internal schema for describing how a self-hosted runner's session process ended. It records a phase, either setup (the process never started) or run (it exited), plus optional exit_code and signal values.
Why
This gives more structured information about how and why a self-hosted runner session terminated, which should help in diagnosing failures that happen before versus after the session actually starts running.
