Claude Code logs it when it fails to spawn the background daemon: when spawning a transient daemon with `daemon run --origin transient` errors, when a configured agent launcher's daemon never becomes reachable, and when the daemon's upgrade self-respawn fails to spawn. Fields include `errno_enoent`, `errno_eacces`, `errno`, `launcher_configured`, `failed_stage` or `respawn` depending on the site.","description_source":"code","described_by":{"bundle":"2.1.241","author":"claude-opus-5-5"},"presence":{"first_seen":"2.1.138","removed_in":"2.1.242","in_current_build":false,"newest_mined":"2.1.308","builds":93,"mined_builds":149,"first_cited":null},"aliases":[],"entries":[],"entries_total":0,"docs":[],"docs_total":0,"gates":[],"related":[{"name":"tengu_bg_daemon_spawn_reinstall_wait","slug":"tengu-bg-daemon-spawn-reinstall-wait","description":"Starting the background helper during an npm reinstall now waits and retries instead of failing."}],"url":"https:\/\/changelogs.core-directive.com\/reference\/flag\/tengu-bg-daemon-spawn-failed","family_url":"https:\/\/changelogs.core-directive.com\/reference\/flag.json"}
