Concurrent sub-agents trigger “Not logged in” errors when ~/.claude/.credentials.json is absent (valid token, macOS Keychain)
증상
When multiple Claude Code sub-agents run concurrently on macOS, all agents intermittently receive “Not logged in” errors even though the OAuth token is valid and was issued less than an hour ago. The session recovers on its own within 1-2 minutes without any user action (re-login is not required).
원인
Authentication credential mismatch, expiry, or permission scope gap between the requesting agent and the target API.
해결법
Creating a stub credentials file eliminates the catch branch:
echo '{}' > ~/.claude/.credentials.json
With the file present and mtime stable, kA9() becomes a no-op, hA retains its cached valid token, and the lock cascade cannot occur.
Verified this does not affect the 8-hour automatic token refresh: vB(expiresAt) returns true for both “about to expire” and “already expired” states, so _P1() still refreshes correctly when needed.
