Fix Authentication Race Condition
Claude CodeClaude Code debugs and fixes a token refresh race condition using sub-agent exploration and coordinated fix.
User reports intermittent auth token refresh failures in production.
Main agent plans the debugging approach and spawns 3 exploration workers in parallel.
Sub-agent reads auth-related files to understand token refresh flow.
Sub-agent checks existing test coverage for auth module.
Sub-agent searches git history and error logs for related issues.
Main agent synthesizes all sub-agent findings, identifies root cause, and chooses fix strategy.
Apply mutex lock to prevent concurrent token refresh calls.
Add test for concurrent refresh scenario.
Execute full test suite to verify fix doesn't break anything.
User reviews the fix and test before committing.
