    Repair OAuth Refresh Races

    Example session with this skill installed

    My background workers keep hitting invalid_grant errors when they all try to refresh the same Google OAuth token at once. Fix the race condition.

    • Read your context and instructions
    • Compiled the repair oauth refresh

    I have implemented a single-flight refresh mechanism using a Redis lock. Added versioned token updates to the database to prevent stale overwrites. Verified the fix with a new concurrency test suite simulating 10 simultaneous refresh attempts.

    Eliminate invalid_grant errors during concurrent API callsImplement atomic token rotation and persistence logicAdd single-flight coordination to OAuth refresh flowsPrevent stale refresh tokens from overwriting newer credentials

    About this skill

    Repair apps where concurrent OAuth refreshes invalidate credentials, overwrite newer tokens, or force users to reconnect.

    This skill traces token expiry, rotation, storage, retries, and multi-instance races. It adds single-flight refresh, atomic token replacement, version checks, safe recovery, and concurrency tests.

    ✔ Stop duplicate refresh requests ✔ Preserve rotated tokens ✔ Prevent stale overwrites ✔ Avoid reconnect loops

    Ideal for SaaS integrations, APIs, and background sync.
