    You say

    Our users see old profile data right after saving changes. We use a Rails app with a Postgres primary and two replicas. Can you fix this stale read issue?

    Your agent does

    I have analyzed your ApplicationController and identified missing session-stickiness for writes. I updated the database configuration to use 'distributes_reads' with a 2-second primary fallback window and added a test case simulating replica lag to verify the fix.

    What you get

    Implement read-your-writes consistency for user profile updatesAdd replica-lag detection to prevent loading stale dashboard dataConfigure primary database fallback for critical checkout workflowsFix transient 404 errors occurring immediately after resource creation

    About this skill

    Repair stale reads when apps write to a primary database but immediately read from lagging replicas.

    This skill traces database routing, consistency boundaries, and failover behavior. It adds read-your-writes guarantees, lag-aware routing, bounded primary fallback, monotonic reads, and replica-focused tests.

    ✔ Prevent post-save stale screens ✔ Protect critical workflows ✔ Detect replica lag ✔ Verify failover and recovery

    Ideal for SaaS, APIs, dashboards, and distributed databases.
