    You say

    The user profile updates on the server but the header still shows the old name until a hard refresh. Check the cache keys and invalidation logic in the web and api directories.

    Your agent does

    I found a drift: the API uses 'user:v1:{id}' while the web client uses 'u_{id}'. I have prepared a patch to unify the key builder and added a Vitest suite using a mock cache to verify that mutations now trigger correct invalidation.

    What you get

    Unify cache key generation across server and client layersFix stale-while-revalidate logic and TTL mismatchesAdd deterministic tests for cache invalidation flowsIdentify missing tenant or account scopes in cache keysAlign CDN headers with internal application cache policies

    About this skill

    Repair cache invalidation drift in a repository using Cursor. This skill compares cache keys, namespaces, tags, TTLs, write paths, mutation hooks, server rendering, client caches, CDN headers, refresh jobs, mocks, tests, docs, and runbooks; detects stale reads, broad eviction, stampedes, tenant leakage, hydration mismatches, and unit drift; then prepares bounded patches and deterministic local tests without connecting to production caches, purging live keys, or changing deployed infrastructure.
