Diagnosing SDK health
When a user asks about PostHog SDK versions, outdated SDKs, or whether they should upgrade, use the pre-digested SDK Doctor report rather than reasoning about versions yourself. The backend applies smart-semver rules (grace periods, minor-count thresholds, age-based detection), traffic-percentage thresholds, and provides user-facing copy that matches the SDK Doctor UI exactly.
Available tools
