posthog-feature-flag-diagnosis

Diagnose false or empty feature flag evaluations by analyzing flag definitions, rollout conditions, and recent configuration changes. The tool correlates evaluation evidence and recent $feature_flag_called events to identify property ingestion races and produce a confidence-graded root cause assessment.

Feature flag flicker or flash-of-original-content often stems from server-side evaluation latency or bootstrap timing issues. The diagnostic tool inspects bootstrap configurations, evaluates identify timing effects, and checks exposure deduplication to generate actionable remediation steps.

Troubleshoot stale person or group properties by querying recent $feature_flag_called events and evaluating identify timing guidance. The tool detects property ingestion race conditions and correlates them with flag definitions to explain evaluation failures.

Find known bugs causing feature flag misconfigurations by searching PostHog documentation and GitHub issues for related errors. The tool correlates these findings with your specific flag key and distinct_id evaluation evidence to deliver targeted remediation guidance.

Yes, the tool applies to both PostHog frontend and server-side SDK scenarios to analyze evaluation evidence. It identifies timing issues, bootstrap problems, and exposure deduplication across both environments to produce a confidence-graded root cause report.

Common limitations and edge cases for failing feature flags include property ingestion races, identify timing delays, and exposure deduplication conflicts. The tool inspects these constraints alongside recent configuration changes to isolate the root cause.
