posthog-feature-flag-diagnosis

What problem does it solve?

Diagnose and triage feature flag and experiment issues such as false or empty evaluations, flicker/flash-of-original-content, stale person or group properties, exposure attribution problems, and server-side or bootstrap latency that lead to incorrect behavior.

Core Features & Use Cases

• Structured diagnostic framework: Step-by-step questions to inspect flag definitions, rollout conditions, variants, and recent configuration changes.
• Evidence correlation: Guide to query and interpret recent $feature_flag_called events, evaluate identify/identify-timing effects, and detect property ingestion race conditions.
• Experiment and latency analysis: Checks for exposure deduplication, server-side evaluation latency, bootstrap timing, and searching docs and GitHub for known bugs to produce remediation guidance.

Quick Start

Run the feature flag diagnosis for the flag key my_flag and user distinct_id 123 to produce a confidence-graded root cause report with evidence and actionable fixes.
