PostHog feature flags, rollouts, A/B testing. Use when implementing gradual rollouts, A/B tests, kill switches, remote configuration, beta features, or user targeting with PostHog.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Feature Flags with PostHog > **Quick Guide:** Use PostHog feature flags for gradual rollouts, A/B testing, and remote configuration. Client-side: `useFeatureFlagEnabled` hook. Server-side: `posthog-node` with local evaluation. Always pair `useFeatureFlagPayload` with `useFeatureFlagEnabled` for experiments. Handle the `undefined` loading state on every flag check. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST always pair `useFeatureFlagPayload` with `useFeatureFlagEnabled` or `useFeatureFlagVariantKey` for experiments - payload hooks don't send exposure events)** **(You MUST use the feature flags secure API key (phs\_\*) for server-side local evaluation - personal API keys are deprecated for this use)** **(You MUST handle the `undefined` state when flags are loading - never assume a flag is immediately available)** **(You MUST include flag owner and expiry date in flag metadata - flags without owners become orphaned debt)** **(You MUST wrap flag usage in a single function when used in multiple places - prevents orphaned flag code on cleanup)** </critical_requirements> --- …

How to install
mdr add agents-inc/skills/api-flags-posthog-flags@sha256:16ec1cd30cbdb489The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
