The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## English
### Purpose & Overview
Production-grade guidelines for feature flag management, progressive feature rollouts, canary deployments, A/B testing experiment analysis, and dynamic server-side/client-side feature evaluation using PostHog, LaunchDarkly, and GrowthBook.
### Key Capabilities
- **Feature Gating**: Decoupling code deployment from feature release with instant kill-switches.
- **Canary & Percentage Rollout**: Incrementally releasing new features to 5%, 25%, 50%, and 100% of user segments.
- **Experimentation Engine**: Statistical A/B testing with conversion metrics and variant analytics.
```typescript
import { PostHog } from 'posthog-node';
const posthog = new PostHog(process.env.POSTHOG_API_KEY!);
export async function isNewCheckoutEnabled(userId: string) {
const isEnabled = await posthog.isFeatureEnabled('new-checkout-flow', userId);
return isEnabled;
}
```
### Implementation Checklist
- [ ] Initialize the Feature Flag client (e.g., PostHog/LaunchDarkly) securely on the server and client.

How to install
mdr add roedyrustam/vibes-plug/feature-flag-analytics-expert@sha256:61a5d64b84b1305dThe line at the top of this page pins the label v4.2.1, 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.
