# GO Feature Flag

Open-source feature flag solution with file-based configuration and OpenFeature integration. Use when setting up self-hosted feature flags, configuring flag files, or deploying the relay proxy.

## When to Use

**Automatic activation triggers:**
- User mentions "GO Feature Flag", "GOFF", or "gofeatureflag"
- Project has `@openfeature/go-feature-flag-provider` dependency
- Project has `flags.goff.yaml` or similar flag configuration
- User asks about self-hosted feature flags
- Docker/K8s configuration includes `gofeatureflag/go-feature-flag` image

**Related skills:**
- `openfeature` - OpenFeature SDK usage patterns
- `container-development` - Docker/K8s deployment
