Guides integration of the vendor-agnostic OpenFeature feature-flag SDK across languages: installation, provider setup, flag evaluation, hooks, and testing patte
This skill documents how to integrate OpenFeature, a vendor-agnostic feature flag SDK, into applications across Node.js, Python, Go, Java, and Rust. It explains the architecture (SDK API, providers, flag sources), installation steps for different runtimes, initialization patterns, evaluation contexts, hooks for logging/telemetry, and testing with in-memory providers or mocks. Practical code snippets show provider setup, flag evaluation, React integration, and common testing strategies.
Activate this skill when users ask about feature-flagging, A/B testing, canary releases, progressive rollouts, or when they mention OpenFeature, flagd, LaunchDarkly, or similar tooling. It’s appropriate for engineers implementing flagging, writing tests around flags, or troubleshooting flag evaluation behavior.
Useful for developer-focused agents that can provide code snippets and run package manager commands (npm, go get) or suggest configuration changes in repos.
OpenFeature SDK Integration skill providing vendor-agnostic feature flag guidance across 6 languages (TypeScript/Node, Python, Go, Java, Rust, React). Well-structured reference skill with clear trigger conditions, architecture diagrams, and practical examples including initialization, evaluation, hooks, and testing patterns. No bundled scripts — purely a reference skill. Clean SKILL.md with no security concerns.
Solid reference skill for OpenFeature. Good trigger table distinguishing from sibling skills. Could benefit from a references/ directory with language-specific examples and a scripts/ directory for validation. No security issues whatsoever — purely instructional content with no executable code.
