Which programming languages are supported by this skill?

This skill provides implementation patterns for OpenFeature in Node.js (Server and Browser/React), Python, Go, Java, and Rust.

What are OpenFeature Hooks used for?

Hooks are lifecycle extensions that allow you to automatically inject logic like logging, metrics collection, or error handling into every feature flag evaluation.

Can I use this with specific vendors like LaunchDarkly or Split?

Yes, OpenFeature acts as a standardized layer that works with many backend providers including LaunchDarkly, Split, flagd, and GO Feature Flag.

OpenFeature is an open standard for feature flagging that provides a vendor-agnostic API, allowing you to switch between different flag providers without changing your application code.

How does this skill help with testing feature flags?

It includes specific guidance on using In-Memory providers for integration tests and strategies for mocking the OpenFeature SDK in unit testing environments like Vitest.

Implements vendor-agnostic feature flags and progressive rollouts using the OpenFeature standard across multiple programming languages.

소개

The OpenFeature SDK Integration skill empowers developers to implement standardized feature flagging, A/B testing, and canary releases without vendor lock-in. It provides Claude with specific expertise to set up SDKs for Node.js, React, Python, Go, and Java, while configuring diverse providers such as flagd, LaunchDarkly, or GO Feature Flag. By using this skill, you can ensure best practices for feature management, including the use of evaluation contexts for targeting, lifecycle hooks for observability, and robust testing patterns using in-memory providers.
