OpenFeature SDK Integration

What it does

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.

When to use it

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.

What's included

• Scripts: none bundled (has_scripts=false)
• References: external docs and spec links included in the skill body
• Instructions: step-by-step install commands per language, initialization examples, evaluation and context examples, hook patterns, and testing approaches. Also includes recommended best practices for naming flags, defaults, and error handling.

Compatible agents

Useful for developer-focused agents that can provide code snippets and run package manager commands (npm, go get) or suggest configuration changes in repos.
