flags

Implement feature flags in Next.js or SvelteKit code with the Flags SDK (flags npm package). Use when installing or configuring the SDK, declaring flags with flag(), wiring a provider adapter (@flags-sdk/vercel, Statsig, LaunchDarkly, PostHog, GrowthBook, Global Config, OpenFeature, Split, Flagsmith, Reflag, Optimizely, or custom), using identify, dedupe, or evaluate, keeping pages static with precompute, setting up Flags Explorer and the Vercel Toolbar, or encrypting flag values. Triggers: flags/next, flags/sveltekit, flags/react, @flags-sdk/, vercelAdapter, precompute. For planning a flag, for Vercel Flags rollouts, experiments, and the vercel flags CLI, or for other frameworks, use the vercel-flags skill.
