As a Claude Code plugin

/plugin marketplace add anthropics/claude-plugins-official /plugin install vercel-plugin@vercel

This skill is part of the plugin “vercel-plugin”. In Claude Code the plugin installs it together with the plugin’s other skills, commands and hooks.

What does the flags-sdk skill do?

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, and others), using `identify`, `dedupe`, or `evaluate`, keeping pages static with precompute, setting up Flags Explorer, or encrypting flag values. For planning a flag, Vercel Flags rollouts and experiments, the `vercel flags` CLI, or other frameworks, use the `vercel-flags` skill.
