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()`, reading a connected same-team project's flags through Project Connections (`createVercelAdapter({ projectId })`), 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.

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
