Guide for feature flags and A/B tests with the Flags SDK (`flags` npm package) and Vercel Flags. Use when: declaring flags with `flag()`, using `vercelAdapter()` or `vercel flags` CLI (add, list, enable, disable, inspect, archive, rm, sdk-keys), setting up providers/adapters (Vercel, Statsig, LaunchDarkly, PostHog, GrowthBook, Hypertune, Edge Config, OpenFeature, Split, Flagsmith, Reflag, Optimizely, or custom adapters), implementing precompute patterns for static pages, setting up `identify`/`dedupe`, integrating Flags Explorer/Toolbar, working with flags in Next.js (App Router, Pages Router, Middleware) or SvelteKit, writing custom adapters, or encrypting/decrypting flag values. Triggers: feature flags, A/B testing, experimentation, flags SDK, flag adapters, precompute, Flags Explorer, feature gates, flag overrides, Vercel Flags, vercel flags CLI, vercel flags add, vercel flags list, vercel flags enable, vercel flags disable, `flags/next`, `flags/sveltekit`, `flags/react`, `@flags-sdk/*`.

First infer which artist and release the user means, then find or create the RELEASE.md. Use this skill to create, update, or pull data from release documents, and to generate deliverables like DSP pitches, press one-sheets, and production specs.

Trigger when the user asks to write/rewrite for management / exec / VP / director / PM / release manager, asks for an "executive summary / leadership update / status update", says "make this less technical / less jargony", or asks for a slack / email / standup / meeting version of work originally written engineer-to-engineer.
