Comprehensive guide for implementing feature flags and A/B tests using the Flags SDK (the `flags` npm package) and Vercel Flags (Vercel's feature flags platform, managed via dashboard or `vercel flags` CLI). Use when: (1) Creating or declaring feature flags with `flag()`, (2) Using Vercel Flags with `vercelAdapter()` or the `vercel flags` CLI (`add`, `list`, `enable`, `disable`, `inspect`, `archive`, `rm`, `sdk-keys`), (3) Setting up feature flag providers/adapters (Vercel, Statsig, LaunchDarkly, PostHog, GrowthBook, Hypertune, Edge Config, OpenFeature, Flagsmith, Reflag, Split, Optimizely, or custom adapters), (4) Implementing precompute patterns for static pages with feature flags, (5) Setting up evaluation context with `identify` and `dedupe`, (6) Integrating the Flags Explorer / Vercel Toolbar, (7) Working with feature flags in Next.js (App Router, Pages Router, Middleware) or SvelteKit, (8) Writing custom adapters, (9) Encrypting/decrypting flag values for the toolbar, (10) Any task involving the `flags`
Query Microsoft 365 Copilot for workplace intelligence - emails, meetings, documents, Teams messages, and people information. USE THIS SKILL for ANY workplace-related question where the answer likely exists in Microsoft 365 data. This includes questions about what someone said, shared, or communicated; meetings, emails, messages, or documents; priorities, decisions, or context from colleagues; organizational knowledge; project status; team activities; or any information that would be in Outlook, Teams, SharePoint, OneDrive, or Calendar.
