Securely manages API credentials for multiple providers (Anthropic Claude, Google Gemini, GitHub). Use when skills need to access stored API keys for external service invocations.
Use when implementing authentication with Better Auth in a TypeScript/Next.js app (session strategy, providers, cookies, CSRF, redirects, middleware, and security best practices).
Implement LangChain rate limiting and backoff strategies. Use when handling API quotas, implementing retry logic, or optimizing request throughput for LLM providers. Trigger with phrases like "langchain rate limit", "langchain throttling", "langchain backoff", "langchain retry", "API quota".
Comprehensive guide for implementing feature flags and A/B tests using the Flags SDK (the `flags` npm package). Use when: (1) Creating or declaring feature flags with `flag()`, (2) Setting up feature flag providers/adapters (Vercel, Statsig, LaunchDarkly, PostHog, GrowthBook, Hypertune, Edge Config, OpenFeature, Flagsmith, Reflag, Split, Optimizely, or custom adapters), (3) Implementing precompute patterns for static pages with feature flags, (4) Setting up evaluation context with `identify` and `dedupe`, (5) Integrating the Flags Explorer / Vercel Toolbar, (6) Working with feature flags in Next.js (App Router, Pages Router, Middleware) or SvelteKit, (7) Writing custom adapters, (8) Encrypting/decrypting flag values for the toolbar, (9) Any task involving the `flags`, `flags/next`, `flags/sveltekit`, `flags/react`, or `@flags-sdk/*` packages. Triggers on: feature flags, A/B testing, experimentation, flags SDK, flag adapters, precompute flags, Flags Explorer, feature gates, flag overrides.
Generate a production-grade React MQTT context for CloudSignal real-time notifications over WebSocket. Supports Clerk, Supabase, Auth0, Firebase, and custom OIDC auth providers. Use when implementing real-time notifications, live updates, job progress tracking, or WebSocket messaging with CloudSignal.
Implement VoIP calling with CallKit and PushKit. Use when building incoming/outgoing call flows, registering for VoIP push notifications, configuring CXProvider and CXCallController, handling call actions, coordinating audio sessions, or creating Call Directory extensions for caller ID and call blocking.
Call Ethereum and EVM chains from IC canisters via the EVM RPC canister. Covers JSON-RPC calls, multi-provider consensus, ERC-20 reads, and sending pre-signed transactions. Use when calling Ethereum, Arbitrum, Base, Optimism, or any EVM chain from a canister. Do NOT use for generic HTTPS calls to non-EVM APIs — use https-outcalls instead.
This skill should be used when the user asks to "set up authentication", "add login", "add logout", "configure Entra ID", "set up Azure AD auth", "add Microsoft login", "enable authentication", "set up sign in", "add role-based access", "add authorization", "protect routes", "add auth to my site", "configure identity provider", or wants to set up authentication (login/logout via Microsoft Entra ID) and role-based authorization for their Power Pages code site.
Extract people who engage (comment, react, repost) on any LinkedIn post, enrich their emails and company data, and upload to an Extruct people table for outreach. Supports multiple LinkedIn scraping providers (Anysite MCP, RapidAPI, Apify, Phantombuster, etc.). Triggers on: "post engagers", "linkedin engagers", "who commented on", "who liked", "who reacted", "linkedin post engagers", "scrape post", "extract engagers", "post commenters".
ALWAYS use when working with Angular Dependency Injection, providers, services, inject tokens, or hierarchical injection in Angular applications.
Instrument an existing codebase with LaunchDarkly AI Config tracking. Walks the four-tier ladder (managed runner → provider package → custom extractor + trackMetricsOf → raw manual) and picks the lowest-ceremony option that still captures duration, tokens, and success/error.
Emulated Microsoft Entra ID (Azure AD) OAuth 2.0 / OpenID Connect for local development and testing. Use when the user needs to test Microsoft sign-in locally, emulate Entra ID OIDC discovery, handle Microsoft token exchange, configure Azure AD OAuth clients, work with Microsoft Graph /me, or test PKCE/client credentials flows without hitting real Microsoft APIs. Triggers include "Microsoft OAuth", "Entra ID", "Azure AD", "emulate Microsoft", "mock Microsoft login", "test Microsoft sign-in", "Microsoft OIDC", "local Microsoft auth", or any task requiring a local Microsoft OAuth/OIDC provider.
