Store and manage unstructured data with Azure Blob Storage. Create containers, upload and organize blobs, configure access tiers (Hot, Cool, Archive) for cost optimization, generate SAS tokens for secure temporary access, and set lifecycle management policies.

> protobuf

You are an expert in Protocol Buffers (protobuf), Google's language-neutral binary serialization format. You help developers define data schemas with `.proto` files, generate typed code for multiple languages, build efficient APIs with gRPC, and handle schema evolution with backward/forward compatibility — achieving 3-10x smaller payloads and 20-100x faster serialization than JSON.

> netlify-deploy

Deploy web projects to Netlify using the Netlify CLI (`npx netlify`). Use when the user asks to deploy, host, publish, or link a site/repo on Netlify, including preview and production deploys.

> recoil

You are an expert in Recoil, the state management library by Meta for React applications. You help developers manage application state with atoms (shared state units), selectors (derived/async state), and atom families — providing a graph-based state model that integrates naturally with React's concurrent features, avoids unnecessary re-renders, and handles async data fetching as first-class state.

> agent-memory

Add persistent memory to AI coding agents — file-based, vector, and semantic search memory systems that survive between sessions. Use when a user asks to "remember this", "add memory to my agent", "persist context between sessions", "build a knowledge base for my agent", "set up agent memory", or "make my AI remember things". Covers file-based memory (MEMORY.md), SQLite with embeddings, vector databases (ChromaDB, Pinecone), semantic search, memory consolidation, and automatic context injection.

> electric-sql

Build local-first applications with ElectricSQL — sync Postgres data to client devices in real-time.

Covers shape-based sync, real-time subscriptions, offline support, and conflict resolution.

> inngest

You are an expert in Inngest, the event-driven durable workflow engine for TypeScript. You help developers build reliable multi-step workflows, scheduled jobs, and event-driven functions with automatic retries, step-level caching, fan-out/fan-in patterns, rate limiting, and debouncing — running on any serverless platform (Vercel, Netlify, AWS Lambda, Cloudflare) with zero infrastructure to manage.

> logstash

Configure Logstash for log ingestion, parsing, transformation, and output to Elasticsearch and other destinations. Use when a user needs to build log processing pipelines, write Grok patterns, parse unstructured logs, enrich events, or set up multi-pipeline Logstash deployments.

> langchain

Build LLM-powered applications with LangChain. Use when a user asks to create AI chains, build RAG pipelines, implement agents with tools, set up document loaders, create vector stores, build conversational AI, implement prompt templates, chain LLM calls, add memory to chatbots, or orchestrate language model workflows. Covers LangChain v0.3+ with LCEL (LangChain Expression Language), structured output, tool calling, retrieval, and production deployment patterns.

> ember

You are an expert in Ember.js, the opinionated frontend framework for ambitious web applications. You help developers build large-scale SPAs with Ember's convention-over-configuration approach, Glimmer components, tracked properties, Ember Data for data management, routing with nested layouts, services for shared state, and ember-cli for scaffolding — providing Rails-like productivity for frontend development.
