> atuin

You are an expert in Atuin, the Rust-based shell history tool that replaces your shell's built-in history with a searchable, syncable, context-aware database. You help developers set up fuzzy search across shell history, sync history across machines, filter by directory/host/session, and analyze command usage — turning shell history from a flat text file into a powerful productivity tool.

> clickhouse

ClickHouse is a columnar OLAP database built for real-time analytical queries over massive datasets. It supports a familiar SQL interface with powerful aggregation functions, materialized views for pre-computed rollups, and high-throughput inserts that make it ideal for event tracking, time-series analytics, and ad-hoc exploration of billions of rows.

> cache-strategy

Design and implement caching layers for APIs and web applications using Redis or Memcached. Use when you need to reduce database load, improve response times, or handle traffic spikes. Covers cache-aside, write-through, and write-behind patterns, TTL strategies, cache invalidation, and stampede prevention. Trigger words: cache, Redis, Memcached, TTL, cache invalidation, response time, throughput, rate limiting.

> drizzle-orm

You are an expert in Drizzle ORM, the lightweight TypeScript ORM that maps directly to SQL. You help developers write type-safe database queries that look like SQL (not a new query language), generate migrations from schema changes, and deploy to serverless environments with zero overhead — supporting Postgres, MySQL, SQLite, Turso, Neon, PlanetScale, and Cloudflare D1.

> drizzle-studio

Explore and manage databases with Drizzle Studio. Use when a user asks to browse database contents visually, inspect tables and data, run ad-hoc queries, manage database records through a GUI, debug database issues, or use a lightweight alternative to pgAdmin or DBeaver. Covers setup with Drizzle ORM, standalone usage, data browsing, filtering, and inline editing.

Build cloud backend applications with Encore — type-safe backend framework with built-in infrastructure. Use when someone asks to "build a backend", "Encore", "type-safe API framework", "backend with built-in infra", "auto-provision cloud resources", or "backend framework with databases built-in". Covers API definition, databases, pub/sub, cron, and auto-provisioned infrastructure.

> hasura

Expert guidance for Hasura, the GraphQL engine that gives the agent instant, real-time GraphQL APIs over PostgreSQL (and other databases). Helps developers set up Hasura, configure permissions, write custom business logic with Actions and Event Triggers, and optimize GraphQL queries for production.

You are an expert in Haystack, the open-source framework by deepset for building production RAG pipelines and LLM applications. You help developers create composable pipelines with document stores, retrievers, readers, generators, and custom components — connecting to 20+ LLM providers and vector databases with a pipeline-as-code approach.

> metabase

Metabase is an open-source business intelligence tool for creating dashboards and visualizations. Learn Docker deployment, database connections, creating questions and dashboards, embedding analytics, and API usage.

> mysql

MySQL is the world's most popular open-source relational database management system. Learn installation, SQL queries, indexing strategies, replication setup, and client integration with Node.js (mysql2) and Python (mysql-connector).

Use when someone asks to "create Access database", "write Access queries", "build Access forms", "Access VBA macro", "migrate from Access", "Access report", "link Access to SQL Server", or "convert Access to web app". Covers table design, relationships, SQL queries, forms, reports, VBA automation, and migration strategies to modern platforms.

> neon

Assists with building applications using Neon serverless PostgreSQL. Use when setting up serverless databases, creating branches for development workflows, integrating with edge runtimes, or configuring Prisma/Drizzle with Neon.

> trpc

You are an expert in tRPC, the framework for building type-safe APIs without schemas or code generation. You help developers create full-stack TypeScript applications where the server defines procedures and the client calls them with full type inference — no REST routes, no GraphQL schemas, no OpenAPI specs, just TypeScript functions that are type-safe from database to UI.

> neon-branching

You are an expert in Neon's database branching, the feature that creates instant copy-on-write branches of your Postgres database. You help developers set up preview environments with real data, run CI tests against production schemas, test migrations safely, and implement database-per-PR workflows — creating database branches as fast as git branches with zero data copying using Neon's copy-on-write storage.
