> electric-sql-sdk

You are an expert in Electric SQL, the sync engine that streams Postgres data to local apps in real-time. You help developers build local-first applications where data syncs from Postgres to client-side SQLite/PGlite automatically — enabling instant reads, offline support, and real-time multi-user collaboration using Postgres as the single source of truth with Shape-based partial replication.

> grafana

Grafana is an open-source visualization and dashboarding platform that connects to dozens of data sources including Prometheus, PostgreSQL, ClickHouse, and Elasticsearch. It lets you build interactive dashboards with panels, set up alerting rules, and manage everything as code through JSON dashboard definitions and provisioning configuration.

> security-audit

Scan code for security vulnerabilities, misconfigurations, and exposed secrets. Use when a user asks to audit security, find vulnerabilities, check for OWASP issues, scan for secrets, review dependencies for CVEs, detect SQL injection, find XSS vulnerabilities, or harden an application. Covers OWASP Top 10, dependency auditing, secrets detection, and generates fix recommendations with severity ratings.

> 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.

> electric-sql

Build local-first applications with ElectricSQL — sync Postgres data to client devices in real-time. Use when someone asks to "sync database to client", "local-first app", "ElectricSQL", "offline-first sync", "real-time Postgres sync", "sync Postgres to SQLite", or "build an app that works offline". Covers shape-based sync, real-time subscriptions, offline support, and conflict resolution.

> supabase

Build applications with Supabase as the backend — Postgres database, authentication, real-time subscriptions, storage, and edge functions. Use when someone asks to "set up Supabase", "add authentication", "create a real-time app", "set up row-level security", "configure Supabase storage", "write edge functions", or "migrate from Firebase to Supabase". Covers project setup, schema design with RLS, auth flows, real-time subscriptions, file storage, and edge functions.

> pglite

You are an expert in PGlite, the lightweight WASM Postgres build that runs in the browser, Node.js, and Deno. You help developers embed a full Postgres instance (with extensions like pgvector, PostGIS) in client-side apps, Electron, React Native, and serverless functions — providing real SQL with JSONB, full-text search, and vector similarity search at ~3MB compressed, without a server.

> sqlite

SQLite is a self-contained, serverless, zero-configuration embedded SQL database engine. Learn CLI usage, Node.js integration with better-sqlite3, Python's built-in sqlite3 module, and best practices for schema design, indexing, and WAL mode.

> val-town

Write and deploy server-side TypeScript functions instantly with Val Town. Use when someone asks to "deploy a function quickly", "serverless TypeScript", "quick API endpoint", "webhook handler", "cron job in the cloud", "Val Town", "instant API without infrastructure", or "deploy a script without a server". Covers HTTP vals, cron vals, email vals, SQLite storage, and the Val Town API.

> ibis

Expert guidance for Ibis, the Python dataframe library that provides a pandas-like API but generates SQL for execution on any backend — DuckDB, PostgreSQL, BigQuery, Snowflake, Spark, and more. Helps developers write analytics code once and run it anywhere without rewriting SQL for each database.

> val-town-sdk

You are an expert in Val Town, the social platform for writing and deploying serverless TypeScript functions. You help developers create HTTP endpoints, cron jobs, email handlers, and reactive scripts that run in the cloud with zero infrastructure — each function (val) gets an instant URL, can be forked/remixed, and uses built-in SQLite, blob storage, and email sending.

> sql-pro

Master modern SQL with cloud-native databases, OLTP/OLAP optimization, and advanced query techniques. Expert in performance tuning, data modeling, and hybrid analytical systems. Use PROACTIVELY for database optimization or complex analysis.

> sql-query-optimizer

> using-dbt-for-analytics-engineering

Builds and modifies dbt models, writes SQL transformations using ref() and source(), creates tests, and validates results with dbt show. Use when doing any dbt work - building or modifying models, debugging errors, exploring unfamiliar data sources, writing tests, or evaluating impact of changes.

> database-migrations

Database migration best practices for schema changes, data migrations, rollbacks, and zero-downtime deployments across PostgreSQL, MySQL, and common ORMs (Prisma, Drizzle, Django, TypeORM, golang-migrate). Use when planning or implementing database schema changes.

> sql-queries

Generate SQL queries from natural language descriptions. Supports BigQuery, PostgreSQL, MySQL, and other dialects. Reads database schemas from uploaded diagrams or documentation. Use when writing SQL, building data reports, exploring databases, or translating business questions into queries.

> nestjs-security-isolation

Enforce multi-tenant isolation and PostgreSQL Row Level Security in NestJS. Use when enforcing tenant isolation or PostgreSQL RLS in NestJS multi-tenant apps. (triggers: src/modules/**, SECURITY.md, src/migrations/**, RLS, Row Level Security, childId, isolation, access policy)

> sql-optimization-patterns

Master SQL query optimization, indexing strategies, and EXPLAIN analysis to dramatically improve database performance and eliminate slow queries. Use when debugging slow queries, designing database schemas, or optimizing application performance.

> managing-database-migrations

This skill enables Claude to manage database schema changes through version-controlled migrations. It is activated when the user requests to create, apply, or rollback database migrations. The skill supports generating timestamped migration files with both up and down migrations for PostgreSQL, MySQL, SQLite, and MongoDB. It helps in tracking schema evolution and ensuring safe database modifications. Use this skill when the user mentions "database migration", "schema change", "add column", "roll
