In Cursor chat, add this repository as a plugin:
/add-plugin database-skills
Plan and review MySQL/InnoDB schema, indexing, query tuning, transactions, and operations. Use when creating or modifying MySQL tables, indexes, or queries; diagnosing slow or locking behavior; planning migrations; or troubleshooting replication and connection issues.
Guidance for Neki, PlanetScale's distributed (sharded) Postgres. Use when working with a Neki database — connecting, data topology and shard keys, query routing and fanout, cross-shard transactions, schema changes, resharding and migration, NK013 errors — or when scaling and sharding Postgres.
PostgreSQL best practices, query optimization, connection troubleshooting, and performance insights for PlanetScale Postgres. Use when working with PlanetScale PostgreSQL databases — schema design, indexing, MVCC/VACUUM, WAL tuning, replication, monitoring, or PlanetScale-specific features like connection pooling and CLI insights.
Vitess best practices, query optimization, and connection troubleshooting for PlanetScale Vitess databases. Use when working with sharding, VSchema configuration, keyspace management, online DDL, VReplication, or MySQL-compatible scaling issues.

Reads text from scanned pages, photos and PDFs and returns it as structured Markdown or JSON, so you can pull tables, formulas and headers out of a document without retyping them. Covers many languages and works as input for AI tools.
@paddlepaddleGives your AI assistant a memory that persists across sessions, so it remembers your preferences and earlier work in this repository instead of starting fresh. Search, forget, pause and resume memories with simple commands.
@mem0aiGives AI agents a library of ready-made skills for scientific work such as metabolic flux analysis, protein experiment design, time series modeling, and analytical method validation, so research tasks need less hand-built code. It works with any agent that supports the open Agent Skills standard.
@k-dense-aiGives Claude Code skills, agents, and commands for PostHog analytics, session replay, feature flags, error tracking, and LLM observability. Includes MCP server setup and project access checks.
@posthogInstall it with the command on its page. It includes mysql, neki, postgres. Its skills do not fire on their own yet. Free and open source.
