Best agent Skills for databases
The best agent Skill for databases depends on your stack, and the strongest picks are vendor-published: supabase-skill for Supabase/Postgres (RLS-correct by default) and planetscale-skills for PlanetScale/MySQL (Git-style migrations). For the ORM layer use prisma-orm; for MongoDB use mongodb-patterns; for a caching layer use redis-cache-patterns.
Database conventions vary enormously, so a Skill that knows your engine — its RLS model, migration workflow, index rules, and query dialect — produces far better output than generic SQL. Match the Skill to the database you actually run.
Top pick
supabase-skillPublished by Supabase. Writes RLS-correct Postgres — row-level-security policies, edge functions, realtime, and auth flows — the parts of Supabase agents most often get wrong.
Best when: You're on Supabase or Postgres and want secure queries by default.

Why these
Pick by pick
- 1supabase-skill
Published by Supabase. Writes RLS-correct Postgres — row-level-security policies, edge functions, realtime, and auth flows — the parts of Supabase agents most often get wrong.
- 2planetscale-skills
Published by PlanetScale. Schema branching and index-aware query generation with a Git-style migration workflow — MySQL/Vitess done the PlanetScale way.
- 3prisma-orm
Prisma's own skill. Keeps schema, migrations, and queries index-aware, migration-safe, and type-correct — the ORM layer rather than the database engine itself, from the vendor that ships Prisma.
- 4mongodb-patterns
MongoDB's official agent skills: aggregation pipelines, indexing strategies, and schema conventions — so the agent writes correct pipelines on the first try instead of N+1 queries.
- 5redis-cache-patterns
Redis's official agent skills: caching done safely — invalidation, write-through, cache-aside, and distributed locks, the patterns that are easy to get subtly wrong.
FAQ
Common questions
What is the best Claude skill for databases?
It depends on your database. For Supabase or plain Postgres, supabase-skill is the pick — it is published by Supabase and writes row-level-security-correct queries, edge functions, realtime, and auth by default. For PlanetScale/MySQL, planetscale-skills brings schema branching and Git-style migrations. Both are vendor-published, which is the strongest provenance for stack-specific database work.
Which skill is best for schema design and migrations?
For a TypeScript backend, prisma-orm — it keeps Prisma schema, migrations, and queries index-aware, migration-safe, and type-correct, so migrations stay reviewable. If your migrations run on PlanetScale, planetscale-skills gives you branch-based, deploy-request migration workflows instead. The right pick is the one that matches how your team already ships schema changes.
Are there skills for MongoDB and Redis?
Yes. mongodb-patterns covers aggregation pipelines, indexing, and schema conventions so the agent writes correct pipelines instead of N+1 queries. redis-cache-patterns covers caching done safely — invalidation, write-through, cache-aside, and distributed locks — which are the parts teams most often get subtly wrong. Both are catalogued community skills verified on Claude Code and Cursor.
Should I use a database skill or an MCP server?
A Skill encodes how to write against your database — the schema conventions, the RLS model, the migration workflow. An MCP server gives the agent a live connection to run queries against the actual database. They compose: the MCP executes, the Skill knows what correct SQL for your engine looks like. See skills vs subagents vs MCP vs plugins for the distinction.
