Best Claude Skills for Database Work in 2026: 15 Compared
Top 15 Claude skills for database work. Supabase leads with two 5/5-quality skills; database vendors are publishing official skills as a competitive moat.
Database Work is 2026's clearest example of vendor competition through Claude skills. Supabase, Firebase, Convex, and Neon all publish official skills under their own GitHub orgs — and they're competing for install signal the same way they compete for developer mindshare. Supabase leads with two 5/5-quality entries (130K + 41K install signal); Firebase, Convex, and Neon each get a 3/5-quality skill at 30K+ installs. The 2026 shift: when you pick a database, you're now also picking which Claude experience you want. The vendor who ships the best skill wins downstream adoption.
Quick Pick
Supabase Postgres Best Practices — 130K signal, 5/5 quality, published by Supabase themselves. Covers RLS, indexes, migrations, efficient queries, schema design. Install this even if you're not on Supabase — the Postgres patterns are universally applicable.
What These Skills Actually Do
Database skills cluster into four patterns: (1) Vendor-official best-practices (#1 Supabase, #3 Supabase Bundle, #4 Firebase, #5 Convex, #6 Neon) — five of the top six entries are official publications from the database vendors themselves. (2) Cross-database toolkits (#8 SQL Toolkit, #9 Database Operations) — work across SQLite/Postgres/MySQL. (3) Single-database wrappers (#11 Supabase community, #12 Supabase Complete Docs, #13 SQLite, #14 MySQL) — community alternatives to the official vendor skills. (4) SaaS data sources (#2 Notion as database, #7 Stripe as queryable customer DB, #10 Airtable, #15 DingTalk AI Table). The fourth pattern is the 2026 surprise — non-database services treated as databases — and the install signal validates it (Notion is the #2 most-installed skill in this list).
How We Ranked
We sorted 15 candidate skills by a composite score:
- Popularity signal — the highest of GitHub stars, install count, or ClawHub download count. Log-scaled so a 100-star skill doesn't get buried under a 100,000-star one if the smaller one is meaningfully better.
- Quality score — when set, a 0–5 rubric that breaks ties within popularity tiers. Roughly 15% of catalog skills carry a quality score today; we surface it in the comparison table when available.
The formula is identical across the entire Best-Of 2026 series, so you can compare apples to apples between categories.
The Top 15
1. Supabase Postgres Best Practices
Plugin · supabase/agent-skills · 130.6K signal · quality 5/5 Idiomatic PostgreSQL — RLS, indexes, migrations, efficient queries, schema design.
The take: Official Supabase publication, top of the category by every metric. The RLS coverage is the differentiator — Row Level Security is where most teams hit subtle bugs, and the skill encodes Supabase's hard-won patterns. Universally applicable even off Supabase.
2. notion (Hermes)
Skill · NousResearch/hermes-agent · 124.8K signal · quality 4/5 Notion API via curl — pages, databases, blocks, search.
The take: Notion treated as a database. Surprising #2 placement reveals that many teams use Notion databases as their actual operational store. The 4/5 quality on Hermes's curl-based implementation is unusually high for a third-party API wrapper.
3. Supabase Agent Skills Bundle
Plugin · supabase/agent-skills · 41.6K signal · quality 5/5 Postgres best practices + full Supabase platform patterns.
The take: The bundle version of #1 — adds auth, storage, edge functions, realtime alongside the Postgres core. Install this instead of #1 if you use the broader Supabase platform; install #1 alone if you only use the Postgres half.
4. Firebase Firestore Best Practices
Plugin · firebase/agent-skills · 35.5K signal · quality 3/5 Data modeling, queries, security rules, batch operations, performance.
The take: Google's official Firebase skill. 3/5 vs Supabase's 5/5 reflects the relative depth — Firestore's model is simpler (no joins, document-based) so there's less ground to cover. Install if Firebase is your stack.
5. Convex Quickstart
Plugin · get-convex/agent-skills · 34.6K signal · quality 3/5 Convex real-time backend — data modeling, queries, mutations, actions, React integration.
The take: Official Convex skill. The realtime-and-functions model is the differentiator — most Postgres-shaped DBs need extra plumbing for realtime, Convex bakes it in. Install for serverless-realtime workloads.
6. Neon Serverless Postgres
Plugin · neondatabase/agent-skills · 28.9K signal · quality 3/5 Neon serverless Postgres — branching, connection pooling, edge functions, cost-efficient patterns.
The take: Official Neon skill. Database branching is Neon's killer feature (clone a DB for each PR, just like git). The skill covers branching idioms most general Postgres skills don't touch.
7. Stripe (PaymentsDB)
Skill · clawhub/stripe · 19.0K signal · quality unrated Query Stripe customer/billing data from a synced Postgres mirror.
The take: Treats Stripe as a queryable database. Mirrors Stripe's data into Postgres so Claude can run arbitrary SQL over customers, subscriptions, invoices. Better than Stripe's API for analytical queries.
8. SQL Toolkit
Skill · gitgoodordietrying/sql-toolkit · 13.4K signal · quality unrated Query, design, migrate, optimize SQL — SQLite, Postgres, MySQL.
The take: Cross-DB toolkit (also #15 in Data & Analytics). Useful when you work across multiple databases or want a universal query/migration interface.
9. Database Operations
Skill · jgarrison929/database-operations · 10.0K signal · quality unrated Schema design, migrations, query optimization, N+1 fixes, indexes, EF Core, caching, partitioning.
The take: Practitioner-flavored — written for people who actually maintain databases at scale. The "fix N+1 problems" and "partitioning" coverage is rare; most skills stop at "write a query."
10. Airtable
Skill · byungkyu/airtable · 7.7K signal · quality unrated Airtable API with managed OAuth — bases, tables, records, filter formulas.
The take: Airtable-as-database. Managed OAuth removes the auth-pain. Useful for ops teams whose source of truth lives in Airtable.
11. Supabase (community)
Skill · lucassynnott/supabase · 7.4K signal · quality unrated Supabase ops — SQL, pgvector similarity search, storage.
The take: Community alternative to #1. Less authoritative than the official skill; redundant if you have #1 or #3.
12. Supabase Complete Documentation
Skill · leonaaardob/lb-supabase-skill · 7.2K signal · quality unrated Complete Supabase docs — auth, DB, storage, edge functions, realtime, etc.
The take: Documentation-as-skill. Useful when you want Claude to look up Supabase docs rather than execute against them. Pair with #1 for the practice+reference combo.
13. SQLite
Skill · ivangdavila/sqlite · 5.0K signal · quality unrated SQLite — concurrency, pragmas, type handling.
The take: SQLite has weirder quirks than people think (WAL mode, journal modes, type affinity). The skill encodes them. Install for SQLite-backed apps (mobile, desktop, prototyping).
14. MySQL
Skill · ivangdavila/mysql · 3.6K signal · quality unrated MySQL — character sets, indexes, locking.
The take: Cross-listed (#2 in Backend & API). MySQL-specific footguns. Install for MySQL stacks.
15. Dingtalk Ai Table
Skill · aliramw/dingtalk-ai-table · 3.6K signal · quality unrated DingTalk AI Table (multidimensional table) — base/table/field/record operations.
The take: China-market — DingTalk (Alibaba's workplace platform) has a multidimensional-table feature that's the de-facto "Notion replacement" for many Chinese enterprises. Install if your data lives there.

FAQ
How is this list different from the category page on aiskill.market?
The category page is a directory: every skill in the category, sortable and filterable. This list is editorial — opinionated, time-stamped (2026-05-18), and ranked. Use the directory when you know what you want; use this when you don't.
Why does the #1 pick have fewer stars than #5?
Stars are one signal among several. The composite score above also includes install counts (which reflect actual usage on aiskill.market) and the optional quality score. A skill with a smaller star count can rank higher if its installs or quality score are strong enough to offset.
Are these all free?
Skills are MIT-licensed. Underlying services vary: Supabase has a free tier; Firebase Spark plan is free; Convex and Neon have generous free tiers; Airtable charges per record; Stripe is free to access (you pay for transactions). DingTalk requires a Chinese-org account.
How do I install one?
Each linked skill page has install instructions. The fastest path is the one-line install via the aiskill.market CLI or by adding the source repo as a Claude Code plugin marketplace.
How often does this list update?
Quarterly. Database-vendor skills update faster than this article — vendors push their own changes to their official repos. Always pull the latest from the vendor's GitHub for cutting-edge features.
Why do database vendors publish official Claude skills?
Because winning the AI workflow is now part of winning database market share. A developer evaluating Supabase vs Neon in 2026 will install both Claude skills, prompt against each, and judge which experience feels better. The skill quality is now part of the product.
What's the right starter pack for database work?
Two skills: #1 Supabase Postgres Best Practices (universally useful Postgres patterns) + the vendor-official skill for your DB (#4 Firebase, #5 Convex, #6 Neon, etc.). Add #8 SQL Toolkit if you work across multiple databases.
