supabase
Comprehensive Supabase development skill covering all Supabase products and
integrations.
Use when:
- Working with any Supabase product (Database, Auth, Edge Functions, Realtime,
Storage, Vectors, Cron, Queues) - Using client libraries and SSR integrations (supabase-js, @supabase/ssr) in
Next.js, React, SvelteKit, Astro, Remix - Troubleshooting auth issues (login, logout, sessions, JWT, cookies, getSession,
getUser, getClaims, RLS) - Using the Supabase CLI or MCP server
- Working with schema changes, migrations, security audits, or Postgres extensions
(pg_graphql, pg_cron, pg_vector)
supabase-postgres-best-practices
Postgres performance optimization guidelines from Supabase. Contains references
across 8 categories, prioritized by impact.
Use when:
- Writing SQL queries or designing schemas
- Implementing indexes or query optimization
- Reviewing database performance issues
- Configuring connection pooling or scaling
- Working with Row-Level Security (RLS)
Categories covered:
- Query Performance (Critical)
- Connection Management (Critical)
- Schema Design (High)
- Concurrency & Locking (Medium-High)
- Security & RLS (Critical)
- Data Access Patterns (Medium)
- Monitoring & Diagnostics (Low-Medium)
- Advanced Features (Low)
Usage
Skills are automatically available once installed. The agent will use them when
relevant tasks are detected.
Examples:
Optimize this Postgres queryReview my schema for performance issuesHelp me set up Supabase Auth with Next.jsHelp me add proper indexes to this tableSkill Structure
Each skill follows the Agent Skills Open Standard:
SKILL.md- Required skill manifest with frontmatter (name, description, metadata)references/- (Optional) Reference files for detailed documentation
.well-known discovery
Each release uploads a dist/index.json alongside the skill tarballs. This index conforms to the agent-skills .well-known URI spec (schema v0.2.0) and is consumed by supabase.com to serve skills at https://supabase.com/.well-known/agent-skills/.
The release artifacts are built by scripts/build-release.ts and triggered by Release Please on every semver release.
Migrating to the official GitHub Action
jonathanhefner/agentskills-build-for-well-known is intended to be transferred to the agentskills org and published to the GitHub Marketplace. When that happens, scripts/build-release.ts and the pnpm build:release step in release-please.yml can be replaced with the Action directly:
- name: Build release artifacts
uses: agentskills/build-for-well-known@v1 # replaces pnpm build:release
with:
skills-dir: skills
output-dir: distEverything else — the Release Please trigger, the upload step, the supabase-plugin dispatch — stays exactly the same. The script and the Action produce identical output, so it is a drop-in swap.

How to use this skill
Install skill-creator by running npx skills add supabase/agent-skills --skill skill-creator in your project directory. Run the install command above in your project directory. The skill file will be downloaded from GitHub and placed in your project.
No configuration needed. Your AI agent (Claude Code, Cursor, Windsurf, etc.) automatically detects installed skills and uses them as context when generating code.
The skill enhances your agent's understanding of skill-creator, helping it follow established patterns, avoid common mistakes, and produce production-ready output.
What you get
Skills are plain-text instruction files — not executable code. They encode expert knowledge about frameworks, languages, or tools that your AI agent reads to improve its output. This means zero runtime overhead, no dependency conflicts, and full transparency: you can read and review every instruction before installing.
Compatibility
This skill works with any AI coding agent that supports the skills.sh format, including Claude Code (Anthropic), Cursor, Windsurf, Cline, Aider, and other tools that read project-level context files. Skills are framework-agnostic at the transport level — the content inside determines which language or framework it applies to.
