At a glance

A skill your agent uses when doing ANY task involving Supabase.

  • Works in 3 steps: Check if the server is reachable → Check .mcp.json configuration → Authenticate the MCP server
  • Doing ANY task involving Supabase
  • SKILL.md covers Core Principles, Supabase CLI, Supabase MCP Server and Supabase Documentation, plus 2 more sections
  • Calls supabase and curl; reaches supabase.com and mcp.supabase.com

What it does

Supabase is an agent skill from curvenote/curvenote. Use when doing ANY task involving Supabase. Triggers: Supabase products (Database, Auth, Edge Functions, Realtime, Storage, Vectors, Cron, Queues); client libraries and SSR integrations (supabase-js, @supabase/ssr) in Next.js, React, SvelteKit, Astro, Remix; auth issues (login, logout, sessions, JWT, cookies, getSession, getUser, getClaims, RLS); Supabase CLI or MCP server; schema changes, migrations, security audits, Postgres extensions (pggraphql, pgcron, pgvector).

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files and assets (for example `assets/feedback-issue-template.md` and `references/skill-feedback.md`).

It sits in Backend & APIs, covering Scheduled and recurring tasks, Static sites and blogs and Authentication. It works with Supabase, Model Context Protocol, PostgreSQL and Astro. The repository describes itself as: Create, edit, share, and publish scientific and technical documents.

When your agent uses it

  • Doing ANY task involving Supabase
  • Tasks that involve Scheduled and recurring tasks
  • Tasks that involve Static sites and blogs

Example prompts

  • “/supabase”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Check if the server is reachable
  2. Check .mcp.json configuration
  3. Authenticate the MCP server

What it can do on your machine

Read from SKILL.md and the folder at commit 91febfe. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • supabase
    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • supabase.com
    • mcp.supabase.com

    Also links to:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Supabase loads about 2.2k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 1,112 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~121
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,112 words (~2,204 tokens).

“1. Supabase changes frequently — verify against changelog and current docs before implementing. Do not rely on training data for Supabase features. Function signatures, config.toml settings, and API conventions change between versions.”
