integrating-supabase

integrating-supabase is a skill for Claude Code, Codex from Poorgramer-Zack/dart-expert-skills. It costs 44 tokens per session (558 once invoked), scanned A, original, MIT.

A guide for connecting Flutter apps to Supabase, an open-source backend platform built around PostgreSQL. It covers database access, user authentication, live data updates, file storage, server-side functions, and database access rules.

In plain words
What is it for?
Use it to configure Supabase in Flutter, add login, query PostgreSQL data, subscribe to realtime changes, store files, call Edge Functions, and write Row Level Security policies.
Why use it?
It brings common backend services together through the supabase_flutter package, reducing the need to build each service separately. It also explains when privileged operations should run through a protected backend layer.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

integrating-supabase scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 31 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Supabase Flutter Ecosystem (supabase_flutter)

Goal

Supabase is an open-source Firebase alternative built on PostgreSQL, supporting rich SQL queries, table joins, and a first-class Flutter SDK (supabase_flutter).

To ensure modularity and LLM readability, this skill is split into logical chapters. Before answering questions or writing code related to Supabase, you MUST read the relevant reference chapters.

Process/Workflow

  1. Identify the core Supabase service the user needs (Database, Auth, Storage, etc.).
  2. Read the corresponding chapter(s) from the references/ directory.
    • Example: If the user asks about deep linking Magic Links for login, read 01-setup.md and 02-auth.md.
  3. Synthesize the guidelines exactly as documented within the chapters. DO NOT hallucinate third-party packages or outdated practices.
  4. Maintain the Serverpod Mini BFF (Backend-For-Frontend) architecture whenever the user requires executing high-privilege operations that should bypass Row Level Security (RLS) entirely.

Reference Files

  • Setup & Deep Links: Read 01-setup.md for core initialization and the app_links requirement.
  • Authentication: Read 02-auth.md for Email/OTP, Apple/Google native sign-in, and listening to stream changes.
  • Database (Postgres): Read 03-database.md for strongly-typed Freezed mapping, .select(), and join strategies natively.
  • Realtime & Presence: Read 04-realtime.md for Postgres CDC subscriptions and User Presence management.
  • Storage: Read 05-storage.md for cross-platform (Mobile vs Web) bucket manipulation.
  • Edge Functions: Read 06-edge-functions.md for executing remote serverless workflows.
  • Serverpod Mini (BFF): Read 07-serverpod-mini.md for leveraging the pure supabase Dart library combined with the SERVICE_ROLE_KEY inside a secure backend.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
