This skill translates complex business requirements and specification documents into a complete, production-ready Postgres schema for Supabase. It covers the full development lifecycle, including entity extraction, defining robust tables with constraints, generating migration SQL files, implementing Row Level Security (RLS) policies, and producing corresponding TypeScript types. It is the foundational step for building any robust SaaS application on Supabase.

This skill provides a comprehensive guide to securing Supabase projects. It covers critical security measures, including proper separation of anonymous and service role keys, enforcing Row Level Security (RLS) on all tables, and hardening the API surface. Use this when setting up a new project, performing security audits, or implementing robust data access control policies.

A comprehensive guide for migrating and upgrading the Supabase SDK (JS/TS and Python) and CLI. This tool detects breaking changes, covers major version jumps (e.g., v1 to v2), and provides automated code migration patterns for Auth, Realtime, and Storage APIs. Use this when updating your project to a new Supabase version or when encountering API deprecations.

A comprehensive guide to building event-driven architectures using Supabase. It covers four core event mechanisms: Database Webhooks (pg_net), Postgres LISTEN/NOTIFY, Edge Function HTTP calls, and Realtime subscriptions. Includes production-ready SQL triggers, signature verification logic, and best practices for handling data changes (INSERT, UPDATE, DELETE) as external HTTP events.

Guide for orchestrating Supadata operations via Composio’s Rube MCP workflow, covering tool discovery, connection checks, schema compliance, execution, and best practices for consistent automation.

Automate Svix operations through Composio’s Svix toolkit by orchestrating Rube MCP calls; follow the required discovery, connection, and execution steps to keep schemas current and workflows reliable.

Automates swagger documentation tasks by offering best-practice guidance, example code, and validation when working on REST, GraphQL, or OpenAPI-based API development requests.

This pattern demonstrates how to build a robust, thread-safe data persistence layer in Swift using the 'actor' model. It combines fast in-memory caching with reliable file-backed storage, automatically eliminating data races and the need for manual locks. Ideal for offline-first applications and managing shared mutable state in modern Swift concurrency.

A guide to the Swift 6.2 concurrency model, which mandates default single-threaded execution to eliminate accidental data races. Learn how to use MainActor for isolated consistency and utilize the @concurrent attribute for explicitly offloading CPU-intensive tasks to background threads, ensuring safe and predictable application architecture.

This expert guides you through building modern, high-performance applications across Apple platforms (iOS, macOS, watchOS, tvOS) using Swift 5.9+. It specializes in SwiftUI state management, Protocol-Oriented Architecture, concurrent programming with async/await and Actors, and implementing best practices for type safety and performance optimization. Ideal for developing complex, robust applications.

This comprehensive guide demonstrates how to achieve highly testable Swift code using protocol-based dependency injection. By abstracting external concerns—such as file systems, networking, and external APIs—into small, focused protocols, developers can write deterministic unit tests that mock side effects and error paths, ensuring robust architecture across different environments (App, Test, Preview).

An expert skill designed for writing, reviewing, and refactoring SwiftUI code for iOS and macOS. It provides deep insights into modern state management (@Observable), optimizing view composition, handling data flow, and improving performance. The skill also assists with interpreting Instruments traces and adhering to Apple's latest Human Interface Guidelines.
