Um guia prático para o primeiro dia de desenvolvimento de aplicações Rust, abordando modelos mentais, decisões chave, idiomatismos, anti-padrões e crates essenciais. Ideal para iniciar novos projetos em Rust.

Make n8n workflows idempotent, resumable, and safe at scale using MySQL/Postgres checkpoint tables, batch processing patterns, duplicate prevention, and dynamic table creation. Use this skill whenever the user is building an n8n workflow that processes batches of data, handles webhooks, polls APIs, or runs on a schedule — phrases like "idempotent pipeline", "batch processing", "don't process dupli

CLI automation for Supabase development workflows. Provides scripts for migrations, Edge Functions, secrets management, type generation, and SQL execution with safety checks.

This skill should be used when the user asks to "design REST APIs", "optimize database queries", "implement authentication", "build microservices", "review backend code", "set up GraphQL", "handle database migrations", or "load test APIs". Use for Node.js/Express/Fastify development, PostgreSQL optimization, API security, and backend architecture patterns.

Database design, SQL, NoSQL, and data management

Use when users want to remove or disconnect the mybrain plugin's persistent memory layer. Handles teardown for all database strategies (Docker, local PostgreSQL, remote PostgreSQL), config file removal, and offers a disconnect-only option that preserves the database.

SQL to OSC (Online Schema Change) conversion expert for Flyway migration scripts. Use when: (1) Converting SQL migration files to OSC format, (2) User mentions "OSC", "轉換 OSC", "osc.txt", or "Online Schema Change", (3) Working with Flyway ALTER TABLE/CREATE INDEX statements that need OSC conversion.

This skill should be used when the user asks about "dangerous functions", "security sinks", "what functions are dangerous in PHP/Java/Python", "find vulnerable functions", "code execution functions", "command injection sinks", "SQL injection functions", or needs to identify security-sensitive functions in source code during whitebox security review.

This skill should be used when the user asks about "vulnerability patterns", "how to find SQL injection", "XSS patterns", "command injection techniques", "OWASP vulnerabilities", "common web vulnerabilities", "exploitation patterns", or needs to understand how specific vulnerability classes work during whitebox security review.

Use when writing or reviewing code that parses user input, builds SQL/shell commands, handles secrets/credentials, hashes passwords, changes auth checks, deserializes untrusted data, or constructs paths/URLs from input
