Includes ALL databases (PostgreSQL, MongoDB, Redis, Elasticsearch), ALL features (REST, GraphQL, WebSockets, gRPC, Message Queues), comprehensive security hardening (XSS, CSRF, SQL injection, authentication, authorization, rate limiting), complete performance optimization (caching, database tuning, load balancing), ALL deployment strategies (Docker, Kubernetes, CI/CD), advanced patterns (microservices, event-driven, saga, CQRS), ALL use cases (e-commerce, SaaS, real-time, high-traffic), complete testing (unit, integration, E2E, load, security). Route protection, middleware, authentication implementation in PERFECTION. Use for ANY backend system requiring enterprise-grade security, performance, scalability, and architectural excellence.

Manage git worktrees for parallel branch development using custom git scripts (git-newtree, git-killtree, git-maingulp). Use when creating new worktrees, listing active worktrees, or closing/merging worktrees back to main. All worktrees are stored in .tree/ subdirectories of the repository.

Comprehensive backend development skill for building scalable backend systems using NodeJS, Express, Go, Python, Postgres, GraphQL, REST APIs. Includes API scaffolding, database optimization, security implementation, and performance tuning. Use when designing APIs, optimizing database queries, implementing business logic, handling authentication/authorization, or reviewing backend code.

Create isolated git worktrees at bare repo root level

Generate lint-staged configuration for running linters on staged Git files. Triggers on "create lint-staged config", "generate lint staged", "lint-staged setup", "staged file linting".

Reviews pull requests created by GitHub Copilot agents before merging. Triggers on "review this PR", "check PR

Validate skills against agentskills.io specification. Use when adding new skills to the marketplace, reviewing skill PRs, checking skill compliance, or running quality gates on skills. Validates frontmatter fields (name, description, license, compatibility, metadata, allowed-tools), directory naming, line limits, and structure.

Determines minimal context and routes tasks to the correct prompts, agents and tools.
