Harness for autonomous software development. Enforces lifecycle through alignment gates (PROJECT.md), adversarial generator/evaluator agents, CI/CD pipeline automation, and strict Git workflows (Conventional Commits, Branching).

Master the Bun all-in-one toolkit — runtime, package manager, test runner, and bundler.

Production-grade Docker and container best practices. Use when writing Dockerfiles, configuring Docker Compose, optimizing image size and build speed, implementing security hardening, or debugging container issues. Triggers on "Docker", "Dockerfile", "container", "Compose", "BuildKit", "multi-stage build", "image size", "docker-compose".

Master GitHub Actions CI/CD workflows with production-grade security and performance patterns. Use when writing workflow YAML, configuring CI/CD pipelines, setting up matrix strategies, caching dependencies, managing artifacts, or implementing reusable workflows. Triggers on "GitHub Actions", "CI/CD", "workflow", "actions/checkout", "matrix strategy", "reusable workflow", "SHA pinning", ".github/workflows".

Structured workflows for triaging GitHub issues, reviewing PRs, sprinting through milestones, and running security/quality/performance audits — with configurable validation gates, auto-detected security scanning, journal audit trails, and human-in-the-loop checkpoints. Use this skill whenever you are working on a GitHub issue, reviewing or submitting a PR, running any kind of code audit, updating dependencies, or working through a milestone. Also use when the user mentions issue numbers, PR numbers, milestone names, or asks you to "fix", "triage", "audit", "review", or "update deps".

Documentation and instructions for integrating the GitHub Copilot CLI (`copilot`) into agentic workflows. Use this skill when you need a "second opinion" adversarial review of a local codebase, a pre-push PR review using alternative advanced models, or shell suggestion capabilities from GitHub. Activates on "Copilot CLI", "local PR review", or "codebase Copilot review".

Specialized assistant skill for managing repositories and CI/CD in GitLab. Activate when the user asks about GitLab projects or repositories, wants to see merge requests or pipelines, needs to search code or files, asks about CI/CD status or job logs, or wants to browse repository contents. Mentions "GitLab", "MR", "pipeline", or "CI/CD".

Master Go development using production-grade best practices merged from the Google and Uber style guides. Use whenever writing Go code, designing APIs, handling errors, managing goroutines, or configuring linters.

Enterprise MySQL & MariaDB production rules — query safety, connection pooling, and strict schema configurations.

Comprehensive, opinionated guidance for Playwright test development. Use when writing E2E, API, component, or visual tests, debugging failures, implementing Page Object Model, or configuring CI/CD. Includes "Golden Rules" for resilient tests and provides on-demand reference for specialized scenarios (Electron, WebSockets, mobile, security audits).

Enterprise PostgreSQL production rules — advanced querying, indexing, JSONB data, and strict optimization patterns.

Master modern Python development with production-grade tooling and idioms. Use when writing Python code, configuring project structure, managing dependencies with uv, linting with ruff, adding type hints, writing pytest tests, or building FastAPI/Django/Flask applications. Triggers on "Python", "FastAPI", "Django", "Flask", "pytest", "uv", "ruff", "pyproject.toml".

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.

Master Rust development using a layer-based "meta-cognition" framework. Use whenever writing Rust code, resolving borrow checker errors (E0382, E0596), designing ownership patterns (Arc, Mutex), or performing crate selection.

Give your AI assistant deep knowledge of shadcn/ui components, patterns, and best practices.

Guide for creating, evaluating, and refining agent skills (.md files with YAML frontmatter). Use this skill whenever you are creating a new skill, improving an existing skill, reviewing skill quality, writing skill descriptions, or when the user asks about skill structure, progressive disclosure, or best practices for agent instructions. Also use when someone says "turn this into a skill", "make a skill for X", or "improve this skill".

Enforced meta-cognitive rules and production configurations for SQLite development.

Master Tailwind CSS v4 with its CSS-first configuration paradigm. Use when writing utility classes, configuring design tokens via @theme, implementing dark mode, migrating from v3, or integrating with React/Vue/Svelte. Triggers on "Tailwind", "utility CSS", "Tailwind v4", "@theme", "dark mode classes", "responsive design", "Tailwind migration".

Master enterprise-grade TypeScript development with type-safe patterns, modern tooling, and framework integration. This skill provides comprehensive guidance for TypeScript 6.0+, covering type system fundamentals (generics, mapped types, conditional types, satisfies operator), enterprise patterns (error handling, validation with Zod), React integration for type-safe frontends, NestJS for scalable APIs, and LangChain.js for AI applications. Use when building type-safe applications, migrating JavaScript codebases, configuring modern toolchains (Vite 7, pnpm, ESLint, Vitest), implementing advanced type patterns, or comparing TypeScript with Java/Python approaches.

Comprehensive unit testing expertise covering Vitest, test-driven development (TDD), mocking strategies, and production-grade best practices. Activates for unit testing, Vitest, TDD, Red-Green-Refactor, mocking, stubbing, spying, test coverage, and test architecture in TypeScript/Node projects.
