Microsoft Agent Skills

Agent Skills is an open-source repository by Microsoft providing 132 domain-specific knowledge files (skills) that activate correct SDK patterns in AI coding agents like GitHub Copilot. It covers Azure SDKs across Python, .NET, TypeScript, Java, and Rust, along with custom agent personas, reusable prompt templates, and pre-configured MCP server setups. Skills are installed via a simple CLI wizard and symlinked across agent configurations, making it easy to share context across multiple agents in the same project. The repository is under active development with a built-in test harness that validates generated code against acceptance criteria.

• 132 Skills across 6 languages — Domain-specific knowledge files for Azure SDK and Foundry development covering Python (41), .NET (28), TypeScript (25), Java (25), Rust (7), and Core (9) skills.
• 1-click install via CLI — Run npx skills add microsoft/skills to launch a wizard that installs only the skills you need into your agent's directory (e.g., .github/skills/).
• Skill Explorer — Browse all 132 skills with descriptions and 1-click install at the hosted GitHub Pages documentation site.
• Installable Plugins — Bundled plugin packages like deep-wiki (AI-powered wiki generator) and azure-skills (Azure MCP integration) installable via Copilot CLI slash commands.
• Custom Agent Personas — Role-specific agent definitions for backend, frontend, infrastructure, planner, and presenter roles, configurable via the AGENTS.md template.
• MCP Server Configurations — Pre-configured MCP server references for documentation (microsoft-docs, context7, deepwiki), development (github, playwright, terraform), and utilities (memory, markitdown).
• Test Harness with Ralph Loop — 1,158 test scenarios validate skill quality; the Ralph Loop iteratively generates, evaluates, and re-generates code until a quality threshold is met.
• Reusable Prompt Templates — Structured prompts for code review, Zustand store creation, React Flow node creation, and FastAPI endpoint generation.
• AGENTS.md Template — A ready-to-use template for configuring agent behavior, tool access, and skill loading in any project.
• Selective Context Loading — Skills are designed to be loaded selectively to avoid context rot—only copy skills essential for your current project.
