What are AI agent skills?

AI agent skills are reusable, curated instruction sets that help coding agents and AI tools perform tasks more accurately. Instead of relying solely on the model's training data, skills deliver up-to-date, verified guidance directly to your agent at runtime through the Model Context Protocol (MCP), REST API, or the official TypeScript SDK.

Milkey provides a hosted library of skills covering frameworks, databases, cloud platforms, DevOps practices, and more. Each skill is versioned and quality-rated with a trust score so you can confidently rely on the guidance your agent receives.

Whether you use Cursor, Claude Code, Windsurf, Codex, or any MCP-compatible client, Milkey skills integrate seamlessly. Connect once, enable the skills you need, and your agent automatically resolves the right instructions for each task.

Frequently asked questions

What are AI agent skills?

AI agent skills are reusable, versioned instruction sets that help coding agents and AI tools perform tasks more accurately. They provide up-to-date best practices, configuration guidance, and domain-specific knowledge delivered through MCP, REST API, or the TypeScript SDK.

How do I use Milkey skills with my AI code editor?

Connect your AI code editor (Cursor, Claude Code, Windsurf, Codex, or others) to Milkey using the hosted MCP server. Once connected, skills are automatically resolved and delivered to your agent at runtime — no manual copying or pasting required.

Are Milkey skills free?

Milkey offers a free plan with access to community skills. Premium skills and higher usage limits are available on paid plans. Browse the full skills catalog to see what is included in each tier.

What is a trust score?

Each skill has a trust score from 1 to 10 that reflects the quality and reliability of its instructions. Higher scores indicate well-tested, thoroughly documented skills that are more likely to produce correct results.

How often are skills updated?

Skills are versioned and updated regularly to keep pace with framework changes, security patches, and best practice improvements. When a skill is updated, the version number increments and your agent automatically receives the latest version.
