Terms in this piece · Glossary

agent skill — A reusable instruction file that teaches an agent how to do one job well — the procedure, the tools, and what counts as done.
MCP — The Model Context Protocol — an open standard that lets any AI assistant plug into any tool or data source without custom integration code.
AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
embedding — A list of numbers representing a piece of text's meaning, so that similar meanings end up numerically close and can be searched.

Why it matters

Lets any MCP-compatible pull in Cua's desktop-automation know-how directly rather than reimplementing targeting and verification logic from scratch.
