The article argues that using "skills" is a more efficient way to provide agents with external capabilities than using MCP (Multi-Call Protocol). MCP can lead to "context bloat" by loading extensive tool definitions, descriptions, and schemas into every session, even when not needed. This consumes valuable context tokens that could be used for the actual task. Skills, on the other hand, load only a lightweight name and description initially, with detailed instructions and supporting files loaded progressively as needed. This approach saves tokens and improves model performance by keeping the active working set focused on the user's request. AI
IMPACT Adopting skills over MCP can lead to more efficient AI agent performance and reduced operational costs by optimizing context token usage.
