Skill-Centric Workflow: An antidote to the Context Window Problem (Building an Agent).
In the rapidly evolving world of AI agents, we’re witnessing a fascinating "clash of the titans" (or rather, a partnership) between two architectural heavyweights: the Model Context Protocol (MCP) and Agent Skills . If MCP provides the "arms and legs" for an agent to reach into external databases and apps, Agent Skills act as the "brain and playbook." But there’s a quiet crisis brewing in the background: the Context Window Tax. Here is why Agent Skills are becoming the secret weapon for developers looking to keep their MCP-powered agents from drowning in their own data. The "Context Window Tax": MCP’s Hidden Burden The Model Context Protocol is a breakthrough for interoperability, but it has a notorious overhead problem. In a traditional MCP setup, a client (like Claude or a custom agent) often calls tools/list to discover every capability a server offers. The problem? JSON schemas are wordy. If you connect three robust MCP servers (say, ...
