Official MCP extension lets agents discover and load Skills directly from MCP servers

The official MCP repo modelcontextprotocol/ext-skills (SEP-2640) defines a standard way to discover and load Agent Skills from MCP servers:
- Flow: connect to an MCP server → discover available skills → inspect skill metadata → load the relevant SKILL.md only when needed.
- Under the hood, Skills are served through MCP's existing Resources primitive: SKILL.md, references, scripts and examples are exposed as on-demand resources.
- Key value is context window management: instead of loading every workflow instruction upfront, the agent discovers what's available and pulls in only the skill required for the current task.
- Mental model: tools = what the agent can do; resources = what the agent can access.
