FastMCP 4.2 ships Skills as first-class MCP objects, delivering expertise alongside tools

FastMCP 4.2 makes Skills a first-class Python object in MCP: the same server exposing tools can also distribute the skills for using them — via SKILL.md files, whole directories, or skills defined on the fly in code (no SKILL.md needed).
- Author Jeremiah Lowin's argument: MCP tools expose business logic; skills provide behavioral guidance. The skills-vs-MCP debate was always strange — they're complementary
- Example: a deployment platform's MCP server lets agents inspect deployments, read logs, roll back; the team can package its operational knowledge (investigating failed rollouts, pre-revert checks) as a skill served alongside the tools
- The next connecting agent discovers both; expertise ships with the product — "a much more interesting thing to distribute than an API wrapper"
