+name: FastMCP Python Guidance
+description: Route FastMCP Python changes to the Personal MCP source-reference skill.
+applyTo: '**/*.py'
+---
+
+A core part of this repository is [FastMCP](https://gofastmcp.com/servers/server).
+
+For FastMCP implementation or protocol questions, load `skill://mcp-details/SKILL.md` first.
+
+Inspect `skill://mcp-details/_manifest` only when a source reference is needed, then read the relevant supporting path. For FastMCP Python APIs, prefer the supporting reference that covers SDKs and FastMCP.
+
+This repository is resource-first and exposes resources as tools only as a fallback. In tool-only clients, use `list_resources` and `read_resource` with the same `skill://` URIs.
+
+Reconcile the skill guidance with the installed FastMCP version and the repository's existing implementation before editing.
