<!-- INTENTIONALLY INERT. This skill ships NO grounding content. It exists only to
attach the package-grounding MCP server (see plugin.json) to the evaluated run so
the agent self-selects whether to retrieve context via the get_package_context
tool. The retrieval gate under test lives in the tool's description, not here. -->
