Placed #5 of 6 in the judged category final for Prompt design & optimisation.

Not launch-quality. It is graded C with a clean safety verdict, but our quality filters exclude it: it is a near-duplicate variant of another skill. So it is not in our launch-quality set, the skills our MCP server searches and recommends. How launch-quality is decided

Our two independent classifiers differ on this skill's category, so treat the placement as provisional.

A well-indexed wrapper around the 240+-pattern Fabric prompt library with a built-in upstream-sync workflow, though its own value-add is thin since pattern content lives in an external repo.
