pencil-design

Use this skill for any pencil.dev work, such as designing UI in a .pen file, editing an open Pencil canvas, sketching or mocking screens, instantiating components from a .lib.pen library, reading an existing design system from a .pen or .lib.pen file, fixing batch_design schema errors, or recovering from Pencil MCP host-not-connected issues. Pick it on any mention of pencil.dev, .pen, .lib.pen, "the Pencil MCP", "the Pencil canvas", or a design-system/ folder in a Pencil context, even when the user phrases it casually, mid-sentence, or doesn't name the tool. This is the canonical skill for all Pencil tasks; reach for it before any general design or frontend skill when Pencil signals are present.
