ECharts Design System Initializer

Constraint: Only use this skill when the user explicitly mentions "Pencil" and "ECharts" or when orchestrating a Pencil design system initialization task for charts.

When to use this skill

Use this skill when:

• The user wants to initialize ECharts chart theme tokens (colors, axis, text) in a Pencil .pen file
• The user needs placeholder frames for ECharts chart types (Line, Bar, Pie, Scatter, Radar, Gauge)
• The user mentions "Pencil" together with "ECharts" or chart visualization components
• An orchestrator skill (pencil-ui-designer) routes an ECharts initialization request

How to use this skill

This skill outputs a PENCIL_PLAN. The Agent then calls Pencil MCP tools in order: open_document, set_variables, batch_design, optionally get_screenshot.

Step 1: Initialize Variables (set_variables)
