Bootstrap Design System Initializer

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

When to use this skill

Use this skill when you need to initialize a new design system based on Bootstrap specifications, specifically to set up the global color palette and create the initial component library frames in a .pen file.

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)

Use mcp__pencil__set_variables to register Bootstrap design tokens. Follow .pen file schema.

Primary / Semantic

  • bs-primary: #0d6efd
  • bs-secondary: #6c757d
  • bs-success: #198754
  • bs-danger: #dc3545
  • bs-warning: #ffc107
  • bs-info: #0dcaf0
  • bs-light: #f8f9fa
  • bs-dark: #212529

Body & Border

  • bs-body-color: #212529
  • bs-border-color: #dee2e6
  • bs-border-radius: 0.375rem (6px)

Font

  • bs-font-size-base: 1rem (16px)

Fill from Bootstrap Sass variables / CSS variables if more tokens are needed.

Step 2: Create Component Overview Structure (batch_design)

Use mcp__pencil__batch_design to create a "Components Overview" frame with sections based on Bootstrap documentation:

  1. Layout
    • Container, Grid, Stack
  2. Content
    • Typography, Images, Tables
  3. Forms
    • Form, Input, Select, Checkbox, Radio, Switch, Range
  4. Components
    • Accordion, Alert, Badge, Breadcrumb, Buttons, Button group, Card, Carousel, Close button, Collapse, Dropdowns, List group, Modal, Navbar, Offcanvas, Pagination, Placeholders, Popovers, Progress, Scrollspy, Spinners, Toasts, Tooltips
  5. Utilities
    • Borders, Colors, Display, Flex, Float, Spacing

Organize frames using Auto Layout. Keep each batch_design call to maximum 25 operations.

Best Practices

  • Verify token values against Bootstrap docs (Sass/CSS variables).
  • Use set_variables with replace: false unless a full reset is requested.
  • Use Auto Layout for component overview frames.
