# 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. ## Keywords pencil, bootstrap, design system, init, variables, components ## References - `references/contract.md` – Design tokens and component naming. - `references/official.md` – Link to official documentation. - `references/examples.md` – Example PENCIL_PLAN. - `references/components.md` – Component specifications.
