bm-prd-creator
Guides you through turning a raw idea into a structured Product Requirements Document. Produces a complete prd.md plus a sequence of milestone prompt files you can hand to a coding agent to drive implementation.
/plugin install bm-prd-creator
bm-design-system
Scaffolds a complete design system into a React + Tailwind v4 codebase: a single-page reference at /admin/design-system that previews and documents every primitive, plus reusable shadcn-style components and managed instructions in AGENTS.md/CLAUDE.md so future agents always defer to the system instead of drifting.
/plugin install bm-design-system

bm-favicon-creator
Generates a complete favicon set from a Lucide icon (or another source SVG you point to) — a rounded square with your chosen background and icon colors — then writes favicon.ico, icon.svg, icon.png, and apple-touch-icon.png to public/ and wires the favicon meta tags into your layout.
/plugin install bm-favicon-creator
