This booster enables OS-level desktop and window screenshot capture when users explicitly request it or when tool-specific capabilities are unavailable. Developers and AI assistants benefit from having a fallback capture mechanism for debugging, documentation, and UI inspection tasks.
Generates repository-grounded threat models that identify trust boundaries, assets, attack paths, and mitigations in application code. Ideal for security engineers and developers performing AppSec threat modeling on specific codebases.
Use this skill to create or update full-page screens in Figma by reusing the published design system — components, variables, and styles — rather than drawing primitives with hardcoded values. The key insight: the Figma file likely has a published design system with components, color/spacing variabl
This skill helps you connect Figma design components to their corresponding code implementations using Figma's Code Connect feature. It analyzes the Figma design structure, searches your codebase for matching components, and establishes mappings that maintain design-code consistency. Call to identi
A skill that helps developers create distinctive, production-grade frontend interfaces with polished aesthetics and creative design choices, avoiding generic AI-generated outputs. Ideal for developers building web components, pages, and applications who want professional design quality.
