Extracts design tokens from images and generates CSS custom properties, atomic utility classes (Tailwind-style), and platform-specific formats following W3C standards and modern CSS best practices.

Update specific design document with new content or metadata. Use when modifying design docs, updating status/completeness, or syncing after code changes.

Validate design doc structure and frontmatter. Use when checking design docs for compliance, ensuring proper formatting, or verifying metadata before commits.

Expert UI designer for building responsive, accessible web interfaces with Tailwind CSS v4 and Tailwind Plus components. Use when building websites, landing pages, web applications, UI components, forms, navigation, layouts, e-commerce pages, or marketing pages.

Design custom syntax elements with reuse-first approach for workflow orchestration. Use when user needs custom operators, checkpoints, or syntax patterns not available in core syntax.

Generate end-to-end tests for the complete Desktop Ethereal application, including UI interactions, system integration, and user workflows. Triggers on E2E testing, Playwright, system testing, or complete application testing requests.

Electron desktop development guide. Use when implementing desktop features, IPC handlers, controllers, preload scripts, window management, menu configuration, or Electron-specific functionality. Triggers on desktop app development, Electron IPC, or desktop local tools implementation.

Generates detailed implementation plans from a SINGLE plan-based-page output file. Supports parallel execution - run multiple sessions simultaneously for different pages. Input is ONE file (either _shared-components.md or a specific page like landingpage-page.md). Use when you want to generate implementation plans in parallel across multiple sessions.

Detects SpecWeave context and provides workflow documentation for available commands. Use when learning SpecWeave commands, understanding available slash commands (/sw:increment, /sw:do, /sw:progress, /sw:done), or getting workflow guidance. Explains command syntax and recommended workflow patterns.

Production-grade API design patterns for REST, GraphQL, gRPC, and tRPC. Covers API architecture, OpenAPI/Swagger specs, versioning/deprecation, authentication/authorization, rate limiting, pagination, error models, contract testing, and developer documentation.

Autonomous development workflow. Generate detailed specs, plans, and tasks for autonomous agent execution with session memory tracking.

Use dev-browser for browser automation on NixOS. Invoke when user asks to test UI, automate browser interactions, take screenshots, or verify web app behavior.

Context architecture skill for aligning work. Use when starting new features, making architectural decisions, or setting up implementation work. Generates interconnected ADR/Design/Spec/Plan scaffolding that agents can navigate and humans can enrich.

<!-- SKILL CHAINING: After completing debugging work, Claude MUST invoke related skills -->

REQUIRED Phase 2 of /dev workflow after dev-brainstorm. This skill should be used when the user asks to 'explore the codebase', 'map architecture', 'find similar features', 'discover test infrastructure', 'trace execution paths', 'identify code patterns', or needs to understand WHERE code lives and HOW it works before implementation. Launches parallel explore agents and returns prioritized key files list.
