Reviews React/Vue component architecture, state, and hooks. Use when junior builds components, forms, modals, uses useState, useEffect, adds state, or asks "is this good React".
mirror-development
Implement user impersonation features in Laravel applications using Mirror.
remotion-video
Create production-grade motion graphics and videos using Remotion (React). Use whenever the user wants branded video content, product demos, data-driven video generation, or motion graphics with audio sync, web fonts, TailwindCSS styling, or media embedding. Covers: marketing videos, product launches, data visualizations, social media content, personalized video at scale, explainer videos with voiceover, animated charts, 3D scenes via Three.js. Requires Node.js and Claude Code environment. Trigger on: "create a Remotion video", "React video", "motion graphics", "branded video", "product demo video", "remotion", "video with audio", "TailwindCSS video", "data-driven video generation", "personalized video at scale", "video with voiceover". For mathematical animations, algorithm visualizations, or headless container rendering, use concept-to-video (Manim) instead.

parallel-task-spark
Only to be triggered by explicit /parallel-task-spark commands.
filesystem
File and directory operations using Claude Code built-in tools โ replaces the Filesystem MCP server. Maps all 11 MCP tools to native equivalents: Read, Write, Edit, Glob, Grep, and Bash. Covers file reading with line ranges, parallel reads, pattern-based file search, regex content search, directory listing, tree traversal, move/copy/rename, and metadata inspection. Trigger phrases: "read this file", "write to file", "create a file", "edit file", "find files matching", "search for text in files", "list directory", "show directory tree", "move file", "rename file", "copy file", "file info", "find all Python files", "search codebase for". Use this skill when performing file operations, navigating codebases, or managing directories.
feature-builder
Build complete React features with proper layered architecture including UI components, business logic, API integration, and state management. Use this skill when users request implementing features like "user authentication", "shopping cart", "product listing", "file upload", or any complete functionality that requires UI + business logic + data fetching. Generates all layers - presentation (components), business logic (hooks/stores/validation), and data access (API calls/React Query). Integrates with react-component-generator for UI and provides production-ready, maintainable code following best practices.
engineering-standards
Core software engineering principles (SOLID, DRY, YAGNI, KISS) with detection patterns and refactoring guidance. Load when reviewing code quality, planning architecture, or identifying technical debt.
setup-mcp-server
Add mcp-rubber-duck MCP server to an AI coding tool (Claude Desktop, Cursor, VS Code, Windsurf, etc.)
game-control
Control a running Tiny game engine via HTTP. Send key presses, releases, and taps to interact with the game. Use when the user asks to play, control, test, or interact with a running game.
context-loader
ALWAYS activate this skill at the start of every task. Load project context from .claude/ directory including coding rules, design decisions, and documentation before executing any task.
performance
Performance optimization guidelines for Splitrail. Use when optimizing parsing, reducing memory usage, or improving throughput.
agentic-ux-design-relationship-centric-interfaces
Design AI-first interfaces that build ongoing relationships through memory, trust evolution, and collaborative planning, not just isolated screen interactions
update-dependencies
Update packages that DCP executables depend on. This skill is used infrequently, usually just once at the start of a new development cycle. Should only be used when requested explicitly, never as part of a regular change or PR.
release-new-version
Release a new version of this Obsidian plugin by bumping the npm/package version, syncing `manifest.json` and `versions.json`, and pushing the resulting git tag. Use when the user asks to cut a release, bump the version, publish a new version, or push a release tag.
react-router-framework-mode
Build full-stack React applications using React Router's framework mode. Use when configuring routes, working with loaders and actions, handling forms, handling navigation, pending/optimistic UI, error boundaries, or working with react-router.config.ts or other react router conventions.
