Engineering Skills Toolkit

Search the web, scrape URLs into markdown/HTML/screenshots/links/images, extract structured JSON with AI prompts, crawl multi-page sites, and monitor pages for changes on a schedule. Supports browser automation features like JavaScript rendering, stealth mode, cookies, and custom headers. Perfect for data engineers, researchers, and developers who need API-free web data collection without writing scrapers.

This comprehensive skill collection guides you through creating professional videos programmatically using Remotion and React. Create new video projects, structure complex multi-scene compositions, and animate content with full interactivity. Add captions by transcribing audio, importing SRT files, or generating them programmatically. Build animated maps with Mapbox, MapLibre, or GeoJSON, including 3D geographic flyovers. Process multimedia by trimming, cropping, and extracting metadata from video and audio files.

Render dynamic videos directly from HTML/code using Puppeteer and ffmpeg, with built-in support for AI voiceover, caption overlays, and motion animation. Convert markdown changelogs into polished 45-60 second branded videos with animated UI mockups, captions, and AI narration. Create explainer videos, product demos, and animated visualizations using code-first workflows and motion doctrines that enforce consistency and quality.

Create production-ready mobile app designs by describing what you want in plain language. Use chat-based requests to design screens, iterate with follow-up messages, and export code implementations for HTML, React Native, and SwiftUI. Features include live design preview in the Sleek editor, component screenshot generation, and built-in design references to seed your visual style.

Present users with an adaptive 24-question personality assessment that uses Bayesian active learning to efficiently map their psychological profile. The skill automatically maps user responses (1-7 scales or natural language) to archetype classifications based on a 5-color psychological model, tracks probability distributions in real-time, and delivers detailed personality insights including core strengths, weaknesses, and top archetype matches.

Access 30+ RunComfy model endpoints directly from Claude Code, including image-to-video, video-editing, AI image generation, AI video generation, and music composition. Each skill wraps a production endpoint with schema validation and intent-based routing. Use the RunComfy CLI to generate, inpaint, outpaint, and transform media from ACE Step music (tag-driven, $0.0002/s) to video and image models. Skills route automatically based on your request intent.

Design and build animations using a proven decision sequence covering when to animate, which tools to use (CSS, WAAPI, Motion.dev), property selection, easing curves, and accessibility. Review existing animations and audit codebases for quality issues. Understand and name motion effects using a comprehensive vocabulary glossary. Learn from Emil Kowalski's opinionated motion design philosophy built on decades of interface engineering experience.

This collection of skills improves code quality, architecture documentation, and team workflow coordination. Review Architecture Decision Records with fresh perspective and rewrite them for clarity, implement type-safe AST visitor patterns for robust code organization, automate Biome linting upgrades across monorepos, and generate well-structured GitHub pull requests integrated with Linear project tracking. Perfect for teams that care about maintainable code, clear decision documentation, and smooth development workflows.
