Smart/Dumb component patterns, Standalone components, modern control flow (@if, @for), and OnPush strategy for Angular 17+.
Turn any concept into an animated explainer video using Manim (Python). Use whenever the user wants animated visualizations, motion graphics, or video output (MP4/GIF) for technical concepts. Covers: architecture animations, data flow visualizations, algorithm step-throughs, pipeline explainers, math proofs, comparisons, agent interactions, training loops, or any "animate X" / "make a video of X" request. Also trigger for existing Manim scene edits or re-renders. Trigger on: "create a video", "animate this", "make an explainer", "concept to video", "manim animation", "show this as a video", "motion graphic", "visualize this process", or any concept + video/animation output request. Use this skill even for casual "animate" requests about technical ideas.

Builds elaborate multi-component claude.ai HTML artifacts using React 18, TypeScript, Vite, Tailwind CSS, and shadcn/ui bundled into single-file deliverables. Use when asked to "create complex artifact", "build React artifact with routing", "use shadcn/ui components", "create stateful web app artifact", or "build multi-component frontend". Provides initialization scripts, development workflow, and Parcel bundling to create sophisticated single-HTML artifacts with state management and modern components. Works with React/TypeScript stack for claude.ai artifacts requiring complexity beyond simple HTML/JSX.
Use when creating data flow diagrams (DFD), functional decomposition trees, IDEF0 diagrams, or BPMN process models.

USE FOR: data flow diagrams (DFD), functional decomposition, IDEF0 modeling, BPMN process modeling, process analysis, data transformation visualization, system behavior documentation, input-output analysis DO NOT USE FOR: object-oriented modeling (use uml), system container decomposition (use c4-diagrams), enterprise architecture (use togaf or archimate)
Complete WordPress development workflow covering theme development, plugin creation, WooCommerce integration, performance optimization, and security hardening.
Generate architecture diagrams as .excalidraw files from codebase analysis, with optional PNG/SVG export. Use when the user asks to create architecture diagrams, system diagrams, data flow diagrams, parameter threading traces, call chain visualizations, visualize codebase structure, generate excalidraw files, export excalidraw diagrams to PNG or SVG, or convert .excalidraw files to image formats.
Battle-tested Playwright patterns for E2E, API, component, visual, accessibility, and security testing. Covers locators, assertions, fixtures, network mocking, auth flows, debugging, and framework recipes for React, Next.js, Vue, and Angular. TypeScript and JavaScript.

Style, review, and refactoring standards for Bash shell scripting. Trigger when `.sh` files, files with `#!/usr/bin/env bash` or `#!/bin/bash`, or CI workflow blocks with `shell: bash` are created, modified, or reviewed and Bash-specific quality controls (quoting safety, error handling, portability, readability) must be enforced. Do not use for generic POSIX `sh`, PowerShell, or language-specific application style rules. In multi-language pull requests, run together with other applicable `*-style-guide` skills.
Guides understanding and working with Apache Beam runners (Direct, Dataflow, Flink, Spark, etc.). Use when configuring pipelines for different execution environments or debugging runner-specific issues.
