Machine Learning

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI).

Build accessible user interfaces following WCAG guidelines with semantic HTML, keyboard navigation, screen reader support, and proper color contrast. Use this skill when creating or modifying UI components, implementing form inputs, adding interactive elements, working with navigation menus, creating modals or dialogs, or handling focus management. Apply when working on React component files (*.tsx, *.jsx), Shadcn/ui components, or any frontend code that users interact with. This skill ensures semantic HTML elements (nav, main, button, etc.) that convey meaning to assistive technologies, keyboard navigation with visible focus indicators (focus:ring-2 focus:ring-offset-2 in Tailwind), sufficient color contrast ratios (4.5:1 for normal text), descriptive alt text for images and meaningful labels for form inputs, screen reader testing and verification, ARIA attributes for complex components when semantic HTML isn't sufficient, logical heading structure (h1-h6 in proper order), and proper focus management in dyna

Build accessible web interfaces following WCAG guidelines and assistive technology best practices. Use this skill when creating or modifying UI components that need keyboard navigation, screen reader support, or ARIA attributes. When working on files like components/, pages/, or any file with interactive elements, forms, modals, or dynamic content. When adding alt text to images, labels to form inputs, or managing focus in single-page applications. When implementing color contrast, heading structure, or semantic HTML elements.

Interpretive guidance for Prettier code formatting across multiple file types (JS/TS, YAML, JSON, CSS, HTML). Use when configuring Prettier, troubleshooting formatting issues, or understanding tool selection for these file types.

Write comprehensive test coverage across unit, integration, regression, end-to-end, and manual tests. Watch for deprecation warnings in test output and address them immediately. Use when writing tests, implementing features, or before creating pull requests.

Templates and patterns for common ML training scenarios including text classification, text generation, fine-tuning, and PEFT/LoRA. Provides ready-to-use training configurations, dataset preparation scripts, and complete training pipelines. Use when building ML training pipelines, fine-tuning models, implementing classification or generation tasks, setting up PEFT/LoRA training, or when user mentions model training, fine-tuning, classification, generation, or parameter-efficient tuning.

Deploy containerized web applications to any Linux server using Kamal. Use when users need to deploy, configure, debug, or manage Kamal deployments including initial setup, configuration of deploy.yml, deployment workflows, rollbacks, managing accessories (databases, Redis), troubleshooting deployment issues, or understanding Kamal commands and best practices.

Guide for creating new skills following best practices. Creates properly formatted SKILL.md files with YAML frontmatter, clear structure, and effective discovery metadata.

Comprehensive agent creation reference including YAML frontmatter requirements, tier classification, cognitive architecture, constitutional patterns, and archetype selection. Use when creating or validating HestAI agents, ensuring proper structure and discovery. Triggers on create agent, agent structure, YAML frontmatter, agent validation, tier classification, archetype selection, OCTAVE agents.

Generate PPTX-compatible HTML slide decks for math worked examples. Use when user says "create worked example" or needs visual step-by-step math instruction with CFU questions and practice problems.

Manages local web server lifecycle and enables web page development with Playwright MCP. Use when developing HTML/CSS/JS, building web pages, viewing web pages, testing UI interactions, verifying renders, debugging frontend issues, or iterating on web design. Covers build, startup, shutdown, and browser-based testing workflows.

Create distinctive, production-grade frontend interfaces with high design quality.
