Generate Office documents (DOCX, XLSX, PDF, PPTX) with TypeScript. Pure JS libraries that work everywhere: Claude Code CLI, Cloudflare Workers, browsers. Uses docx (Word), xlsx/SheetJS (Excel), pdf-lib (PDF), pptxgenjs (PowerPoint). Use when: creating invoices, reports, spreadsheets, presentations, form filling, exporting data to Office formats, or troubleshooting "Packer.toBuffer", "XLSX.utils", "PDFDocument", "pptxgenjs" errors.
Senior Front-End Developer expertise in ReactJS, NextJS, JavaScript, TypeScript, HTML, CSS, and modern UI/UX frameworks
Extract clean markdown or text content from specific URLs via the Tavily CLI. Use this skill when the user has one or more URLs and wants their content, says "extract", "grab the content from", "pull the text from", "get the page at", "read this webpage", or needs clean text from web pages. Handles JavaScript-rendered pages, returns LLM-optimized markdown, and supports query-focused chunking for targeted extraction. Can process up to 20 URLs in a single call.
Provides TypeScript patterns for type-first development, making illegal states unrepresentable, exhaustive handling, and runtime validation. Must use when reading or writing TypeScript/JavaScript files.
Creating interactive data visualisations using d3.js. This skill should be used when creating custom charts, graphs, network diagrams, geographic visualisations, or any complex SVG-based data visualisation that requires fine-grained control over visual elements, transitions, or interactions. Use this for bespoke visualisations beyond standard charting libraries, whether in React, Vue, Svelte, vanilla JavaScript, or any other environment.
Work with the Upstash Redis JavaScript/TypeScript SDK for serverless Redis operations. Use for caching, session storage, rate limiting, leaderboards, full-text search, and all Redis data structures. Supports automatic serialization/deserialization of JavaScript types.
Setup Sentry Tracing (Performance Monitoring) in any project. Use when asked to enable tracing, track transactions/spans, measure latency, or add performance monitoring. Supports JavaScript, Python, and Ruby.

Router for web form development. Use when creating forms, handling validation, user input, or data entry across React, Vue, or vanilla JavaScript. Routes to 7 specialized skills for accessibility, validation, security, UX patterns, and framework-specific implementations. Start here for form projects.
Explore any codebase from scratch and generate six quality artifacts: a quality constitution (QUALITY.md), spec-traced functional tests, a code review protocol, an integration testing protocol, a multi-model spec audit (Council of Three), and an AI bootstrap file (AGENTS.md). Works with any language (Python, Java, Scala, TypeScript, Go, Rust, etc.). Use this skill whenever the user asks to set up a quality playbook, generate functional tests from specifications, create a quality constitution, build testing protocols, audit code against specs, or establish a repeatable quality system for a project. Also trigger when the user mentions 'quality playbook', 'spec audit', 'Council of Three', 'fitness-to-purpose', 'coverage theater', or wants to go beyond basic test generation to build a full quality system grounded in their actual codebase.
Design, implement, and refactor Ports & Adapters systems with clear domain boundaries, dependency inversion, and testable use-case orchestration across TypeScript, Java, Kotlin, and Go services.
