ALWAYS use when building realtime features with Ably — messaging, chat, collaboration, presence, or AI token streaming. Covers product and SDK selection (Pub/Sub vs Chat vs Spaces vs LiveObjects), authentication (JWT, token auth, authUrl), channel design, React integration, and critical mistakes like missing Chat attach(), client-side API key exposure, and creating Ably clients inside components. Fetches current docs from ably.com/llms.txt before generating code. Not for general WebSocket or non-Ably realtime libraries.
React Native mobile development. Core components, navigation (React Navigation), platform-specific code, native modules, performance optimization, and debugging. USE WHEN: user mentions "React Native", "react-native", "mobile app with React", "cross-platform mobile", "RN", "react-native-cli" DO NOT USE FOR: Expo-specific features - use `expo`; Flutter - use `flutter`; web React - use `react` skills
Turn on Cache Components in a Next.js app and resolve the blocking routes it surfaces. Use when the user wants to enable, adopt, or migrate to Cache Components, flip the `cacheComponents` flag, work through a flood of blocking-prerender / instant validation errors, run the `cache-components-instant-false` codemod, or decide between opting routes out with `export const instant = false` and fixing them in place.
Analyze UI design screenshots and generate React components with TypeScript and Tailwind CSS. Use this skill when the user provides UI mockups, design screenshots, or Figma exports and requests implementation. Provides detailed layout analysis, component breakdown, design token extraction, and production-ready code generation following best practices.
Comprehensive security audit and vulnerability detection for JavaScript/TypeScript applications following OWASP Top 10. Use when (1) Users say 'audit security', 'check for vulnerabilities', 'security review', 'implement authentication', 'secure this code', (2) Adding authentication, API endpoints, file uploads, or handling user input, (3) Working with secrets, credentials, or sensitive data, (4) Implementing payment features or blockchain integrations, (5) Conducting pre-deployment security checks. Audits for: hardcoded secrets, injection vulnerabilities, XSS/CSRF, broken access control, insecure authentication, rate limiting, dependency vulnerabilities, sensitive data exposure.
Guide product managers through Jeff Gothelf's Lean UX Canvas v2—a one-page tool that frames work around a business problem, exposes assumptions, and ensures learning every sprint.
Connect to a running ComfyUI instance, queue workflows, monitor execution, and retrieve results. Supports both online (REST API) and offline (JSON export) modes. Use when executing ComfyUI workflows or checking server status.
Test at extremes (1000x bigger/smaller, instant/year-long) to expose fundamental truths hidden at normal scales
YC Office Hours — two modes. Startup mode: six forcing questions that expose demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit. Builder mode: design thinking brainstorming for side projects, hackathons, learning, and open source. Saves a design doc. Use when asked to "brainstorm this", "I have an idea", "help me think through this", "office hours", or "is this worth building". Proactively suggest when the user describes a new product idea or is exploring whether something is worth building — before any code is written. Use before /plan-ceo-review or /plan-eng-review.
Systematically improves TSDoc and README documentation across packages in a TypeScript monorepo. Discovers public API surfaces, generates or improves TSDoc on all exports, rewrites READMEs to a consistent retrieval-friendly structure, and commits each package independently. USE FOR: monorepo-wide documentation passes, single-package doc improvements, TSDoc generation on public exports, README standardization, review council quality checks. DO NOT USE FOR: runtime code changes, security scanning, API reference site generation, non-TypeScript languages.
Build immutable audit trails for all financial transactions with user attribution, change logging, tamper detection, and compliance-ready export for external audits
PDF to Word converts PDF to editable Word/DOCX with AI-powered layout analysis and table recognition, built on ComPDF Conversion SDK to better preserve tables, multi-column layouts, lists, and images for downstream editing. It fits requests such as “pdf to word,” “convert pdf to docx,” “pdf to editable word,” “pdf to office,” “keep layout in word,” and “convert report to docx.” Example queries include “Convert this PDF contract to editable Word while keeping the tables intact,” “Turn this report into DOCX and preserve the multi-column layout,” and “Export this PDF to Word for further editing.”
