pennylane
Hardware-agnostic quantum ML framework with automatic differentiation. Use when training quantum circuits via gradients, building hybrid quantum-classical models, or needing device portability across IBM/Google/Rigetti/IonQ. Best for variational algorithms (VQE, QAOA), quantum neural networks, and integration with PyTorch/JAX/TensorFlow. For hardware-specific optimizations use qiskit (IBM) or cirq (Google); for open quantum systems use qutip.
entry-point-analyzer
Analyzes smart contract codebases to identify state-changing entry points for security auditing. Detects externally callable functions that modify state, categorizes them by access level (public, admin, role-restricted, contract-only), and generates structured audit reports. Excludes view/pure/read-only functions. Use when auditing smart contracts (Solidity, Vyper, Solana/Rust, Move, TON, CosmWasm) or when asked to find entry points, audit flows, external functions, access control patterns, or privileged operations.
software-architecture
Provides concrete coding guidelines based on Clean Architecture and DDD principles, emphasizing library-first approach and avoiding common anti-patterns like NIH syndrome. Focuses on practical rules for function length, naming conventions, and separation of concerns.
skill-creator
Design effective Claude Code skills with optimal descriptions, progressive disclosure, and error prevention patterns. Covers freedom levels, token efficiency, and quality standards. Use when: creating new skills, improving skill descriptions, optimizing token usage, structuring skill content, or debugging why skills aren't being discovered.
favicon-gen
Generate custom favicons from logos, text, or brand colours. Produces all required formats: favicon.svg, favicon.ico, apple-touch-icon.png, icon-192/512.png, and web manifest. Use when initialising websites, replacing CMS default favicons, converting logos to favicons, creating branded icons from initials, or troubleshooting favicon not displaying, iOS black square, or missing manifest.
office
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.
compatibility-testing
Provides concrete guidance for cross-browser and cross-platform compatibility testing with specific browser matrices, screen breakpoints, and code examples for Playwright and BrowserStack integration. Focuses on testing actual user environments rather than developer setups.
ultrathink-detective
A specialized Claude skill that enforces AST-based code analysis using claudemem v0.3.0, prohibiting grep/find/glob. Provides structured workflows for architecture mapping, dependency tracing, and impact analysis through six distinct analysis dimensions with clear command patterns.
