Optimize documentation for AI coding assistants and LLMs. Improves docs for Claude, Copilot, and other AI tools through c7score optimization, llms.txt generation, question-driven restructuring, and automated quality scoring. Use when asked to improve, optimize, or enhance documentation for AI assistants, LLMs, c7score, Context7, or when creating llms.txt files. Also use for documentation quality analysis, README optimization, or ensuring docs follow best practices for LLM retrieval systems.
Expert guide for implementing Feature-Driven Development (FDD) architecture in frontend projects (React/TypeScript). Use when: (1) Creating new features, (2) Refactoring or migrating a legacy folder structure to FDD, (3) Initializing a new project layout, (4) Reviewing whether code follows FDD principles. Enforces strict feature isolation, clear public APIs via index.ts barrel files, and scalable feature organization.
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of "Word doc", "word document", ".docx", or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a "report", "memo", "letter", "template", or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
A skill for designing, building, validating, and securing n8n automation workflows, using specialized AI personas (Build Captain, QA, Security Architect). Use this skill to create production-ready n8n workflows from plain language specifications.
Expert UI component builder and OpenAI SDK integrator. Use when building or refactoring React components using the `@openai/apps-sdk-ui` library to ensure visual consistency, logic-driven variant selection, and adherence to specific workspace conventions (Anti-Pill rule, uniform icons).
Systematically analyze an unfamiliar codebase and produce a structured onboarding guide plus a starter AGENTS.md for Antigravity CLI (Google's terminal coding agent). Use this skill when the user says "onboard me", "help me understand this codebase", "generate an AGENTS.md", "set up Antigravity for this project", "I'm new to this repo", or asks for a project instructions file for Antigravity, agy, Gemini CLI, or cross-tool agent compatibility. Also trigger when the user wants to create or update any AGENTS.md file.
Behavioral guidelines for reducing LLM coding mistakes, derived from Andrej Karpathy's observations. Use when writing, reviewing, or refactoring code to ensure simplicity, surgical changes, and verifiable success. Essential for maintaining the high-quality standards of Antigravity Kit.
Rédige un Cahier des Charges (CdC) professionnel pour application mobile ou web en français. Ce skill transforme les spécifications techniques (requirements.md, design.md) en un document de cadrage formel. Il met l'accent sur les objectifs stratégiques, l'expérience utilisateur (UX/UI), les fonctionnalités détaillées, les contraintes techniques (iOS/Android, Swift/Kotlin) et la collaboration client-développeur.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
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). Generates creative, polished code and UI design that avoids generic AI aesthetics.
Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.
Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
A set of resources to help me write all kinds of internal communications, using the formats that my company likes to use.
